Description

A culture method of California sea bass

technical field

The invention belongs to the technical field of aquaculture, in particular to a method for culturing California sea bass.

Background technique

California sea bass, formerly known as largemouth bass, belongs to the order Perciformes, Sunfish family, rich in thiamine, protein, riboflavin, niacin, dietary fiber, vitamin C, vitamin E, vitamin A, cholesterol, carotene, retinoids Alcohol, magnesium, copper, selenium and other nutrients needed by the human body can nourish the liver, kidney, spleen and stomach, and also have a curative effect on colds and coughs; in addition, perch can also treat fetal disturbances, production of less milk, etc., and expectant mothers and mothers to eat Sea bass can replenish the body without causing excess nutrition and lead to obesity. It is a good product for fitness and blood, spleen and Qi, and health.

At present, the breeding methods of California sea bass have low survival rate, low density, slow growth rate and poor economic benefits. Although California sea bass can spawn naturally in ponds with fresh water and aquatic plants, the spawning rate is low and the fry size is uneven. It is easy to kill each other, and the breeding density is not well controlled, and the individual specifications are seriously differentiated. In the breeding process, the nutrition of the bait is not comprehensive, and the bait is mainly chilled fish or small fish, and the supply of vitamins and minerals is insufficient; in addition, the water quality requirements are also very strict in the California sea bass breeding process, and pesticides and water pollution will cause Disease and mortality in California bass. Based on the above reasons, it is necessary to improve the existing artificial breeding and seedling technology of California sea bass to improve the quality of artificial breeding.
