Uptake of dissolved free amino acids from sea water by Japanese spiny lobster Panulirus japonicus phyllosoma larvae

本研究确定了日本大螯虾叶瘤幼虫能够通过被膜吸收溶解在海水中的几种游离氨基酸。测定了氨基酸种类和浓度以及幼虫期和蜕皮周期对吸收速率的影响，并证明了吸收过程中氨基酸之间存在相互作用。最后，溶解氨基酸定期浸泡处理明显提高了幼虫的活性、存活率和生长速度。

This study determined that the phyllosoma larvae of Japanese spiny lobster Panulirus japonicus are able to absorb through their integument several kinds of free amino acids dissolved in sea water. It also determined the effects of amino acid type and concentration and of larval stage and molting cycle on the rate of absorption and evidenced the presence of interactions between amino acids during absorption. Finally, periodical immersion treatment with dissolved amino acids clearly improved larval activity, survival, and growth rates.
