Abstract
The utility model discloses the shelling of combined type river crab and perch device, it is characterized in that, perch device and formed by column, pole, pvc pipe; Use the shelling of the utility model combined type river crab to perch device, the pole latch of the pole bottom of some insertion pvc pipes is inserted in the pole hosel of column, become a complete river crab shelling and perch device, the column of the bottom of column cone is inserted to culture of Chinese mitten crab water bottom fixing, when river crab finds shelling habitat, enter pvc pipe, a river crab inhabits in a pvc pipe, between river crab, do not interfere with each other, do not affect the shelling of river crab, and river crab is away from the anaerobic environment of bed mud, river crab shelling survival rate is high, robust growth, respond well.
Description
Technical field
The utility model relates to fish production field, and specifically device is perched in the shelling of combined type river crab.
Background technology
River crab is generally liked perching in hole, the environment that the river crab of cultivation does not dig a hole in water body, generally on the bed mud of water bottom, perch activity, especially in when shelling, river crab physique very a little less than, be very easily subject to the invasion and attack of other animals, and river crab shells on water bottom bed mud, the easy anoxic of bottom environment, often causes river crab survival rate to decline, and culture benefit is not high.
Summary of the invention
For overcoming above-mentioned defect, the utility model has designed the shelling of combined type river crab perches device.
The technical solution of the utility model is, device is perched in the shelling of combined type river crab, it is characterized in that, perching device is comprised of column, pole, pvc pipe, the wall side interval of described column arranges some pole hosels, each pole hosel is inserted a pole of perching pipe with river crab, and pointed column cone is arranged in the bottom of described column; One end of described pole arranges pole latch, and pole latch is convenient to insert pole hosel, makes pole and column angle at 45 °, and the other end of pole arranges retainer ring; Described river crab perches pipe for the pvc pipe of 10 centimetres of diameters, pvc pipe is cut into the short tube of 40 centimeter length, cross section is the inclined-plane with body angle at 45 °, mouth of pipe cross section, two ends is parallel, pvc pipe is inserted in the retainer ring of upper end of pole, one end is opening up, and the mouth of pipe is the level of state, and it is that 10 object polythene net sheets seal that the other end mouth of pipe is used mesh.
Beneficial effect: use the shelling of the utility model combined type river crab to perch device, the pole latch of the pole bottom of some insertion pvc pipes is inserted in the pole hosel of column, become a complete river crab shelling and perch device, the column of the bottom of column cone is inserted to culture of Chinese mitten crab water bottom fixing, when river crab finds shelling habitat, enter pvc pipe, a river crab inhabits in a pvc pipe, between river crab, do not interfere with each other, do not affect the shelling of river crab, and river crab is away from the anaerobic environment of bed mud, river crab shelling survival rate is high, robust growth, respond well.
