The etting of 2) cutting correspondingly-sized covers frame facet and bottom surface, thereby makes netting gear;
3) in netting gear, fix some baits;
4) rope of getting a lightweight is as buoyant rope, and an end of buoyant rope is by connecting the mode bifurcated of some ropes, ties up to respectively the some places on the endless metal rod of netting gear top behind the bifurcated;
5) other end with buoyant rope ties up on the fixture, fixture is fixed on the ground on cultivating pool bank again;
6) fasten a float at buoyant rope;
7) one or more groups netting gear is put into cultivating pool, owing to action of gravitation, opening makes progress naturally, and sinks under water after the netting gear entry;
Whether 8) observe float rocks;
9) observe float and rock after, the pulling buoyant rope is to pack up netting gear;
10) take out as required suitable big or small Scylla paramamosain in the netting gear;
11) other aquaculture organisms in the netting gear are put back to cultivating pool;
12) in netting gear, change and again netting gear is put into cultivating pool behind the new bait and carried out next time seizure;
13) repeating step 7 is to step 12, until capture the Scylla paramamosain of sufficient amount.
Described metal bar is stainless steel bar, and diameter is 4.5mm.
Described etting adopts polythene material to make, and its screen frequency is 40 orders.
In the described step 3, bait adopts the mode of binding to be fixed in the netting gear.
Fix three baits in the described netting gear.
Described bait is low value animality bait.
Described low value animality bait is small fish or bivalve shellfish.
Described buoyant rope adopts polythene material to make.
Described fixture is the cement bar.
In the described step 7, netting gear is put into along the edge of cultivating pool.
Beneficial effect
The present invention adopts open netting gear to catch Scylla paramamosain, utilize bait to lure to draw Scylla paramamosain and enter in the netting gear, can from polycultured ponds especially Mixed cultivation of prawn and crab pond, effectively catch Scylla paramamosain, and other kinds of raising together with can be put back to, can select as required to catch the Scylla paramamosain of different size, can prevent that again the crab class from cutting one another's throat and causing damage, thereby improve cultivation efficient that apparatus structure is reasonable and succinct, cost is low, easy to operate, practical.
