Reconstructing the effects of fishing on life-history evolution in North Sea plaice Pleuronectes platessa
Growing evidence suggests that fishing may induce rapid contemporary evolution in certain life-history traits. This study analyzes fisheries-induced changes in life-history traits describing growth, maturation, and reproduction, using an individual-based eco-genetic model that captures both the population dynamics and changes in genetic trait values. The model was successfully calibrated to mat...
متن کاملEvolutionary impact assessment of the North Sea plaice fishery
There is growing evidence that fishing causes evolution in life-history traits that affect the productivity of fish stocks. Here we explore the impact of fisheries-induced evolution (FIE) on the productivity of North Sea plaice (Pleuronectes platessa) using an ecogenetic, individual-based model by comparing management scenarios with and without an evolutionary response. Under status-quo managem...
متن کاملKinematics of plaice, Pleuronectes platessa, and cod, Gadus morhua, swimming near the bottom.
The kinematics of plaice (Pleuronectes platessa, L=22.1 cm) and cod (Gadus morhua, L=25.0 cm, where L is total fish length) swimming at various speeds at the bottom and lifted to heights, h, of 10, 50 and 100 mm by a thin-wire grid were measured. For cod, tailbeat frequency, amplitude, body and fin span and propulsive wavelength were unaffected by h and varied with speed as described for fusifo...
متن کاملPerfluorooctane sulfonic acid in bib (Trisopterus luscus) and plaice (Pleuronectes platessa) from the Western Scheldt and the Belgian North Sea: distribution and biochemical effects.
A biomonitoring campaign was conducted in the Belgian North Sea and in the Western Scheldt (The Netherlands) with the primary goal to assess perfluorooctane sulfonic acid (PFOS) contamination and distribution in different biota. This study covers the results obtained for bib (Trisopterus luscus) and plaice (Pleuronectes platessa) and includes the assessment of some stress-related biochemical en...
متن کاملThe orientation of plaice larvae (Pleuronectes platessa L.) in water currents.
Bishai (i960) and Ryland (1963) studied the reactions of pelagic marine fish larvae to water currents and measured swimming speeds. They used glass tubes about 1-5 m. long with internal diameters respectively 1-2 and 175 cm. Neither author obtained a response to a striped background moving outside the tube, and Ryland concluded that plaice larvae did not respond to displacement of the visual fi...
