KOREKSI KEKENDURAN TRAMMEL NET

Abstract

Trammel net has ability to catch demersal organisms which is dominated at the bottom of its net body. It is caused the slackness of trammel net is only found at that section. This study tried to increase the slackness of the nets at the different positions. The aims are to determine the catchs composition and to prove whether the increasing of the slackness will affect the number of catchs. This research was conducted by using 3 trammel nets as control (TK) with one slackness and 3 treated trammel nets (TP) with 3 slackness. The whole trammel net were operated with total of 35 settings at Lontar waters. The results showed that the increasing of slackness did not affect the catchs composition. Each trammel net resulted the same composition of catchs, namely four species of shrimps, ten species of demersal fishes, two species of crabs and one species of non demersal fishes. Trammel net TP resulted 581 individuals (20,10 kg) which is higher than trammel net TK with 277 individuals (7,38 kg).
