Manual breeding method of four gill bass

Abstract

A manual seed breeding method of four gill bass comprises the following steps: preparing breeding facilities, wherein the pond is square, the pond bottom is flat, the silt is less, the drainage and irrigation are convenient, and the average water depth is 0.8 m; and disinfecting with 10 mg / L TCCA (Trichloroisocyanuric) acid within 10 days before placing four gill bass seeds in the pond. Through the adoption of the method, the breeding is scientific and elaborate; the yield-increasing effect is obvious in a short time; the living rate is high; and the method is suitable for industrial large-scale development.

Description

technical field

[0001] The present invention relates to the method for aquaculture, especially a kind of four gill perch artificial cultivation method. Background technique

[0002] Special product of Xiangshui County, produced in the middle and lower reaches of the Guanhe River. The body of the fish is blue-gray, with black spots on both sides and dorsal fin. Because there is a deep fold on the gill cover, it looks like four gills, so it is named "four-gilled perch". Commonly, each piece is about 3-5 catties, and the larger ones can reach dozens of catties. Every year around the "grain of ear" is the fattest season for sea bass. In the Bailiguan River, fishing boats compete and set up nets to fish. At this time, Xiangshui, Shuanggang, Chengang and other places can be seen at any time on the market. The meat of four-gill perch is white and tender. After cooking, the meat is like garlic cloves. The soup is milky white, thick and sticky, and the fragrance is like sweet-sce...

Embodiment Construction

[0009] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0010] A method for artificially cultivating four-gill perch, comprising the following steps:

[0011] Cultivation facilities: square pond with flat bottom, less silt, convenient drainage and irrigation, with an area of ​​about 166 m2 and an average water depth of 0.8 m. Ten days before the fish species are put into the pond, they are disinfected with 10 mg / L strong chlorine. Keep the water quality lean, with a pH of 7.8, fewer types and quantities of zooplankton, and aquatic plants growing around the pond. The pond is equipped with a water purification system, including coral stone, filter cotton, activated carbon, etc. Use micro-pumps to circulate the water, which can not only purify the water quality but also ...
