| Research Abstract |
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.
