Incidental catch

In fishing, incidental catch is that part of the catch which was not originally targeted, but was caught and retained anyway. It can be contrasted with discards, which is that part of the catch which was not originally targeted, but was caught and returned to the sea, and bycatch, which is for all the species caught apart from the targeted species.

Bycatch = Incidental catch + Discarded catch

The operational definitions used by the FAO for incidental catch and other related catches are as follows:[1]

  • Target catch: The catch of a species or species assemblage which is primarily sought in a fishery, such as shrimp, flounders, cods
  • Incidental catch: Retained catch of non-targeted species
  • Discarded catch (usually shortened to discards): That portion of the catch returned to the sea as a result of economic, legal, or personal considerations.
  • Bycatch: Discarded catch plus incidental catch.
