Abstract

Soma landra is classified as drift gillnet which rectangular shaped and it equipped with  floats, head rope, buoy rope, towing rope and sign buoy. In operation, it is installed in a position to cut the current direction with the intention of blocking the fish motion. The influence of moon phase is one of the factors that is closely related to fish behavior, where one of them is interested in light. Besides the brightness of the moonlight can be affected to the efficiency of capture. Therefore, the aims of this study were determined the effect of moon phase on catches and determined the catches at each moon phase. Randomized Block Design (RBD) was used in this study. The analyzed indicated that difference or reject Ho, means there are differences in catches in each moon phase. The species of fish caught is flying fish in the local language known as Marluga (Cypsilirusolegoleptis) as a target fishes with a total catch of 364.On the full moon as many as 106 (29.12%), the final perennial of 57 (15.66%), the dark moon of 79 (21.70%) and the initial peraniage of 122 fishes (33.52%).

Abstract

The aims of this study to analyze the differences the catch of the “noru” fishing gear using nipple rubber and silk fibre lures, as well as to identify the catches  obtained. Small pelagic fish are organisms that live in the open sea, separated from the bottom of the water and towards the surface layer. These fish generally like to be in groups, both with their groups and with other types of fish. Also have positive phototaxis (attracted to light) and are attracted to floating objects. Bait is an important factor in increasing the effectiveness of catching small pelagic fish using “noru” fishing gear or hand lines. The interest of artifial bait in this fishing gear has several criteria, including: the shape of the bait must be similar to shape of food, easy visible because of the color and the bait looks alive when the gear is operated. The results of the study showed that noru (hand line) to used nipple rubber lures gave more catches compared to using silk fibre lures. From the catch, there were 4 species of fish caught using nipple rubber lures, namely yellowstrip scad, bigeye scad, trevally and Indian mackerel while using silk fiber lures 2 species of fish, namely  yellowstrip scad and bigeye scad.
