A kind of cultivation method of grouper

Abstract

The invention discloses a method for cultivating grouper. The outdoor ecological pond and the indoor nursery pond are connected by pipes, and the algae water in the outdoor ecological pond is pumped into the indoor nursery pond. The bottom of the indoor nursery pond is connected by a drainage pipe. The outdoor ecological pond discharges the tail water from the indoor nursery pond to the outdoor ecological pond, forming a relay cycle grouper nursery system of indoor seedling cultivation + outdoor algae cultivation, which solves the respective problems of ecological nursery breeding in grouper ponds and industrial circulating water breeding. Disadvantages and give full play to the advantages of the two seedling raising methods, and provide sufficient density of SS-type rotifers as opening bait for the open larvae in time during the opening period, so as to ensure that most of the larvae can open smoothly in the opening period at the first time, and in the opening period. During the development stage, high-density live bait is continuously maintained, so that the development of all larvae in the early stage of nursery is relatively synchronized, minimizing individual differences among the same batch of seedlings, avoiding cannibalism, and greatly increasing the number of seedlings and the rate of emergence.

Description

Technical field [0001] The present invention relates to the field of aquaculture, in particular to a cultivation method of grouper. Background technique [0002] Grouper farming is one of the important industries of ocean fish farming in my country, with an annual farming production of 10-15 million tons. In recent years, my country's grouper breeding industry has developed, all parties farmers focus on grouper, mainly from grouper net box cultivating farefish and pond ecological seedlings, and cataract, fry fish technology to make grouper In the artificial breeding controllable environmental gland, it can achieve the ordering production of the fertilizer egg by oxytocity. After the technical breakthrough, the grouper affected by the grouper on the market has increased significantly, and the price has dropped sharply, causing a large number of people to engage in grouper seedlings. The pond ecological seedling technology uses the pond, relatively controllable cultivation environm...

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
