The square net has the advantages of good expansibility, strong selectivity to the size of the fishing object, saving material and low resistance, etc.Also ,square net is widely applied in sports area ,such as soccer net ,tennis net ,four square volleyball net etc .
The square net has the advantages of good expansibility, strong selectivity to the size of the fishing object, saving material .Due to the small stress in inland waters, square mesh is suitable for use.
1. Customized fishing gear, such as net cage, block net, etc. after these fishing gears adopt square mesh, in addition to saving materials, reducing cost and simplifying assembly, good filterability will reduce the retention of dirt, improve the flow capacity of water body, increase the firmness, and reduce the loss of stinging
2. Ground trawl net is the most widely used fishing gear in inland waters
The large-scale net in pond accounts for the majority of them. The experimental application shows that the total weight, resistance and cost of the net are significantly reduced or reduced after the large-scale net is replaced with square mesh. After the net is reduced, the sinking force can be increased, so as to improve the catching rate of bottom fish. Especially, the square mesh has good selectivity, which can be used to catch large fish and keep small fish, so as to achieve uniform fishing The purpose of breeding benefits.
3. The purse seine used in inland waters of Purse Seine is small in scale, small in water depth, less fish in single net, and less strict requirements on settling speed and working height. Therefore, square mesh can also be used. After changing to square mesh, the weight of fishing gear can be reduced and the cost is low, especially the labor intensity of manual netting can be reduced.
4. Trawler type fishing gear, fishing gear of fishing net, has fast moving speed and large force, and requires net type and rhomboid mesh, which is easy to meet technical requirements. Therefore, diamond mesh is still better for wing net and body net part of trawl, while square mesh can be used for bag net, because of its good expansibility and selectivity, it is easy for small fish to pass through.
Also ,square net is widely applied in sports net and fence net ,such as soccer net ,tennis net ,four square volleyball net,playground net,golf net etc .
