Lake trout sample count


Today we completed our monthly sample count for Lake Trout. First, the Biologists scoop fish into a bucket. Next, they measure the total weight of fish and number of fish in the bucket. This allows the biologists to calculate an approximate weight per fish. This process is completed three times then averaged. The weight per fish calculation allows the Biologists to calculate feed rates and growth rates for the Lake Trout in each raceway.
