Problems solved by technology

On the one hand, the method of artificial induction is cumbersome and harmful to the parents of the bald fish. On the other hand, the breeding season of the bald fish is still in May and June, which cannot solve the problem of stable supply and demand for the bald fish in the consumer market or scientific research.

Embodiment 1

[0037] Effects of sand and gravel and slight water flow on the reproduction of baldfish

[0038] 1. Materials and Methods

[0039] Select healthy parents of bald fish and raise them in the original ecological tank that imitates the living conditions of bald fish. During the breeding period of bald fish, select 16 active male bald fish with similar body length and weight; select swollen abdomen and obvious ovary outline , 16 female light-lipped fishes with soft abdomen, similar body length and weight, and active state; the male fish and the female fish were divided into four groups equally, the first group was the control group, and the remaining three groups were the experimental groups.

[0040] Place 8 fish tanks of 50×30×25cm in the greenhouse and divide them into four groups A, B, C and D. The four tanks of the first group and the second group are all around the fish tank at an angle of 45° to the tank wall. Set up a water outlet in a clockwise direction, based on the sta...

Embodiment 2

[0059] A kind of artificial temperature-controlled breeding method of light lip fish, such as Figure 1-4 As shown, a culture pond 10 and a breeding pond 20 of a size of 7 × 7m are set in the greenhouse, and the pond circumference of the culture pond 10 and the breeding pond 20 is provided with a water inlet pipe 30, and the bottom of the pond is a funnel-shaped depression in the middle. A water outlet pipe 11 is arranged in the center. The water inlet pipe 30 of the breeding pool 20 is also provided with a water control pipe 31, the angle between the water control pipe 31 and the water inlet pipe 30 is 45 °, and a water control pipe 31 is respectively set around the breeding pool 20, and four control pipes The water pipe 31 is arranged on the water inlet pipe 30 in a counterclockwise direction. When the breeding pond 20 is filled with water, the water flow enters the breeding pond 20 at a certain flow rate from the four water control pipes 31, driving the water body in the b...

Embodiment 3

[0068] On the basis of embodiment 2, carry out the artificial temperature control early breeding of light-lipped fish, specifically:

[0069] Around November of last year, some healthy and adult female and male light-lipped fishes raised in the breeding pond 10 were selected to be cultivated as parents, and the water temperature in the breeding pond 10 was maintained at 22-25°C. From February to March of that year, when the chasing behavior started among the parental bald fish, one active male bald fish with a similar starting time of the chasing behavior was fished out, and an active female bald fish with a swollen abdomen and obvious ovary outline was fished out. 1 tail of fish is put into the breeding pond 20 jointly. Sandstones are laid on the bottom of the breeding pond 20, and the vortex flow is produced by the water control pipe 31 in the pond. After about 15 days, the male fish and the female fish begin to mate. Fish out, and the fertilized eggs will hatch in about 2-...

Abstract

The invention relates to a fish breeding technology, and particularly relates to an artificial temperature-controlled breeding method for acrossocheilus fasciatus. The method comprises the steps that acrossocheilus fasciatus parents are bred indoors from November of the last year to January of the current year, after the parents are sexually mature in February to March of the current year, the parents are transferred from a culture pond to a breeding pond for breeding half a month before breeding, after the parents are copulated and spawn and fertilized, the parents are fished out, fertilized eggs are left for continuous incubation, and when fry bodies grow to 1 cm, the fish fries are transferred to the outdoors for continuous breeding. According to the method, vortex flow is made in a breeding pool water body, sand and stone are laid at the pool bottom, water flow and the sand and stone are used for jointly stimulating ovulation and sperm excretion of acrossocheilus fasciatus, the breeding time of acrossocheilus fasciatus is advanced to the end of March in the mode that the temperature is regulated and controlled through a greenhouse, and the problem that acrossocheilus fasciatus cannot be stably supplied for a long time due to breeding limitation is solved.

Description

technical field [0001] The invention relates to fish breeding technology, in particular to an artificial temperature-controlled breeding method for bald fish. [0002] technical background [0003] Light-lipped fish, also known as grouper and silk fish, is mainly distributed in streams in Anhui, Jiangsu, Zhejiang, Fujian and other places. Its meat is delicious and it is one of the main species of economic fish. The growth and reproduction of bald fish have high requirements on water quality. Due to the destruction of water source environment and overfishing, the number of wild bald fish is decreasing. The double value of protection. [0004] The spawning season of smooth lip fish is generally from May to August, and the peak breeding period is from June to July. Although the existing technology of artificially breeding smooth-lipped fish has made some progress in terms of hatching and survival rate, due to the lack of research on the breeding mechanism of smooth-lipped fish...
