The effect of different spat collectors on attachment and growth of oyster spat (Crassostrea gigas) in Alue Naga

Abstract Oyster (crassostrea gigas) is one of the potential bivalves that can be developed to increase economic income. One stages how cultivate oysters initial process sticking oyster spats. This study aims analyze success attachment and growth spats in each collector factors influence Pacific collector. method used experimental using a completely randomized design model (RAL) with 3 treatments, treatment times repetition. The collectors are plastic fiber, coconut shell, tires. results showed average adhesion was 13.7% cover attachment, b had an percentage 6.8%, while c 10.12%. spat size has 1.1 cm, 0.7 0.8 cm.
