南方紫海胆增殖放流对虾类和蟹类行为的影响（英文）

Effect of Anthocidaris crassispina Enhancement on the Behavior of Shrimps and Crabs

[目的]探索紫海胆(Anthocidaris crassispina)增殖放流对野生虾类和蟹类行为的影响。[方法]在实验室内开展微宇宙法模拟试验,研究紫海胆增殖放流对野生虾类和蟹类行为的影响。[结果]日本对虾(Penaeus japonicus)、斑节对虾(Penaeus monodon)和近缘新对虾(Metapenaeus affinis)与紫海胆Coexist,紫海胆对日本对虾有一定的吸引特性,但均无危害情况发生;红星梭子蟹(Portunus sanguinolentus)与紫海胆间未发现有行为影响和危害情况,三疣梭子蟹(Portunus trituberculatus)和锈斑蟳(Charybdis feriatus)在数量较多时可能会对紫海胆造成一定的危害,但并不是普遍现象。[结论]该研究结果可为生物行为学和进一步开展紫海胆增殖放流生态风险评价提供参考。

[Objective] The aim was to study the influence of Anthocidaris crassispina enhancement on the behaviors of wild shrimps and crabs. [Method] Simulation ex- periments were carried out in the laboratory to study the effects of A. crassispina enhancement on the behaviors of wild shrimps and crabs. [Result] Penaeus japoni- cus, Penaeus monodon and Metapenaeus affinis could coexist with A. crassispina, and A. crassispina had a certain attraction to Penaeus japonicus, but no harm oc- curred. There were neither behavioral effects nor hazards between Portunus san- guinolentus and A. crassispina. Portunus trituberculatus and Charybdis feriatus might cause some harm to A. crassispina when their quantity was large, but it was not a common phenomenon. [Conclusion[ This research provided references for the bio- logical behavioristics and the further development of ecological risk assessment of A. crassispina enhancement.
