Abstract
The invention discloses a feeding method for dispersing gregarious leech larvae. According to the method, small paludina in rural rice fields is adopted as a larva support feed of leech larvae, so that the condition of severe death caused by that fact that in the past, gregarious and clustered phenomena of the larvae are serious and the feed cannot be taken is solved thoroughly. The method has a simple and practical technology, and has the advantages that the phenomena of water pollution and severe deaths due to traditional paste feeding are changed, meanwhile, the small nutrient paludina is adopted to feed the leech larvae, and particularly, the leeches have good liveness, grow fast and are extremely low in death rate; and the method is not used by anyone domestically, the worries that the gregarious leeches do not eat and the death is severe are solved thoroughly during the future cultivation process of wide cultivation lovers, and the method can be widely applied to application and development by cultivation enterprises and farmers in production.
Description
Technical field
The invention belongs to a kind of cultural technique, specifically a kind of gregarious raising method of leech seedling that disperses.
Background technology
China is engaged in hirudiniculture production, slower development in a lot of areas, and the basic of problem is exactly to feed the phase seedling, and lethality is high, survival rate is less than 30%, main cause, just climb immediately heap, live in groups and do not take food as long as leech enters water body large or small, and this phenomenon is the life habit that it can't change.And traditional seedling raising method, stereotyped is all to use freshwater mussel, spiral shell pulverizes the meat paste and adds other batching, thereafter, the feed of processing is placed on the work stone platform, allow it oneself take food, people know, seedling one enters in water, about one minute, all be gregarious on the surrounding pool wall, in three days, reliable self yolk sustains life, after three days, will body colour turn black if sucked not in time, progressively dwindle, slowly disappear, this injures and deaths can't be calculated, particularly the meat paste of processing is fed seedling, not only time-consuming, very serious to water pollution, temperature one rises, water body will turn green blackout, as replacement water not in time, the children leech is very fast dead.
Summary of the invention
The purpose of this invention is to provide a kind of gregarious raising method of leech seedling that disperses, feed young leech and disperse fast the gregarious flow and method of young leech with little river snail, effect is fine, very successful.
Technical scheme of the present invention is as follows:
The present invention has changed the paste of traditional processing and has fed polluted water, the serious phenomenon of injures and deaths.Adopt little river snail to feed young leech, climb heap by little river snail, be gathered in around each young leech, make young leech can not assemble, conveniently take food, nutrition is very abundant, particularly active good, growth is fast, casualty rate is extremely low, without anyone is practical, crosses this method at home, and this will be to vast cultivation fan in breeding process from now on, solved fundamentally that seedling is gregarious does not suck dead serious trouble and worry, and can be widely used in breeding enterprise and raiser's applicating and exploitation aborning.
Embodiment
A kind of gregarious raising method of leech seedling that disperses:
1, layout environments.the leech seedling goes out cocoon generally five, June, also I transplant seedlings season in regional rural area just, we find in the rice seedling bed, rural area to occur the little river snail of some mung bean shape sizes, it to climb the gregarious life habit of heap fully similar to the leech life habit, thereby, the present invention takes mutually gregarious, climbing simultaneously heap " one to one " complementarity method feeds, concrete grammar: the one, go out the cocoon seedling and enter strict sterilization in the forebay, pond, change fresh water, 25 centimeters of the depth of waters are advisable, pool wall surrounding top is concordant with the water surface, put the green vegetations such as weter hyacinth or pasture and water, general by 20 centimeters wide getting final product of wall (must be fixing with bar or rope), seedling water once like this, vegetation has formed separation net, little seedling greatly reduces to the gregarious probability of climbing heap of wall.The 2nd, high temperature season, pasture and water can be blocked again the direct irradiation of solar glare to seedling.Three have been to provide the good condition that young leech has a rest, takes food, and have also purified water quality simultaneously.
2, choose feed.Before the children leech enters pond, after the little river snail that rice seedling bed is fished for is rinsed sterilization well, evenly throw in foodstuff " little river snail ", every square 5000-6000 tail seedling along surrounding vegetation blade top, can throw in 5000 grams (maintenance dose 3 days), so little river snail climbs heap in advance on pool wall and pasture and water, after seedling enters pond, be gregarious in together thereupon, little river snail is close to little seedling health, and (little river snail grain is little, quantity is many), ring of encirclement of self-assembling formation, so the seedling of one of percentage hundred can enough suck little spiral shell alive.Two days later, little seedling is united and takes food in rapid succession, and testing for many years survival rate can reach more than 98%.
Its advantage of the method: 1, fundamentally solved seedling and lived in groups and get less than the dead serious difficult problem of foodstuff.2, seedling is fed saving of work and time, simple to operate.3, granular little river snail can the polluted water environment after entering water body.4, after seedling sucks, nutritious, immunity strengthens, and traditional meat pasty state foodstuff is perishable to rot, and young leech is several exhales that all to suffer from the sick injures and deaths of enteron aisle serious.5, growth is fast, and active good, tradition is fed seedling and needed about 25 days, just can grow to 6-7 centimeters, and the method only needs 10 day time, just can grow to fast 7-8 centimeters.After 15 days, just can divide pond to raise, therefore, adopt little river snail feeding effect good, very successful.
Claims (1)
1. one kind is dispersed the gregarious raising method of leech seedling, it is characterized in that comprising the following steps:
(1), the leech seedling enters strict sterilization in the forebay, pond, changes fresh water, depth of water 25-30 centimetre is advisable, pool wall surrounding top is concordant with the water surface, along the pool wall surrounding, put the green vegetations such as weter hyacinth or pasture and water, generally by 20 centimeters wide getting final product of wall, must be fixing with bar or rope;
(2), before the leech seedling enters pond, after the little river snail that rice seedling bed is fished for is rinsed sterilization well, evenly throw in foodstuff " little river snail " along surrounding vegetation blade top, every square of water surface can be thrown in 5000-6000 tail water leech seedling, so little river snail climbs heap in advance on pool wall and pasture and water, after seedling enters pond, be gregarious in together thereupon, little river snail is close to little seedling health, little river snail grain is little, quantity is many, ring of encirclement of self-assembling formation, and seedling just can enough suck little river snail.
