ive always called em chubs. the horns on the head get bigger as they grow. you will catch them ALL the time if you worm fish up in the mountains lol. seriously...its like 10 chubs to every trout you catch lol.
this time of year u will see where they pile up a small rock pile in pool in the creek& spawn after thatyou will see the fry they will be orange in color ever once in awhile will see where a big trout or redeye has ran thru the rock pile chasing those fry
