What do fish eat in the winter?
Fish metabolism slows because of cooling water temperatures, and since food availability is greatly reduced in winter, this is an effective survival mechanism. With lower production of stream invertebrates, many trout shift to eating drifting insects. The goal is to expend minimal energy to catch their food.
