Bruce - If Bender gets 82F water he won't be raising any trout.
I would Keep feeding in the pond with YP and BG as long as the BG are eating. If it is too warm for YP they won't eat. My YP eat well even when water temps are in high 80's, although quanitity eaten drops off. I think the smaller fish (9"-13") are primarily the ones eating the most in mid to high 80F water. Largest ones slack way off in feeding during July - August.
I have been told that the YP typically accumulate all their necessary fat for the next spawn buy July 1st. Additional feeding is primarily for maintenance. I am not sure how this applies to aquaculture conditions and raising for accelerated growth. Ultimately it probabaly shortenes their life spans due to fat and cholesterol accumulations from improper diets.
