[0026] Materials and Methods

[0027] 1.1 Test location

[0028] The test was carried out in the breeding base of Hangzhou Wanjue Agricultural Development Co., Ltd. in the 10th section of reclamation in Xiaoshan District, Hangzhou City. The base is the production area of ​​pollution-free aquatic products in Zhejiang Province, with convenient transportation and sufficient sunlight. The Shierdai Henghe River on the south side of the farm has a pH value of 8.2 to 8.7, a salinity of 1‰ to 2‰, and good inflow and drainage conditions.

[0029] 1.2 Construction of circulating water aquaculture system

[0030] The system consists of the vannamei culture area (circulating water treatment area), flowing water fish tank, sediment collection tank, etc.

[0031] 1.2.1 Pond construction

[0032] The pond is constructed by excavating earth from the fruit plantation. It is 184 meters long and 123 meters wide from east to west. The slope ratio is 1:1.5. The soil ridge and the bottom of the ...

Abstract

The invention relates to the field of aquaculture, in particular to a method for cultivating Litopenaeus vannamei through a circulating water fish-farming system. According to the method, Mylopharyngodon piceus, Ctenopharyngodon idella and Lateolabrax japonicus are farmed in a running water cultivating unit, and Litopenaeus vannamei are cultivated in a large pond. For a test pond having an area of 32.9 mu, fishes and shrimps of 49.18 tons in total can be produced by two crops in one year, the production goes to the yield per mu of 1494.8 kg, total output value is 969600 yuan, average output value per mu is 29470 yuan, total materialized cost is 555000 yuan, total profit is 414600 yuan, and average profit per mu is 12602 yuan; the whole cultivating process is free of emission of cultivation wastewater, zero emission of cultivation tail water is achieved, and ecological, economic and social benefits are good.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating Penaeus vannamei in a circulating water fish farming system. Background technique [0002] Running water fish culture (running water fish culture) is a method of high-density intensive fish farming in a fish pond with water exchange. Generally, reservoirs, lakes, rivers, mountain streams, springs, etc. are used to continuously flow through the fish pond with the help of water level differences, drainage or interception facilities, and water pumps, or to purify the discharged water and then inject it into the fish pond. Since the water flow plays the role of inputting dissolved oxygen and removing fish excrement, the pool water can maintain good water quality, which creates conditions for high-density intensive breeding of fish. [0003] Chinese invention patent (application number: 201310336799.7, application date: 2013.08.05) discloses a circulating water fis...
