Our fleet at Global Atlantic Fishery consists of a carefully selected mix of purse seiners and longliners, each optimized for sustainable tuna fishing. Purse seiners are designed to encircle and capture schools of tuna with minimal bycatch, making them an environmentally responsible choice. Longliners, equipped with multiple hooks, allow for targeted fishing, further reducing the impact on other marine species.
A purse seiner is a type of fishing vessel designed to catch large quantities of schooling fish, such as tuna, in an efficient and sustainable manner. The vessel operates by deploying a large net, called a purse seine, around a school of fish. Once the fish are encircled, the bottom of the net is drawn tight, similar to pulling the drawstring on a purse, trapping the fish inside.
Purse seiners are particularly valued for their ability to selectively target large schools of fish, which minimizes bycatch and reduces the impact on non-target species. This method is considered one of the most sustainable forms of commercial fishing, as it allows for careful monitoring and management of fish stocks, ensuring that only mature fish are caught while younger populations are preserved.
A longliner is a specialized fishing vessel used for catching high-value fish species such as tuna, using a method known as longline fishing. This technique involves deploying a long main line, called the “longline,” which can be several kilometers in length, with thousands of baited hooks attached at intervals. The line is set in the water and left to drift or anchored, depending on the target species and fishing conditions.
Longliners are highly efficient for targeting specific types of fish, allowing for greater selectivity and reducing bycatch of non-target species. This method is especially effective for deep-sea fishing, where species such as tuna and swordfish are commonly found. The ability to carefully select fishing areas and depths helps ensure that juvenile fish and other marine life are largely avoided, supporting sustainable fishing practices.
