海水池塘养殖模式优化:概念、原理与方法

Currently used seawater pond culture models are evaluated, and principles and methods in optimizing pond culture model are discussed in the present paper. The author indicates that application of the traditional polyculture has been limited in single pond. Inputted nutrients such as feed and fertilizer can't be efficiently utilized by animals cultured in a pond with the traditional polyculture, resulting in huge waste discharge, which is regarded as a pollution source to coastal regions. The author suggests it should be possible to put several seawater ponds with different stocking structures together and optimize stocking and management systemically. Compared with the traditionally polycultured seawater ponds, ecological benefits and nutrients transport in the systemically optimized ponds would be amplified. The production performance of the systemically optimized ponds, therefore, would be increased and their pollution would be reduced.
