Seals and fish stocks in the North-East Atlantic

01-10-2010

Industrial and offshore fisheries using active gear have minor or insignificant interactions with seals, whereas some coastal fisheries based on passive gear can experience severe losses in catches and damages to gear. Seals also have impacts on fish farms, which can be protected by a combination of mitigation measures such as hunting, predator nets and acoustic deterrents. Seals spread a parasitic worm, which is seldom a problem in oceanic systems, but may be locally abundant close to main seal colonies.
