摘要: 锯缘青蟹是我国主要的海水养殖蟹类之一,其养殖已取得了巨大的经济和社会效益,被视为我国海水养殖的一个新的经济增长点。对锯缘青蟹系列配合饲料进行饲养试验,经32 d饲养的结果表明,饲喂配合饲料的幼蟹生长性能良好、存活率高;经90 d饲养的结果表明,开发的系列配合饲料能满足锯缘青蟹不同生长发育阶段的营养需求和摄食习性,促进锯缘青蟹正常蜕壳生长,且具有良好的诱食性、水中稳定性。Ⅰ期幼蟹饲养90 d的最终存活率达75.9%,每只均重达205.0g。

Abstract: The mud crab (Scylla serrata Forskal, 1775) is a kind of the important marine culture species in China, and its culture is developing in large scale, and given out huge economy and social benefit.Mud crab culture is regarded as a new economy-gaining point.The trail results using the series formulated diets to feed Scylla serrata showed that the developing diets can meet the nutrient requirements and feeding habit for different stages of mud crabs, diets can improved the crabs to ecdysis, grow normally, and had good attractive, stability in water.The growth rate and survival rate of crablets fed with formulated diets were higher during 32 d; The mean final livability of Scylla serrata for 90 days was 75.9%, mean final body weight was 205.0g.
