The more knowledge you have about the different types of freshwater fish habitats and feeding habits, the better an angler you can become, and you will be better equipped to follow the state fishing laws and regulations for each species.

Warmwater, Coldwater, and Coolwater Species

Freshwater fish species are generally separated into one of three different categories (warmwater, coldwater or coolwater) based on water temperature and the associated amount of oxygen in the water at each temperature range. For example, cold water holds more oxygen than warm water, which means coldwater fish will require higher oxygen levels in order to survive.

Warmwater fish species: These fish can live in a wide range of conditions. Largemouth bass, bluegill, catfish, crappies and sunfish are all considered warmwater species. Although they can survive cold winters in the northern states and can be found throughout most of the U.S., warmwater species will thrive best when water temperatures are around 80 degrees Fahrenheit.

Coldwater fish species: As you might imagine, coldwater fish species require cold water temperatures in order to survive. Brook trout, rainbow trout, and brown trout are three of the most popular species of coldwater game fish; however, you will notice that these species are limited to the northern U.S. or to areas of high elevation where air temperatures can support the colder water. Coldwater species prefer water temperatures that are in the 50 to 60 degree Fahrenheit range.

Coolwater fish species: The third category of freshwater fish is the coolwater species category. Muskellunge, northern pike, walleye, and yellow perch are among the most common coolwater game fish species. These fish prefer water temperatures in-between the other two categories. Because these species grow best in water temperatures that range in the 60's and 70's, they are most often found in the northern and midwestern states.
