Abstract

Squid net is one of alternatives to replace trawl net in Pati regency. The purposes of the research are 1) to determine the influence factors, 2) to analyze the return to scale, 3) to analyze cost and return.The research location in Juwana Subdistrict particularly Bakaran Kulon, Dukutalit, Bajomulyo and Bendar Villages. The research conducted on October 2015 to June 2016. The number of final samples was 36, while the formulation of management strategies used 15 samples by snowball sampling. Data analysis techniques used 1) Cobb Douglas production function, 2) revenue-cost ratio analysis. The results of the research are 1) significant inputs for production factor are long trip, Solar fuel, the number of crew and lights. 2) the return to scale of squid net bussiness in Juwana subdistrict Pati regency is -0.231 means decreasing to scale. 3) the R/C ratio of scenario II more profitable for squid net crews than  scenario I.

Abstract

Pelagic fish was the main raw material for fish processing industry. Rate of fishing that not equivalent with the growth of fish resources, eventually will decrease the catch of fishermen. Aims of the research were (1) to estimate the bioeconomic of pelagic fish resources on MSY (Maximum Sustainable Yield), MEY (Maximum Economic Yield) and OA (open Access) conditions; (2) to estimate the optimum utilization rate, (3) arrange the management model of sustainability pelagic fish resources in Pati regency. This research was descriptive quantitative and conducted in March until September 2017. Reseacrh location in Bajomulyo village and Bendar village Juwana Subdistrict with 35 samples. Data analysis : (1) gear standardization, (2) bioeconomic static optimation model approach, (3) bioeconomic dinamic optimation model approach, (4) reconstruction of in-depth interview results. Result of the research are (1) bioeconomic static optimation model approach namely, biomass MEY>MSY>OA, catch MSY>MEY>OA, effort OA>MSY>MEY, profit MEY>MSY>OA; (2) bioeconomic dinamic optimation model approach namely, biomass MEY>MSY>OSY>OA, catch MSY>MEY>OSY>OA, effort OA>MSY>OSY>MEY, profit MEY>>OSY>MSY>OA; (3) pelagic fish management model are input controlling, output controlling and technical provisions.
