The Movement of Tagged Great Slave Lake Fish
At Great Slave Lake, N.W.T., 3629 fish marked with Petersen tags were released during 5 years from 1946 to 1955. The time at large and movement of 505 recoveries, mostly lake whitefish, Coregonus clupeaformis, and lake trout, Cristivomer namaycush, are analyzed. Most of the tagged fish were caught i...

| Summary: | At Great Slave Lake, N.W.T., 3629 fish marked with Petersen tags were released during 5 years from 1946 to 1955. The time at large and movement of 505 recoveries, mostly lake whitefish, Coregonus clupeaformis, and lake trout, Cristivomer namaycush, are analyzed. Most of the tagged fish were caught in the summer commercial fishery; returns during the fall and winter were scarce. The median recapture time was 268 days; the maximum, for a lake trout, was 4027 days. Movement was generally limited; its median was 5 statute miles (8 km). A few fish travelled relatively long distances. There was no overall directional pattern to the movement, but some aggregation of the recaptured fish was noted. The fish populations are regarded as sedentary rather than mobile. |
