DISTRIBUSI UKURAN IKAN TERI (Stolephorus sp) YANG DITANGKAP PADA PERIKANAN BAGAN TANCAP DI MUARA SUNGSANG SUMATERA SELATAN (Size Distribution of Anchovy (Stolephorus sp.) Caught in Stationary Liftnets at Sungsang Estuary South Sumatera)
Get PDFABSTRACT The anchovy (Stolephorus sp.) in Muara Sungsang estuary South Sumatera are generally caught by stationary liftnet. Morphometric studies are essential to determine the growth form and growth rate of species, which is very much important for proper utilization and management of the population of the species. This study aimed to determine the size structure and growth pattern of the anchovy caught by stationary liftnet. The size structure, length -weight relationship and the condition factor of anchovy were computed. The anchovy samples were taken in July 2013 (750 samples) and September 2013 (1950 samples). Results showed that the population of anchovy was dominated by length frequency distribution of 65 mm during study on July 2013 and 75 mm during study on September 2013. Both populations were dominated by weight frequency distribution 2 gram. The anchovy that caught on September 2013 were more allowable catch than on July 2013. The growth pattern of anchovy was negative allometric. The relative condition factor (Kn) value in September 2013 was higher than in July 2013. It indicated that the environmental conditions at Muara Sungsang estuary are suitable for growth of anchovy’s and still safe from fishing pressure.Keywords: allometric, anchovy, condition factor, frequency distribution ABSTRAKIkan Teri (Stolephorus sp.) di Muara Sungsang Sumatera Selatan umumnya ditangkap menggunakan bagan tancap.

MODEL BIOEKONOMI EKSPLOITASI MULTISPESIES SUMBER DAYA PERIKANAN PELAGIS DI PERAIRAN SELAT BALI (Bio-economic Model of Multispecies Exploitation of Pelagic Fishery Resources in the Bali Strait)
Get PDFBali Strait has potential abundance of pelagic fishery resources such as Indonesian oil sardine (lemuru), frigate mackerel (tongkol), scad mackerel (layang), short-bodied mackerel (kembung) and others which can be caught mostly using purse seine. Fishery resources are combined and also known asmultispecies; therefore this research aimed to analyze the model of bio-economic multispecies exploitation of pelagic fishery resources in Bali Strait. The analytical methods that used in this research were estimated dynamic model of Walters and Hilborn (1976) and analysis of bio-economic model. The results showed that actual production of exploitation of pelagic fishery resources in Bali Strait, was lower than the rate of sustainable production especially Indonesian oil sardine and short-bodied mackerel. Production and fishing effort were below the actual optimal value. The management of pelagic fishery resources in Bali Strait did not show a good level of economic efficiency. Thus the exploitation of pelagic fishery resources in Bali Strait using purse seine could still be increased.Key words: bio-economic, multispecies, optima
KELEMBAGAAN PENGELOLAAN SUMBER DAYA PERIKANAN TANGKAP BERBASIS RESOLUSI KONFLIK DI KALIMANTAN SELATAN (Institutional of Capture Fishery Resources Management Based on Conflict Resolution in South Kalimantan)
Get PDFManagement of fishery resources can be hampered by destructive conflict. A fairly long period of conflict, due to the institutional implications of conflict management is not effective, therefore this studyaimed to 1) map the institutional management of fishery resources, 2) reveal on the role of institutional management of fishery resources management, 3) develop a concept institutional management of capture fisheries. This study used a qualitative descriptive approach and was analyzed in narrative. The result showed that the institutions that played role in conflict management consisted of formal, non formal and community institution of traditional societies. Institutions were in a synergy in community based monitoring system of fisheries and marine resources - which consisted of society groups and have a network ranging from district to central government levels. They played a role in making operational policy for supervising and controlling fishery resources, coordinating and harmonizing the programs and activities among institutions, as well as taking actions to follow up the allegations based on the information from society groups.. Conflict resolution can be done effectively with the negotiation and facilitation techniques known as ADR (Alternative Dispute Resolution). Thus, conflict management was conducted cooperatively by prioritizing on acceptable and long term output. . Application of ADR was conducted by involving the whole of law functionaries. Its application was believed could smooth the various institutional functions.Key words: capture fisheries, conflict, institutions, management, resolutio
