Embodiment Construction

[0006] The experimental implementation site of the present invention is located in a marine aquaculture Co., Ltd. in Putian City, Fujian Province. The water quality conditions of the experimental site are as follows: water temperature 9.8-32.8°C, salinity 30.4-31.7, pH 8.1-8.2, inorganic nitrogen 0.19-0.49mg / L , Phosphate 0.02-0.07mg / L, transparency 0.4-2.6m (average 1.7m), no oil, water quality in line with the National Standard Fishery Water Quality Standard of the People's Republic of China (GB11607-89) requirements. The seawater enters the aquaculture pond after sand filtration and precipitation treatment, which meets the requirements of the Ministry of Agriculture's "Water Quality for Pollution-Free Foods in Sea Aquaculture" (NY5052-2001). The flounder breeding pond is built in a greenhouse with an area of ​​40m 2 , the water depth is 1.2m, and the bottom of the pool is concave, which is conducive to operations such as drainage and sewage absorption. Before the seedlings...

Abstract

A method for culturing the lefteye flounder without environmental pollution includes such steps as filling fresh water in pool, immersing for a certain time, disinfecting, flushing several times, filtering, depositing and disinfecting seawater, filling it in the pool, culturing the fry of bastard halibut in the pool, feeding the granular bait, and regularly exchanging water and applying medicine.

Description

technical field [0001] The invention relates to fish culture, in particular to a method for cultivating pollution-free flounder. Background technique [0002] The flounder is carnivorous and cold water, and the suitable water temperature for growth is 8-24 ℃. In recent years, southern provinces such as Fujian and Guangdong have also begun to breed and breed flounder, and have formed a certain scale of production. However, due to the use of illegal drugs, environmental pollution of aquaculture water or the quality of bait, the quality of aquatic products such as flounder is not satisfactory, and the export is often rejected due to the use of prohibited drugs and excessive microorganisms. Residents are increasingly demanding to clean up "table pollution" and ensure the quality and safety of aquatic food. At present, there are still reports on domestic research on the breeding technology of pollution-free flounder. ...
