Quelques données sur la croissance, la biomasse et la production annuelle de trois mollusques Unionidae de la région de Montréal

Three species of Unionidae, Elliptio complanatus (Solander), E. dilatatus (Rafinesque), and Lampsilis radiata (Gmelin), collected from Lake des Deux Montagnes and Lake St. Louis were used to estimate relative numbers, population density, shell growth, growth in weight, longevity, standing crop, and production. These parameters were compared between the species in each lake and between the populations of the two lakes. Comparisons with the data of other workers on other species are also included.
