Abstract


Rajungan merupakan hasil komoditi perikanan yang memiliki nilai jual yang sangat tinggi, baik sebagai komoditi lokal maupun komoditi ekspor. Desa Betahwalang, Kabupaten Demak, Jawa Tengah merupakan pusat pendaratan rajungan dari berbagai wilayah. Penelitian ini bertujuan untuk mengestimasi biomassa, Maximum Sustainable Yield (MSY) dan pemanfaatan nilai ekonomi rajungan level MSY di Kabupaten Demak. Metode yang digunakan adalah metode swept area untuk menentukan biomassa dari rajungan dan wawancara dengan nelayan arad untuk menentukan pemanfaatan nilai ekonomi. Pengumpulan data MSY diperoleh dari 6 kali trip penangkapan dan pengumpulan data pemanfaatan nilai ekonomi diperoleh dari wawancara terhadap 30 nelayan arad. Hasil penelitian menunjukkan bahwa biomassa dan MSY rajungan di Desa Betahwalang masing-masing yaitu 23,5 ton dengan nilai ekonomi sebesar Rp. 305.141.586/tahun.

Blue swimming crab is a commodity that has a very high price value, both as local and export commodities of fisheries. Betahwalang Village located in Demak, Central Java, is the center of the blue swimming crab fishery landings of various regions. The purposes of this study are to estimate the biomass, Maximum Sustainable Yield (MSY) and the utilization of the economic value of MSY level blue swimming crab in Demak. The methods of research were swept area method to determine of blue swimming crab biomass and interview with mini trawl fishermen for the utilization of the economic value. MSY collecting data got by 6 trips of small crab fishing and utilization of the economic value collecting data got by interview with 30 mini trawl fishermen. The results showed that biomass and MSY were 23,5 tons and utilization of economic value was Rp. 305.141.586/year. It was that Demak waters have experienced fully exploited.
