摘要:

为探索紫海胆(Anthocidaris crassispina)海上筏式养殖的可行性,于2021年4月至2022年9月在福建连江奇达海域开展了紫海胆海上筏式养殖试验。在当地现有的鲍养殖海域,利用筏式养殖设施,定期投喂海带(Laminaria japonica)和龙须菜(Gracilaria lemaneiformis),经过17个月的养殖,紫海胆的壳径达到(47.10±4.07)mm,体质量达到(43.40±8.80)g,性腺指数为4.45%±2.97%。试验结果表明,采用现有鲍海上筏式养殖设施开展紫海胆海上筏式养殖具有一定可行性,但需针对紫海胆棘刺长等特点改进养殖设施。

Abstract:

In order to explore the feasibility of aquaculture of purple sea urchin (Anthocidaris crassispina) in raft, a raft culture experiment of purple sea urchin was carried out in Qida sea area of Lianjiang, Fujian Province from April 2021 to September 2022.In the existing abalone culture sea area, the raft culture facilities were used to feed kelp (Laminaria japonica) and asparagus (Gracilaria lemaneiformis) regularly.After 17 months of breeding, the diameter of the purple sea urchin had reached ( 47.10 ± 4.07 )mm, the body mass had reached ( 43.40 ± 8.80 )g, and the gonadosomatic index was 4.45 % ± 2.97%.The test results showed that it was feasible to use the existing abalone marine raft culture facilities to carry out the marine raft culture of purple sea urchins, but it was necessary to improve the culture facilities according to the characteristics of purple sea urchins such as long thorns.
