Abstract

The invention discloses a culture method for good-quality and high-yield catfish. The culture method includes the first step of zygote spawning induction, the second step of zygote hatching and the third step of fry rearing. By conducting strict control and reasonable coordination at all catfish growth and reproduction stages, the yield of catfish is increased by 25-35% finally, the quality of catfish is also improved obviously, and catfish grow fast, can be marketed ahead of time and have very strong market competitiveness. The culture method is reasonable, standard and suitable for large-area culture and popularization and has great economic benefits.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating high-quality and high-yield catfish.
