purseseiners

Purseseining is a method of commercial fishing that utilizes a large net, known as a purse seine, to encircle schools of fish. The net is deployed around the fish and then closed at the bottom, much like a drawstring purse, to prevent their escape. This technique is highly effective for catching pelagic fish that swim in large schools, such as tuna, sardines, mackerel, and herring.

The operation typically involves a specialized vessel and a crew of experienced fishermen. A skiff may be used to help deploy the net, which can be several miles long and hundreds of feet deep. Once the net is set, it is gradually pulled in by the purse line at the bottom, gathering the fish within its confines. The catch is then brought aboard the fishing vessel.

While efficient, purseseining has been a subject of debate regarding its impact on marine ecosystems. Concerns have been raised about bycatch, which is the unintentional capture of non-target species. Efforts are ongoing to develop and implement fishing practices that minimize bycatch and promote sustainable fisheries management. Regulations and quotas are often in place to manage the size and scope of purseseine operations. The technique is employed globally in various marine environments.
