During 45 sampling days between April 14 and November 6, 1986, 810 cutthroat trout were tagged in the upper Lakelse River near Terrace, B.C. The majority were age four (34.3 percent) and five
(25.4 percent), followed by three, six and two year olds at 17.6, 4.9 and 3.9 percent respectively. Repeat spawners comprised 13.7 percent of the
sample. Average fork length of two, three, four, five and six year old cutthroats were 195, 235, 285, 355 and 385 mm respectively. A single seven year old fish was 420 nun. Cutthroat abundance during the study period was roughly estimated at 7000 fish (confidence limits 4977 to 21579). Tentative conclusions, based on both age compositions and
abundance estimates obtained during this and earlier studies, suggest a stable cutthroat trout population. A consistent evaluation of the Lakelse Lake and or River cutthroat trout population should be developed.
