Lake trout are the primary focus of management in Cruiser Lake. The first recorded stocking of lake trout occurred in 1948 when 21,000 fry were introduced. Stocking continued until 1988. The 2005 assessment was designed to target the lake trout population. Lake trout, white suckers, and yellow perch were the only three species captured in the 2005 assessment. Lake trout was the most common species, making up 80% of the catch by number. Lake trout gill-net abundance in 2005 was 5.8 fish/set, which was slightly higher than the historical mean for the lake (4.5) and much higher than most class 3 lakes. None of the lake trout captured had fin clips, which were given to stocked lake trout. Furthermore, age analysis indicated that all fish were from year-classes that occurred after stocking ceased. Many year-classes were present, including fish up to 12 years old. Total length ranged from 10.2 to 20.7 inches with a mean of 15.9. Mean weight was 1.34 pounds, which was much lower than most class 3 lakes.
