Epinephelus culture method

Abstract

The invention discloses an epinephelus culture method. An outdoor ecological pond and an indoor fry breeding pond are connected through a pipeline, alga water in the outdoor ecological pond is pumpedinto the indoor fry breeding pond, a water discharge tube is arranged at the bottom of the indoor fry breeding pond and communicates with the outdoor ecological pond, tail water in the indoor fry breeding pond is discharged into the outdoor ecological pond, then a relay circulation epinephelus fry culture system with indoor fry culture and outdoor alga culture is formed, respective defects of ecological fry culture of an epinephelus pond and fry culture of factory-like circulation water are solved, advantages of the two fry breeding methods are taken into play sufficiently, SS type rotifera ofa sufficient density are provided as a starter feed for larva fishes starting to take feed at a starter stage, it ensures that most larva fishes can start to take feed smoothly at a first moment at the starter stage, live baits of a high density are continuously maintained at a larva fish development stage, all larva fishes can develop relatively synchronously at an early stage of fry breeding, individual differences of a same batch of fries can be reduced as much as possible, cannibalism can be avoided, the fry number can be greatly increased, and the fry rate can be increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating grouper. Background technique [0002] Grouper farming is one of the important industries of marine fish farming in my country, with an annual breeding output of 100,000-150,000 tons. In recent years, with the rapid development of the grouper aquaculture industry in my country, the breeding and research efforts of all parties have focused on grouper, mainly due to the cultivation of broodstock in grouper cages and ecological breeding in ponds. The technology of breeding broodstock in cages has made grouper broodstock Under the controllable environment of artificial breeding, the gonads develop, and fertilized eggs can be produced on order through induced labor. After the breakthrough of this technology, the fertilized eggs of grouper on the market have increased greatly, and the price has dropped sharply, so that a large number of people can engage in ...

AI Technical Summary

Problems solved by technology

Although industrial circulating water grouper seedlings have the above-mentioned many advantages, due to the high cost of facilities, difficulty in mastering technology, high quality requirements for personnel, and difficulty in ensuring the supply of palatable and active bait at various stages, pond ecological seedlings still account for the majority of seedlings on the market. most
