Rainbow trout grow best in the water temperature range from 55 ' to 68 ' F, but can not survive prolonged periods of temperatures above 70' F. Consequently, it is best to stock the trout shortly after the water temperature drops below 70 F to take advantage of the warm fall temperatures when growth will be rapid. Creel Census Census data were used to estimate fishing effort (angler trips), pressure (angler hours), total salmonid harvest, rainbow trout CPUE, rainbow trout harvest and condition coefficient by strain and cohort. This table is generally more accurate for “wild” Rainbow Trout, but give or take a few 100 grams and this can be applied to stocked fish, and their weights are very similar to Brown Trout, generally at each length a Brown Trout will be 10 to 60 grams heavier.
