Croissance de la plie rouge (Pseudopleuronectes americanus) de l'estuaire maritime du Saint-Laurent

摘要: A study on the growth in size and weight of Winter Flounder, Pseudopleuronectes americanus (Walbaum), was conducted from samples collected during summers 1979 1980, bay Saint-Fabien-sur-Mer (Quebec) south shore Lower St. Lawrence Estuary. Age determined by otolith readings length–weight relationships were calculated. Linear equations not statistically different for males females. On other hand, found to be higher females than equal sizes. This relationship also varies with sampling period, a substantial increase follows spawning period. The P. is slower estuary more southern areas, while weights at sizes are higher. These results reflect severe environmental conditions, which necessitate large accumulation food energy fish as reserves, detriment growth.
