摘要:

A preliminary survey of the Arctic char (Salvelinus alpinus) in the vicinity of Term Point, N.W.T. on the west coast of Hudson Bay, was carried out from August 12 to September 13, 1948, to augment the biological data pertaining to this species and assess its importance in the area studied. Information relative to the rate of growth, food and spawning habits of sea-run arid landlocked populations was obtained. The dependence of the Eskimo residents on this species as a food coupled with the limited supply would seem to preclude the establishment of a commercial char fishery in this area.

摘要:

An investigation of the Loudoun Channel area of Barkley Sound was carried out in April 1950 to determine the currents, net transports, and oceanographic conditions in the vicinity of the herring spawning grounds. Currents were measured at anchor stations by means of captive floats. Serial observations of salinity and temperature were made both at the anchor stations and in synoptic surveys of the region. Evidence was found that a significant change in the pattern of flow occurred between the earlier and later parts of the month which appeared to be associated with a sudden increase in the rate of discharge of the Somas River in nearby Alberni Inlet.
