锯缘青蟹两种养殖模式的比较研究

【目的】比较采用室内工厂化循环水立体养殖模式和传统池塘养殖模式养殖锯缘青蟹(Scylla serrata)的效果,发掘健康高效的锯缘青蟹养殖模式。【方法】用两种养殖模式进行暂养、幼蟹养殖成蟹和培育软壳蟹,并检测其成活率、养殖密度和品相。【结果】相比于传统池塘养殖模式,用室内工厂化循环水立体养殖模式暂养、幼蟹养殖成蟹和软壳蟹的成活率分别提高13.3%,200%,63.6%;养殖密度分别提高1155.5%,3233.3%,1718.2%;品相也更好。【结论】室内工厂化循环水立体养殖模式是锯缘青蟹高效健康养殖的一种新模式。

Comparative Study on Two Cultivation Modes of Scylla serrata

[Objective] By comparing Scylla serrata three-dimensional cultivation using indoor factory recycling water mode and traditional cement pond cultivation mode,the efficient health crab breeding mode was discovered. [Methods] In two models,temporary-keeping,baby crab growing up to a crab,cultivating soft shell crab,survival rate,breeding density and appearance were detected. [Results] Results showed that compared with traditional cement pond cultivation mode,in three-dimensional cultivation using indoor factory recycling water mode the survival rate of temporary-keeping,baby crab growing up to a crab and cultivating soft shell crab increased 13.3%,200%,63.6% with 1155.5%,3233.3%,1718.2% increase of breeding density and improved appearance. [Conclusion] This study concluded that three-dimensional cultivation using indoor factory recycling water mode as a facility fishery,providing a new mode for efficient healthy breeding of Scylla serrata.
