Description

Freshwater crayfish, fresh water crab culture pond removal of impurities boxes and baskets

Technical field

The utility model belongs to fishery utensil manufacturing field, and in particular to freshwater crayfish, culture of Chinese mitten crab pool removal of impurities boxes and baskets.

Background technique

During known freshwater crayfish, culture of Chinese mitten crab, since water resource is abundant, can also live away from home other biological, such as Various fish, millet shrimp, these wild fish can prey on freshwater crayfish, juvenile river crab；Food is striven in water body and shrimp, crab, is dropped Low efficiency of feed utilization；Oxygen is striven in water body and shrimp, crab, reduces yield per unit area；Therefore the massive losses of raiser are caused.At present On the market by the way of drug and tea seed cake removal of impurities, but drug and tea seed cake also result in freshwater crayfish simultaneously, river crab sloughs off Shell is difficult, and pollutes cultivation water source, there is no good technical solution to solve at present this defect.

Summary of the invention

The freshwater crayfish, culture of Chinese mitten crab pool removal of impurities boxes and baskets of the utility model, which pass through, manufactures distinctive wire mesh cage structures, reaches Trash fish can only be captured, the purpose of freshwater crayfish shrimp, river crab cannot be captured, thus preferably solves above-mentioned problem.

In order to achieve the above object, the utility model, which is achieved in that, sets the first rectangle skeleton, the second length Quadrate framework connects the first rectangle skeleton, each four angles of the second rectangle skeleton with four three-way columns, forms one long cube Shape frame respectively connects a fixed ring on four angles above the long cube-shaped frame, installs and weaves in long six face of cube-shaped frame Net forms long cube boxes and baskets, respectively sets three and four non-return bags in long cube boxes and baskets main-vision surface and backsight face, main-vision surface and The corresponding non-return bag in backsight face is connected with tie line, sets collection fish bag in left view face lower part, sets interior non-return bag in collection fish bag front end, It suspends a fragrant bait bag in midair in long cube boxes and baskets, sets big mouth in long cube boxes and baskets main-vision surface and backsight face lower part and adjust curtain, Slot regulating rod is set in non-return bag internal orifice；A long cube boxes and baskets are lain against into freshwater crayfish, in the culture of Chinese mitten crab pool, with rope system weight Object is fastened in fixed ring, and after boxes and baskets are fixed in water, the fragrant bait bag that boxes and baskets center is placed can lure trash fish to come in, trash fish, rice shrimp After coming in, due to special non-return bag, trash fish again goes out not going；Boxes and baskets are placed around the water inlet of pond, due to flowing water Stimulation also has good fishing result even if luring without using fragrant bait；It can be according to fishes and shrimps kind and specific environment to only It returns the big mouth of bag and slot is adjusted.

The beneficial effects of the utility model are: capturing the trash fish in culture pond by manufacturing distinctive wire mesh cage structures, improve Freshwater crayfish, river crab yield, retrieve the loss of raiser.

The utility model freshwater crayfish, river crab pool removal of impurities boxes and baskets are made in the following with reference to the drawings and specific embodiments further Detailed description.
