  • Fishery Production Potential of the Mangroves in India - A Review

    • Authors: S. BIJOY NANDAN, S. SREELEKSHMI, M. HARIKRISHNAN
      Abstract: Mangroves support and enhance fisheries by serving as a breeding ground and nursery habitat for aquatic life. While mangroves are widely recognized for their role in enhancing both small scale and commercial fisheries, they are rapidly disappearing. The understanding of this ecosystem service and its value in both social and economic terms will help enhance the sustainable management of both mangroves and fisheries. This paper provides a critical review of mangroves and their importance in capture fisheries and also discusses the ecological significance of this ecosystem in fisheries enhancement by explaining the different mangrove associated fisheries. As the fisheries value of mangroves is highly site-specific, the paper illustrates the drivers and values of mangrove associated fisheries. Decision-makers can use this information to make decisions relating to conservation and restoration of mangrove ecosystems and sustainable fishing.

  • Jellyfish Species Used as Live Baits in Traditional Trap Fishery of Sri
           Lanka: Acromitus flagellatus and Lychnorhiza malayensis (Cnidaria:
           Scyphozoa)

    • Authors: KRISHAN D. KARUNARATHNE, M. D. S. T. DE CROOS
      Abstract: Two species of scyphozoan jellyfish were observed to be used as live baits in a traditional small-scale trap fishery operated in the eastern Sri Lanka. However, there was limited taxonomic knowledge on the respective scyphomedusae. Therefore, altogether 83 specimens of these jellyfishes netted from several coastal localities of the country from 2016 to 2020 and eight museum specimens were examined taxonomically to reveal their identity. Of the species identified, Acromitus flagellatus was reported for the first time from Sri Lanka while Lychnorhiza malayensis was re-reported and these two species are presented here with detailed descriptions. As both species are mild stingers, so far no severe health issues have been reported in Sri Lanka. However, as bloom-forming species clogged jellyfish have adversely affected gillnet, trammel-net, and stake-net operations in coastal water bodies of Sri Lanka by reducing fish catches and damaging nets.Â

  • Live Jellyfish-baited Small-scale Traditional Trap Fishery Operated off
           the Eastern Coast of Sri Lanka

    • Authors: KRISHAN D KARUNARATHNE, G. W. A. DE ALWIS, M. D. S. T DE CROOS
      Abstract: The jellyfish-baited trap fishery was studied at four fishing grounds off the eastern coast of Sri Lanka throughout the entire fishing season (February and March) in three consecutive years, from 2017 to 2019, due to its uniqueness of export-oriented small-scale fishery. The composition of catch and their respective stomach content analysis revealed that the highly expensive Malabar groupers, which are predominantly targeted for export markets get attracted to traps as the secondary catch because they predate on the primary catch, e.g., filefishes, rabbitfishes, surgeonfishes and triggerfishes, and the bycatch, i.e., angelfishes and butterflyfishes. The varieties of primary catch are attracted to the jellyfish-bait. Among the 24 species of fishes caught, medusivorous Siganus javus had the highest abundance (24%), followed by Acanthurus mata (21%). Family-wise, the maximum contribution to the total catch was by Siganidae (56%), followed by Acanthuridae (34%). The average CPUE (kg three-man group-1 boat-1 day-1) ± SD of primary, secondary and by-catch during the fishing season was 87.0 ± 18.4 kg (~80%), 15.1 ± 3.4 kg (~14%) and 6.3 ± 1.4 kg (~6%) respectively, while the average total catch per trap was 7.2 ± 1.4 kg. The results of this study are important for utilizing the commonly available jellyfish bait to expand this trap fishery as well as to adapt the strategies for similar fisheries.

  • Feasibility Study of Green Mussel Perna viridis Farming in the Southeast
           Coast of the Bay of Bengal of Bangladesh

    • Authors: N. F. HOQUE, A. SHAKIL, F. SULTANA, M. A. WAHAB, M. J. RAHMAN, M. NAHIDUZZAMAN, S. AKTER, M. ASADUZZAMAN
      Abstract: Green mussel farming in coastal waters is on the edge of aquaculture trends for its worldwide acceptability as a supreme delicacy and an inexpensive protein source. The coastal water of Bangladesh has one of the world’s richest ecosystems with high productivity of fisheries due to the geographical location in the tropical climate zone, high rainfall and enrichment of water nutrients through the surface of the wide Gangetic river systems. This study aims to assess the feasibility of green mussel (Perna viridis) culture in the southeast coast of the Bay of Bengal, emphasizing coastal landlocked channels and estuary. Site capability rating system was applied based on the biophysical parameters and natural food requirements for the fast and effective evaluation of potential sites of green mussel farming. The year-round monthly variations of environmental parameters and plankton composition were recorded from seven potential sites Moheshkhali Channel, Rezu Khal and Naf River. Based on the biophysical parameters, Rezu Khal area is ranked as unsuitable/less suitable for green mussel culture mainly due to shallow water depth, high turbidity, lower food availability and higher temporal salinity fluctuation caused by the freshwater run-off during the monsoon season. However, Moheshkhali Channel and Naf River are medium to good sites based on suitability rating points, indicating that these sites are most suitable for commercial green mussel farming. Moreover, high chlorophyll-α and plankton abundance in these sites ensure that natural food availability is adequate to sustain green mussel farming. The present study findings would be applicable for the planning and development of a sustainable green mussel farming system in Bangladesh and elsewhere.

  • Quantification and Visualization of the Variability of Phytoplankton
           Assemblage in a Semi-lotic Seasonal Canal in Sundarbans, India

    • Authors: ARCHANA SINHA, PRANAB GOGOI, TASSO TAYUNG, SOMA DAS SARKAR, K. LOHIT KUMAR, ARUNAVA MITRA, V. R. SURESH, BASANT KUMAR DAS
      Abstract: Canals of Sundarbans in India are highly vulnerable to anthropogenic pressures which directly or indirectly impact the biological components of such ecosystems. Being at the base of the trophic pyramid, phytoplankton is exposed to environmental stressors and the impact will be reflected in the upper strata of the aquatic food chain. Hence, phytoplankton communities along with their interrelationship with environmental parameters were assessed in Bhetkimari canal, a semi-lotic system in Indian Sundarbans during June 2017 to September 2018. Seventy-seven species under 66 genera were recorded with Cyanophyceae (34%) as a major contributor, followed by Bacillariophyceae (31%) and Chlorophyceae (22%). Diatoms dominated round the year in terms of diversity (25 species) with maximum contribution from Pennales. ANOVA (post-hoc test) showed significant temporal heterogeneity (p≤0.05) in phytoplankton distribution in the canal. The Margalef richness index (d) and Shannon-Weiner diversity index (H′) were 2.59±0.43 and 2.26±0.59, respectively indicating that the environment is good and phytoplankton diversity in the system is moderate. Water temperature, dissolved oxygen, total alkalinity and nutrients (nitrate, silicate and phosphate) were the explanatory variables in shaping the phytoplankton assemblages in the canal, which was evident from Canonical correspondence analysis. The salient findings of this study can add to the existing knowledge on the abundance and distribution pattern of phytoplankton in semi-lotic canal environments, and help in planning better management of canal ecosystems for their sustainable utilization.

  • Think Ecosystems: Healthy Ecosystems are the Foundation for Sustainable
           and Integrated Coastal Management

    • Authors: ANDERS F. POULSEN
      Abstract: The coming decade will be extremely important in terms of steering the world onto a sustainable development path as we are facing multiple global challenges from climate change, biodiversity loss, pandemics, poverty, and inequality. The global community increasingly recognizes the urgency, for instance through its commitment towards fulfilling the Sustainable Development Goals (SDG) by 2030. This “deadline” coincides with a recent declaration by the United Nations (UN) to declare the decade 2021 to 2030 as the Decade of Ecosystem Restoration, recognizing the crucial role that nature and ecosystems play for sustainable development. Coastal areas are particularly vulnerable, exposed as they are to the impacts of climate change, and with large coastal populations dependent on, and often competing for, dwindling coastal resources. Sector-based coastal resource management is no longer an option as broader, ecosystem-based management frameworks are needed, that include all coastal sectors and acknowledge the values of ecosystems as foundations for sustainable resource utilization, and as solutions towards adapting to climate change. If more holistic approaches to coastal management have been adopted that build on the true values of nature and ecosystems, it will be possible to manage coastal resources and biodiversity in a sustainable manner that creates synergies and co-benefits rather than causing conflicts between stakeholders and sectors. For this to happen, some challenges need to be overcome. First, all the coastal stakeholders, including in particular the coastal communities, have to be brought together and be part of the decision-making process and management plans. Second, the existing institutional structures have to be transformed to ensure better collaboration and coordination across the current sector and institutional boundaries. This paper discusses some emerging trends in integrated coastal resources management, and outline needs for the world and its coasts to enable the move towards a sustainable future.

  • Environmental Management of Fish Cage Aquaculture

    • Authors: PATRICK G. WHITE
      Abstract: Most modern fish culture involves the intensive input of nutrients in the form of feed, yet only a small proportion of these nutrients is converted into the target product; they can be largely lost to bacterial degradation. However, when compared with other livestock production systems, aquaculture has better feed conversion efficiency and feed conversion ratios (FCRs) are continuing to improve. High levels of nutrients from fish cages may cause eutrophication and thus may affect fisheries adversely, but on the contrary, the additional nutrients from the feed may have a beneficial effect, boosting natural productivity including fisheries. The important components of fish farming waste comprise nutrients (dissolved and particulate) resulting from the metabolism of fish food, uneaten food, escapees of farmed fish affecting the genetic diversity of wild fish populations and chemical residues of disease or parasitic therapeutant treatments. Potential management measures to mitigate environmental impacts include public and private sector approaches. The public sector approaches include appropriate and specific aquaculture policies, strategies, regulations, legislation, and management plans, adoption and implementation of the FAO Code of Conduct for Responsible Fisheries (CCRF) and Ecosystem Approach to Aquaculture (EAA) strategies for planning, management, monitoring, and control. Zoning for aquaculture space is to be based on the allocation of aquafarms on suitable areas, appropriate evaluation of carrying capacity of the ecosystem, planning and management for disease prevention and treatment and environmental control. Appropriate control of farm permits, licences, and registration by the state is necessary to monitor and control aquaculture development. The private sector approaches include improved feed formulation and feeding strategies to reduce the feed conversion ratio and nutrient losses, the use of Integrated Multi-trophic Aquaculture (IMTA) to utilise nutrient outputs from intensive aquaculture and thus regular environmental monitoring is the key to ensure that impacts remain within acceptable limits.

  • Widening the Horizon of Asian Mariculture with IMTA

    • Authors: PEDRO B. BUENO
      Abstract: Integrated multi-trophic aquaculture (IMTA) expands the benefits from farming the coastal and marine waters. The benefits, achieved and enhanced by synergy among the farmed species, are environmentally sustainable, economically stable and socially acceptable. To broadly illustrate, environmental sustainability is achieved through the bio-mitigation effect of the extractive species in the mix, economic stability through product diversification and the reduction of production and market risks from such diversification, and social acceptability through environmentally and socially responsible practices. A likely outcome is better market access and price of the products enabled by the favorable attitude of consumers towards the practices of IMTA and their willingness to pay a premium price for its products. The specific benefits are described in greater detail in the review of several IMTA systems in marine and coastal environments that have been tried in a number of Asian countries, namely, China, India, Indonesia, The Philippines, Thailand and Vietnam. The challenges to their adoption are identified and policies suggested to facilitate their diffusion and adoption.

  • Brackishwater Aquaculture Health Management with Special Reference to
           Shrimp Farming in India: Status and the Way Forward

    • Authors: K. K. VIJAYAN, S. V. ALAVANDI
      Abstract: The brackishwater aquaculture in India has evolved significantly during the past four decades and has been dominated by shrimp farming. The native shrimp species have been replaced by the Pacific white shrimp. Since its introduction there has been tremendous growth in aquaculture production, contributing significantly to the economy. With the intensification and expansion of aquaculture, challenges due to disease and crop failures have become the most important concerns. The white spot disease (WSD) and Hepatopancreatic microsporidiosis or Enterocytozoon hepatopenaei (EHP) are the most important diseases causing significant economic loss to the Indian shrimp farming. Aquatic animal health management (AAHM) constitutes management practices primarily designed to prevent diseases. The AAHM at the Government level includes, import risk analysis (IRA), aquatic quarantine, disease surveillance and reporting, zoning, and contingency planning. Options at the field level on disease control and prevention are limited since these are still under research and development. The Indian brackishwater aquaculture sector has major Acts and other legal instruments in place for Coastal Aquaculture. The Indian brackishwater aquaculture has tremendous scope to increase aquatic productivity applying the principles of better management practices (BMPs) on environmental sustainability principles and make the sector economically efficient and a socially equitable enterprise, and have been adequately addressed in the recently launched Pradhan Mantri Mathsy Sampada Yojana (PMMSY).

  • Marine Ornamental Aquaculture: Measure Towards Biodiversity Conservation
           and Livelihood Promotion

    • Authors: KULDEEP K. LAL, T. T. AJITH KUMAR
      Abstract: Marine ornamental fishes are associated with the coral reef ecosystem, and they possess attractive colours, shapes, behaviours and aesthetic values. In recent days, aquarium tanks with a variety of marine ornamental organisms could be seen in homes, public places and commercial complexes, due to the developments in aquarium technologies. This indicates how this industry has been customized and became a popular hobby around the world. Aquarium business supports significant livelihood for millions of coastal and island communities across the world. Using destructive methods involving explosives and toxic substances (cyanides) for the collection of marine ornamental fishes from coral reefs damage the ecosystem and its biodiversity. Hence, aquaculture of the marine ornamentals would be encouraged as an alternative. The culture of marine ornamental fishes could be elevated from the small-scale backyard system with local coastal and island communities to big scale enterprises, by adopting feasible technologies. This article presents the overview of aquaculture of marine ornamental organisms and marine ornamental trade. The suggestions made here are intended to inform decisions on marine biodiversity conservation and livelihood promotion in coastal and island regions. Marine ornamental fisheries have been projected as an opportunity to sustainably breed marine species for the aquarium trade, while simultaneously generating employment for local communities.Â

  • Local Ecological Knowledge in Community-Based Management as Smart
           Management Options for Coastal Fisheries: A Review of the Sri Lanka
           Context

    • Authors: K.H.M. ASHOKA DEEPANANDA, UPALI S. AMARASINGHE
      Abstract: Even though small-scale fisheries throughout the globe are based on local ecological knowledge (LEK), it is often not involved in the decision-making process. An attempt is made to review the potential of using LEK of traditional coastal fisher communities in Sri Lanka and self-governing institutions in managing fisheries commons sustainably. Fisheries management in Sri Lanka is mainly a top-down system through the state legislation, while many fishing communities still maintain some level of informal or traditional management systems. The traditional community-based fisheries management (CBFM) systems in coastal fisheries of Sri Lanka, which are essentially based on LEK of fisher communities, hold long history from several decades to centuries. In active fisheries, i.e., beach seining and stilt fishing, traditional fishers accurately use LEK for day-to-day fishing activities for predicting harvests before operating the fishing gear. Long-term viability of beach seining, stilt fishing, brush park fishing, kraal fishing and stake net fishing systems in coastal fisheries of Sri Lanka confirms that CBFM systems in coastal fisheries provide better economic and livelihood standards for fisher communities. Empirical studies confirm that the coastal fisher communities manage fisheries commons through self-governing institutions through which the property rights are vested to fisher communities averting the common pool dilemma. This synthesis confirms that fishers’ LEK is an integral part of CBFM systems of coastal fisheries, which strengthen the collective action of the fishers, and is invaluable for sustaining the CBFM systems for the long run. It is clear that CBFM systems governed through robust customary institutions and evoked by traditional authority and LEK of fishers are vital for the sustainability of the coastal fisheries. In conclusion, CBFM systems and LEK can be hailed as smart management options, which can be an alternative to centralized fisheries management in Sri Lanka.

  • Feeding Ecology of Sri Lankan Blue Swimming Crab (Portunus pelagicus)
           Caught in Negombo Coastal Waters

    • Authors: H. A. C. C PERERA, S. W. WICKRAMAGE
      Abstract: The feeding habits of blue swimming crab was investigated using 250 specimens collected from bottom set gillnets in Negombo coastal waters of Sri Lanka from April to October in 2019. Out of total specimens observed, the weight range of male and female crabs was 22.45 - 334.6 g and 23.0 - 275.35 g respectively. Carapace width of crabs varied from 7.3 - 15.7 cm for males and 3.6 to 15.8 cm for females. Analysis of stomach of crabs showed 51% were empty, 25% were 25% filled, 10% were 50% filled, 5% were 75% filled and 9% were 100% filled. The main food items were mollusc remains (55.37%), arthropod parts (20.66%), fish remains (10.74%), synthetic items (23.97%), sand and debris (36.36%), algae (4.13%) and miscellaneous (35.54%). There was no significant difference of food items in terms of frequency of occurrence, percentage points and index of relative importance between sexes as well as size classes of the crab analyzed (P>0.05). It can therefore be concluded that blue swimming crabs are opportunistic omnivores with a preference for animal prey.

  • Coastal Aquaculture in Sri Lanka: Opportunities and Environmental
           Challenges

    • Authors: J.M.P.K. JAYASINGHE, UPALI S. AMARASINGHE
      Abstract: In Sri Lanka, coastal aquaculture has been a recent development which was mainly concentrated in the north-western province (NWP), and was severely affected by the outbreak of White Spot Virus (WSV) during 1990s. In the proposed Aquaculture and Culture Based Fisheries Sector Development Plan (2021-2025) of National Aquaculture Development Authority of Sri Lanka (NAQDA), under the coastal aquaculture sub-sector, the objectives set out are to increase the coastal aquaculture production from 20,000 t in 2020 to 60,000 t in 2025. To achieve the envisaged targets in coastal aquaculture and mariculture, NAQDA has planned to launch several new development projects. Conventionally, the black tiger prawn, Penaeus monodon was cultured in Sri Lanka, but recently the Pacific white shrimp Penaeus (=Litopenaeus) vannamei was introduced mainly to revive the shrimp farming sector, which has faced crop failures caused by the fatal white spot disease. Development of aquaculture of several other species such as sea bass, sea cucumber, milkfish and mud carb is also envisaged. In Sri Lanka, there is an urgent need to revise the effluent quality standards for coastal water bodies used for aquaculture. In addition to maintenance of water quality, appropriate technologies should be in place to mitigate the problems related to sediment loading. Aquaculture farmers should strive to adopt, maintain and improve better management practices (BMPs) in all aspects of farm operations. Adoption of BMPs during site selection, pond construction and preparation, selection of post larvae for stocking, bottom sediment management and disease management may also reduce the risk of the impacts due to climate change.

  • Emerging Information and Communication Technologies for Monitoring
           India’s Marine Small-Scale Fisheries, Opportunities for Inclusion,
           Risks of Exclusion

    • Authors: ALEXANDER TILLEY, ANDREW M. SONG, AJIT MENON, PHILIPPA J. COHEN, MARIANNE MANUEL
      Abstract: Adaptive, inclusive and effective management of fisheries resources is dependent on knowledge from multiple quantitative and qualitative sources. As technology advances, there is an increasing interest in digital and automated solutions for gathering fisheries data. Small-scale fisheries (SSF) have presented a persistent challenge to many centralized quantitative data collection systems, and frequently maintain the status of ‘unreported’. This unreported nature often implicates SSF in the definition and discussions of illegal, unreported and unregulated (IUU) fishing. Monitoring, control and surveillance are seen as a vital part of the solution to IUU fishing, with substantial investment being put into increasingly sophisticated technology for tracking fishing vessels. For the past few years, India has been attempting to pass legislation to require all vessels, from small-scale to industrial, to install vessel monitoring systems on the grounds of national security and combating IUU fishing. However, there are concerns that a securitized and top-down approach to implement vessel tracking is not only wasteful but risks further marginalization of small-scale fishers from the resource, and fisheries groups from governance processes. India should seek to solve the underlying causes of IUU fishing while also developing collaborative monitoring and community-based management models. In this paper, we review evidence of emerging information and communication technologies and approaches in SSF and discuss how, if introduced and managed through collaborative processes, they could be used as a platform to strengthen inclusive governance, increase sustainability and improve wellbeing in coastal fisheries in India.

  • Fisheries Cooperatives as a Platform to Address Multi-stakeholder Issues
           in South Sri Lanka: Incorporating SSF Voluntary Guidelines into the ICZM
           Process

    • Authors: OSCAR AMARASINGHE, K. H. K. L. PIYASIRI
      Abstract: Coastal resources are used by multiple stakeholders with diverse interests, whose actions often give rise to conflicts, showing the need for integrated coastal management where resource use decisions are made with the participation of all. While all relevant state actors operate along the coastal belt, there hardly exists any coordination among them, revealing the absence of integrated efforts in coastal resource management. This study was undertaken in this context, aiming at finding out the potential lead role, a community based organisation could play in initiating an integrated coastal management platform. Since the recently developed SSF Guidelines have important implications for such a platform, the study examined the extent to which fisheries cooperatives qualify for such a task. Rekawa of Southern Sri Lanka was selected for the study. The methodology involved a Focus Group Discussion with representatives of all coastal resource users, and a questionnaire survey. Results revealed that, conflicts among stakeholders were pervasive but remained latent. They have been resolved mainly through private negotiations. Among the three community organisations in operation, the marine fisheries cooperative ranked first in respect of providing livelihood capitals and, in its potential to adopt key concerns highlighted in SSF guidelines, but ranked low in resource management. Holistic, integrated, inclusive approaches to management with the participation of all relevant parties and, improving the socio-economic conditions, were accredited as the most pertinent SSF guidelines towards conflict resolution. The study showed that fisheries cooperatives could play an important role in the process of integrated coastal zone management, providing a formidable platform to address multiple stakeholder issues.

  • Trophic Relationships and Structure of Brackish Water and Coastal
           Ecosystems: Possible Common Trends between African and Asian Waterbodies

    • Authors: JACQUES MOREAU, S.S.K. HAPUTHANTRI, PHILIPPE LALEYE, ALLASSANE OUATTARA, N.T. PHUONG
      Abstract: In the present synthesis, trophic relationships of eight coastal and brackish ecosystems in some countries of Africa and Asia were reviewed (Ivory Coast, Benin, Senegal, in Africa, Sri Lanka, Vietnam, Thailand and China in Asia). For these highly productive and complex ecosystems, knowledge on the biological and ecological functioning of fish faunas utilizing, as well as, the environmental forces contributing to geographic specificities of these environments is vital for their sustainable management and conservation. Recognizing that anthropogenic activities impact not only the environment but the dynamics and functioning of its living resources, untangling ecosystem processes can increase understanding of its current health and resilience to change. Effective management of these ecosystems should focus on a framework based on a sound understanding of ecosystem

  • Threats to Fish Biodiversity in Bangladesh Waters and Measures for Revival
           of Declining Population

    • Authors: M. J. RAHMAN, M. NAHIDUZZAMAN, M. A. WAHAB
      Abstract: Bangladesh is rich in fish biodiversity covering interconnected riverine, coastal and marine habitats. Many researchers reported different potentials and threats of biodiversity and suggested measures to minimize the threats. Revival story of hilsa and relevant fish population revealed hopes and ways of sustainable biodiversity management. We attempted to compile the fragmentary fish biodiversity information, described the revival story of hilsa and other important fish along with the threats and challenges of the fish biodiversity and suggested measures for the sustainable management of the fish biodiversity. Freshwater habitats are rich in biodiversity with 265 fresh water fish species. The Meghna River supports the highest 200 fish species as a single river. The marine habitat covers an area of 118,813 km2 that produces 0.66 million tons of fish annually and owned 475 species in 1971, but recent exploration suggests the existence of 394 species. However, the species diversities are increasingly facing threats from direct and indirect anthropogenic activities including juvenile catch, overexploitation, creating obstructions in the migratory routes, pollutions and climate change. Hilsa, the most important species also severely faced these threats and as a result, the production declined to below 0.20 million tons in 2002-2003. Joint efforts of all stakeholders through incentive based co-management led to the hilsa fishery revival, and its production reached 0.533 million tons in 2019. Along with the hilsa, other interdependent species, especially four important catfish species (Pangasius pangasius, Sperata aor, Bagarius bagarius and Rita rita) have also revived remarkably. Following the lessons learned from the revival of fishery, several management measures focusing on juvenile conservation, protection of broodstock, harmful gear elimination, optimum exploitation, pollution control, incentive-based co-management, habitat protection, restoration and rehabilitation are suggested to ensure maximum sustainable productions and biodiversity conservation focusing on vulnerable and threatened species and improved livelihoods resilience of fishers through good governance.Â

  • By-catch from the Artisanal Shrimp Trawl Fishery off Negombo, Sri Lanka

    • Authors: E. M. M. I. EKANAYAKA, P. D. S. MADHUSHANKHA, D. C. T. DISSANAYAKE
      Abstract: By-catch is one of the serious problems in shrimp trawling. This study analyzes the by-catch of a well-established traditional shrimp trawl fishery that exists in the coastal waters off Negombo, Sri Lanka. Catch, effort data and by-catch samples were collected by making fortnight field visits to the trawl landing site at Negombo from January to December 2019. The total catch (kg) and CPUE (kg hr-1) of shrimp and by-catch, shrimp to by-catch ratio, composition of by-catch and its economic benefits were assessed. By-catch reported lower CPUE values (1.3±0.5 kg hr-1) than shrimp (2.6±0.8 kg hr-1) throughout the study period except in April and July. The estimated shrimp to by-catch ratio in this traditional trawl fishery is 1:0.52. By-catch represents 51 fish species from 17 families, 3 crab species, 2 species of rays and 3 cephalopod species. The total annual by-catch was estimated at 25.55 Mt, which comprised 80% fish, 10% crabs, 3% rays and 7% of other invertebrates. Species belonging to the family Sciaenidae made the highest percentage contribution (26.04%) to the total by-catch followed by Cynoglossidae (15.87%), Clupeidae (11.18%), Pristigasteridae (10.7%) and Leiognathidae (10.51%). By-catch provides livelihoods for fifteen women fish vendors in this area, generating an average daily income of ~1, 069.00 LKR and also makes 8% contribution to the average daily income of a shrimp trawl (~3, 940.00 LKR). There were no reported discards in this fishery. The findings of this study will be useful in updating existing information and defining measures to manage and better utilize by catch in this small-scale fishery.

  • Dwindling Coastal Fisheries Biodiversity of Bangladesh: The Causes and
           Effects

    • Authors: MOSTAFA A. R. HOSSAIN, MOHAMMAD R. HASAN
      Abstract: Being a sub-tropical nation in the Ganges-Brahmaputra-Meghna (GBM) Delta with long shoreline along the Bay of Bengal, the coast of Bangladesh is blessed with rich living resources. The country has a coastline of about 710 km and an Exclusive Economic Zone of 121,110 km2. Bangladesh’s coastline extends from St. Martin’s living coral island in the south-east to the Sundarbans-world’s largest adjoining mangrove-in the south-west. The coast holds diverse habitats- coral, sandy, muddy and rocky beaches, salt marshes, grass beds and mangroves - with uniquely diversified faunal configurations. So far, 730 fishes, 150 crustaceans and 336 mollusks have been recorded from the coastal waters of Bangladesh, apart from a number of cephalopods, sea turtles, reptiles, and mammals. Increasing population, destruction of mangroves, pollution, overfishing, and illegal/destructive fishing using set bag nets and monofilament gillnets and an extensive collection of shrimp larvae are the root causes of biodiversity loss in the coast. Already, the near-shore fish stocks are overexploited and catch per unit fishing effort is falling and many shrimp and fish stocks are in the decline. The percentage contribution of marine segment in the fisheries sector of the country is decreasing every year. About 28% of the coastal fishes assessed by IUCN (International Union of Conservation of Nature) are now placed under IUCN Red List of ‘threatened species’. To ensure sustainable fisheries management, a number of laws have been put in place, but the implementation of these laws and regulations is constrained due to conflicts and non-compliance by the stakeholders. Hence, Bangladesh needs a robust legal and policy framework for conservation and sustainable utilization of the coastal resources. Establishment of sanctuaries and marine protected areas following a co-management approach can achieve notable success in protecting coastal biodiversity. Strict enforcement of legal measures aimed at protection of mangroves, development of eco-coastal tourism and social safeguards for resource conservation and management, is needed for long-term and sustainable management of coastal biodiversity of Bangladesh.

  • Indo-Sri Lanka Fishing Conflict in the Palk Bay and its Implications for
           Fisheries

    • Authors: K. H. M. L. AMARALAL, N. ABEYKOON, K. H. M. ASHOKA DEEPANANDA
      Abstract: The Palk Bay constitutes exceptionally rich fishing grounds for the fishers of India and Sri Lanka. In the recent past, dispute between Indian and Sri Lankan fishers has emerged in exploiting fisheries resources, posing serious threats to the livelihoods of thousands of fishery dependents in the two countries. Present study comprehensively explores all aspects of Indo-Sri Lanka fishing conflict, reviewing articles published during 1995-2018. Twenty-five articles that addressed the Palk Bay fishing conflict were obtained, using a systematic search strategy. The present study unfolds that fishers were engaged in fishing activities in Palk Bay, using different craft and gear combinations over many decades. Conspicuously, several factors are influential for the emergence and escalation of Indo-Sri Lanka fishing conflict, including; (1) establishment of International Maritime Boundary Line (IMBL); (2) introduction of mechanized trawls by Indian fishers in 1960s with the expansion of the export market demand for shrimp; (3) imposition of fishing ban by Sri Lankan government during civil war during 1983-2009; (4) recommencement of distant water fisheries in the Palk Bay by Sri Lankan fishers with the conclusion of civil war in 2009, and (5) damage to fishing crafts and gears of artisanal fishers. Moreover, the study elucidates that Indo-Sri Lanka fishing conflict has a detrimental impact on the fisheries industry, livelihoods of the fishers, economy and political stability of India and Sri Lanka. Furthermore, the fishing conflict has caused many negative impacts including depletion of fishery resources, increase in enforcement cost, reduction of foreign exchange earnings, arresting fishers, presence of illegal trading and smuggling of arms and ammunition. Several measures have been taken by Indian and Sri Lankan Governments to resolve the fishing conflict. Albeit, they have yet to come to a common agreement to find an amicable long-lasting solution, vital for moving forward the industry in a sustainable manner.
