Abstract

A purse seine is a tool (gear) used to catch pelagic fish that form schools. The aims of this study were 1) to determine the effect of different catches using Mini Purse Seine fishing gear in the morning and evening, 2) to find out the most effective time of catching fish using Mini Purse Seine fishing gear, and 3) To find out composition of the catch and the type of fish caught in the Mini purse seine fishing gear in the morning and at night. The method used in this study was an experimental method with a completely randomized design. This research was conducted in the waters of Ganggelang Village, Gangga District, North Lombok Regency. The results showed that there was no effect of differences in fish catches using Mini purse seine fishing gear in the morning and at night, but there were differences in the composition of fish catches in the morning and at night. The catch of fish at night is more: 1,028 fish while in the morning around: 620 fish, so the effective time for catching fish using the Mini Purse Seine fishing gear is at night. The most dominant type of fish caught in the morning was 175 mackerel and 295 julung-julung fish at night

Abstract

This study aims to determine the effectiveness and differences in the results of different types of Mesh sizes using Basic Gill Net Fishing Equipment (Bottom Gill Net) on fish catches, and to determine the composition of the types of fish caught. The method used in this study was an experimental method with a completely randomized design (CRD). The research was carried out in the waters of Puyahan Hamlet, Lembar Selatan Village, Lembar District, West Lombok Regency. The results of the study based on Sidik Diversity Analysis (ANASRA) showed that there was a "very significant" different effect on the different Mesh size type treatments in units of weight (kg) where (F count 10.43 > F table 1% 5.95). The results also showed that the types of fish caught during the study used 4 types of mesh sizes on basic gill nets, with the most in treatment 1st repetition 3 as much as 4.9 kg and the least in treatment 4th repetition 2 as much as 1 kg. overall the highest catch was obtained in treatment 1 (mesh size 1.5 inches) as much as 16.9 kg (36.03%) and the least was obtained in treatment 4 (mesh size 2.5 inches) as much as 7.4 kg ( 15.80%). The types of fish caught are: Lemuru, Rajungan, Grouper, Tembang, Beronang, Layur), white pomfret, seed jackfruit/kuniran, Tiga waja.
