刺参密度对鲍参混养效果的影响

摘要

Mixed culture of abalone and sea cucumber was conducted in captivity of cement pool ,five groups were set up by the sea cucumber density (0 ,1 ,3 ,5 ,and 7) with the same density of abalone ,which was 40 per layer of the raising cage at first ,and then 25 per layer after thinning ;the amounts of sea cucumber of all treatments were untouched during the whole test .Growth performances of abalone and sea cucumber were detected at 510 d .The results showed no significant correlations between the sea cucumber density and the survival rate ,weight of abalone and sea cucumber in summer ,and the best sea cucumber density for mixed culture was proved to be 2-3 per layer of the cage in this experiment .%沿用水泥池笼养成鲍模式进行鲍参混养生产试验。固定幼鲍放养密度，分设5个刺参 A postichopus j aponicus Selenk混养密度组。起始幼鲍放养密度为每层40粒，各组每层分别混养刺参0（对照）、1、3、5和7头。度夏后疏苗续养，幼鲍放养密度为25粒·层-1。各组刺参数量顺其自然存活数不变。经度夏历时510 d出池检数。经统计分析，鲍参混养度夏阶段，鲍和刺参的成活率、规格与混养刺参密度之间的相关性都不显著（双侧， P＞0.05）。本次鲍参混养生产试验结果表明混养刺参密度每层2～3头为宜。
