About This Fish Guide
This comprehensive US freshwater fish guide covers the most common and popular sport fish species found in American lakes, rivers, and reservoirs. Each species profile includes detailed information on identification, habitat preferences, optimal water temperatures, proven fishing techniques, and where to find them across all 50 states.
Water temperature is one of the most critical factors determining fishing success. Fish are cold-blooded, meaning their activity levels, feeding behavior, and location in the water column are directly controlled by temperature. Use the temperature filter above to find species that are currently active based on your lake or river's current water temperature — which you can find on any water body detail page on this site.
Always ensure you have the appropriate state fishing license before fishing, and check local regulations for size and bag limits for each species. Fishing regulations vary significantly by state, water body, and season.
