That is a health question, and it is answered officially rather than by us.

What size fish can you keep in Colorado?

It depends on the species, and several have slot limits rather than a simple minimum. Open to harvest today: trout, arctic char, grayling and mountain whitefish, kokanee salmon, walleye, saugeye and sauger, largemouth, smallmouth and spotted bass. Seasons here change mid-year by agency order, so the status is re-checked every morning.
