A system and method for racetrack biofloculation of shrimp

Abstract

The invention discloses a runway type bioflocculation shrimp farming system and a runway type bioflocculation shrimp farming method. The runway type bioflocculation shrimp farming system comprises an aquiculture area and a bioflocculation constituent cultivation area, wherein the aquiculture area is located at the high end of a pond and is a water inlet end of the system; the bioflocculation constituent cultivation area is located at the low end of the pond and is a water outlet end of the system. According to the system and the method, the build-out cost is lower, the separation of the cultivation area of flocculating constituent and the growth area of shrimps is realized inside the pond, and runway type water flow is created inside the pond through the internal partition and the reverse placement of a waterwheel type aerator; a peristaltic pump can be used for coordinating the generation of bioflocculation constituent with the bait casting action; the separated bioflocculation constituent cultivation area is not only the production area of the bioflocculation constituent, but also is a treatment area for residual feeds, faeces and ammonia nitrogen of the aquiculture area. Practical results indicate that the water quality condition of a test pond is better than that of a contrast pond, and the yield of the test pond is obviously higher than that of the contrast pond.

Description

technical field [0001] The invention relates to a system and a method for realizing runway type biological flocculation shrimp cultivation by applying the biological flocculation technology. Background technique [0002] The protein requirement of aquatic animals is significantly higher than that of mammals. However, only about 20-30% of the fed protein is converted into fish catch, and most of them cannot be utilized and exist in the aquaculture water body. Generally, the C:N in the aquaculture water body is lower than 4.0. According to the characteristics of heterotrophic bacteria growth and metabolism requirements, the researchers proposed that the C:N in the aquaculture water body should be increased to more than 10.75 to promote the massive growth of heterotrophic bacteria in the aquaculture water body, and to drive the formation of microbial flocs (Biofloc) Then effectively control the ammonia nitrogen in the aquaculture water, and apply 15 The method of N tracer ver...
