What type of fish ? General rule of thumb is low 50's water temp for warmwater fish (LMB , BG etc) a little cooler for coolwater fish like HSB , YP ,WE) and even lower for coldwater fish (pike , trout) . Some people even feed moist pelletes through the ice during winter in small amounts.
That's a question I always wondered about. Why do GB quit feeding on pellets when the water cools but they bite very well through the ice?
