Abstract
The invention relates to a breeding method for leeches, which comprises the following steps of digging a pond; utilizing cage culture in the pond; keeping the pH (Potential Of Hydrogen) of water in the pond at 6-8; selecting 120-150 pieces per kilogram parent leeches; putting into the parent leeches in the early spring; mainly taking spiral shells as the baits for the leeches, feeding and then breeding; feeding 20-30 kilograms spiral shells per mu; feeding animal blood for one time per week; keeping the water temperature for breeding at 10-35 DEG C by exchanging water during the breeding process before winter comes; when winter is coming, draining water and then covering with grass, keeping soil wet and enabling the leeches to overwinter in the soil or adding water in the pond for preventing the water in the pond from being frozen to the bottom. According to the method provided by the invention, the design is reasonable, the operability is strong and the survival rate of the bred leeches is high; the cage culture is adopted for the breeding for the leeches according to the method provided by the invention; according to the method, the fishing and catching are convenient; the breeding condition is flexibly mastered during a breeding process; the breeding yield is increased and the breeding benefit is obvious according to an effective breeding method.
Description
Technical field
The present invention relates to a kind of cultural method of aquatic products, particularly the cultural method of a kind of leech.
Background technology
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides the cultural method of the leech that a kind of method is reasonable, survival rate is high, controllability is strong, output is high.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is the cultural method of a kind of leech, is characterized in, its step is as follows:
(1) construction in pond: excavation pond, utilizes cage culture in pond; Net cage adopts 40 order nets to make the purse seine exceeding the water surface more than 1 meter, and the pond depth of water is retained to few 60 centimetres, and the pH of pond water is at 6-8;
(2) plant the selection of leech and input: selects that healthy and strong nothing is hindered, 120-150 bar/kilogram kind leech; Drop into kind of a leech during early spring, every mu of water surface breeding density is 18-22 kilogram;
(3) aquaculture management: leech bait, based on spiral shell, is bred after throwing something and feeding voluntarily; Spiral shell feeding volume to be thrown something and fed 20-30 kilogram with every mu of water surface; To throw something and feed weekly animal blood 1 time simultaneously; In feeding process before entering winter, keep temperature of cultivation between 10-35 DEG C by changing water; Come interim in the winter time, water is discharged dogstail on bonnet, keep that earth is moistening allows leech pass the winter in earth, or add the water in swimmer's pool pond, prevent Chi Shui to be frozen into the end.
The cultural method of leech of the present invention, further, in step (1): preferably the rich water transparency of pond water is at 20-30 centimetres.When rich water transparency height, execute feces of livestock and poultry 250-500 kilogram putting kind of leech last week every mu in a suitable place to breed.
The cultural method of leech of the present invention, further, in step (2): the selection of described kind leech with to throw in: described kind leech specification be preferably 130-140 bar/kilogram; Every mu of water surface breeding density is preferably 20 kilograms.
The cultural method of leech of the present invention, further, in step (3): in described aquaculture management, the animal blood of throwing something and feeding weekly is congeal into block pig blood, ox blood or sheep blood, drops into appropriate one piece, removed after leech sucks every 4-6 rice.
The cultural method of leech of the present invention, further, in step (3): in the feeding process before entering winter, keeps temperature of cultivation between 15-25 DEG C by changing water.
The cultural method of leech of the present invention, further, in step (3): spiral shell feeding volume throws something and feeds 25 kilograms with every mu of water surface.
Compared with prior art, the inventive method is reasonable in design, workable, and the cultivation survival rate of leech is high.The cultivation of the leech of the inventive method is artificial cage culture, and the method is adopted and caught conveniently, and breeding process can grasp cultivation situation flexibly, and improves cultured output by effective cultural method, and culture benefit is remarkable.
