大叶藻碎屑作为刺参食物来源的实验研究
Evaluation of eelgrass debris as a food source for Aposticho-pus japonicas
摘要
Abstract
In this study, the nutrient relations between Zostera marina L. and Apostichopus japonicus Selenka were investigated using lab simulating experiments. A mixture of Z. marina debris and seafloor surface sediments was used as food to feed A. japonicus, and the specific growth rate and feces production rate were measured. According to Z. marina debris proportion, we designed five experiment treatments including ES0 (0%), ES10 (10%), ES20 (20%), ES40 (40%) and ES100 (100%). The results showed that the food had a great influence on growth of A. japonicus. The organic content of mixture of Z. marina debris and seafloor surface sediments was 17%~20% and the most suitable water temperature was 13~17℃, which led to higher specific growth rate (1.54%/d) and feces production rate (1.31g/(indּd)). Seagrass bed can provide not only habitat for A. japonicus, but also food source for the latter, which is of significance to A. japonicus resource restoration and nutritional ecology research.关键词
