Abstract
The utility model relates to a pond culture silvery pomfret embryonated egg collection device, including the circular frame and the toper string bag, string bag both ends opening, the heavy -calibre end is fixed in on the circular frame, circular frame on set up the float with many with fixed rope, many one end with fixed rope evenly are fixed in circular frame, other end coalescence together, coalescence department of fixed rope is fixed with forward stay cord and reverse stay cord. Put into the pond with collection device, alone handheld forward stay cord, alone handheld reverse stay cord makes a round trip to spur collection device, goes into embryonated egg collection at the small -bore end of the string bag. Many fixed rope one end evenly are fixed in circular frame, and other end coalescence fixed mode together makes the coalescence point of forward stay cord and reverse stay cord change at will at tensile in -process, is favorable to the nimble pulling direction that conveniently changes. The beneficial effects are that, simple structure, easily popularization, convenient operation is favorable to portably and collects pond culture silvery pomfret embryonated egg high -efficiently.
Description
Technical field
The utility model relates to pond culture silvery pomfret fertilized egg gathering unit.
Background technology
Pond culture is one of Main Patterns of China's Coastal Areas mudflat aquaculture, and the cultivation of development Coastal beach is the important means of China's marine fish culture industry development.Donghai Aquatic Products Inst., China Aquatic Science Research Academy just starts the research tackling key problem to silvery pomfret artificial breeding and cultural technique aspect from the beginning of this century, achieved a series of achievement in research up to now, comprise tentatively establish silvery pomfret artificial breeding technique flow process, captured its full artificial breeding and find out multiple be suitable for silvery pomfret propagate Modes and methods artificially.In recent years, East Sea aquatic products research institute scientific research personnel is improved by technical method, successfully utilizes pond culture pattern to cultivate and obtains the parent propagating silvery pomfret artificially, shows that the pond culture model comparision after project team's improvement is applicable to the cultivation popularization of silvery pomfret.But at mating period, pond culture silvery pomfret also has inconvenience part, as fertilized egg is often scattered in whole pond, cause silvery pomfret fertilized egg not easily collecting.Therefore, a kind of pond culture silvery pomfret fertilized egg gathering unit is needed.
Utility model content
The device that the purpose of this utility model is to provide a kind of simple and effective to collect pomfret fertilized egg collects.
For reaching above object, provide a kind of pond culture silvery pomfret fertilized egg gathering unit, comprise circular frame and the taper string bag, string bag both ends open, heavy caliber end is fixed on circular frame; Described circular frame arranged float and follow static line more, circular frame is evenly fixed in many one end with static line, and the other end coalesces together; The coalescent place of static line is fixed with forward stay cord and reverse stay cord.
Preferably, the described string bag is 80 object bolting silk nets.
Preferably, the small-caliber end of the described string bag is cylindricality.The tubular structure of small-caliber end is conducive to fish-egg and collects.
Preferably, described static line has three, and circular frame is evenly fixed in its one end, and the other end is together coalescent.Three static lines can reach better stability and flexibility.
Preferably, described static line is all isometric.
Preferably, described float has two, is fixed on circular frame both sides.
Pond culture silvery pomfret fertilized egg gathering unit of the present utility model, after taper string bag small-caliber end is tied a knot, gathering unit is put into pond, the hand-held forward stay cord of one people, the hand-held reverse stay cord of one people pulls gathering unit back and forth, because silvery pomfret fertilized egg is buoyant egg, by pulling back and forth, fertilized egg is collected into the small-caliber end of the string bag.Circular frame is evenly fixed in many static line one end, the coalescent fixed form together of the other end, make the coalescent point of forward stay cord and reverse stay cord and circular frame not at same plane, and can be comparatively free in drawing process, be conducive to changing flexibly and easily pulling direction.
The beneficial effects of the utility model are, structure is simple, be easy to promote, easy to operate, are conducive to easy and collect pond culture silvery pomfret fertilized egg efficiently.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model pond culture silvery pomfret fertilized egg gathering unit;
Wherein:
The 1-circular frame 2-float 3-string bag
The reverse stay cord of 4-static line 5-forward stay cord 6-
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1:
A kind of pond culture silvery pomfret fertilized egg gathering unit according to Fig. 1, comprises circular frame 1, float 2, the string bag 3, static line 4, forward stay cord 5 and reverse stay cord 6 that material is stainless steel coil.The string bag 3 is 80 object bolting silk nets, and overall is taper, and both ends open, form heavy caliber end and small-caliber end, its Large diameter end is fixed on circular frame 1, and small-caliber end tail end is cylindricality.Each one end fixing a float 2, three isometric static lines 4, circular frame 1 both sides is evenly fixed on circular frame 1, and the other end is together coalescent and tie a knot.Forward stay cord 5 and reverse stay cord 6 are all connected to the position that three static lines 4 are tied a knot.
Embodiment 2:
A kind of pond culture silvery pomfret fertilized egg gathering unit, circular frame 1 diameter is 1.2 meters.During use, determine the length of forward stay cord 5 and reverse stay cord 6 according to pond length, generally length is more than the twice of pond length.First the string bag 3 small-caliber end is tied a knot, pond culture silvery pomfret fertilized egg gathering unit is slowly put into pond, two people stand in the two ends in pond respectively, the hand-held forward stay cord 5 of one people, the hand-held reverse stay cord 6 of one people pull unit back and forth, because silvery pomfret fertilized egg is buoyant egg, by pull unit back and forth, fertilized egg is gathered in the cylindricality small-caliber end of the string bag 3 gradually.After collection terminates, first fertilized egg is concentrated on the cylindricality small-caliber end of the string bag 3, then small-caliber end opened and collect.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
