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. The operational definitions used by the FAO for incidental catch and other related catches are as follows:〔Alverson DL, MH Freeberg, SA Murawski and Pope JG (1994) (A global assessment of fisheries bycatch and discards ) FAO Fisheries, Technical paper 339, Rome. ISBN 92-5-103555-5.〕 * 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. ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Incidental catch」の詳細全文を読む スポンサード リンク
