Two specimens of the brook stickleback (Culaea inconstans) were taken in the mouths of Pierre and Tsital Trien creeks near Arctic Red River on the Mackenzie River during 1971. Previous most northerly published records were from the south shore of Great Slave Lake. The specimens may have been carried downstream by spring floods and may not represent a resident population.

A sequence of Upper Devonian echinoderm debris beds with graded texture, interbedded with shale, overlies the Middle Devonian Ramparts Formation in the subsurface at McDermott Canada GCO South Maida Creek G-56 well on the south side of Mackenzie River near Carcajou Ridge.The interval of echinoderm debris can be divided into thick 2- to 7-ft (0.6- to 2.1-m) beds of graded skeletal remains lacking shale, and thinner intervals from 1 to 2 ft (0.3 to 0.6 m) thick of graded skeletal remains with interbedded black shale. The echinoderm beds, not present in the subsurface at nearby wells, are probably of local origin. Similar beds of echinoderm debris with graded texture, also of probable local origin, crop out at Powell Creek in the Mackenzie Mountain foothills.

The Relationship

We found no significant differences in slope or intercept for the regression of loge fecundity on loge fork length among samples of whitefish from four lakes near Yellowknife in the Northwest Territories. The equation describing the relationship between fecundity and fork length for these populations was:[Formula: see text]Five other populations for which length–fecundity relationships could be calculated had length exponents ranging from 3.20 to 4.38, suggesting a nonlinear relationship between weight and fecundity. Six of the nine populations as well as four others for which limited data were available all had similar relative fecundities. Fish from Buck Lake in Alberta and from Lake Erie had high relative fecundities while fish from Great Slave Lake had low relative fecundity.
