The 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...
متن کاملJuvenile plaice (Pleuronectes platessa) produce camouflage by flexibly combining two separate patterns.
Plaice (Pleuronectes platessa) is a flatfish well-known for the ability to vary its body pattern, probably for camouflage. This study investigates the repertoire of patterns used by juvenile plaice, by describing how they respond to shifts between three artificial backgrounds. Two basic patterns are under active control, fine ;spots' and coarser 'blotches'. These patterns are superimposed on a ...
متن کاملRelating plaice (Pleuronectes platessa) recruitment to deteriorating habitat quality: effects of macroalgal blooms in coastal nursery grounds
Concentration of juveniles of marine fishes in nurseries may act as a bottleneck during the life cycle, where quantity and quality of nurseries determine population size. Macroalgal blooms have become a common phenomenon in eutrophic shallow waters worldwide, and matforming algae may now cover many essential nursery habitats. In this investigation, the aim was to assess the quantitative effect ...
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 کاملReconstructing 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...
