Thanks for the information. I just measured out how many jars of food 3/4 lb is, and I will be feeding that daily. I been disappointed with absolutely zero feeding response in the past few days. It happened suddenly after we had a cold front and the water temperatures dropped about 5 celcius. I guess temperature changes really effect the fish in the pond in terms of their activity.
I've found the same thing. However, rainbow trout will often increase feeding response when temps fall, while LMB and CNBG lose interest.
