Abstract
The invention provides a method for industrially artificially breeding golden drum fish, which realizes the industrial artificially breeding of the golden drum fish by laying a fishpond, managing water quality, putting density, feeding feed and constructing an ecological environment, and realizes the aims of quick growth and high survival rate of the golden drum fish, wherein the survival rate of the golden drum fish is higher than 90 percent, and the average weight of the cultured golden drum fish fries after 5 months is higher than 290g.
Description
Technical Field
