WOW 🤩 Meet the River Chub! Mature males develop a big pink head decorated with tubercles during the spawning season. It's not just their looks that will catch your eye, but also their nest building behavior! These fish move thousands of rocks to build a suitable spawning mound. What's REALLY cool is other smaller species, like the Mountain Redbelly Dace, won't spawn without the presence of a River Chub nest, making this species and other chubs in the Nocomis genus very important indeed. 🐟 Learn all about this fish on our latest "Fish of the Week" episode (available on our FWS website or wherever you get your podcasts). 🎣 A mature male River Chub. 📷 Charlie Mellor CC-by-NC 4.0 #AllTheFish #NativeFish #Fishing
