Squid attractors are used as a place for the squid to lay its eggs which later can be hatched and cultivated to meet the world's demand for cephalophods which currently are exclusively fulfilled from stocks caught in nature. This study aims to determine the effectiveness of squid atractor made by PCV pipe materials, to determine the depth whereas the attractors gave the best results, and to measure the time needen for the eggs to hatch. Two types of squid attractor made by PVC pipe material were used, namely Attractor Type 1 (T1) with cover on the top and both sides of the right and left, and Type 2 (T2) which is given a cover only at the top. Squid attractors were set around a stationary liftnet with a distance of 5 meters. The depth around stationary liftnet are varied with 8 meters depth on the west side, 6-7 meters depth on the north and south side and 5 meters depth on the east side. The results showed that the number of clusters produced was influenced by the type of attractor and the position of setting whereas this positions were reflecting the depth of the water (df = 4, F = 14.74, p <0.05). The number of squid eggs in 1 cluster was amounted to 484 eggs, so the number of eggs produced in this study was 12,584 eggs. Atractor T1 gave the best results compared to T2 atractors (df = 1, F = 21.56, p <0.05). Based on the results of squid eggs found on the attractor, the squid effectively lays its eggs at a depth of 6-8 meters. Squid eggs should be moved from attractor before 23rd day for cultivation purpose.
