Application of foldable cube and cylinder fishing pot in Tuban Regency water

摘要

Fishing pot is an environmentally friendly fishing gear that has been used by fishermen in Indonesia with all kinds of shapes and sizes. This study aimed to determine the composition of the catches using a modified cube folding trap and tube folding trap, as well as provide design information material to develop environmentally-friendly fishing gear. The research was conducted in Socorejo Village, Jenu District, Tuban Regency, East Java, in October-December 2018. The method of this research used experimental fishing with 30 units of cube folding trap and 30 units of tube folding trap. Traps were operated long lines at 10 different coordinate points and the results were analyzed further using the T-test with 95% of confidence level. The catch composition of cube and tube folding traps shows the largest catches in percentage are swimmer crab as much 65% and 57%. The value of catches composition cube and tube folding trap is 0.169 and 0.227 which indicate that cube folding trap is more selective. Based on the results of T-test, total and weight of the catches between cube and tube folding trap show no significant difference. The results conclude that the cube folding trap is more effective with more catches.
