Abstract
A method to killing copepod in Rotifer culture relates to bait applicator culture aimed at solving the problem of killing copepod in Rotifer culture. The technology program of the invention includes: equipping inflatable stone in the pool, injecting seawater and seawater Chlorella, it is characterized by equipping inflatable stone in the pool by one/ m2, injecting seawater and seawater Chlorella by3:1 to 4:1, the salinity of mixed seawater is 15-20%., the rotifer asylum density is 1000-1500/ml, the water temperature is 25-30degreeC, pouring the anthon solution into the pool by the density of 1.2g/m3, collecting the rotifer using the 250 mesh sieve silk bags after 24 hours and maintaining inflatable in the rotifer process. The invention applies to the bait applicator culture of fish, shrimp, crab seed.
Description
Technical field:
The present invention relates to food organisms cultivates.
Background technology
Wheel animalcule have individual little, the speed of moving about is slow, the advantage of prey is fish, shrimp, the desirable open-mouthed bait of juvenile crab kind easily.The seed wheel animalcule required time length of throwing something and feeding is different according to kind, generally behind opening 5-15 days, if the copepoda that this stage is mingled in the wheel animalcule is not removed, make it enter Miao Chi with wheel animalcule, the mobility of copepoda is better than wheel animalcule, copepoda strives bait with seed, strives the space in the seedling pond, and seed can't prey on copepoda in the initial stage of growing seedlings, some carnivorous copepoda even also can prey on nauplius and the wheel animalcule of the microcrustacean in the seedling water.In carrying out mud crab seedling production process, as the wheel animalcule that will thoroughly the not remove copepoda juvenile crab of throwing something and feeding, the promptly a large amount of breedings of copepoda after 7-10 days cause the artemia nauplii of juvenile crab to be killed in several hours or to prey on, and making grows seedlings produces and can't normally carry out; In the wheel animalcule incubation, a large amount of breedings of copepoda are to cause wheel animalcule to cultivate the one of the main reasons of failure, and therefore, the copepoda of removing in the wheel animalcule cultivation has bigger meaning for stablizing seed production.In fish, shrimp, the production of crab seedling, adopt net to filter the copepoda that is mingled in the wheel animalcule at present, promptly select mesh to be a bit larger tham the filtering mesh bag of wheel animalcule, the wheel animalcule of the Miao Chi that throws something and feeds or the wheel animalcule of preparing to inoculate are carried out sieving, the disadvantage of this kind method is to remove the individual size copepod larva close with wheel animalcule, cultivates for seed rearing and wheel animalcule and stays hidden danger; In the sieving process, also, wheel animalcule density height, mesh cause the dead and waste of wheel animalcule owing to stopping up.
Summary of the invention
The present invention need solve the problem of killing copepoda in the wheel animalcule cultivation.
Technical scheme of the present invention is included in to be provided with in the pond injects seawater and marine chlorella in gas charging stone, the pond, it is characterized in that in the pond by 1/m
2Gas charging stone is set, injects seawater and marine chlorella in 3: 1 to 4: 1 volume ratios, the seawater salinity 15-20 ‰ behind the mixing, wheel animalcule is accommodated 1000-1500/ml of density, and water temperature is controlled at 25-30 ℃, by 1.2 gram/m
3Concentration splashes into the pond after with the chlorophos dissolution of crystals, collects wheel animalcule with the 250 mesh sieve thin,tough silk bag of gathering after 24 hours.
Because the chlorophos crystal that the present invention uses is a kind of common pesticides, produce a kind of inhibitor of cholinesterase behind the chance water, wheel animalcule is at 5 gram/m
3Under the chlorophos concentration conditions, still can normally survive after 96 hours; And copepoda is at 0.5 gram/m
3Under the chlorophos concentration conditions, promptly all dead after 24 hours, utilize wheel animalcule and copepoda to the anticholinesterase sensitivity difference, can reach the purpose of thoroughly killing copepoda with a spot of chlorophos in the short period of time, and do not influence the growth of wheel animalcule, compare with the net filtering method with original, have cost low, to wheel animalcule damage less, the medicament residue phase is short, to the people, animal low toxicity, and reduce the advantage of labour intensity.
Embodiment
This method is pressed 1/m in cement pit or resin tank
2Gas charging stone evenly is set, injects seawater and marine chlorella in 3: 1 to 4: 1 volume ratios, the seawater salinity 15-20 ‰ (gram/kilogram) behind seawater and the marine chlorella mixing accurately measures effective water body in the pond, by 1.2 gram/m before the medication
3Concentration evenly splashes into the pond after with the chlorophos dissolution of crystals, wheel animalcule is accommodated density and is controlled at 1000-1500/ml, cultivate water temperature and be controlled at 25-30 ℃, after the medication 24 hours, because the copepoda that is mingled in the wheel animalcule is thoroughly killed, the bag of gathering that 250 mesh sieve thin,tough silk of 40 centimetres of available diameters, 2 meters of length are made discharges water from the wheel animalcule culture pond and collects wheel animalcule;
Remain inflation in the wheel animalcule processing procedure, aeration quantity is wavy with the water surface and is advisable; When gathering, wheel animalcule must notice that flow velocity is not too fast, death in order to avoid wheel animalcule is hit;
Can and kill two steps of copepoda and carry out together fortification the wheel animalcule of preparing to throw something and feed, not only improved wheel polypide inner height unsaturated fatty acid content, growth of seedlings is grown favourable, before throwing something and feeding with the wheel animalcule of collecting with clean seawater rinsing, removal medicament residue.
The mode that adopts two ponds to use in turn in process of production is to guarantee all to have every day through fortification and to kill the high-quality wheel animalcule supply seedling pond that copepoda is handled.
Claims (3)
1. kill the method for copepoda during wheel animalcule is cultivated, be included in to be provided with in the pond and inject seawater and marine chlorella in gas charging stone, the pond, it is characterized in that in the pond by 1/m
2Gas charging stone is set, injects seawater and marine chlorella in 3: 1 to 4: 1 volume ratios, the seawater salinity 15-20 ‰ behind the mixing, wheel animalcule is accommodated 1000-1500/ml of density, and water temperature is controlled at 25-30 ℃, by 1.2 gram/m
3Concentration splashes into the pond after with the chlorophos dissolution of crystals, collects wheel animalcule with the 250 mesh sieve thin,tough silk bag of gathering after 24 hours, keeps inflation in the wheel animalcule processing procedure.
2. the method for killing copepoda in wheel animalcule is cultivated according to claim 1 is characterized in that killing copepoda and fortification and carries out together.
3. the method for killing copepoda in wheel animalcule is cultivated according to claim 1 is characterized in that and will collect wheel animalcule with clean seawater rinsing.
