Judul: Analisis Bioekonomi Sebagai Dasar Pengelolaan Sumberdaya Ikan Tuna Sirip Kuning (Thunnus albacares Bonnaterre, 1788) di PPN Palabuhanratu, Sukabumi.
Abstrak: The high demand and production of yellowfin tuna in Palabuhanratu led to the increasing of yellowfin tuna exploitation and potentially affect the biology and sustainability of fishing effort. This study aims to assess bioeconomy approache based on stock status of yellowfin tuna landed in Palabuhanratu. MEY bioeconomy model results obtained optimal production conditions of 1690 tons/year and the effort of 221 trips/year with economic rent of Rp. 60 billion/year. MSY obtained by 1783/year and the effort of 286 trips/years with economic rents of Rp. 55 billion/year. Open access conditions obtained by the amount of production of 1253 tons/year and the effort of 442 trips/years with economic rent of Rp. 0. Results of this study illustrate that the stock of yellowfin tuna is overexploited both economically (MEY) and biology (MSY).

Judul: Kajian Bioekonomi Perikanan Rawai Tuna di PPN Palabuhanratu, Sukabumi, Jawa Barat
Abstrak: High demand and production of tuna fish in PPN Palabuhanratu has caused exploitation of tuna increased and potentially affect the biological condition and sustainability of fishing business. This study aimed to know biological condition, utilization status, and optimum management of tuna fish resources. Diversity index of shannon-wiener (H’), length at first maturity, length-weight relationships, and bioeconomy model was used in this study for data analyses. Result of this study show that the H’ value was 1.60-2.42. Based on the length at first maturity parameter, 3.84 - 41.02 % for bigeye tuna, 0.72% for yellowfin tuna, and 65.63% for swordfish was lower than unallowable catch size. The length-weight relationships of bigeye and yellowfin tuna were indicated negative allometric growth model, whereas swordfish positive allometry. Actual effort of tuna fishery in PPN Palabuhanratu was not indicated a biological overfishing condition, however it indicated an economical overfishing condition. Bioeconomy optimalization was achieved at fishing effort of 597 trips, production of 2481.14 tons, and economic rent of Rp 67.704.000.000,-.
