Abstract
The utility model relates to a Coregonusautumnalis running-water natural egg laying pond system, which belongs to the field of the aquaculture, and consists of a fish pond and an egg receiving net cage, a reverse-C-shaped end is arranged on one end part inside the cuboid fish pond, and a water pipe is arranged above the end; a C-shaped end is arranged inside the fish pond to be close to the other end part, the opening of the two ends is opposite to each other, a vertical primary retention barrier and a vertical secondary retention barrier are installed on the sharp part of the C-shaped end at intervals, the bottom of the fish pond between the two ends is inclined downwards from the reverse-C shaped end to the C-shaped end, the C-shaped end is provided with a water outlet, the bottom of the fish pond between the water outlet and a short edge wall of the fish pond is of a horizontal plane, the egg receiving net cage which consists of a cube net rack, and a front filter net, a rear filter net, a left filter net, a right filter net and a lower filter net, which surrounds the cube net rack, the egg receiving net cage is communicated with the water outlet through an egg conveying pipe, the short edge wall of the fish pond corresponding to the water outlet is provided with a drain port, and a flashboard is arranged on the drain port. The pond is close to the truth to simulate the natural environment and the water conditions of the original place of the Coregonusautumnalis, so the hatchability of the germ cell is improved by 15 to 18 percent compared with the rate of germination of the germ cell which is obtained by the manual egg taking.
Description
Technical field: recessed order whitefish flowing water natural spawning cell system of the present utility model belongs to aquaculture field.
Background technology: the original producton location of recessed order whitefish is the Baikal in the former Soviet Union, and it will be along the main stem Selenge Gol upstream, river of tracing back, to finish the last growth of its sexual gland in the antenatal bosom ovum phase.What recessed in the past order whitefish was adopted is the artificial breeding mode of pelyad, causes when the eyed eggs rupture of membranes rupture of membranes rate very low.
Summary of the invention: the purpose of this utility model is to propose a kind of near the recessed order whitefish flowing water natural spawning cell system of simulating original producton location natural environment and water condition truly.
The purpose of this utility model is achieved in that recessed order whitefish flowing water natural spawning cell system by the fishpond with connect ovum net cage two parts and forms, and the fishpond is a cuboid, end setting in the pond) the shape termination, above the termination, be equiped with the heavy caliber water pipe; Be provided with near the other end place in the pond that (shape termination, two termination openings are in opposite directions and right.In (tip, shape termination place installs vertical head, two roads at interval and blocks grid, at the bottom of the pond between two ends, from) shape termination to (the shape termination has a down dip.In that (shape sets out the mouth of a river on the termination, is horizontal plane at delivery port at the bottom of the pond between the minor face wall of fishpond, on it upright by by the square rack and be trapped among its front, rear, left and right, under five screen packs form connect the ovum net cage, wherein the below screen pack does not land, the rack upper surface is uncovered, and the screen pack mesh is less than fish-egg ovum footpath.Connect between ovum net cage and delivery port and be communicated with by oviduct.On the fishpond minor face wall of delivery port, having discharge outlet, be equiped with flashboard.
This spawning pond system makes obtained recessed order whitefish hatchability of fertile eggs improve 15-18% than the fertilized egg emergence rate of ovum artificial collection gained near the natural environment and the water condition of having simulated the original producton location truly.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is recessed order whitefish flowing water natural spawning cell system plan structure schematic diagram.
Legend: 1, discharge outlet, 2, connect the ovum net cage, 3, oviduct, 4, two roads block grid, and 5, slubbing blocks grid, 6, (shape termination, 7, the fishpond, 8, at the bottom of the pond, 9) shape termination, 10, water valve, 11, water pipe.
Embodiment:
Embodiment: as shown in Figure 1, recessed order whitefish flowing water natural spawning cell system is by fishpond 7 and connect ovum net cage 2 two parts and forms, and fishpond 7 is a cuboid, end setting in the pond) shape termination 9, above the termination, be equiped with heavy caliber water pipe 11; Be provided with near the other end place in the pond that (shape termination 6, two termination openings in opposite directions and right.In (6 tips, shape termination places installs vertical head, two roads at interval and blocks grid 5,4, at the bottom of the pond between two ends 8, from) shape termination 9 to (shape termination 6 has a down dip.(setting out the mouth of a river on the shape termination 6,8 is horizontal plane at delivery port at the bottom of the pond between the 7 minor face walls of fishpond, on it upright by by the square rack and be trapped among its front, rear, left and right, under five screen packs form connect ovum net cage 2, wherein the below screen pack does not land, the rack upper surface is uncovered, and the screen pack mesh is less than fish-egg ovum footpath.Connect between ovum net cage 2 and delivery port and be communicated with by oviduct 3.On the fishpond minor face wall of delivery port, having discharge outlet 1, be equiped with flashboard on it.
When laying eggs, open water valve 10 and emit the low Wenshan spring water fishpond 7 of going into by water pipe 11, make it produce stronger downward impact current, the recessed order whitefish parent of bosom ovum phase is put into ponds before the slubbing block 5, be close to make under original producton location natural environment and the water condition its trace back stream the upstream, finish the last growth of its sexual gland.Twice of every day collects fertilized egg and gets final product to connecing in the ovum net cage 2.It mainly is that the big fish of interception does not make it to leap in the pond that meets ovum net cage 2 places that head, two roads block grid 5,4, and the water level in the fishpond 7 is controlled by flashboard.
Claims (2)
