Abstract

Due to the increasing environmental awareness of the public, marine environmental protection became a general interest. Since fishery is one of the strongest direct influences of man on the marine ecosystem, it became criticised, especially because of the discarding of unused fish, which is considered as a waste of the resource. In the different types of fisheries the calculation of the amounts of discards in relationship to the landings vary strongly. One of the reasons is, however, the different use of the terms 'bycatch' and 'discard'. Thus it is important to work with equal terms and definitions, so that fishermen, protectionists and ecologists talk the same language. This contribution tries to define the following terms achieving a generally acceptable terminology which is also explained by the attached diagram.
