In order to realize above-mentioned purpose, the utility model adopts following technical measures:
A kind of fish biopsy sample harvester, it comprises float, cage body, bait mesh bag, iron annulus framework, trumpet-shaped inlet, net sheet, anchor, rope, its annexation is: the first anchor links to each other with the first float, cage body respectively, the second anchor links to each other with the second float, cage body respectively, inner each the iron annulus framework of cage body links to each other with the net sheet, and the bait mesh bag links to each other with a middle iron annulus.One end entrance of cage body is horn-like, and an end of larger opening is towards network interface.
Described trumpet-shaped inlet plays induces fish to enter cage, reduces fish and returns the chance of escaping.The supporting construction that horn-like device is comprised of hard material forms three-dimensional trumpet-shaped inlet passage.
Described cage body is surrounded by the metal iron hoop of circular support structure and the net sheet of nylon monofilament woollen yarn knitting.
Described cage body is cylinder in the middle of being, tail end is the barrel-like structure of the sharp end of cone, and the space that cage body net sheet surrounds mainly plays a part to be detained, the class of breeding fish temporarily.
Described net sheet is provided with the circulus for the fixed network sheet.
The inner bait bag of described cage body is the mesh pocket assembling structure that is formed by the nylon monofilament woollen yarn knitting, and sack can shrink.It is unsettled to insert cage body inside middle, is used for depositing fish food, plays attracting action.
Described fish food bag refers to the food lumps that soya-bean cake or other commercial fish feeds are made.
Described anchor is cube or the rectangular-shaped thing of being made by heavy metals such as lead or iron, with the polythene rope cage body two ends of ining succession, plays fixedly the cage body in ad-hoc location.
Described float is foam plastic float, and it can help to keep cage figure shape and fix its levitation position at the buoyancy that the water surface produces, and also can be used as the searching target on the river surface.
The rope of this device each several part of described connection is polythene rope, is used for connecting, stretching, fix the effect of this device.
Compare with prior art, the utility model has the advantage of:
1, scientific structure is simple, and the inner space of cage body is little to the fish sample injury of catching, and can keep fresh and alive;
2, can this device be fixed on different water layers by regulating rope, be applicable to collect the fish sample of different water layers;
3, cheap, easy to operate, operating cost is cheap, the operation mobility strong.
