Description
Technical field
The utility model relates to a kind of aquatic animal and fishes for device, and the controlled specification of dividing in a kind of specifically Procambius clarkii pond is fished for the ground cage assembly.
Background technology
The ground cage belongs to Locating Type cage kettle class fishing gear.This fishing gear history is not long, but development is very fast, and shape, size are varied, mainly are laid in the water bottom in pond, marsh, reservoir, rivers, lake, and extensive use and sparetime or specialty are caught swamp eel, loach, shrimp, crab, small fish etc.Material is a plastic optical fibre, and roughly being divided into has knot and do not have two kinds of knots.All there is use all parts of the country from south to north, scope very extensively.There are a lot of inlets cage both sides, ground, but the internal structure more complicated, treat that entering such as fishes and shrimps is difficult for out and is hunted down.Because this tool shape is long tubular, sink to water bottom, claim again " earthworm ".
It is that cage cage tip position increases by one section graded region on ground that the ground cage is fished in the Procambius clarkii classification, catches the relation of specification according to mesh size and Procambius clarkii, confirms the size of graded region mesh to reach the purpose that Procambius clarkii is fished in classification according to demand.Do not see the device that Procambius clarkii is fished in relevant classification at present both at home and abroad as yet.
Summary of the invention
The utility model technical issues that need to address provide the ground cage assembly that a kind of suitable Procambius clarkii classification is fished for.Growth rate significant difference in the Procambius clarkii breeding process; Same pond, Procambius clarkii specification when season is caught in arrival of putting in a suitable place to breed simultaneously are widely different; Removing the stage that needs seed can sell the shrimp that catches as the seed letter sorting; All the other most of production times only need reach the commercial sized prawn of specification, put back to the pond continued growth after the shrimp letter sorting, wait to raise and fish for listing again after reaching the commercial sized prawn specification.Especially seed breeding pond, after close shrimp bred juvenile prawn, the parent shrimp will all catch out, helped juvenile prawn and cultivated.But because prawn and shrimp be simultaneously at trapping region, juvenile prawn when catching and sorting is because individual little, and shell wall approaches, and is injured easily, sort go back to the pool after lethality very high, and sort process needs great amount of manpower, labour intensity is big.The present invention can effectively address the above problem, and only catches the Procambius clarkii commercial sized prawn that reaches the listing specification as required, and juvenile prawn can freely escape at graded region; Reduce catch, in the sort process to the injury of shrimp, improve back pool shrimp survival rate, raise labour efficiency; Remedied the blindness that cage is traditionally fished for; Thereby realized that the precision classification fishes for, simultaneously can improve the cage utilization rate, the purpose that saves production cost.
Technical scheme of the present invention is by one 1 font cage body, graded region and catch Na Qu and form; It is characterized in that the cage body is supported by the rectangle frame equidistance, the both sides outer wall submit misloading have the cage wall unidirectional fall must, be equipped with on the rectangle frame in the cage in the cage unidirectional fall must, cage body one side connects graded region and catches Na Qu.Graded region is that a cylindrical reinforcing bar supports, on cover large-mesh cage clothing, one section movable etting one end of fine mesh is fixed on cylindrical reinforcing bar and leans on to catch and receive district's one side, an end closes up with elastic cord, can and catch Na Qu at graded region and stir up and down.
The method of operating that the ground cage is fished in this classification is to fish for listing simultaneously like need commercial sized prawn and juvenile prawn; Can the movable etting of graded region fine mesh be left behind and cover graded region; In the time of at dusk the ground cage put into and fish for the pond, the next morning, results can be fished for results simultaneously with commercial sized prawn in the pond and juvenile prawn.As only fishing for commercial sized prawn; Can movable etting be pulled on, the ground cage is put into and is fished for the pond, and the Procambius clarkii that catches creeps along in-line cage body toward graded region; Through graded region the time; Owing to have only large-mesh cage clothing to cover, juvenile prawn can free escape out through large-mesh, and retaining what catch Na Qu all is the Procambius clarkii that reaches commercial specification.
The present invention innovates cage traditionally; Through the cage cage tip one end is provided with graded region and catches Na Qu on ground, can catch commercial sized prawn separately according to user's request, reduced that the Procambius clarkii juvenile prawn is hurt when catching; Avoid sorting the back juvenile prawn and return the higher shortcoming of pool lethality; Reduce manual sorting's labor cost, increase work efficiency, practiced thrift production cost.The movable etting of design can put down when needed and cover graded region simultaneously, and big or small Procambius clarkii is fished for simultaneously.A ground of the present invention cage, multiple use is practiced thrift cost, raises the efficiency, and guarantees survival rate, is particularly suitable for fishing for of Procambius clarkii cultivating pool.
Description of drawings
Fig. 1 representes that the Procambius clarkii classification fishes for ground basket structure sketch map
Technical scheme of the present invention is made up of three big zones, and an end is an in-line cage body, and an end is for catching Na Qu, and the centre is by the graded region connection, and movable etting is moved on the freedom as required and caught Na Qu, or covers graded region downwards.
Accompanying drawing 1 expression be that ground basket structure sketch map is fished in a kind of Procambius clarkii classification, long 500 centimetres of whole device, 1 processes framework by 4 millimeters reinforcing bar, wide 30 centimetres, high 20 centimetres, 30 centimetres at interval of frameworks.2 be unidirectional fall must, ellipse is formed by two, when Procambius clarkii climbed into, because action of gravity, network interface opened, and climbed into the back network interface and closed automatically.3 is unidirectional palpus in the cage, impels Procambius clarkii in the process of creeping, progressively to assemble at the position slightly to cage, and 4 is the fine mesh etting, 0.5 centimetre of mesh, and 5 is large-mesh cage clothing, 1.5 centimetres of meshes.6 is cylindrical reinforcing bar framework, 12 centimetres of radiuses, and 7 is the movable etting of fine mesh, 0.5 centimetre of mesh, 8 is the degree of tightness mouth, and 9 for catching Na Qu, and 10 is graded region.
Embodiment
1. method of operating is as only fishing for the Procambius clarkii commercial sized prawn that reaches specification, classification fished for the movable etting of ground cage graded region and pull on, being enclosed within and catching Na Qu; The ground cage gets rid of in the entry after cleaning out, and an end slightly surfaces, and is fixing with bamboo pole etc.; The whole cage that is classified to elongates and to put into water; General the ground cage is put at dusk the time, pour out the catches in the ground cage morning, and catching the Procambius clarkii that receives in the district this moment all is big specification; Juvenile prawn escapes from the large-mesh of graded region, but like the more 2-3 of catches hour results once.When the Procambius clarkii of size specification need be fished for simultaneously, movable etting put down covering graded region, stop that shrimp escapes to get final product.
