Freshwater fish are all cold-blooded species. This means their internal temperature and functioning are affected by the temperature of their surroundings since they are unable to maintain a steady body temperature, unlike humans and other warm-blooded creatures. This has an immediate effect on their overall activity levels as well as when and how much they eat.

Fish can be further divided into species found in cold, cool, and warm water based on their preferred temperature. In our case, the primary species we fish for are walleye and pike, which are known to inhabit cool waters. These cool water species are eager biters during the spring and fall seasons, when lower water temperatures are more accurate to their thermal preferences. The best temperature range for these fish are 55-75°F for pike and 53-72°F for walleye but the best individual temps lie in the middle of the range.
