Abstract

The coastal of Makassar Strait is one of main fishing grounds for purse seine vessels from northern part of Java which based at the following landing sites, i.e. Pekalongan, Tegal and Juwana. The purse seine fishery predominantly targets small pelagic fish. This paper attempts to present the current condition of small pelagic fishery in the Makassar Strait. Catch and effort (trip) data between 2004 and 2011 from the three landing sites were used to estimate Maximum Sustainable Yield (MSY) using Schaefer & Fox models. The results showed a decreasing trend in the catch rate, from 30.83 tons/trip in 2004 to 12.27 tons/trip in 2011. The estimated MSY is at the range of 34,705- 37,930 tons with optimum efforts for 2,234-2,500 purse seine trips. Thus the level of purse seine fishing effort in 2011, i.e. 3,078 trips, was exceeding the optimum effort. The decreasing trend in the catch rate may indicate overfishing is occurring between 2004 and 2011. For management of the small pelagic fisheries in the waters of Makassar Strait, important action recommended is fishing effort restrictions. The effort allowed would be only in the range of 2,234-2,500 purse seine trips, and the fishing capacity needs to be controled.

Abstract

Bitung merupakan salah satu sentra pendaratan untuk perikanan huhate. Perikanan huhate bergantung terhadap ketersediaan umpan ikan hidup dan beberapa faktor teknis. Penelitian ini bertujuan untuk mengkaji faktor yang paling berpengaruh terhadap hasil tangkapan per upaya penangkapan (CPUE) ikan cakalang (Katsuwonus pelamis - SKJ). Pengambilan data primer dilaksanakan di atas kapal huhate dari Januari – Mei 2013 yang berbasis di Pelabuhan Perikanan Bitung – Sulawesi Utara. Data logbook kapal serta data harian kapal diperoleh pada saat melakukan pemancingan. Analisis data dilakukan dengan menggunakan analisis Generalized Linear Models (GLM), uji korelasi dan regresi sederhana. Hasil penelitian ini menunjukkan bahwa terdapat empat faktor signifikan berpengaruh terhadap nilai CPUE cakalang (SKJ). Faktor pertama adalah jenis umpan hidup yang digunakan berpengaruh secara signifikan terhadap CPUE SKJ (P< 0,01). Jenis umpan hidup yang berpengaruh signifikan adalah jenis ikan layang dicampur dengan puri merah. Ketiga faktor lainya yaitu suhu permukaan laut (SPL), jumlah pemancing dan daerah penangkapan mempengaruhi CPUE SKJ dengan nilai P < 0.05. Bitung is one of the main landing sites for pole and line fishing vessels. The pole and line fisheries depend on the availability of live fish bait and some technical factors. Objective of this study is to assess several factors that may influence catch per unit effort (CPUE) of skipjack (Katsuwonus pelamis – SKJ). Logbook data and record of daily vessel activities during fishing from January – May 2013 were used in the analysis. The data were analyzed using generalized linear model (GLM), correlation and regression. The results showed that type of live bait was significantly affect the SKJ CPUE (P<0.01). Round scad (Decapterus spp) mixed with anchovy (Stelophorus spp) were giving higher SKJ CPUE as live bait. In addition, sea surface temperature, number of fishers, and fishing location also affect the SKJ CPUE with P <0.05.
