Circulating water aquaculture system for penaeus vannamei inland freshwater pond

Abstract

The invention discloses a circulating water aquaculture system for a penaeus vannamei inland freshwater pond. The circulating water aquaculture system comprises an aquaculture pond, a production channel and a shed body, wherein a multi-parameter water quality detection probe is laid at the bottom of the aquaculture pond; a primary biological purification pond and a secondary biological purification pond are arranged at one end of the aquaculture pond side by side; a buffer pond is arranged on the right side of the secondary biological purification pond; a water pump is arranged at a water outlet of the buffer pond; a water outlet nozzle is fixedly arranged on the inner wall of the aquaculture pond and communicated with the water pump through a pipeline; automatic bait feeders are arrangedat the south end and the north end of the aquaculture pond correspondingly; four-side lifting ventilation films are arranged on four sides of the shed body; and a well water spraying pipeline is arranged at the top of the shed body. The circulating water aquaculture system is not influenced by weather change in a shed temperature mode, is high in controllability and can realize a stable, continuous and efficient intensive aquaculture mode by improving the water quality.

Description

technical field [0001] The invention belongs to the field of culture technology of Penaeus vannamei, and in particular relates to a circulating aquaculture system for inland freshwater ponds of Penaeus vannamei. Background technique [0002] Penaeus vannamei, whose scientific name is Penaeus vannamei, belongs to the phylum Arthropoda. It is a wide-temperature and wide-halt tropical shrimp. It looks exactly like Penaeus sinensis and Penaeus megi. Its average life span can exceed 32 months. Thin, the normal body color is light blue-gray, no markings on the whole body, and the legs are often chalky, so it is called white-limbed shrimp. The meat is delicious and has high economic value. It is the largest shrimp species cultured in the world. There is already a stable and mature upstream and downstream industrial chain in the world, and it can adapt to pure freshwater aquaculture. The development of inland freshwater aquaculture can continue to provide an industrial ecology for p...

AI Technical Summary

Problems solved by technology

[0004] (1) The desalination culture of inland Penaeus vannamei has a low-profit model of low unit yield and one crop per year;

[0005] (2) The breeding process still needs to use a certain amount of brine or sea crystals, which will cause salinization of the inland soil and damage the soil for re-cultivation;

[0006] (3) Diseases are prone to occur during the breeding process, and disinfection and antibiotics may still be used to cause environmental pollution through external discharge;

[0007] (4) The water quality parameters of aquaculture are unstable, the controllability is not high, and they are easily affected by weather changes;

[0008] (5) The overall success rate is not high, and the large-scale and intensive farming model cannot be realized
