Ségrégation édaphique et bathymétrique chez le crabe des neiges, Chionoecetes opilio (O. Fabr.), dans le sud-ouest du golfe du Saint-Laurent
A population of Chionoecetes opilio was studied during the summers of 1980 and 1981 in the southwestern Gulf of St. Lawrence, at the entrance of the Bay of Chaleur, and the Gaspé Bay. Sampling was conducted with beam trawls and baited traps at depths ranging from 45 to 125 m. Crab shell width of bot...
