Summary of the history of the UK tuna drift net fishery. Opportunities for working with drift nets to catch albacore were first realised in June 1991 when the skippers and crews of three UK vessels took part in the fishery for the first time (Swarbrick, 1992). The three vessels involved were the Britannia V FH121, based in Mevagissey, the Sowenna PZ14and the -Bageergan PZ287Ar both based in

The tuna oceanic highways have turned into gauntlets lined with giant nets and endless lines of fishing boats. Fishermen have resorted to high-tech ways to catch tuna, including devices that draw the fish into bunches so that fishermen can catch more of them at once.
They included Japanese longline and baitboat fishing in thePacific, and United States baitboat fishing off California along the Mexican coasts.The traditional fisheries described above continued at the same time. After the SecondWorld War, the fishing areas for the Japanese tuna fishery were limited to its coast untilthe late 1940s or early 1950s. However, thereafter, the fisheries

The Puretic power block line was introduced in the 1950s and was the key factor in the mechanization of purse seining. The combination of these blocks with advances in fluid hydraulics and the new large synthetic nets changed the character of purse seine fishing. The original Puretic power block was driven by an endless rope from the warping head of a winch. Nowadays, power blocks are usually
A controversial plan to permit long-line fishing in the Maldives has shocked environmentalists and concerned citizens. While the government tries to justify the plan saying it will increase the fish catch and provide a higher income for the fishermen, the plan would have grave implications on the environment and the tuna fishery in the Maldives.

Best Practices in Tuna Longline Fisheries Introduction Tuna caught using longline fishing techniques is an important component of world tuna production but potentially imposes a heavy ecological burden on accidentally caught non-target species, also known as bycatch. However, although longline fishing poses real risks, it is possible to substantially reduce bycatch through adopting a range of

Abstract. We identify changes in pelagic longline fishing gear and practices that need to be accounted for in stock assessments. Pelagic longline fishers have continuously modified their fishing gear and practices to improve fishing power and catchability, which has altered the relationship between catch rates and abundance.

Tuna fishing fleets in the Pacific pose danger to wildlife
Longlining is a commercial fishing method commonly targeting swordfish, tuna and halibut, where hundreds or thousands of baited hooks hang at intervals along a single fishing line. The hooks (commonly called “J hooks”) cause problems for marine turtles when swallowed, usually resulting in death. Sharks, non-target billfishes and juvenile tunas are often hooked as well.
