Eksplorasi Daerah Penangkapan Ikan Cakalang Melalui Analisis Suhu Permukaan Laut dan Hasil Tangkapan di Perairan Teluk Palabuhanratu

Abstract

fishing ground condition is usually affected by oceanographic parameters. One of the oceanographic parameters that used in forecasting the availability of pelagic species such as skipjack is sea surface temperature (SST). Skipjack fish is the main target for boat seine net fisheries at palabuhanratu waters in June until October. Information about the potential skipjack fishing ground is very important in order to optimize fishing operation. The purpose of this study were: to determine the SST distribution, to analyze the catch number and length size composition, and to explore the potential skipjack fishing ground at Palabuhanratu waters in August until October 2007. The research undergoes two stages. The first stage was conducted at Palabuhanratu Bay waters in August-October 2007, use survey method, with follow ten samples of boat seine net (payang). The second stage conducted in December 2007 to collect the SST data, which downloaded from the internet. The range of SST at Palabuhanratu Bay waters ranged from 22 C to 29 C in August 2007, 21 C to 27 C in September 2007, and 20 C to 31 C in October 2007. The SST had not significant effect on catch number of skipjack at Palabuhanratu waters during August until October 2007, but affect to the size distribution. The big skipjack distributed at the wide range of SST, but the small skipjack distributed at the narrow range os SST. The potential fishing ground of skipjack in Palabuhanratu Bay during September 2007 was found at Teluk Ciletuh, Ujung Karangbentang, Cimaja, Teluk Cikepuh, Ujung Genteng, and Gedogan waters.
