Trout may not hibernate like bears, but it sure can seem that way if you have ever gone fishing in cold waters. Trout are cold blooded and slow down everything that they do in the winter months. They will once again become a lot more active as the water begins to warm in the spring, as do the insects that they regularly eat. While spring, summer and fall are quite different in their own right, each season has insects and fish that are active and making things happen.
Winter is entirely different.
