That is something I will certainly try in the open water season. I'm really hoping to get some solid growth on the trout via feeding once the ice goes out. I am thinking the trout will stop eating in the middle of summer, since they will probably be at the bottom of the pond and less active. The water is not spring fed, so it does warm up. Luckily, we have never seen to have any heat related die offs.
I think April until mid June will be the key growing months, but I do wonder if they will eat during the warmest months.
