Embodiment Construction

[0019] A method for healthy and efficient breeding of saddle grouper in deep-water anti-wind and wave net cages, comprising the following steps:

[0020] 1. Selection of breeding sea area

[0021] The breeding area is selected in the Shiyu sea area of ​​the Yongle Islands in the Xisha. There are natural barriers on islands and reefs in this sea area, and the effect of sheltering from the wind is relatively good. The annual variation range is 25-33°C, the perennial wave height is 0.1-2.0 m, the annual average wind speed is 6.0 m / s, the annual ocean current is 0.1-1.2 m / s, the pH is 7.8-8.6, the transparency is 25-40 m, the dissolved oxygen >6mg / L, ammonia nitrogen<0.1 mg / L, nitrite<0.5μg / L, hydrogen sulfide<0.05 mg / L. The water quality index is in full compliance with the growth requirements of saddle grouper breeding and the national standard "Safety and Quality of Agricultural Products--Environmental Requirements for Aquatic Products Origin" and the standard of the Ministry ...

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...
