Healthy and efficient method for cultivating giant groupers by deepwater anti-stormy waves cages

Abstract

The invention discloses a healthy and efficient method for cultivating giant groupers by deepwater anti-stormy waves cages, which comprises the following steps: (1) selection of a cultivating sea area: the cultivating sea area is an opening sea area with reef island shields, smaller stormy waves, more smooth tide and above 15m of depth of water; (2) requirements of cage facilities: the cages have the capability of fighting against 12-level typhoon and the rough sea with a height of above 5 cm; (3) selection and stocking of the giant grouper fries: injury-free giant grouper fries with robust physique and consistent specifications are selected and then soaked and sterilized by fresh water before being fed; (4) feeding technique: after being hungered for 2 days, the giant grouper fries are recovered to feed for 2 days with the baits of iced and fresh trash fishes, and controlled to keep eight full at every time, and 0.1 to 0.3% of amino electrolytic polyvitamines and 0.02 to 0.04% of garlicin are added based on the weight of the baits in the baits; and (5) feeding and management. The method has the characteristics of being simple to cultivate and operate and less in bait investment, and the obtained nuisanceless cultivating giant groupers have the characteristics of high yield, good quality, low bait coefficient, high survival rate and fast growth speed and the like.

Description

technical field [0001] The invention relates to a deep-water cage culture method for aquatic products, in particular to a healthy and high-efficiency culture method for saddle grouper deep-water storm-resistant net cages in the open sea area of ​​the South China Sea, and belongs to the technical field of fish aquatic organism culture in agricultural aquaculture. Background technique [0002] Saddle grouper (Epinephelus lanceolatus), commonly known as gentian grouper and dragon grouper, belongs to Osteichthyes (Osteichthyes) Perciformes (Perciformes), Serranidae (Serranidae), grouper subfamily (Epinephelinae), grouper Spotted fish (Epinephelus) is a warm-water marine bottom coral reef fish. It is one of the largest species of grouper and is known as the king of groupers. Saddle grouper has fast growth, strong disease resistance, delicious meat, high nutritional, medicinal and ornamental value, and because its artificial propagation technology is not yet mature, its market pr...

Problems solved by technology

At present, the application of traditional aquaculture technology can no longer meet the requirements of the development of aquaculture in China, because the traditional aquaculture method has been difficult to greatly increase the yield per unit area, coupled with the frequent occurrence of diseases and serious drug residues, etc., resulting in a decline in the comparative efficiency of aquaculture

According to the statistics of the national fishery department, the annual loss of aquaculture production due to disease in the country is more than 7 billion yuan. The food safety of aquatic products cannot be guaranteed, which greatly affects the sustainable development of aquaculture industry
