Musreau Lake Rainbow Trout (Onchorychus mykiss) Status Report 1998


Paul Hvenegaard and David Fairless


Musreau Lake was stocked with approximately 200,000 “marked” rainbow trout in the fall of 1997. Escapement from the lake via the outlet, Musreau Creek, was examined with a fish fence and electrofishing. A systematic gillnetting program was implemented to determine survival in the lake. Escapement was determined to be negligible and survival was estimated to be poor as only 3 and 6 marked fish were recovered in the creek and lake respectively.

The late fall nocturnal stocking strategy appeared to prevent escapement but had a neutral effect on survival. Further investigations into the precise cause of low survival of stocked trout are required.
