Background technology
Bay scallop (Argopecten irradias), belongs to Mollusca, lamellibranchiata, and Anisomyaria, Pectenidae, scallop belongs to, and originates in U.S., Atlantic bank.Nineteen eighty-two is introduced China, and carries out artificial breeding and cultivation.Bay scallop is formed then, the high-quality mariculture kind that results are then a kind of strong adaptabilities, growth is fast, the culture-cycle is short, disease is few, output is high.Bay scallop meat flavour is delicious, is of high nutritive value, and is rich in protein multivitamin and trace element, is a kind of low calorie, high protein, can prevent and treat the ultimate food of middle-aged and old chronic diseases, is to be also subject to most one of aquatic products that the common people welcome.The processing and utilization rate of bay scallop is very high, and almost whole body has use value, and market demand is very big.
The seed of Bay Scallop Argopecten Irradians Cultured is all by the indoors artificial acquisition of growing seedlings.Bay scallop grow seedlings be in the commodity shellfish of the previous year cultivation selective advantage individuality as kind of a shellfish, annual late January takes kind of a shellfish into cultivation pond, workshop, heat up, rich bait, flowing water cultivate 45～50 days, treat that sexual gland ripe arrangement that reach full growth lay eggs, through hatching, larva cultivation, settlement and metamorphosis and juvenile mollusk, cultivate, go out pond, the middle ten days upper April keeps a full stand of seedings, forms to outdoor, and late October to late November gathers in the crops.
Kind shellfish lays eggs, hatches is most critical and important link in bay scallop seedling raising process, obtains enough and healthy D shape larva, is the basis that bay scallop is grown seedlings.Bay scallop is hermaphroditism, in seawater, lay eggs, ejaculation, millions of of kind shellfish ovulation, sub tens of ejaculation, and ovum only and a sperm in conjunction with forming fertilized egg, the sperm that all the other are a large amount of and the metabolite of laying eggs will be pulled out from spawning pond, otherwise, dead in several hours, cause spawning pond ammonia nitrogen sharply to raise, hatching water quality is ruined, embryo development procedure can not continue, and directly affects the survival of incubation rate and larva, has reduced incubation rate.So, after the end of laying eggs, to pull as early as possible the ovum of unnecessary sperm, the metabolite of laying eggs, immature fragmentation etc. out, this process is called washes ovum.
At present, the conventional ovum method of washing is: with aerating machine, to hatchery, inflate, make the formation foams such as sperm, and arrange the hand-held water-mixing plate of several workmans to stir hatchery crystal's liquid and the metabolite of laying eggs formation foam, foam is copied and pulled out with bolting silk net, this method time is long, need that workman is many, labour intensity is large, and easily because skimming not in time and thoroughly do not cause incubation rate decline.
The spawning pond of 20 cubes of water bodys, 4 workmans need to wash ovum 1～1.5 hour.The cultivation workshop of 1000 cubes of water bodys, once can have 30 above spawning ponds to lay eggs, and needs 20 multiplex (MUX) people, washes ovum more than 10 hours, and its labour intensity is high, and efficiency is low, affects incubation rate, when incubation rate is below 10%, can cause larger economic loss.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of technique simple, easy to operate, wash ovum effective, and cost low energy improves the method that bay scallop is washed ovum efficiency.
The technical solution used in the present invention is: a kind ofly improve the method that bay scallop is washed ovum efficiency, it is characterized in that: the size of selecting immersible pump according to the size of spawning pond; Tank is arranged on the centre position in workshop; Determine that the length of pipe that connects immersible pump is for reaching the length of spawning pond in workshop; On the delivery port of immersible pump, connect the pvc pipe of 20～30 centimeter length, the termination of pvc pipe mouth is " duckbilled " shape, and the gap of " duckbilled " mouth is 0.5～0.7 centimetre; Immersible pump effluent pipe mouth is 40～60 centimetres from the height of the spawning pond water surface; With immersible pump, extract in tank through the seawater of sand filtration and cotton bag filtration, ocean temperature is 25～28 ℃, and the immersible pump mouth of pipe is 45～60 degree angle spawning ponds baths; With water-mixing plate, stir up and down the water in spawning pond, make seminal fluid and the metabolite of laying eggs form rapidly foam; With bolting silk net, pulling foam out completes and washes ovum operation.
Technique of the present invention is simple, easy to operate, cost is low, and labour intensity is low, and operating efficiency is high, washes ovum effective, can improve the incubation rate of bay scallop fertilized egg, and incubation rate can reach 30～60 ﹪, makes to grow seedlings to reach the level of high and stable yields.
