采用室内模拟实验方法研究了刺参(Apostichopus japonicus Selenka)与大叶藻(Zostera marina L.)碎屑之间的营养关系,将大叶藻碎屑与泥质沉积物按照一定的配比作为饵料投喂刺参,测定刺参的特定生长率和排粪率。按照添加大叶藻碎屑比例的不同,实验分为5个处理组,分别为ES0、ES10、ES20、ES40和ES100,大叶藻碎屑含量分别为0%,10%,20%,40%和100%。结果表明,饵料组成显著影响刺参的生长,大叶藻碎屑与泥质沉积物混合物中的有机质含量为17%~20%,水温为13~17℃,刺参的生长效果较好,最大特定生长率为1.54%/d,最大排粪率为1.31g/(个?d)。海草床为刺参提供栖息地的同时,大叶藻脱落腐败后的有机碎屑可以为刺参提供重要的食物来源,这对于刺参的资源恢复和营养生态学方面的研究有着重要的意义。

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/(ind?d)). 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.
