Description
Technical field
The invention belongs to freshwater aquiculture technical field, and in particular to a kind of cultural method for improving young leech survival rate.
Background technology
Leech growth and breeding in the freshwater of inland, is the traditional extraordinary medicinal aquatic animal in China, its dried product big gun
The traditional Chinese medical science is used as medicine after system, has treatment apoplexy, hypertension, dredging, amenorrhoea, traumatic injury and other effects, newfound leech preparation exists
Prevention cardiovascular and cerebrovascular disease and anticancer aspect have special efficacy, it is in history based on fishing naturally, in recent years, because of environmental pollution plus
Play, wild natural resources fall sharply, and with the deep development of leech medical value, there is a huge market demand potential for it, before hirudiniculture
Scape is good, and a great problem of the cultivation of leech is exactly the raising of young leech, the survival rate of young leech in the breeding process of existing children leech
Below 20%, therefore, it is necessary to the breeding method to young leech further to study.
The content of the invention
The purpose of the present invention is for it is existing the problem of, there is provided a kind of cultural method for improving young leech survival rate.
The present invention is achieved by the following technical solutions：A kind of cultural method for improving young leech survival rate, including into
Cultivation in the babinet of the mouth of a river and water outlet, the babinet is interior to be equipped with the string bag, and multiple sealing mesh bags are fixedly connected with the string bag, described close
Installing Chinese prickly ash stalk crushed material, the babinet temperature-adjustable and oxygen content, specifically include following steps in block bag：
（1）Hatch young leech after the kind leech for choosing health is bred according to a conventional method, young leech is put into babinet, is set at this time in babinet
It is 32-34 DEG C of mixed liquor to have temperature, and the oxygen content of the mixed liquor be 28-32mg/L, included in the mixed liquor dimethyl-
β-acetic acid thetin 0.2-0.4wt%, sodium molybdate 0.1-0.2wt%, lignin 2-4wt%, catalase 0.04-0.08wt%；
（2）Cultivated 1-3 days in young leech, the temperature of temperature mixing liquid is 32-34 DEG C in babinet, and the oxygen content of mixed liquor is 28-
32mg/L, at this stage, replaces in babinet 30% mixed liquor daily；Cultivated 4-20 days in young leech, temperature mixing liquid in babinet
Temperature is 24-26 DEG C, and the oxygen content of mixed liquor is 26-28mg/L, 50% mixed liquor in every 5 days replacement babinets；Cultivated in young leech
21-60 days, the temperature of temperature mixing liquid was 28-32 DEG C in babinet, and the oxygen content of mixed liquor be 28-30mg/L, every 3 days replacement casees
Internal 50% mixed liquor；After young leech cultivates 60 days, the temperature of temperature mixing liquid is 22-27 DEG C in babinet, and mixed liquor contains
Oxygen amount is 28-30mg/L, replaces 20% mixed liquor daily；
（3）Young leech was taken out using the string bag every 10 days, replaces the string bag and the sealing mesh bag equipped with Chinese prickly ash stalk crushed material, and it is right
Box house carries out cleaning and sterilizing.
As further improvement of these options, the volume of the babinet is 1-1.5m3, depth of water 80-100mm.
As further improvement of these options, the volume accounting in every cubic metre of the Chinese prickly ash stalk crushed material
For 4-8%.
As further improvement of these options, the Chinese prickly ash stalk crushed material is before use to be dried to water content low
In 2%, drying temperature is 80-90 DEG C.
As further improvement of these options, the injected volume of young leech is 110-120 in the babinet every cubic metre described
Tail.
Conventionally fed after young leech is launched three days.
The present invention has the following advantages compared with prior art：By setting babinet to cultivate young leech in the present invention, make young leech
Breeding environment be easy to control, compared with prior art, initial stage, the temperature of mixed liquor was higher, in mixed liquor and highdensity bar
It can aid in raising under part and promote leech movement, make its activity preferably, contribute to its healthy growth；Chinese prickly ash stalk crushed material
Mixed liquor can be played further quenched effect by setting, and coordinate mixed liquor to cultivate young leech, keep the growth of young leech to be good for
Health, under the conditions of same feeding can quickly, the growth of health, improve the survival rate of young leech, it is high to cultivate leech regularity,
Cultivating condition is simply controllable, suitable for promoting the use of.
