Description
Technical field
The invention belongs to the biological technical field of cultivating, relate in particular to the simple and easy method of a kind of mass purification wheel animalcule.
Background technology
In the cultivating process of fry; The live body wheel animalcule is the indispensable animal bait of postlarva; Enlarge in the cultivating process, need the bigger pure wheel animalcule of relative quantity, need a large amount of pure wheel animalcules to throw something and feed as the provenance (underlying group) of wheel animalcule expansion cultivation or in fry rearing wheel animalcule.
At present, carry out the provenance source that wheel animalcule enlarge to cultivate three kinds of approach are arranged.
The one, carry out the wheel animalcule monoclonal: under the laboratory condition, single wheel animalcule is selected, put into one by one in the small container of 50mL triangular flask and cultivate at microscopically.Needed 10 days to 30 days or cultivation (one-level cultivation) for more time.The wheel animalcule that monoclonal cultivates also need pass through intermediate rearing (secondary cultivation) and arrive yielding ability expansion cultivation (three grades of cultivations) again.In these three breeding phases, the provenance in each stage (underlying group) lazy weight will obtain the big cultivation colony of quantity and need pass through the long time.
The single-stage wheel animalcule cultivation time is long, must receive protozoa or scratch the pollution of foot type, finally leads to the failure and can not obtain a large amount of pure wheel animalcules.To the wheel animalcule requirement that satisfies the fry large-scale production, wheel animalcule monoclonal to wheel animalcule large-scale production just approximately needs 2 months to 3 months time from monoclonal.This mode success rate is low, time-consuming, effort, efficient are low.
The 2nd, buy the wheel worm's ovum and hatch and obtain.1. this approach exists buys difficulty, and most breed dealers do not know manufacturer; 2. cost an arm and a leg, cost is high; 3. take turns worm's ovum and exist incubation rate low sometimes, cost performance is low; 4. purchase wheel animalcule incompatibility local environment, cause introducing a fine variety failure, have a big risk.
The 3rd, directly make a big purchase in large quantities or fish for: no matter be the wheel animalcule of making a big purchase in large quantities or fishing for, be the free wheel worm after outdoor production is collected at present, mixing usually has nematode, scratches foot type adult and scratches the foot type six limb young, the shrimp young, assorted shrimp, protozoa etc.
The bulk purchase wheel animalcule has part or most of dead after long-distance transport, can not directly throw something and feed to postlarva as the erbium material, more unsuitablely directly enlarges the provenance of cultivating as yielding ability.1. these wheel animalcules contain various protozoas and scratch sufficient type, and 2. the packed and transported time is unsuitable long; Every bag of Packing Unit is little, and the long-distance transportation cost is high, and 3. survival rate is not high, and the above transportation survival rate of temperature 25 degree is lower; 4. environmental suitability is poor.
Want to obtain comparatively difficulty of the pure wheel animalcule of live body in enormous quantities aborning.
The one, the physical filtering separation difficulty: the individuality big with the wheel animalcule individual difference can be able to filter through screen cloth.The same with wheel animalcule size perhaps than protozoas such as the little individuality of wheel animalcule such as some duricrust worms, just is difficult to be added on filter and has distinguished.
The 2nd, drug effect and separation difficulty: wheel animalcule belongs to shell-fish with scratching the foot class, requires medicine to have the selection property to similar xenogenesis.A lot of medicines comprise wheel animalcule interior all kill or can only partly kill other mix polypide, or wheel animalcule is killed and other polypides are not killed, also just can not reach the purpose of purifying wheel animalcule.
At present in secondary, three grades of wheel animalcules are cultivated; Owing to have no idea to obtain the pure wheel animalcule underlying group of q.s; Cause the scale fry to produce required wheel animalcule and can't realize that cause survival rate to reduce significantly thereby cause hatching not have a large amount of wheel animalcules to ingest, the scale fry produces and can not carry out.In the production of seawater fry, show especially outstandingly.
