Abstract
A kind of small fishes roe hatching device, comprise hatchery, water inlet pipe, overflow pipe, hatchery inner chamber is rectangle, its bottom surface is the slope becoming angle with level, the least significant end place of bottom surface, hatchery evenly arranges water inlet shower nozzle, the side that hatchery is positioned at bottom surface lowest part has overflow groove, the overflow pipe highly do not waited is housed below overflow groove; The long limit of top cap screen window frame is identical with the long edge lengths of hatchery inner chamber, and the upper side frame of top cap screen window frame is concordant with top, hatchery, and the lower frame of top cap screen window frame is fixed on and is equipped with on the hatchery medial surface of overflow pipe.Small fishes roe hatching device of the present utility model; in hatchery, bottom design becomes ramp shaped; by the water flow of inlet tube and outlet tube; the water capacity in hatchery is easily rolled, protects the fresh of water quality, reduce the generation of fish saprolegniasis; its water saving that not only saves land; and saving manpower, the dead ovum grain of convenient removing and the egg membrane that comes off, can improve hatch fish roe rate more than 20%.
Description
Technical field
The utility model relates to artificial propagation of fish technical field, especially a kind of small fishes roe hatching device.
Background technology
At present, artificial propagation of fish hatching apparatus is generally circular hatching channal, incubation tank, hatching pail, incubation plate etc., and wherein, the large-scale artificial breeding that circular hatching channal is mainly applicable to floatability fish-egg is produced; Incubation tank, hatching pail are applicable to middle-size and small-size scale artificial propagation; Incubation plate is used for the breeding of tentative small-scale.For the small fishes such as loach, Odontobutis obscura, due to factors such as individuality are little, fish brood amount is few, ovum grain is little or lay eggs in batches, employing circular hatching channal water consumption is large, cost is high; Adopt the Lentic hatching such as incubation tank, hatching pail, incubation plate, during incubating oosperm, have unfertilized dead ovum grain and the egg membrane etc. that naturally comes off ruins water quality, have a strong impact on hatch fish roe, need manually to remove in time, workload greatly and incubation rate is lower.
Summary of the invention
The purpose of this utility model be just to provide a kind of floor space little, save labor, the small fishes roe hatching device of hatch fish roe rate can be improved.
Small fishes roe hatching device of the present utility model, comprise hatchery, water inlet pipe, overflow pipe, it is characterized in that, hatchery inner chamber is rectangle, its bottom surface is the slope becoming angle with level, and the least significant end place of bottom surface, hatchery evenly arranges water inlet shower nozzle, and water inlet shower nozzle is connected with water inlet pipe, the side that hatchery is positioned at bottom surface lowest part has overflow groove, the overflow pipe highly do not waited is housed below overflow groove; The long limit of top cap screen window frame is identical with the long edge lengths of hatchery inner chamber, the upper side frame of top cap screen window frame is concordant with top, hatchery, the lower frame of top cap screen window frame is fixed on and is equipped with on the hatchery medial surface of overflow pipe, and overflow pipe is in above top cap screen window frame; Pipe of emerging also is equipped with in hatchery, and the fry hatched is collected from pipe of emerging.
Small fishes roe hatching device of the present utility model, during use, open the water inlet pipe switch outside hatchery, water inlet shower nozzle in pond gets final product water outlet, can to control to intake in hatchery the water velocity of shower nozzle and water yield by regulating conduit switch, hatch initial flow rate of water flow general control at 0.2m/s, mid-term can increased water flow, reduces current after membrane.40 ~ 500,000, fertilized egg can be thrown in every hatchery, when finding between the incubation period that screen window is filtered in the blocking of fertilized egg demoulding, can brush away screen window screen cloth and can remove dirt by direct brush.
Small fishes roe hatching device of the present utility model; in hatchery, bottom design becomes ramp shaped; by the water flow of inlet tube and outlet tube; the water capacity in hatchery is easily rolled, protects the fresh of water quality, reduce the generation of fish saprolegniasis; its water saving that not only saves land; and saving manpower, the dead ovum grain of convenient removing and the egg membrane that comes off, can improve hatch fish roe rate more than 20%.
