Abstract

The invention discloses a Chinese black sleeper culture method and solves the problems that Chinese black sleepers grow slowly and feed waste is apt to caused by adopting the existing Chinese black sleeper culture method in the prior art. The Chinese black sleeper culture method comprises the following steps: 1) fishpond selection; 2) fishpond dredging and water fertilization; 3) fry putting-in; 4) culture. The Chinese black sleeper culture method has the advantages that the steps are simple, the operability is high and the conditions for Chinese black sleeper culture are optimized; since different feeding periods and feeding amounts are adopted by using a biological compensation mechanism aiming at fish fries with different body length and optimized mixed feed is used, the growth of the Chinese black sleepers is effectively promoted, the culture period is shortened, the feed utilization ratio and the survival rate are improved and the culture benefits are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating Chinese snakeheads. [0002] Background technique [0003] Chinese snakeheads belong to Osteichthyes, Perciformes, Goby suborders, and Channaidae, commonly known as "mullet", "mud fish", "earth fish", etc., and are a kind of warm-water shallow sea fish. It is distributed in salt water areas such as coastal areas, estuaries, and harbors in southern my country. It likes to inhabit sandy mud bottom or reef areas, and lives in caves. [0004] Channa sinensis is a rare marine fish with delicate meat, delicious taste, rich nutrition and high economic value. In recent years, the success of artificial breeding of Channa sinensis has laid a foundation for the development of Channa sinensis aquaculture. [0005] For example, Publication No. CN101273716A, the Chinese patent on October 1, 2008 discloses a method for cultivating Chinese snakehead carp. The spec...
