CATCH ANALYSIS AT THE TIME OF FISHING OPERATIONS AND IMMERSING SURFACE GILL NETS IN SEMARANG WATERS, CENTRAL JAVA, INDONESIA

Abstract

The purpose of this study was to catch analysis at the time of fishing operations and immersing surface gill nets in Semarang Waters, Central Java, Indonesia. The research was carried out in March 2021. The research method was experimental fishing. The treatment variables included the morning operating time with 30 minutes and 60 minutes of immersion time, and the evening operating time with 30 minutes and 60 minutes of soaking. All treatments were repeated 7 times each. Data analysis using the Two Way Anova test. The composition of the catch obtained was Milkfish (Chanos Chanos), Long Jawed Mackerel (Rastrelliger sp.), Anchovy Fish (Mystacoleucus padangesis), Threadfin (Eleutheronema tetradactylum), Queen Fish (Scomberoides lysan), Grouper Fish (Epinephelus sp.), Pony Fish (Leiognatus tauvina), Emperors (Lethrinus sp.), Silver Pennah Croaker (Aspericovina jubata), Black Pomfret (Formio niger), Torpedo Scad (Megalaspis cordyla), Spanish Mackerel Fish (Scomberomorus sp.), John’s Snapper (Lutjanidae sp.), Streaked Spinefoot (Sinagus sp.), Tholi Shad (Tenualosa macrura), and Tongue fish (Cynoglossus lingua). The most catches (biomass) were treated in the morning operating time with 60 minutes of immersion. Data analysis showed that there was a significant effect on the best catch with fishing operation time in the morning (sign 0.05) and immersing time for 60 minutes (sign 0.05). There is no significance between the fishing operation time and the immersing time. The most catches (biomass) were treated in the morning operating time with 60 minutes of immersion.
