研究对比了5种不同类型的附着基对毛蚶(Scapharca subcrenata)幼虫附着变态的影响。研究发现，聚乙烯网片、红棕帘、波纹板附着基的附苗量显著优于尼龙窗纱和棉布附着基。竖直放置的附着基上附苗量优于水平放置，竖直放置的附着基上、中、下三层苗种附着量也有显著差异，下层苗种附着量显著优于上层和中层。此外，通过比较三种不同颜色的附着基上毛蚶幼虫的附着量，表明深颜色的聚乙烯网片(黑色)较浅颜色的网片(绿色和白色)吸引更多的幼虫附着。因此，在生产过程中通过使用深颜色的聚乙烯网片，并将其放置于水体的中下部将会提高幼虫的附着量，从而获得稳定高效的育苗效果。

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.
