Gillnets is a rectangular fishing gear. The main principle of the methods is blocking movement of the fish. The success of its operation depends on the fish presence in passing the net. The improvements of fishing technique on gillnets need to be done to increase the catch weight. The solution is to innovate the use of attractors in the form of lights to attract fish to come to the fishing gear, so that the passive gillnets do not just wait for the fish through it. The study used experimental fishing method with two units of gillnets simultaneously, which each units with lamp and the other without lamp. The objectives of the studies are to get information on the catch composition, to prove the use of a lamp on the gillnets will increase the catch weight and to determine the net position from the lamp that resulted the highest weight. The result showed that (1) the catch in gillnets with LED underwater lamps (JDL) consist of 10 types, or 2 types more than the gillnets without light emitting diode (LED) lamp (JTL). The eight catch composition consists of mackerel, spanish mackerel, barred queenfish, indian mackerel, great barracuda, moonfish, bigbelly pomfret, and giant trevally. The catch composition from JDL were the amberjack and the black pomfret; (2) The use of lamp on the gillnet proven to increase the catch with JDL total weight of fish was 189.765 g; (3) from position of the net shows that the highest weight was at the first position, such as net number 1, 6, 7, and 12 as much as 108.308 g.
