Abstract: | We present an analysis of quota regulation and discarding in multispecies fisheries, explicitly taking into account the costs of non-compliance with quotas and a possible discard ban, as well as the costs of selective fishing (avoidance effort). We examine the impact of a discard ban on vessels’ profit maximising behaviour, in particular where species quotas are not set in proportion to their availability on the fishing grounds, considering both non-tradeable quotas and ITQs. We show the interdependence between penalty rates for both discards and over-quota landings in determining quota market outcomes. We find that quota prices are sensitive to penalty rates and to the presence of restrictive quotas for “choke” species. |
