大围缯与高效率的拖、围网一样,在捕捞作业中也有一个正确使用和合理调整网具的技术性问题。並且由于它具有围、拖、张的作业特点,能捕上、中、下各水层的密集鱼群,这个技术问题更为突出。当渔船探测到鱼群后,能否迅速有效地把鱼捕上来,除了渔民需具备熟练的起放网操作技术外,在很大程度上还取决于能否正确地使用和调整网

As with high-efficiency towing and seining networks, Tai Wai Island also has a technical issue of proper use and reasonable adjustment of gear in fishing operations. And because of its features of enclosing, dragging and stretching, it is capable of catching dense fish groups in upper, middle and lower aquifers. This technical issue is even more outstanding. When fishing vessels detect fish stocks, the fish can be quickly and efficiently catched up, in addition to fishermen with skilled access control technology, but also to a large extent depends on the proper use and adjustment of the network
