Colorado Fish Species



There are many fish species in Colorado. The different species of fish you can catch are listed below. Trout are the most popular game fish native to Colorado and can be caught in almost every body of water in the state. The elevation of the bodies of water and mean temperatures surrounding them make Colorado waters ideal habitat for big trout. Most warm water species liek bass, walleye and bluegill are largely introduced and not the focus of many guide service. Blue Mesa Fishing Guide Network runs guide trips on many lakes and targets the cold water species. You can learn how to fish for all of these fish in Colorado through our information guide Service, but we do not guide for Pike, any bass species or walleye. The Colorado fish species we guide for don't vary too much between lakes, rivers and altitude. Trout and salmon are the main focus but its good to know all the species you can catch. Each Colorado fish has its own thresh hold and desired environment which changes drastically around the state. Fortunately the species of fish that can be found and survive in almost all bodies of water are the Rainbow Trout. Read below to see all the species found in Colorado and Blue Mesa Reservoir!
