Incidental catch

Incidental catch

Incidental catch is the catch of non-fish species, caught in the course of commercial fishing practices. Examples of non-fish species are seabirds, and marine mammals and reptiles, such as dolphins, seals and sea turtles.

For instance longline and trawl fisheries can cause the death of seabirds which are attracted to the fishing vessels. Mitigation measures can be put in place to reduce this problem and have been very successful in some cases, such as the Southern Ocean Patagonian toothfish fisheries.

Incidental catch can be contrasted with bycatch, which is a general term for the catch of all fish and non-fish species other than the targeted species.
