The grouper fry breeding method strictly controls each link and parameter in the breeding process, thereby improving the breeding quantity and quality of the groupers.
Description
Technical Field
The invention relates to the technical field of aquatic product culture.
Background
The grouper has high protein content and low fat content, and is rich in various inorganic salts, iron, calcium, phosphorus and various vitamins besides amino acids necessary for human metabolism. The nutritive components of fish skin colloid have important functions of enhancing the complete growth of epithelial tissues and promoting the synthesis of collagen cells, and are called as fish for beautifying and protecting skin. Is especially suitable for postpartum women. The grouper has high nutritive value, is rich in protein, vitamin A, vitamin D, calcium, phosphorus, potassium and other nutritional ingredients, is a high-quality edible fish with low fat and high protein, and is one of four Chinese fishes promoted by Hongkong and Australia.
The research on the breeding and breeding of the groupers is actively carried out in many countries in the world, but the artificial propagation of the groupers is a key point and a difficult problem no matter at home or abroad.
Disclosure of Invention
The invention provides a grouper seedling culture method in order to improve the efficiency and quality of artificial propagation of groupers.
The technical scheme adopted by the invention for realizing the purpose is as follows: a grouper fry rearing method comprises the following steps:
(1) clearing the pond;
(2) water is fed, and the water is filtered by a 100-plus-200-mesh bag;
(3) sterilizing, namely adding 0.5-0.8ppm of chlorine dioxide into the seedling culture water for sterilization, and washing the seedling culture water by using a high-pressure water gun;
(4) fertilizing water, fertilizing eel 2 kg/mu and water fertilizing paste 0.5 kg/mu in the water fertilizing pool 2-3 days before egg laying, and pumping water to the incubation pool from 2-3 days before egg laying;
(5) laying eggs, soaking the roe bag in hatching water for 10-20min, pouring out after injecting 1/3 fresh water, and opening inflatable stone to inflate;
(6) opening the bag, laying eggs for 3-4 days, enabling the fries to grow and develop into fissures and eyespots, and unfastening the hatching bag at the moment to enable the fries to enter the pond;
(7) adjusting water, wherein the water temperature is 24-31 ℃, and the pH value is as follows: the pH value is 7.8-8.8, the dissolved oxygen is kept above 5mg/L, and the salinity is 30-33 per mill;
(8) feeding, wherein if the bait of the animals in the pond is insufficient after opening the bag for 7-8 days, 2-3 kg/mu of rotifer or copepods are fed;
(9) and (4) taking the fries out of the pond, stopping feeding for 2 days before the fries are taken out of the pond, draining water to the depth of 0.8-1m, and pulling the net for 2-3 times per pond according to the number of the fries.
And (2) cleaning the seedling raising pond, exposing the seedling raising pond for 7-10 days, then feeding water, and sprinkling quicklime into the whole pond for disinfection.
In the step (3), after 3 to 5 days, each m3The water body is detoxicated by 1 ml.
In the step (6), 0.8-1ppm of electrolytic multi-dimensional or VC is splashed in the whole pond 12 hours before opening the bag.
In the step (7), 1000 g/mu of brown sugar and 500 g/mu of spore bacteria are used for adjusting the pH value, and the whole pool is splashed after the activation for 6-8 h.
The grouper fry breeding method strictly controls each link and parameter in the breeding process, thereby improving the breeding quantity and quality of the groupers.
Detailed Description
