Abstract
The utility model relates to a temporary rearing device for fish fry initial feeding. The temporary rearing device for fish fry initial feeding comprises a net cage, a fixing frame is arranged at an upper opening of the net cage, a fixed support is arranged at the bottom of the net cage, and fixing ropes are arranged at four corners of the net cage and respectively fixedly connected with vertical columns. The temporary rearing device for fish fry initial feeding is mounted in a pond, a water body space of the pond is fully utilized, possible water quality problem during fish fry initial feeding process in a cement pond can be lowered or avoided, and fish fry initial feeding process is benefited. By the temporary rearing device for fish fry initial feeding, not only construction of the cement rearing pond can be avoided, but also an operation program for fish fry initial feeding to be turned out of the pond can be finished quickly. The temporary rearing device for fish fry initial feeding is simple and convenient to mount, laborsaving, and fish fry initial feeding cost saving.
Description
Technical field
The utility model belongs to aquaculture field, is specifically related to a kind of fry opening and supports device temporarily.
Background technology
The cultivation of aquatic product sprout is the key technology of aquaculture.Present most of nursery and raiser still continue to use and traditional carry out the fry opening at cement pit, Tu Tang or native pool purse seine and cultivate.There is following shortcoming in these three kinds of modes: the cement pit floor space is big, builds the expense height, and after opening finishes, and the fry rapid inconvenience of moving about is fished for and changeed the pond, and will notice preventing that in the nurturing period cultivate water from worsening the influence that brings; Adopt Tu Tang to carry out the fry opening, survival rate of fish fry is lower, and harmful animal etc. are more, and secondly the Tu Tang space is bigger, and bait disperses, and fry ingests and has any problem; Adopt the mode of native pool purse seine to carry out the fry opening, require at the bottom of the pond smoothly, need install protecting wire net additional at the side of a pond during use in case harmful animal, during use in the purse seine water quality easily worsen, water temperature difference is big, is not easy to management.
The utility model content
Technical problem to be solved in the utility model provides a kind of fry opening simple in structure, that do not take up an area of and supports device temporarily.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: a kind of fry opening is supported device temporarily, it includes net cage, upper shed place at net cage is provided with fixed frame, the bottom of net cage is provided with fixed support, four jiaos of net cage are provided with stationary rope, and stationary rope is fixedlyed connected with column respectively.
Press such scheme, described support bracket fastened four jiaos are respectively equipped with weight, and weight does not contact with the bottom.
Press such scheme, described column has 4.
Press such scheme, be provided with the packaging bag press strip at the bottom outside edge of net cage.
Press such scheme, described net cage is that 80 order nylon mesh sheets are made; Described fixed frame and fixed support adopt flitch to be made.
Press such scheme, the size of described net cage is long 2m, wide 1m, high 0.6m; The size of described fixed frame is long 2m, wide 1m.
This fry opening is installed in the pond is supported device temporarily, take full advantage of the pond waters space, and can reduce even avoid the cement pit opening to cultivate the quality problem that may run into, be beneficial to fry rearing.This fry opening is supported device temporarily not only can remove building of cement cultivation pond from, can also finish the operation sequence that fry is produced down the pool fast.This fry opening is supported the device simple installation temporarily, saves manpower, saves the fry rearing cost; And can effectively prevent harmful animal.
The beneficial effects of the utility model are: 1, simple in structure, easy to use.2, not only floor space is little, and the influence that not worsened by cultivate water.3, survival rate of fish fry height.4, lowered working strength of workers.5, can reuse.6, expense is low.

Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of net cage.
Fig. 3 is support bracket fastened structural representation.
Fig. 4 is the structural representation of net cage bottom.
Among the figure: 1, net cage, 2, fixed frame, 3, stationary rope, 4, fixed support, 5, column, 6, weight, 7, the packaging bag press strip.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 4, a kind of fry opening is supported device temporarily, it comprises that the size of being made by 80 order nylon mesh sheets is the net cage 1 of 2m * 1m * 0.6m, upper shed place at net cage 1 is provided with the fixed frame 2 that is of a size of 2m * 1m by the flitch making, the bottom of net cage 1 is provided with the fixed support of being made by flitch 4, four jiaos of net cage 1 are provided with stationary rope 3, and stationary rope 3 is fixedlyed connected with 4 root posts 5 respectively.
In the present embodiment, can be at the support bracket fastened four jiaos weights 6 that heavy 5kg is set respectively, and weight 6 does not contact with the bottom.For the bottom margin that makes net cage 1 becomes the plane of no concave-convex, can be provided with packaging bag press strip 7 at the bottom outside edge of net cage 1.
Installation process:
(1) stationary rope 3 bindings of fixed support 4 with net cage 1 bottom is fixed, make net cage 1 bottom be the 3 D plane shape, do not stay the dead angle;
(2) in the pond bottom flat place with four root post 5(bamboo poles) net cage 1 fixed size is good by being slightly larger than, four stationary ropes 3 on the fixed frame 2 that net cage 1 is suitable for reading are fixed on column 5(bamboo pole) on, 2 of the weight 6(of a heavy 5kg such as common bricks are respectively settled at the angle around fixed support 4), weight 6 should be suspended in the water, does not sink to the bottom;
(3) pond water filling, the degree of depth is so that fixed frame 2 upper edges of net cage 1 upper shed are as the criterion apart from water surface 30cm, and about underwater net cage 1 degree of depth 50cm, general pond needs about water filling degree of depth 1m.
Use:
(1) at lower storage reservoir preceding 1 day, full pond used bio-fertilizer to foster and apply fertilizer;
(2) new system net cage 1 needs to install in 1-2 days in advance, in order to the attached collection of a spot of algae is arranged on the net sheet;
(3) fry is bought the back back and directly put into net cage after the balance transition water temperature in the pond, and breeding density is 200,000 tails/m2;
(4) treat directly to throw something and feed behind the fry opening fairy shrimp of artificial incubation was thrown something and fed 3-4 time, and fry can be put into the pond after throwing something and feeding 2-3 days and cultivate in general day;
(5) the fry method of releasing: earlier the weight 6 on the fixed support 4 is unloaded, again the stationary rope 3 of four jiaos of net cage 1 openings is untied, only need this moment two long corners of net cage 1 bottom are mentioned and make whole net cage 1 be inverted in the water surface, make the case mouth down, fry can be swum in the pond at leisure;
(6) net cage 1 after using is after simple the cleaning, puts that airing is dried under the daylight can reinstall use.
The utility model reduces the floor space that the fry opening is cultivated, remove the expense of building of cultivating the pond from, the influence that the water quality deterioration that reduction causes because of ight soil, residual bait brings, improve the operating efficiency that fry is produced lower storage reservoir effectively, reduce opening fry rearing cost, reach and save the area and water-saving effect.
The above; only being preferred embodiment of the present utility model, is not that the utility model is done any pro forma restriction, and those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification; equivalent variations or modification all drop in the protection domain of the present utility model.
