The effect of different substrates on bloody clams (Scapharca subcrenata) larvae settlement and metamorphosis
摘要
Abstract
In the present study, the effect of various substrates on the settlement and metamorphosis of bloody clams, Scapharca subcrenata, was evaluated. The results showed that PVC meshes, red coir rope, plastic plates were preferable substrates. We found that vertically positioned substrateattract had more larvae settlement than horizontally positioned substrates (P<0.05). The difference of settlement densities on upper layer, middle layer and lower layer of vertically positioned substrate was significant (P<0.05). The lower layer of vertically positioned substrate attracted more larvae than middle and upper layers. In addition, the settlement of larvae in the experiments with three different color substrates was compared and it’s showed that deep color PVC meshes (black) attracted significantly more larvae (P<0.05) than light color (white and green). So in the process of production, larvae set-tlement density will be improved by using deep color PVC meshes and placing it in the middle and lower layers of water, which obtain a stable and efficient grow seedlings effect.关键词
