Abstract
The invention discloses a burbot full-artificial ecological control natural breeding technology. The technology comprises the following steps: (1) selecting burbot adult fish which is bred for over 3 years with large body, robust constitution and no surface damage as parent fish for spawning; (2) performing autumn strengthen breeding on the parent fish to ensure that the sexual gland thereof can be completely developed; (3) putting the parent fish into a spawning pond according to a ratio of male to female of 1:2 for three-month winter low-temperature breeding; (4) simulating natural conditions to stimulate the parent fish to spawn; and (5) transplanting the collected germ cells in spawning equipment for hatching in running water. The technology has the advantages of low cost, simple operation, small damage to the parent fish and high survival rate of delivered parent fish, low requirement to breeding conditions and technical level of operators and is easy to popularize.
Description
Technical field
The present invention relates to a kind of lawver total man worker Ecological Control nature raising technology.
Background technology
Lawver is the unique fresh water kind of rockling, also is the rockling that contains cod-liver oil in the freshwater fish in unique liver, is the peculiar fish of China, the liver delicious flavour, and its nutrition and economic worth are all very high, and it originates in basin, Xinjiang of China Eerqisihe River.In recent years because taking place frequently of overfishing and natural calamity makes that these species are endangered.Be the distinctive cold water fish resource of protection this China of lawver, Xinjiang Production and Construction Army Corps begin to carry out the research of lawver raising technology, have obtained certain progress at present, but the technology of having grasped still can not realize total man worker from numerous self-fertile.Fish for suitable parent population mating season from Eerqisihe River, process is injected oxytocic drug stimulates parent population to lay eggs, and fertilized egg obtains newly hatched larvae through hatching in two months, and ground temperature is low owing to working as, and natural bait lacks, so the survival rate of prelarva is very low.
Summary of the invention
The purpose of this invention is to provide a kind of cost low, simple to operate, to parent population damage the little and high lawver total man worker Ecological Control nature raising technology of parent population survival rate in postpartum.
Key of the present invention has 2 points: the one, according to its natural propagation condition, the lawver parent population is carried out long-term low temperature cultivation in winter, otherwise the parent population sexual gland can not be reached maturity; The 2nd, the natural spawning condition of simulation lawver, increased water flow behind the lawver gonadal maturation stimulates parent population to oestrus and lays eggs.
Particularly, method of the present invention may further comprise the steps:
(1) parent population screening
Autumn, the lawver adult fish of culturing more than 3 years is screened, select that individuality is big, physique is healthy and strong, the undamaged lawver adult fish of body surface is used parent population as laying eggs;
(2) autumn reinforced cultivating
Parent population is put into the parent fish rearing pond carry out the reinforced cultivating in autumn, cultivation density is 2 ~ 3 tails/m
2, 8 ~ 15 ℃ of water temperatures, outdoor flowing water is cultivated, and the place of having a rest for the parent population lucifuge is set at the bottom of the pond, and the bait of parent population reinforced cultivating is for being fit to the higher small-sized wild fishes of carp, crucian carp and some nutrition of bore, and feeding volume is 3% ~ 5% of a parent population body weight, and throw something and feed every day at dusk.
(3) winter low temperature is cultivated
Move into spawning pond with parent population and carry out the winter low temperature cultivation winter, and cultivation density is 2 ~ 3 tails/m
2, female-male proportion is 1:2, outdoor flowing water is cultivated, reduce water and flow to the water surface and freeze, at the bottom of the control pond water temperature in 0 ~ 4 ℃ of scope, the bait that the lawver winter low temperature is cultivated and throw something and feed mode with autumn reinforced cultivating identical;
(4) simulating natural condition stimulates parent population to lay eggs
After trimestral low temperature cultivation, increased water flow removes the smart ovulation of surperficial ice sheet stimulation parent population row, is provided with at delivery port to collect ovum basket collection fertilized egg;
(5) incubating oosperm
The fertilized egg of collecting is moved into flowing water hatching in the incubation equipment, and be fertilized egg to gastrul stage about 25 ~ 30 days early stage, and incubation temperature is controlled at 0 ~ 2 ℃, and the later stage is the primitive gut later stage to about 15 ~ 20 days of rupture of membranes, and incubation temperature is 2 ~ 5 ℃, and brooding time is 40 ~ 50 days.
The beneficial effect that the present invention obtains is: adopt raising technology result of the present invention to show, the lawver prelarva of introducing from Xinjiang was through the breed in 3 years, body weight reaches 0.5 kg ~ 1 kg, and sexual maturity therefrom filters out 60 rauns, 120 milters as the parent population reinforced cultivating.Spring in 2008 stimulated parent population to lay eggs with ecological method, and 15 lawver parent populations lay eggs and obtain 1,200,000 fertilized eggs, obtain newly hatched larvae 400,000 tails altogether through bimestrial hatching.50 female parent populations of lawver laid eggs in 2009, obtained 1,000 ten thousand in fertilized egg altogether, obtained newly hatched larvae 2,400,000 tails after the hatching.The present invention is the artificial breeding technology that is fit to lawver, have cost low, simple to operate, to the parent population damage very little and postpartum parent population the high characteristics of survival rate, and the present invention is less demanding to cultivating condition and technical level of operators, is easy to popularize.
