Factory culturing method for grouper

Abstract

The present invention discloses a grouper factory culturing method comprising the following steps: (1) Treatment water for culture: disinfecting and sterilizing culturation water by ozone and ultraviolet radiation, then filtering and detecting and controlling water quality; (2) Selection fry: selecting 12 to 15cm grouper fry without nervous necrosis virus; (3) Culturation for grouper: To discharge culturation water qualified by detected into culture pond, to stock the selected fry into pond, to control the content of dissolved oxygen, ammonia nitrogen, nitrite and bacterial in pond, and to control culture density and PH of culture water, to feed everyday; (4) During culturing procession to recycle treatment culture water, that is to separate protein for culture water, after disinfecting and sterilizing by ozone and ultraviolet radiation to process biological nitrification, and then filtering so as to renew culture water; (5) Pollution absorption, washing pond bottom and changing water each day, keeping pond wall and pond bottom cleaning. This method has high efficiency and environment protecting, using this method to produce grouper having good quality, high yield, health and high survival rate, lower feed coefficient.

Description

technical field [0001] The invention provides an aquaculture method, and in particular relates to a grouper industrialized healthy cultivation method. Background technique [0002] Grouper (Epinephelus sp.) has tender meat, delicious taste, high market price and good sales. In recent years, many countries in Japan, South Korea, Southeast Asia and Oceania are actively carrying out artificial breeding of grouper. Guangdong has a tradition of grouper farming, and it is also the main production area for grouper farming in my country. The basic characteristics of mariculture in the 21st century are high quality, high efficiency, health and sustainable development. In the case of limited fishery resources, the sustainable growth of fishery must seek development in aquaculture fishery, increase the density of aquaculture, increase the output per unit of water body, and appropriately increase the water area that can be cultured. The application of existing traditional aquaculture...

Problems solved by technology

As a result, aquatic animal breeding diseases are increasing year by year. According to the statistics of the national fishery department, the annual national aquaculture production due to disease causes more than 7 billion yuan in losses to the fishery. The occurrence of aquaculture diseases not only restricts the further development of production, but also due to the abuse of antibiotics Drugs such as drugs lead to a decline in the quality of aquatic products, and the food safety of farmed aquatic products cannot be guaranteed, which has largely affected the sustainable development of aquaculture.
