Bycatch
Bycatch
Bycatch (pronounced: /ˈbʌɪkætʃ/), also known as incidental catch, refers to the unintended fish and other marine species that are caught while catching certain target species and target sizes of fish, crabs etc.
Etymology
The term "bycatch" is compound of "by" and "catch", which literally means the catch which is by or aside the main target. The term has been used in fishing industry since the late 20th century.
Definition
Bycatch is a term in the fishing industry which refers to species that are caught unintentionally while targeting a specific species of fish. This can include non-target fish species, as well as marine mammals, seabirds, and sea turtles. Bycatch is often discarded back into the sea, either dead or dying.
Impact
Bycatch can have a significant impact on marine ecosystems, as it can lead to overfishing and the decline of fish populations. It can also cause harm to endangered species that get caught unintentionally.
Mitigation
Various strategies have been developed to reduce bycatch, including the use of more selective fishing gear and techniques, changes in fishing practices, and the implementation of bycatch reduction devices.
