A Study of mono multifilament bottom gill net in Rembang waters

Abstract

The mono multifilament bottom gill net was an alternative design to the monofilament bottom gill net for Rembang waters. Monofilament bottom gill net was legal fishing equipment but its use by traditional fishermen in Rembang waters was minimal and this number is now decreasing. This research aimed to analyze effective fish catch of monofilament and mono multifilament bottom gill nets with the addition of swivel and baits. This research employs experimental fishing by comparing fish catch effectiveness between the two types of bottom gill nets. It was conducted in Rembang waters in Central Java from May to June 2018. Treatment variables involved consist of bottom gill net design and fishing time. The ANOVA two-way data analysis was then used to compare results. Results show that fish catch effectiveness of mono multifilament bottom gill net is 66.01%, higher than monofilament bottom gill net, which has 33.99%. It was also found that the highest fish catch effectiveness was attained when the mono multifilament bottom gill net was operated at night (60.08%). Furthermore, the ANOVA analysis (sign 0.05) shows that the design of fishing equipment and fishing time also influence fish catch effectiveness. Hence, it can be concluded that the mono multifilament bottom gill net with swivel and bait operated at night does better at catching demersal fish, compared to its monofilament gill net without swivel and bait counterpart operated during the day.
