  • Production and marketing practices of mangrove crab industry towards
           sustainability in Bataan, Philippines

    • Authors: Madel Fernandez DAMASO
      Abstract: This showed a comprehensive study on the mangrove crab industry in Bataan, Philippines. Mangrove crab growers (35%) were between 51-60 years old, mostly married with 5-7 family members. Farming was highest (30.77%) between 6-10 years while some were farming for 40 years (1.29%). Monthly income has strong positive correlation (r=676) with production area. Scylla serrata, S. olivacea, and S. tranquebarica were identified using traditional ecological knowledge (TEK). Results revealed 69.57% of the pond used for farming was 1-10 ha employing the polyculture method. About 52.17% used coin-sized crablets while 39.13% fly-sized. Annual production was less than a ton for 46.38% growers while 1.45% have >5 tons. Annual income showed a strong positive correlation (r=0.886 and r=0.815) with production area and annual production, showing a significant difference (p<001). Harvested crabs were marketed live in Orani Port. Grading and pricing were due to sex, weight, and characteristics. Problems include the implementation of FAO 264 s. 2020, weather, market practice, pandemic, and high rejections. Men and women play significant roles where laborious were perceived to be men’s sphere while less laborious and financial aspects were for women.

  • A preliminary life history traits analysis of sharks in the Sea of Marmara
           (Türkiye), where deoxygenation and habitat deterioration are raising

    • Authors: Hakan KABASAKAL; Serdar SAKINAN, Lovrenc LIPEJ, Danijel IVAJNŠIČ
      Abstract: Life history traits of 17 species of sharks occurring in the Sea of Marmara were analysed based on Gower’s distances, Principal Coordinate Analyses, and hierarchical clustering. The analysis shows that the sharks of the Sea of Marmara can ecologically be divided into several clusters. The increasing occurrence of sharks on the Marmara continental shelf, especially in the last few years, suggests that the expected habitat compression due to deoxygenation has begun to take place. This situation, which can be considered as a “habitat trap” for sharks, should be considered as a threat that may lead to shark mortalities due to the intensification of bycatches or even the intentional killing of sharks. Available results are sufficient to predict a disturbing future for sharks of the Sea of Marmara if the factors (deoxygenation, habitat loss, bycatch, etc.) threatening the overall ecosystem do not improve.

  • Investigation of fatty acid profiles in some economically important fish
           species living in Atatürk Dam Lake, Adıyaman, Türkiye

    • Authors: Yasin YAKAR; Arif PARMAKSIZ, Muhammed Yaşar DÖRTBUDAK, Necmettin DOĞAN
      Abstract: This study aims to determine the fatty acid profile of 10 fish species (Carassius gibelio (Bloch, 1782), Chondrostoma regium (Heckel, 1843), Cyprinus carpio (Linnaeus, 1758), Carassius auratus (Linnaeus, 1758), Alburnus sellal (Heckel, 1843), Planiliza abu (Heckel, 1843), Capoeta trutta (Heckel, 1843), Arabibarbus grypus (Heckel, 1843), Mastacembelus mastacembelus (Banks & Solander 1794) ) caught from Atatürk Dam Lake, sold by fishermen and consumed by local people. Accordingly, the fish species identification was made and the individuals belonging to the determined species were randomly selected and muscle tissue was taken from each sample for fatty acid analysis and put into tubes. Extraction of fats from muscle tissue was carried out using a chloroform-methanol solvent mixture. The methylation process of fatty acids was carried out using the TS EN ISO 12966:2 method. Analyzes were performed with Thermo brand Trace GC model GC with FID (Flame Ion Detector) detector. A 60 m HP-88 column was used in the analysis. It has been determined that 10 fish species contain a total of 26 different fatty acids. Palmitic acid is the major fatty acid among saturated fatty acids (SFA). Palmitic acid values vary between 18.31 % and 25.51 %. It was determined the most in C. carpio and the lowest in C. auratus. Among the mono unsaturated fatty acids (MUFA), oleic acid is the major fatty acid and was found between 12.70 % and 29.77 %. It was detected at most in A. sellal with a rate of 29.77 % and in P. abu with a minimum rate of 12.70 %. Of the polyunsaturated fatty acids (PUFA), docosahexaenoic acid is seen as the major fatty acid. It was detected at most in C. trutta with a rate of 14.24 %, and at a minimum in C. carpio with a rate of 0.62 %.

  • Effects of the fresh and dried housefly (Musca domestica) larvae in the
           diets of Nile tilapia Oreochromis niloticus (Linnaeus, 1758): growth, feed
           utilization efficiency, body composition and biological indices

    • Authors: Cayen Sédro ALOFA; Isabella Yasmine OLODO, Mouhamed CHABI KPERA OROU NARI, Youssouf ABOU
      Abstract: A 56-day feeding trial was undertaken to assess the effects of housefly maggots (HM) forms (dried and fresh) as protein sources on growth, feed efficiency, and body indices of Oreochromis niloticus fingerlings. A control diet (T0) contained 300 g/kg of fishmeal (without HM). Two practical diets with the same formula were prepared with dried HM (T1) and fresh HM (T2) where 66 % of the fishmeal was replaced. Diets were fed to triplicate groups of tilapia (mean initial weight: 10.26 ±0.12 g). There was no difference in survival, condition factor, feed conversion ratio, and protein efficiency ratio. Fish fed diets T0 and T1 had significantly increased (P < 0.05) mean final weight (50.25 ±1.39 - 52.24 ±1.03 g), specific growth rate (2.84 ±0.03 - 2.88 ±0.03 %/day) and weight gain (389.70 ±7.63 - 402.78 ±8.16 %) compared to T2 diet ones (46.30 ±2.03 g; 2.67 ±0.07 %/day and 356.70 ±7.76 % respectively). Viscerosomatic and hepatosomatic index in fish fed T1 and T2 diets were significantly higher than those fed T0. The present findings indicate that the dried form of housefly maggot has given the best results in terms of growth compared to the live form. However, housefly forms did not affect feed efficiency parameters.

  • Mitochondrial DNA sequence analysis of Arabibarbus grypus (Heckel, 1843)
           living in Great Zab (Erbil, Iraq)

    • Authors: Arif PARMAKSIZ
      Abstract: Arabibarbus grypus (Heckel, 1843), which naturally lives in the Euphrates and Tigris River systems and is endemic, is an economically important fish species consumed by humans. Since the population of this species, which is hunted by both fishermen and local people, is decreasing day by day, its genetic characteristics need to be determined. This study aims to determine the genetic characteristics of A. grypus samples living in Great Zab based on sequence analysis of mtDNA cyt b and mtDNA d loop gene regions. Total DNA isolation was performed from muscle tissue using the kit. Then, Polymerase Chain Reaction was applied through specific primers to mtDNA cyt b and mtDNA d loop gene regions, and the target regions were amplified. The products with the target length were sent to the commercial firm and sequence analysis was performed. Regarding these specimens living in Great Zab, two haplotypes were determined for the mtDNA cyt b gene region and five haplotypes for the mtDNA d loop gene region. These haplotypes were compared with the haplotypes in the gene bank and the results were evaluated. Some important data has been obtained regarding the conservation and management of this fish species. Since three new haplotypes were detected for the d loop region in this studied locality, it is important to include the samples in this locality in conservation studies.

  • Investigation of different lighting (LED, HPS and FLO) in aquaponics
           systems for joint production of different plants (Lettuce, Parsley and
           Cress) and koi carp

    • Authors: Devrim MEMİŞ; Gökhan TUNÇELLİ, Merve TINKIR, Mehmet Hakan ERK
      Abstract: We investigated the effects of growth performance of three plant species parsley (Petroselinum crispum), lettuce (Lactuca sativa) and cress (Lepidium sativum) under the three different lighting sources, Light-Emitting Diode lamp (LED; 200w), High-Pressure Sodium lamp (HPS; 200w) and Fluorescent lamp (FLO; 200w) in an aquaponic system. A total number of 43 koi fish (Cyprinus carpio var. koi) with 3628 g total biomass (84.4 g per individual) were used. The fish used in the experiment recorded 36% growth and reached an average individual weight of 132.7 g at the end of the experiment. The parsley plant was measured as 8.76 ±7.32 g; 7.45 ±4.13 g; 2.04 ±1.96 g weight after 45 days, the lettuce plant was 54.09 ±25.60 g; 60.83 ±19.39 g; 17.81 ±6.40 g weight after 54 days, cress plant was 1.03 ±0.58 g; 1.15 ±0.46 g; 1.31 ±0.58 g weight after 42 days, under the HPS, LED, and FLO light sources, respectively. HPS and LED light sources in lettuce and parsley showed better plant development than the FLO, while no significant difference occurred in cress plants under three light conditions. We conclude that using HPS or LED lights in indoor aquaponics has the potential to produce good quality and adequate amounts of plants.

  • Investigation of the effects of some environmental variables on the
           zoobenthic community structure: The case of Porsuk Stream (Sakarya River,

    • Authors: Deniz MERCAN
      Abstract: In order to examine the effects of some physicochemical parameters on the zoobenthic community structure in Porsuk Stream, seasonal zoobenthic samples were collected from 6 stations between 2020-2021, and some physicochemical parameters were also measured. Within the scope of the study, a total of 30 families, 4 from the Gastropoda, 1 from the Bivalvia, 3 from the Clitellata, and 22 from the Insecta, were identified. Families Tubificidae, Erpobdellidae, and Chironomidae were identified at each station. Dominant groups in Porsuk Stream zoobenthos; Tubificidae (41.90 %), Chironomidae (16.68 %), Gammaridae (7.84), Valvatidae (6.16 %), Naididae (5.30 %), Asellidae (3.73 %), Physidae (% 3.48 %), Dreissenidae (3.16 %), Baetidae (3.07 %), Simuliidae (1.70 %), Erpobdellidae (1.69%) and Lymnaeidae (1.32 %), respectively. The highest dissolved oxygen value was measured in the Sobran Stream with an average of 11.3 mg/L. Detection of Caenidae from Ephemeroptera and Hydropsychidae from Trichoptera with low tolerance to pollution and results of the Canonical Correspondence Analysis in this station shows that dissolved oxygen concentration is effective on the distribution of taxa determined in the basin. At the same time, this station has the highest BMWP (64) and Shannon (2.22) values.

  • New record of the prickly shark Echinorhinus cookei (Pietschmann, 1928)
           and evidence of scavenging by the coyote Canis latrans (Say, 1823) in
           Bahia de Los Angeles, Baja California, Mexico

      Abstract: Echinorhinus cookei is a rare, large, demersal, deep-sea species of shark inhabitant of the Pacific Ocean basin. A sub-adult female with a total length of 262.7 cm was found naturally stranded in 2021 at Bahia de Los Angeles, Baja California, Central Gulf of California. It presents two spineless dorsal fins closer to the pelvic fins, large star-shaped dermal denticles, and distally oriented multi-cusplet cutting-type teeth. Along the shark, a peninsular coyote Canis latrans peninsulae was observed scavenging on the shark carcass. This study documents the first record of E. cookei in the Bahia de Los Angeles area and the first record of scavenging by the coyote C. latrans on any echinorhiniform shark to date.
