Composition and Catch Rate of Purse Seine Fishery Unit at the Tegal Fish Landing, Central Java

Abstract

Purse seine fishing gear is one of the fishing gear used by the fisherman at the Tegal Fish Landing to catch pelagic fish. This study aims to analyze the composition of purse seine catches and catch rates based on the number of catches and trips to sea, determine the selectivity of purse seine fishing gear base on the number and species. The research method used survey methods and data in quantitative analysis, the analysis of the composition of the catch is secondary to the volume of purse seine catches at Tegal Fish Landing throughout September to November 2019. The capture rate was calculated using secondary data on the number of trips and the total production of purse seine at the Tegal Fish Landing from 2014 to 2018. Selectivity of puse seine fishing gear using primary data includes the number and weight of catches, identification of fishing gear, work equpment, safety equipment, supplies, navigation tools, accident history. The dominant variety of catch species was small pelagic fish, namely Decapterus macrosoma, Sardinella lemuru, and Rastrelliger kanagurta. The largest percentage of catches in September was 52% Decapterus macrosoma, 13% Sardinella lemuru, and Rastrelliger kanagurta. The location of the fishing grounds is in the WPP area 712 and 713 the average CPUE purse seine per year at Tegal Fish Landing was 26.710 kg or 26,7 tons per trip for each vessel. This shows that purse seine capture productivity was still quite low when compared to the size of Gross Tonnage. Purse seine gear for five fishing vessels that landed at Tegal Fish Landing selectively. During the study the proportion of the amount and weight of the five vessels was more thant 60%.
