Breeding method for improved procypris merus capable of growing quickly

Abstract

The invention discloses a procypris merus improved variety breeding method capable of rapidly growing. The procypris merus improved variety breeding method comprises the following steps: step 1, selecting parent fishes; step 2, medicine injection; 3, sperm and egg mixing; step 4, hatching; step 5, feeding food; step 6, transferring; 7, changing the feeding environment; wherein in the first step, firstly, purebred parent fishes which are robust, full, free of diseases and uniform in specification are selected as parent fishes to be induced to spawn; wherein in the step 2, the selected parents are temporarily bred in the spawning pool for 1-2 days, and spawning induction can be carried out; according to the method, the fries in different periods are fed with different foods, so that the fries can grow quickly, meanwhile, before the fries are transferred, different preparation proportions of mixed water are changed, and in the changing process, the proportion of water in the feeding water tank is continuously increased, so that the fries can adapt to the living environment in advance, and the survival rate of the fries is increased. The death rate of the fries is reduced, and normal growth of the fries is facilitated.

Description

technical field [0001] The invention relates to the technical field of the breeding of fine-grained croakers, in particular to a breeding method of fine-grained croakers capable of rapid growth. Background technique [0002] Hehuayu is a kind of carp species with black and translucent body color, namely black carp. It is mainly found in the southern mountainous areas and the northern part of Guangxi. It originally originated in Longshui Township, Quanzhou County, Guilin City. Because the fish grows up after eating the fallen grass flowers, the fish has the fragrance of grass flowers and is named grass flower fish, but the existing grass flower fry grow slowly in the process of breeding, and at the same time, when the fry are transferred to the rearing pond in the process of , Due to the sudden change of the fry living environment, it is easy to reduce the survival rate of the fry. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fast-...

[0002] Hehuayu is a carp species with black and bright body color, that is, black carp. It is mainly found in the southern mountainous area and northern Guangxi. It first originated in Longshui Township, Quanzhou County, Guilin City; Because it grows up after feeding on the grass flowers that fell into the water, the fish meat has the fragrance of grass flowers, so it is named the grass fish. However, the existing grass fish fry grow slowly during the breeding process. , due to sudden changes in the living environment of fry, it is easy to reduce the survival rate of fry
