中文摘要：

处于海黄瓜 Apostichopus japonicus 个人的生长率有实质的单个变化。这要求另外的工作分级种子股票并且变长生产时期。我们评估了三个文化方法的影响(免费混合，孤立混合，孤立独自) 在在生长的单个变化上并且估计了在喂，精力变换效率，和在个别地有教养的海黄瓜的单个生长变化之间的关系。不同文化方法，当在孤立混合的处理高耸了时，动物最好成长了(即，尺寸班独立被保持) ，尽管在在在高耸之间的生长的单个变化没有差别，处理组织。在生长的单个变化首先被归因于基因因素。在基因差别在个人之中引起的食物变换效率的差别被认为是变化的起源。单个生长变化的水平可以被相互作用在个人和环境异质之中改变。我们的结果建议除了传统的种子分级，改变海黄瓜的空间分发的底层的一种新类型的设计将有效地在文化在海黄瓜的生长提高生长和还原剂个人变化。

英文摘要：

There is substantial individual variation in the growth rates of sea cucumber Apostiehopus japonicus individuals. This necessitates additional work to grade the seed stock and lengthens the production period. We evaluated the influence of three culture methods （free-mixed, isolated-mixed, isolated-alone） on individual variation in growth and assessed the relationship between feeding, energy conversion efficiency, and individual growth variation in individually cultured sea cucumbers. Of the different culture methods, animals grew best when reared in the isolated-mixed treatment （i.e., size classes were held separately）, though there was no difference in individual variation in growth between rearing treatment groups. The individual variation in growth was primarily attributed to genetic factors. The difference in food conversion efficiency caused by genetic differences among individuals was thought to be the origin of the variance. The level of individual growth variation may be altered by interactions among individuals and environmental heterogeneity. Our results suggest that, in addition to traditional seed grading, design of a new kind of substrate that changes the spatial distribution of sea cucumbers would effectively enhance growth and reduce individual variation in growth of sea cucumbers in culture.
