Alboran Sea which is subject to a fisheries management plan (2014–2019). Red
seabream fishery has been subject to many changes over time because of successive
recovery and management plans (Table 22.3). It is currently managed through effort
controls that mainly restrict the number of fishing trips per season and the technical
characteristics of the fishing gear.
