  • MOLTING AND SPAWNING SYNCHRONY IN Marsupenaeus japonicus FROM TOKYO BAY

    • Authors: Agung Setiarto
      Pages: 75 - 84
      Abstract: This study was the first attempt to examine the molt stage and molting cycle in relation to the ovarian development of M japonicus in Tokyo Bay In particular the study was done to reveal molting and spawning relationship, to predict reproductive peaks and thus larval recruitment and to investigate the possibility of multiple spawning within one molt cycle in natural condition, Ohh: three out of five stages were represented in the samples since the early premalt (A) and ecdysis (E) occured in a very short time. There occured was a co-occurrence between ovarian maturation and molt stage, in which maturing ovaries occurred at B (late postmolt) to D, (earlv premolt) stage, mature ovaries at C (intermold to D; (late premoly, and spent ovaries at D, to D,. Molting and spawning synchronization was observed in kuruma prawn, in which molting fequency was highest prior to and at the end of spawning season. There was a possibility of multiple spawning within single molt cycle in wild kuruma prawn, since there were enough time for spent ovaries to redevelop into mature ones.

  • THE INDONESIAN CORAL REEF REHABILITATION AND MANAGEMENT PROGRAM: LESSONS
           LEARNED IN COMMUNITY-BASED REEF MANAGEMENT ` AT SENAYANG AND LINGGA
           ISLANDS, RIAU

    • Authors: Dirhamsyah .
      Pages: 85 - 96
      Abstract: The Coral Red Rehabilitation and Management Program (COREMAP) is a I5-year program of the Government of Indonesia. It has been working at several sites in Indonesia since /998 to achieve sustainable use of coral reefs through the delegation of management authority to local communities. The establishment of epective models for participatory and community-based management is the core of this program. The model for community-based management includes community participation. community capacity building, promotion of alternative income generation, establishment of coral red management plans, community marine sanctuaries and community red watcher programs. This paper describes the experiences and lessons learned in Phase I of the COREMAP Project in implementing community—based red management at Senavang and Lingga Islands, Riau Province. It is argued that the involvement ofthe community in the planning and implementation process of coral reef management will improve the management and conservation of coral req' ecosystems. It is hoped that the Indonesian experience will contribute to the comparative literature on coral req' management.

  • THE INITIAL ADSORPTION OF Pb2+ TO Dunaliella salina

    • Authors: Moh. Muhaemin
      Pages: 97 - 105
      Abstract: The adsorption process of metal ion to algal sudace groups and complexes to become organic material at all growth phases could be ajecting their behaviour in seawater. The dwerential pulse anodic stripping voltammetry (DPASIO method was used to determine the adsorption and interaction between the Dunaliella salina and Pbz`. The rate of adsorption was found in two steps; first a relative fast adsorption step (I0 min) and second slower or aw'usion—controlled uptake into the cells. The parabolic equation could be performed ([Pb2+]mr,a = L3 I x I0'7 + 0.062 x 107 V0 to describe the relationship between metal ion adsorption and uptake by the algae as a function of time. The high ajfinity constant is similar to the complexing capacity by the alga and no signylcant effect of cell density on binding capacity. This shows that ligands produced by the algae play an important part in buffering concentration of free metal concentration

  • THE ANTIOXIDANT CAROTENOID CONSTITUENT FROM MARINE MACRO ALGAE

    • Authors: Ifah Munyah, Th. Dwi Suryaningrum, Heni Krisnawang
      Pages: 107 - 118
      Abstract: Most of the potentially harmful ejiects for the human body is hee radicals. A fee radical is any chemical species that has one or more unpaired electrons. Many fee radicals are unstable and highbz reactive. ~l-larmjtl %cts of jree radicals for the human body are their chemical reactivity can damage all types of cellular macromolecules and the chain qfects. Nutrition plays a key role in maintaining the body's enzymatic d%nses against fee radicals. It is believed to play an important role in cellular defenses against oxidative damage. Our work on new bioactive compounds hom marine macro algae has led to the isolation, characterization, and antioxidant assays of semi polar extract fom 5 d@rent macro algae (2 green algae and 3 brown algae) and structure elucidation. By using a in vitro antioxidant assays DPPH radical scavenging (I, I- dtphenyl-2·pici3¤llgzdrazy2D, the etil acetate extract of macro algae was separated by sephadex C-8 with eluent EtOAc/MeOH the faction analyzed through LCMS 20l0A.These studies of marine macro algae ojkred important new insight that the chlorophyll factions jiom brown algae have better inhibition activity against fee radicals than green algae did

  • PRODUCTIVITY OF TROPICAL LIMPET Cellana testudinaria ` (Linnaeus, 1758)
           LIVING ON THE ROCKY SHORE OF OHOIWAIT, SOUTHEAST MOLUCCAS, INDONESIA

    • Authors: Abraham .
      Pages: 119 - 130
      Abstract: Study on the productivity of tropical limpet C testudinaria has been carried out at approximatelv monthly intervals fom October 200] to September 2002. A total of 2404 limpets of 8.2 - 3],8 mm in size were obtained in ]2 month collections. The size structure of population presented 6 cohorts with accounting for 48% ofthe second cohort ofthe total population, The mean annual population biomass was estimated to be IOI3 1 748 mg AF DWm'2 or 2].8 kim`), hence the annual population production estimated by the mass specific growth rate method to be 2.8] gr.m`Z or 60. 7 K.Lm`2.yr". The annual biomass turnover ratio Qzroduction to biomass ratio, P/B) was 2. 77 yr". This value ofthe P/B ratio is higher than those obtained for other limpet species living 2 to 5 years reported by other researchers due to the diferentkaturing of growth parameters such as K = l.4 yr" and L., = 33.08 mm resulted for C. testudinaria.

  • A DEVELOPMENT PLAN FOR TOURISM POTENTIALS IN COASTAL AREA OF UJUNGNEGORO,
           BATANG REGENCY

    • Authors: Suzzana Ratih Sari, Edy Darmawan
      Pages: 65 - 74
      Abstract: Ujungnegoro is one coastal area in Batang Regency Central Java, which offers a unique environmentalsetting as well as enormous tourism potentials such as marine resources, aquaculture and plantations.Furthermore, Ujungnegoro has a variety of terrain ranging from plain to hills. Despite these potentials,presently the government faces some problems which hinder the development of tourism in this area,namely limited capital for development purposes, absence of infrastructure, inadequate governmentassistance in terms of budgeting and technical assistance. This paper analyzes these problems andidentifies appropriate planning strategies that may be adopted to promote the tourism industry inUjungnegoro, Batang Regency. These strategies will hopefully evolve into policies that will develop thisarea into uppropriate tourist destination. Should this come to pass, this area will provide a greatercontribution to the development of the area as a whole.
