Fishing ground mapping of static fishing gear in Lada Bay waters

Abstract

Various types of fishing gear operated in Lada Bay waters. Data and information regarding fixed or static fishing gear (SFG) are minimal. This research aims to (1) determine the number and size of SFG; and (2) mapping the fishing ground of SFG in Lada Bay. The census method was conducted from August 2018 to April 2019. The identification of SFG and water characteristics were analyzed descriptively. Map of the fishing ground made with GIS. The number of SFG in Lada Bay was 123 units (45 units of fixed lift net and 78 units of the arrier). The fixed lift net sizes range from 10.6-12.7 m with bamboo and areca trees construction. The leader net of the barrier is 100 m, wings 37.5 m, body 10.5 m, and crib 4x4-4x5 m, with bamboo and nets construction. The fishing ground of the fixed lift net is from Tanjung Lesung to the north of Liwungan Island. While the barrier is from Tanjung Lesung to Ciseukeut River. Water characteristics for fixed lift net are temperature 27.2-29°C, pH 7.7-9, salinity 30-33 ppt, depth 11-16 m, and brightness 2.8-3.8 m. The water condition for barriers is temperature 27.3-30°C, salinity 30-34 ppt, current 0.1-0.3 m/s, and depth 1.3-7.7 m with the substrate of muddy sand and sandy coral.
