Abstract
The mass jade perch fry rearing process includes the following steps: 1. reinforced parent perch incubation after raising in a fish pond, in 1-3 months before laying eggs and through regular flow water irritation; 2. laying egg and incubating by means of setting female perch and male perch in the ratio of 1-1.5 to 1 into the egg laying pond, keeping flow water irritation, injecting echolica for female perch to lay egg, gathering fertilized eggs and incubating in a cement pond with slow flowing water, air inflation, certain water salinity and controlled water temperature; and 3. rearing perch fry in an incubating pond with slow flowing water, air inflation, certain water salinity and controlled water temperature through feeding brine shrimp larva. The said process has high jade perch fry survival rate.
Description
Technical field
The present invention relates to the seedling-cultivating method of a kind of fish, relate in particular to a kind of method that is used for jewel perch (Scortum bacoo) scale breeding.
Background technology
Jewel perch (Scortum Barcoo), English name Jade Perch belongs to the Perciformes ， La ， Ge La of section and belongs in the classification, originate in Australia, is Australian economic freshwater fish, and this oppresses delicious U.S., stings between no flesh, contains meat rate height, and nutritious.In October, 2000, Zhujiang River aquatic products research institute carried out the culture experiment achieving success by Australian aquaculture company (AustralianAquaculture Products) with jewel perch introducing China.In 5～June of calendar year 2001, the Shandong Province also introduces jewel perch seed from Australia and cultures.The breeding of the jewel perch fingerlings artificial of China starts from 2004, though domestic priority has a plurality of units to carry out the artificial propagation of jewel perch because 1, do not pay attention to the antenatal reinforced cultivating of parent population, the big fertilized egg of fine quality of more difficult acquisition amount; 2, fail to provide the water body environment factor of optimized incubating oosperm and fry rearing; 3, the fry rearing stage fails to provide the nutrition suitable openings to cultivate bait, and prelarva initial feeding rate and training shoot survival percent are not high; 4, fry disposition is violent, and the abundance of bait easily causes inadequately from killing and devouring mutually and causes survival rate to descend between nursery stage; Above reason causes the cultivating survival rate of jewel perch seed to be lower than 10% on the whole, and seedling production is difficult to reach the scale of mass, and supply falls short of demand to cause the seed of jewel perch, limited the large-scale development of jewel perch aquaculture.
Summary of the invention
The objective of the invention is to overcome the defective of the existing seedling growing process of jewel perch, a kind of production method with jewel perch scale breeding easy and simple to handle, that the training shoot survival percent is high is provided.
The objective of the invention is to realize by following technical measures: a kind of method of jewel perch scale breeding, it may further comprise the steps:
(1) parent population reinforced cultivating: parent population at ordinary times by 200～250 kilograms of/mu raisings in the fish pond, began to carry out reinforced cultivating in preceding 1～3 month laying eggs, regularly stimulation by running water.
(2) hatching of laying eggs: with the parent population behind the reinforced cultivating in hastening parturition preceding 1 day by female: male=1～1.5: 1 is put in the spawning pond, keep stimulation by running water, inject the medicine of promoting the sexual maturity and make the parent population natural spawning, collection fertilized egg is put into cement pit and is carried out miniflow water, inflation hatching, keep water salinity, the control water temperature.
(3) fry rearing: fry rearing is carried out in the hatchery, control breeding density; Treat to adopt the halogen worm five joint young to feed jewel perch prelarva behind the fry membrane; In the fry rearing process, keep miniflow water, inflation to cultivate and keep water salinity, the control water temperature.Jewel perch seedling is through the cultivation of 20～25 day time, and body length can reach 2.8～3.2 centimetres commodity fry specification.
Reinforced cultivating described in the step (1) is meant at the fish meal of interpolation vitamin E, unsaturated fatty acid of throwing something and feeding to parent population; Wherein vitamin E accounts for 0.5～1%, and unsaturated fatty acid accounts for 0.5～1.5%.
Stimulation by running water described in step (1) and the step (2) is meant that every bath in 3 days once amount of flush water is 4～6% of a pond water volume.
Described in the step (2) be: press HCG 800IU+DOM5mg+LHRH-A to the promote the sexual maturity concrete mode of medicine of parent population injection
2The dosage of 10ug/Kg is injected at twice, and 8 hours at interval, injection volume was 1/3 of a total amount for the first time, and injection volume is 2/3 of a total amount for the second time.
The concrete measure that carries out miniflow water, inflation hatching described in the step (2) is: press 2～40,000 fertilized egg/m in the fishpond
3Water body density carry out fine bourn, filled water amount is regulated between 80～100L/h scope; During inflation, gas stone is by 1～2 piece/m
3Evenly distribute, dissolved oxygen amount remains on more than the 5mg/L.Water temperature is controlled between 26～28 ℃ in the hatching process.
The concrete steps of step (3) are: behind jewel perch prelarva membrane the 3rd day, directly cultivate bait as the opening of jewel perch prelarva with halogen worm (Artemia salina) nauplius, and threw something and fed once every 3 hours; After hatching 3～5 days the time, the artemia nauplii density of throwing something and feeding is 1～2/ml; After hatching 6～9 days the time, the artemia nauplii density of throwing something and feeding is 3～5/ml; After hatching 10～14 days the time, the artemia nauplii density of throwing something and feeding is 8～10/ml; In hatching in the time of back 15 days, artemia nauplii the be satiated with food degree flexible modulation of density of throwing something and feeding according to fry.
Breeding density is controlled at 1～30,000 tails/m in the step (3)
3Water body; The filled water amount of the fine bourn in the fry rearing process is regulated to 200～250L/h; The condition in the condition during inflation and when hatching is identical; Water temperature is controlled between 26～30 ℃ in the cultivating process.
Water salinity described in step (2) and the step (3) is 4～6 ‰.
The present invention compared with prior art has the following advantages: (1) can obtain a large amount of high quality fertilized egg of scophthatmus, for the jewel perch seedling of cultivating high-quality health has been done assurance by antenatal reinforced cultivating jewel perch parent population; (2) keep hatching and the certain salinity of training seedling water body, optimized the water body environment factor of fry rearing; (3) with the open-mouthed bait of halogen worm (Artemia salina) nauplius as jewel perch prelarva, solved the open-mouthed bait difficulty that jewel perch seedling is cultivated, make the initial feeding rate of jewel perch prelarva reach 96～98%; (4) threw something and fed once by corresponding density every 3 hours, guaranteed the abundance of bait, avoided killing and devouring mutually certainly of fry; (5) jewel perch prelarva is through the cultivation of 20～25 day time, and body length can reach 2.8～3.2 centimetres, and the training shoot survival percent reaches 78～85%, has improved the training shoot survival percent of jewel perch greatly, has ensured the mass production of jewel perch seedling.
