Vue d'ensemble

Jeux de données : (1) number of recaptures on the tagging sites for sturgeon recaptured more than once [these data relate to fish tagged on sites which are not spawning grounds], 1981-1984; (2) distribution of recaptures by commercial fishermen [lake Saint-Pierre and Sorel-Berthier Islands, lake Saint-Louis; Laprairie basin]; (3) annual numbers of fish tagged and tag returns by commercial fishermen for sturgeon 800-1350 mm long; (4) annual harvest, yield, fishing success, mean weight, annual mortality per sectors [field data 1982-1984].***Raw data not included in the report.

Description du site
The study area extends from the western part of lake des Deux Montagnes, on the des Outaouais river, and lake Saint-François to the eastern part of the lake Saint-Pierre, including lake Saint-Louis and Laprairie basin, on the Saint-Laurent river. This area forms a complex network of rivers, channels and islands. Brown waters representative of the Precambrian Shield are dominant along the northern shore and green waters representative of the Great Lakes, along the southern shore.
Habitat
The lakes in the study area are actually enlargements of the river in which the water current velocity is generally moderate. Except in the navigation channel, depth is usually less than 6 m. More than 90 fish species have been identified in the study area. Although it suffers high degree of industrial and organic pollution, the study area remains productive for aquatic life because of its high dilution factor and the periodic presence of large rapids.
