Abstract

Cannibalism is a major problem in lobster and crab aquaculture. Reducing the aggressive characteristics of lobsters and crabs can improve survival during the culturing process. In this study, juvenile scalloped spiny lobsters () and crucifix crabs () were both cultured under different shelter and live prey conditions. Groups with shelter (seaweed and cotton filter) showed a better survival rate than the control group (no shelter; < 0.05) for both and . Co-culturing with live prey () significantly benefited the juveniles of and visibly increased the survival of juvenile . Although providing shelter is currently the main method for reducing agonistic behavior, it must be continually altered as the lobsters and crabs grow. Live prey can grow and attract lobsters and crabs to hunt them, and live prey can be supplemented at any time. They can also be used as an additional source of income during the harvest season.

摘要

同类相食是龙虾和螃蟹水产养殖中的一个主要问题。降低龙虾和螃蟹的攻击性特征可以提高养殖过程中的存活率。在本研究中，幼年波纹龙虾（）和十字蟹（）均在不同的遮蔽物和活饵条件下进行养殖。有遮蔽物（海藻和棉质滤网）的组对于波纹龙虾和十字蟹而言，其存活率均高于对照组（无遮蔽物；<0.05）。与活饵（）混养对波纹龙虾幼体显著有益，并明显提高了十字蟹幼体的存活率。尽管目前提供遮蔽物是减少攻击行为的主要方法，但随着龙虾和螃蟹的生长，必须不断更换遮蔽物。活饵可以生长并吸引龙虾和螃蟹捕食它们，而且活饵可以随时补充。在收获季节，它们还可以作为额外的收入来源。
