Growth and Mortality of 0-Group Plaice 'Pleuronectes Platessa' L. in DutchCoastal Waters

摘要

Growth and mortality of O-group plaice (Pleuronectes platessa L.) was studied inthe open coastal zone along the isle of Texel between March and October in 1992 and compared with estimates of estuarine nursery areas (Balgzand area, Wadden Seat), to test the following hypotheses: Mortality of O-group plaice in open coastal nursery areas is higher than in the estuarine Wadden Sea, due to the presence of higher numbers of predators. Growth of O-group plaice in open coastal nursery areas is lower than in the estuarine Wadden Sea, due to more severe interspecific competition for food.
