Being up in Ontario, I am unable to get the food used in the States. I feed my fish Martin's which is actually local for me (15 minutes away) so I can go right to the plant and buy saving me paying the middle man! They supply ALOT of food trout food to the big comercial operations growing rainbows up in Georgian Bay as well as the little guys like me! I have had nothing but good luck with there food
Here is a link to there website- http://www.martinmills.com/profishentIndex.asp

This year I had a bunch of last years browns die on me and all of the remaining brookies but I had my aerators shut down on me when I was on vacation in the hottest part of the summer (last week of July) and caused a D/O crash.

I was told by the supplier of these fish that I should stop feeding in my pond in late May/Early July and don't feed again until September. My pond is mainly ground source water (its on the top side ofi a peat bog) He said that he had a few customers loose trout from feeding in the summer, and once they quite feeding like that they would make it over the summer every time up here...even the brookies!

Next year I am also going to add 2 large floating rafts (10x10 or bigger) which will make for some great shade and give them a place to hide in the heat of the day other than just my current dock.
