Again in Chinese patent literature CN102657139A, disclose a kind of leech and fed device, the technical scheme that adopts is, leech is fed device, the container and the hook that comprise upper opening, described hook is fixed in container top, the disclosed water frog problem of food pollution water quality of having fed device solves in this technical scheme, feed is put into container as the egg that shells, after feeding leech in the device immersion water, water enters in the container, and the egg that therefore shells can not spread and come, and still be positioned at container bottom, avoid polluted water.

But it is inconvenient still to exist leech to get food in feeding device, and cultivation density is little, the defective that stocking rate is little.Therefore, be necessary to work out a kind of new, get the hirudiniculture device that food is convenient, cultivation density is big, stocking rate is big.

Summary of the invention

The technical problem to be solved in the present invention is, provide a kind of new, get the hirudiniculture device that food is convenient, cultivation density is big, stocking rate is big.

For solving the problems of the technologies described above, the technical solution used in the present invention is, this hirudiniculture device, comprise the bottom and extend upward the leg that forms upper end open along the edge of bottom, the inwall of described leg has several steps, and described step is the stepped upper end that extends to leg always from the edge of bottom.

Adopt the hirudiniculture device of technique scheme, leech is got and eats conveniently, cultivation density is big, stocking rate is big; Such structure is adopted in bottom and extend upward the leg that forms upper end open along the edge of bottom, and it is convenient to throw in feed, and the while also is convenient to observe the hirudiniculture situation; The inwall of leg has several steps, described step is the stepped upper end that extends to leg always from the edge of bottom, put into practice discovery through the inventor, the posterior sucker of leech promotes leech digestion in the adsorbate guild of swashing, thereby accelerated growth rate, because the inwall of leg has several steps, feed is shed as in the hirudiniculture device, feed namely drops on the step, when slowly reducing water level to the step place, leech namely can be on the step and suck, along with the gradual slow decline of water level, leech can be swum to next step and be sucked feed, and water level namely changes water when descending or carries out the water circulation.

As a further improvement on the present invention, the vertical range D1 between the adjacent step is equidistant; The horizontal plane width D 2 of each step is equidistant, adopts such structure, and the beneficial effect of its generation is to make the hirudiniculture device inner regular standardized, the convenient making and the breed personal management.

As a further improvement on the present invention, described width D 2 is 1 ~ 3 times of distance B 1, and division bottom space as much as possible makes leech have more step plane and sucks feed.

As a further improvement on the present invention, also be placed with porous brick on the horizontal plane of described step, when in cultivator, throwing in feed, feed can be fallen in the porous brick, like this, leech will enter and get food in the porous brick, and the place of perching is provided for leech, further increase hirudiniculture density, strengthened stocking rate; In addition, have the phenomenon of casting off a skin in the developmental process of leech, and cast off a skin as early as possible and be conducive to leech and enter the next stage of growth, because the existence of porous brick is arranged, when leech creeped in porous brick, rough hole wall can help leech to cast off a skin in the porous brick, thereby has accelerated the process of casting off a skin of leech, be conducive to leech and grow up, improved the output of leech.
