Description
Technical field
The utility model belongs to hatch fish roe case, is specifically related to a kind of demersal egg fish oosperm hatching and fry rearing case.
Background technology
At present, also there is no a kind of facility that is specifically designed to the artificial incubation of demersal egg fish oosperm.Because the fertilized egg of demersal egg fish is mostly viscosity or microviscosity, when artificial incubation, must carry out unsticking to ovum, otherwise fish-egg can be together inter-adhesive, wherein the putrid and deteriorated meeting of unfertilized or dead fertilized egg affects rapidly the ovum of other normal developments, while is inter-adhesive because of fish-egg, ovum in the middle of being wrapped in can be dead because of anoxic, and therefore, the fertilized egg after unsticking could adopt conventional incubation facility to hatch; Meanwhile, when incubating oosperm after unsticking, must be placed in small-sized net cage, make it to be in the shallow seated groundwater that oxygen content is relatively high, and adopt aeration or manually manufacture current with to the continuous supplemental oxygen of water body, in order to avoid cause fertilized egg death because of anoxic.Fish-egg was combined with sperm in the rear about 30s time, the viscosity of fertilized egg progressively forms, so when unsticking, the detackifier that yellow mud Ba Shui, milk or talcum powder solution must be made in the 30s time of after fertilization joins in fertilized egg, stir gently, with in and the viscosity of fertilized egg, then pour in conventional incubation facility and hatch, after membrane, then fry is proceeded in fry rearing pond and cultivated.But, because the ovum viscosity that different demersal egg fish produce is not of uniform size, the more difficult assurance of unsticking time, time is shorter, unsticking poor effect, overlong time, particle in detackifier can stop up the pore on fertilized egg surface, affects the normal physiological functions such as the breathing of fertilized egg, makes incubation rate low; Demersal egg is often sunken in stone gap under field conditions (factors), in lotic water, hatches, and its natural habitat of the more difficult simulation of small-sized net cage shallow seated groundwater hatching, incubation rate is also therefore influenced; Conventional incubation facility is cement pit mostly, after building up, just can not move, and after fry membrane, must be transferred to fry rearing pond, complex operation.
Utility model content
The purpose of this utility model is the problem existing for prior art, provides a kind of incubation rate high, the hatching of demersal egg fish oosperm and fry rearing case easy to use.
The technical solution of the utility model is achieved in that
The hatching of demersal egg fish oosperm and fry rearing case, comprise a tank box, the one side on described casing top is provided with the first water inlet pipe, other limit is provided with the second water inlet pipe, in casing, be provided with a downward-sloping hatching plate of establishing some grooves by described the first water inlet pipe, in water tank, be provided with and overflow water pipe.
Described the first water inlet pipe is provided with slot-shaped delivery port, and described the second water inlet pipe is provided with poroid delivery port.
Described hatching plate is connected with casing by lifting rope.
Described casing is provided with effluent trough, described in overflow water pipe and be located in effluent trough, between casing and effluent trough, be provided with gauze.
Described effluent trough is provided with slot, and described gauze is movably arranged in slot.
Described effluent trough bottom sets out water hole, described in overflow water pipe and be provided with some apopores that are arranged above and below, described in overflow the apopore grafting of water pipe and effluent trough.
The both sides of described hatching plate upper groove are provided with dash limit, and the cell wall of groove recedes.
Described casing is provided with handle.
The beneficial effects of the utility model are: need not carry out unsticking to demersal egg affects hatching to avoid fertilized egg surface pores to be stopped up, can simulate the torrent ecological natural hatching habitat of demersal egg, improve hatching efficiency, integrate incubating oosperm and fry rearing simultaneously, fry survival rate is high, simple to operate, use conveniently moving.
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile of hatching plate in the utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the hatching of demersal egg fish oosperm and fry rearing case, comprise a rectangular tank casing 1, the one side on described casing 1 top is provided with the first water inlet pipe 5, the first water inlet pipe 5 is provided with slot-shaped delivery port 501, other limit is provided with the second water inlet pipe 3 of poroid delivery port 301, the first water inlet pipe 5, with on the second water inlet pipe 3, be respectively equipped with valve 6, 2, in casing 1, be provided with a downward-sloping hatching plate 4 of establishing some grooves 401 by described the first water inlet pipe 5, the both sides of hatching plate 4 upper grooves 401 are provided with dash limit 403, the cell wall 404 of groove 401 recedes, the surrounding of hatching plate 4 is connected with casing 1 by lifting rope 402, casing 1 sidepiece is provided with effluent trough 9, effluent trough 9 bottoms set out water hole, on apopore, be plugged with and overflow water pipe 8, overflow the body that water pipe 8 can adopt differing heights, also can on body, be provided with some apopores that are arranged above and below 801, casing 1 and effluent trough 9 between be provided with gauze 7, gauze 7 is movably arranged in the slot of effluent trough 9, the two ends of casing 1 are provided with handle 10.
When incubating oosperm, first one end of hatching plate 4 is fixed on to cabinet wall slightly lower than the first water inlet pipe 5 belows, and hatches the gradient of plate 4 by the length adjustment of other end lifting rope 402; Insert in the apopore of effluent trough 9 bottoms overflowing water pipe 8, gauze 7 inserts in the slot of effluent trough 9; Close the valve 2 of the second water inlet pipe 3, open the valve 6 of the first water inlet pipe 5, current flow to hatching plates 4 from the slot-shaped delivery port 501 of the first water inlet pipe 5, take advantage of a situation and torrent state under Imitating natural conditions from hatching plate 4.By insemination fish-egg along hatching plate 4 tops slowly pour into, with current slowly and under, stick at or be sunken in groove 401.Regulate the gradient of hatching plate 4, the size of control valve 6 simultaneously, regulates water velocity, and fertilized egg is in the groove 401 of hatching plate 4 all the time, is unlikely to be gone out by current.After the complete membrane of fertilized egg, withdraw hatching plate 4, valve-off 6, opens valve 2, and current are injected in casing 1 from the poroid delivery port 301 of the second water inlet pipe 3, give water body supplemental oxygen, ensure the needs of fry rearing.
Dash limit 403 on hatching plate 4 can form pipelined channel on groove 401, improves flowing water effect.The cell wall 404 of groove 401 recedes and can make better fish-egg stick in the groove 401 of hatching plate 4, is not easy to be gone out by current.Between effluent trough 9 and casing 1, separate with gauze 7, can prevent that the fry of demoulding from escaping from.Water level in casing 1 can be controlled by the water pipe 8 that overflows that differing heights body is set, or adopt that body is provided with apopore 801 overflow water pipe 8, also can control the water level in casing 1 by the aperture of valve.Need to move time, four people respectively lift leader 10, just can conveniently move.
