Aspects saisonniers de la fixation de l’épifaune benthique de l’étage infralittoral de l’estuaire du Saint-Laurent
This work conducted during two seasons (May–October 1969, 1970) was designed to study the dynamic aspects of the settlement of benthic epifauna on hard substrata. The stations were distributed on a 200-km distance, the salinity gradient ranging from 15 to 27‰. Although over 60 species were identifie...
