Abstract
The invention discloses an artificial breeding method for paddlefish. After fertilized eggs stand for a moment by the aid of artificial semen collection, artificial incubation and incubation management, the fertilized eggs are cleaned up with water, fish eggs are slowly added and gently stirred while pouring, the fertilized eggs are washed out and placed into an incubator for incubation after all the eggs are scattered and granular and no longer cake when standing, new water is immediately poured into an incubation cylinder after the fish eggs are placed into the incubation cylinder, bolting silk needs to be frequently washed and filtered in the incubation process, and an appropriate amount of fungicide is added for treatment until incubation is finished. The breeding method is high in breeding rate, survival rate and disease resistance.
Description
Technical field
The present invention relates to technical field of aquaculture, specifically the artificial fecundation method of paddlefish.
Background technology
Paddlefish cries again duckbilled sturgeon, is a kind of large-scale precious economic fish of fresh water of the original U.S..Equal energy normal existence under 0-37 ℃ of water temperature, feeding habits are similar to bighead, and cost is lower, grows very rapid, easily fishes for, and ovum, meat, leatherware have high economic worth, are to adjust structure in current aquaculture, increase one of improved seeds of fisherman's income.
Summary of the invention
The object of this invention is to provide the artificial fecundation method of a kind of paddlefish of high yield.
Technical scheme of the present invention is achieved in that the artificial fecundation method of paddlefish, and step is as follows:
1) artificial semen collection: fish is carried away to pond with stretcher, extruding belly both sides, anus front, seminal fluid just can flow out, the container access of available sterilization is stand-by, former seminal fluid is added to seminal fluid and preserve liquid, the sealing test tube shaking up after dilution is placed directly in refrigerating box, or fills in the vacuum flask of ice cube, temperature remains between 1-5 ℃, and the ratio of former seminal fluid and preservation liquid is 1:10; At the in-built a small amount of clear water of washbowl, everyone respectively holds tail raun or a milter, ovum and seminal fluid is clamp-oned in basin respectively simultaneously, and with stirring gently, smart ovum is fully mixed, and then adds water and stirs 1-5 minute;
2) artificial incubation: fertilized egg is in a moment standing, and water cleans up fertilized egg, slowly adds fish-egg to stir gently while arriving, and when whole ovum grains are discrete particles shape, after no longer luming, fertilized egg is rinsed well when standing, puts into incubator and hatches;
3) hatching management: fish-egg injects new water after putting into hatching cylinder immediately, will often scrub filtration bolting silk in hatching process, adds appropriate fungicide processing, until complete hatching.
Described preservation liquid is sodium chloride 5g, potassium chloride 12g, calcium chloride 0.7g, sodium bicarbonate 4g, glucose solids 2 and pure water 1500mL.
More than in hatching management, every premium on currency dissolved oxygen amount remains on 6-8mg, the inclined to one side alkalescence of water.
Mating system reproduction rate of the present invention is high, and survival rate is high, and resistance against diseases is strong.
Embodiment
The artificial fecundation method of embodiment 1 paddlefish, step is as follows:
1) artificial semen collection: fish is carried away to pond with stretcher, extruding belly both sides, anus front, seminal fluid just can flow out, the container access of available sterilization is stand-by, former seminal fluid is added to seminal fluid and preserve liquid, and the sealing test tube shaking up after dilution is placed directly in refrigerating box, or fill in the vacuum flask of ice cube, temperature remains between 1-5 ℃, and the ratio of former seminal fluid and preservation liquid is 1:10, and described preservation liquid is sodium chloride 5g, potassium chloride 12g, calcium chloride 0.7g, sodium bicarbonate 4g, glucose solids 2 and pure water 1500mL.At the in-built a small amount of clear water of washbowl, everyone respectively holds tail raun or a milter, ovum and seminal fluid is clamp-oned in basin respectively simultaneously, and with stirring gently, smart ovum is fully mixed, and then adds water and stirs 1-5 minute;
2) artificial incubation: fertilized egg is in a moment standing, and water cleans up fertilized egg, slowly adds fish-egg to stir gently while arriving, and when whole ovum grains are discrete particles shape, after no longer luming, fertilized egg is rinsed well when standing, puts into incubator and hatches;
3) hatching management: fish-egg injects new water, more than every premium on currency dissolved oxygen amount remains on 6-8mg in hatching management after putting into hatching cylinder immediately, the inclined to one side alkalescence of water, in hatching process, to often scrub filtration bolting silk, add appropriate fungicide processing, until complete hatching.
Mating system reproduction rate of the present invention is high, and survival rate is high, and resistance against diseases is strong.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
