Abstract

The invention discloses a fish and shellfish relay recirculating aquaculture method for a sea water pond. According to the method, a traditional sea water pond is transformed, fish tanks and corresponding supporting facilities are constructed, and a mode of combining captive culture of fish and intensive culture of shellfish based on circulating water is adopted; nutrient substances such as excrement, residual feeds and the like of fish can be effectively used for culturing algae, good basic baits are provided for the shellfish, and the problems of water eutrophication and pollution of aquaculture are solved fundamentally; recycling of aquaculture wastewater, zero emission of aquaculture tail water and maximum economic benefit and ecological benefit are realized; and the economic benefit of aquaculture of the sea water pond is increased, and environmental friendliness is realized.

Description

technical field [0001] The invention relates to the field of aquaculture technology, in particular to a seawater pond fish and shellfish relay circulation aquaculture method. Background technique [0002] In the prior art, most of the traditional seawater ponds cannot circulate water for cultivation, resulting in low cultivation quality, and also need to regularly replace pond water and discharge sewage, resulting in pollution problems and low economic benefits. And the quality is not very satisfactory, therefore, there is room for improvement. Contents of the invention [0003] The purpose of the present invention is to provide a seawater pond fish and shellfish relay circulating aquaculture method in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention comprises the following steps: [0006] S1 pond conditions: four ponds with an area of ​​100 mu; 15 standa...
