Longline fishing, while effective, presents several challenges: By-catch: One of the most significant issues with longline fishing is the unintentional catch of non-target species, including endangered species such as certain sharks, turtles, and seabirds. Gear Loss: Currents, marine traffic, predators, or operational errors can lead to lost or abandoned longlines, contributing to marine pollution and posing threats to marine life. Environmental Impact: Bottom longlining can disturb sensitive seafloor habitats, potentially damaging ecosystems and degrading fish habitats. Regulations and Restrictions: To protect marine resources, many areas have regulations that restrict where, when, and how longlining can occur, requiring constant adaptation from fishers. Operational Costs: The cost of gear, bait, fuel, and maintaining equipment can be high, especially if the catch is not sufficient. Safety Concerns: Longlining operations, especially in rough weather or in waters with strong currents, can pose risks to the crew.
