Abstract
The invention provides a pond snail spawning method. The pond snail spawning method includes the following technical steps: 1, when the water temperature is above 12 DEG C after early spring, selecting pubescent pond snails 1.5cm in length as breeding snails; 2, building a spawning pond which is 5-15m in length, 1.5-3m in width and 1m in depth, keeping the depth of pond water at 0.8m, keeping inlet and outlet water of the spawning pond in a micro flow state, putting the breeding pond snails into the spawning pond according to the density, namely 300-500 per square meter, for water stocking of the breeding pond snails, and feeding the breeding pond snails every 1-2 days; 3, arranging a spawning mesh in the spawning pond, enabling the upper end of the mesh to be exposed out of the water by 0.1m, enabling the lower end of the mesh to be soaked in the water by 0.2m, replacing the spawning net every 3-5 days, moving the mesh full of pond snail egg clusters to a hatching cultivation pond for hatching, putting a net without egg clusters into the spawning pond, and keeping the hatching water temperature of the hatching cultivation pond at 12-28 DEG C. The pond snail spawning method has the advantages that a large quantity of pond snails can be bred and cultivated by the method, and high-quality baits are provided for leech cultivation, so that growth speed and survival rate of cultured leeches are increased, and economic benefit of leech cultivation is improved.
Description
Technical field
The present invention relates to a kind of lamnaeid to lay eggs method, belong to special economic animal cultivation field.
Background technology
Lamnaeid is Mollusca Gastropoda Pulmonata animal.Lamnaeid is the important bait of much carnivorous and ominivore-fish, and because lamnaeid can not crush leech without operculum, therefore lamnaeid is the best bait of leech particularly leech seedling.But the bait mainly spiral shell of at present hirudiniculture industry cultivation leech, and cultivate leech and usually fall ill because being crushed by the operculum of spiral shell thus affect and grow death of even falling ill, particularly leech seedling is more easily crushed by the operculum of spiral shell and falls ill.Simultaneously because lamnaeid individuality is less, technical staff payes attention to not to it, also few to the research of lamnaeid.
Summary of the invention
The invention provides a kind of lamnaeid to lay eggs method, lamnaeid can be cultivated by amount reproduction, for hirudiniculture industry provides a large amount of high-quality bait, avoiding cultivation leech to fall ill because being crushed by spiral shell even dead, improving hirudiniculture survival rate and economic benefit.For avoiding above-mentioned drawback, the invention provides a kind of lamnaeid and to lay eggs method.
Concrete technical step is as follows:
(1), when water temperature is more than 12 DEG C after the annual beginning of spring, the sexually matured lamnaeid of body length more than 1.5 centimetres is selected as kind of a spiral shell.
(2) long 5-15 rice is built up, wide 1.5-3 rice, the spawning pond of dark 1 meter, keep pond water 0.8 meter, keep spawning pond Inlet and outlet water to be in miniflow state, put the density of lamnaeid kind spiral shell 300-500 with every square metre of water surface in a suitable place to breed, lamnaeid kind spiral shell is put into spawning pond, threw something and fed every 1-2 days a feed, feed is through and ferments and the duckweed powder pulverized.
(3) in spawning pond, arrange mesh sheet of laying eggs, mesh sheet is standard 20 object polyethylene mesh sheet.Mesh sheet upper end surfaces 0.1 meter, mesh sheet lower end is immersed in the water 0.2 meter, mesh sheet of once laying eggs is changed every 3-5 days, the mesh sheet sticking lamnaeid pieces of an egg is moved into hatching, cultivating pond hatch, change to the mesh sheet not with pieces of an egg at spawning pond, the hatching water temperature keeping hatching, cultivating pond is 12 DEG C-28 DEG C simultaneously.
Beneficial effect: adopt method of the present invention can a large amount of lamnaeid of Propogation and culture, for hirudiniculture provides the bait of high-quality, thus improves growth rate and the survival rate of cultivation leech, improves the economic benefit of hirudiniculture.
Embodiment
According to following embodiment, the present invention may be better understood, but example is only for illustration of the present invention, and also should can not limit the present invention described in detail in claims.
Example 1 lamnaeid is laid eggs method.
Build long 10 meters, wide 2 meters, the lamnaeid spawning pond of dark 1 meter, keeps pond water 0.8 meter, keeps spawning pond Inlet and outlet water to be in miniflow state.When water temperature is more than 12 DEG C after the beginning of spring, select the sexually matured lamnaeid of body length more than 1.5 centimetres as kind of a spiral shell.Put the density of 400, lamnaeid kind spiral shell with every square metre of water surface in a suitable place to breed, lamnaeid kind spiral shell is put into spawning pond, a feed of throwing something and feeding every 2 days, feed is through and ferments and the duckweed powder pulverized.
In spawning pond, arrange mesh sheet of laying eggs, mesh sheet is standard 20 object polyethylene mesh sheet.Mesh sheet upper end surfaces 0.1 meter, mesh sheet lower end is immersed in the water 0.2 meter, mesh sheet of once laying eggs is changed every 3-5 days, the mesh sheet sticking lamnaeid pieces of an egg is moved into hatching, cultivating pond hatch, change to the mesh sheet not with pieces of an egg at spawning pond, the hatching water temperature keeping hatching, cultivating pond is 12 DEG C-28 DEG C simultaneously.
