Abstract
A method for increasing survival rate of autumn juvenile leech is characterized in that the cast juvenile leech are different in size, leech larvae are sorted out and put into an intensive culture pool for culturing, the intensive culture pool is formed by putting up a greenhouse on an existing pool and adding heating lamps, so that the leech larvae can safely pass the winter, and the growth of the leech larvae is promoted, wherein the greenhouse is made of vinyon, the heating lamps are infrared lamps, and the temperature in the intensive culture pool is kept to be above 20 DEG C, and ventilation is performed properly. By adopting the method disclosed by the invention, the growing speed of the leech can be effectively enhanced, the death rate of the leech larvae is reduced, the survival rate of the juvenile leech is improved, and the leech yield is increased.
Description
Technical field
The present invention relates to the aquaculture field, particularly relate to a kind of method that improves leech autumn shoot survival percent.
Background technology
Leech, the popular name leech, growth and breeding in the freshwater of inland, be the traditional extraordinary medicinal aquatic animal of China, after its dried product is concocted, the traditional Chinese medical science is used as medicine, and has the effects such as treatment apoplexy, hypertension, the clear stasis of blood, amenorrhoea, traumatic injury.In recent years new discovery leech preparation has special efficacy at control cardiovascular and cerebrovascular disease and anticancer aspect.It is in history naturally to fish for as main, and because of the abuse such as agricultural chemicals, chemical fertilizer in recent years, and industrial or agricultural " three wastes " is to the pollution of environment, and wild natural resources falls sharply, and along with the deep development of leech medical value, its market demand potential is huge.Southern china before and after nineteen ninety-five, starts to fish for the nature seed, carries out first artificial feeding, succeeds.Northern area does not have cultivation because of seed and technical reason always.
Summary of the invention
Leech below 15 degrees centigrade the time, enters semidormancy, no longer takes food in the time of below 10 degrees centigrade, and the putting 1 year two season of seedling of leech, being once April, is once September, the leech of throwing seedling September, to face in the situation of passing the winter, this moment, seedlings can be passed the winter, and some can't pass the winter safely seedling.But seedlings when passing the winter due to dormancy and stop the feed, also cause the growth stop.
The purpose of this invention is to provide a kind of method that improves leech autumn shoot survival percent, the leech seedling is sorted out and puts into the intensive culture pond and cultivate, and described intensive culture pond is: build booth on pond, described booth, its booth apogee distance pond is 2-3 rice, and the interior span of its booth is 3-6 rice; Described booth material is vinyon; Be provided with heating lamp or floor heating in described booth, temperature in its intensive culture pond is remained in 20-25 ℃ of scope.
The method of the invention can effectively strengthen the growth rate of leech autumn seedling, reduces the lethality of leech seedling, improves the survival rate of leech seedling, promotes leech output.

Specific embodiment
A kind of method that improves leech autumn shoot survival percent, the leech seedling is sorted out and puts into the intensive culture pond and cultivate, and described intensive culture pond is: build booth 1 on pond, described booth 1, its booth 1 apogee distance pond 2 is 2.5 meters, and the interior span of its booth 1 is 6 meters; Described booth 1 material is vinyon; Be provided with heating lamp 3 in described booth 1, temperature in its intensive culture pond is remained in 25 ℃ of scopes.
A kind of method that improves leech autumn shoot survival percent, sort out the leech seedling to put into the intensive culture pond and cultivate, and described intensive culture pond is: build booth 1 on pond, and described booth 1, its booth 1 apogee distance pond 2 is 2 meters, the interior span of its booth 1 is 3 meters; Described booth 1 material is vinyon; Be provided with heating lamp 3 in described booth 1, temperature in its intensive culture pond is remained in 20 ℃ of scopes.
