Abstract
An artificial inducement method for spawning and breeding erythroculter ilishaeformis relates to an artificial inducement method for spawning and breeding fish. The method solves the problems of a low hatching rate and a low post-natal survival rate in the existing artificial reproduction method of the erythroculter ilishaeformis. The breeding method comprises the following steps: 1. culturing parent fish in a culture pond; 2. injecting an aphrodisiac agent into the parent fish twice so that the parent fish autogenously spawns; 3. transferring the fish eggs into a hatching barrel for hatching; and 4. transferring fish fry into an outdoor pond after opening an inflatable intestinal canal of a fish maw so as to culture young fishes. The artificial inducement method for spawning and breeding of the erythroculter ilishaeformis can help shorten a breeding period, greatly improve the survival rate and the hatching rate of the parent fish, and obviously improve the economic benefit.
Description
Technical field
The present invention relates to the method for the induced spawning and breeding of a kind of fish.
Background technology
Erythroculter ilishaeformis is commonly called as big whitefish, sticks up face, sticks up shell, white silk, Xing Kaida whitefish, stick up Culter, Culter stickleback, stick up white, whitefish, the son that is in a pout floats silver carp etc., distribution is all arranged in the whole nation, emerging triumphant erythroculter ilishaeformis is independent subspecies of waters, Xinkaihu Lake erythroculter ilishaeformis, it is treasure in the water in Xinkaihu Lake, be one of China four big fresh water name fishes, body is grown greatly, weight can reach tens of kilograms, oppress fresh and tender, steam in clear soup and have the crab meat flavor, fish soup is white, and nutritive value is higher as cow's milk, and every hectogram meat contains protein 18.6 grams, fat 4.6 grams; But because more and more abominable, severe water pollution of natural environment and excessive amount of fishing at present, the output that causes Xinkaihu Lake erythroculter ilishaeformis descend year by year, market price is more up to per kilogram more than 300 yuan; Natural resources reduce day by day, more and more do not satisfy the needs in market.Tackling key problem through scientific and technical personnel in recent years, has broken through the artificial breeding and the pond cultivation technology of erythroculter ilishaeformis.But because the anti-wound ability of this fish is low, lethality was up to more than 60% when product was incubated artificial insemination, and the low and low problem of survival rate in postpartum of generation incubation rate causes producing and the very difficult raising of benefit.
Summary of the invention
The objective of the invention is for there is the low and low problem of survival rate in postpartum of incubation rate in the method that solves existing artificial breeding erythroculter ilishaeformis, and the method for a kind of erythroculter ilishaeformis induced spawning and breeding that proposes.
The method of erythroculter ilishaeformis induced spawning and breeding realizes according to the following steps: one,, pure and fresh with putting into pond water quality after the disinfection of erythroculter ilishaeformis body surface in the annual the first tenday period of a month in late April to May, cultivate in the cultivation pond of sufficient bait; Two, late June is to early July, be to grow normal, fish body under 18～26 ℃ the condition not have the individuality of wound, body surface smooth and physical health in temperature as parent population, human chorionic gonadtropin is expelled in the parent population body, injection once more behind 8～12h at interval, parent population will ovulate voluntarily behind 6～10h; Three, ovum being put into hatching pail hatched 4～6 days; Four, after air bladder inflation intestinal tube is opened, seedling is put into outdoor pond and cultivate into juvenile fish; Wherein in the step 1 in cultivating process every interval 15～20 days, parent population is drawn in the net to train 2～4 times; The total injection volume that wherein injects human chorionic gonadtropin in the step 2 is 1000～1300IU/ kilogram, for the first time the parent population injection volume be human chorionic gonadtropin total injection volume 1/6, milter only carries out a shot, injection volume is 1/2 of a raun injection volume, in the step 2 between parent population the injected volume of the injected volume of raun and milter throw in by 1: 1.1～1.2; Wherein the water velocity of hatching pail was 3～6m/s in preceding 30 minutes in the step 3, and back 20 minutes is 1～3m/s.
By the method artificial breeding erythroculter ilishaeformis of hastening parturition of the present invention, the metabolic rate that adopts the double injection human chorionic gonadtropin to increase parent population greatly to the parent population of selecting also can make colony's gonad development neat, has improved parent population survival rate in postpartum; The method artificial breeding erythroculter ilishaeformis of hastening parturition of the present invention produces artificial breeding and incubates cost decline more than 30% through recording parent population survival rate in postpartum up to more than 90%, and the insemination emergence rate reaches more than 75%.
