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.

Thus, the Pati regency is one of the areas in presence of pelagic fish stock is very Central Java Province that supports the important for the sustainability of the fishery marine fisheries production in Central Java. processing industry. In 2015, the production of Pati regency was Utilization of pelagic fish for the ranked in second place compared to 2014 processing industry causes fishermen try to with 16.21% contribution. Rembang regency maximize the catch. The way taken is to was the largest contributor of marine increase the capture effort in the hope of fisheries in Central Java with 20.48%, third obtaining maximum results. However, if the place was Batang regency with 8.61%. The rate of fishing not equivalent with the other areas that contribute to marine growth of fish resources, fish stocks will fisheries, among others Pemalang regency decrease and eventually lead to a decrease in 8.44% and Cilacap regency 4.42% (Central the catch of fishermen.

The largest type of catch is stocks to decline and do not have the Decapterus russelli. Decapterus russelli is opportunity to breed. This is stated by one of the small pelagic fish species. The Nikijuluw (2002) that the overfishing status increase in catch percentage from 2014 to of fish resources in a waters is basically 2015 amounted to 422.70%. In 2016, catches related to the intensity or frequency of of Decapterus russelli decreased by 48.20%. fishing effort and the ability of fish resources Some things that may lead to reduced the to regenerate. In addition to the effect on the production include seasonal influences, or decrease of fishermen catch, this will also may be due to the effect of fishing efforts or directly affect the production of processing even fish stocks. Pelagic fish, especially small industries that use pelagic fish as the main pelagic fish is the main raw material for the raw material. industry of boiled fish, curing, salting, fish The problem of fish resources becomes meal. This was in accordance with the results one of the important problems in the of the research by Damayanti (2014) development of capture fisheries in realizing mentioned that the common types processed the optimal and sustainable capture fisheries by way of boiled fish is a kind of pelagic fish development. The availability of fish such as Decapterus russelli, Selaroides resources is influenced by the internal factors leptolepis, Dussumieria acuta, Sardinella of fish, especially related to the ability of fish gibbosa, Sardinella longiceps and others. The regeneration to environmental changes both same was stated by Sutanto (2015) mentioned due to natural factors and human activities. that the types of fish used as raw materials of Empirical facts showed that the degradation salted fish such as Decapterus russelli, of fish resources is largely due to human JEJAK Journal of Economics and Policy Vol 11 (2) (2018): 263-279 265 activities in exploiting fish resources that was on the red indicator or has exceeded the exceed the limits of the ability of fish to potential of its sustainable potential (Marine regenerate.
