Abstract

One of the problems encountered in coastal areas and small islands in Indonesia is habitat degradation, especially the coral reef. Bottom gillnets have been commonly used by traditional fishermen, but it is not environmentally friendly. When lifting the net, coral rubbles are also taken up because the sinker line and sinker are in direct contact with the sea bottom. The use of bridle line on the sinker line can minimize damages of the bottom habitat. This research aimed at comparing the effect of using bottom gillnet with bridle line and strapping bands on fish catch and coral damages. The bridle line used was 100 cm long, while the strapping band distance intervals were different. This study revealed that addition of strapping bands between the bridle line could improve fish catch compared with the use of anly bridle line. Also, it did not affect the coral lifted.
