to implement fish in the river to increase fishing as a sport. The main fish cruising its waters are white sucker (Castostomus commersonii) and Cyprinidae; more polluted areas are occupied by brown bullhead (Ameiurus nebulosus). Species sought after for fishing include muskellunge (Esox masquinongy), Esox, black bass (Micropterus sp.), Sander, yellow perch (Perca flavescens), pumpkinseed (Lepomis gibbosus) and mud cat. Over the years the species added to the river for increase sport are the brown trout (Salmo trutta), rainbow trout (Oncorynchus mykiss), muskellunge, Sander, yellow perch, brown bullhead, smallmouth bass (Micropterus dolomieu), and brook trout (Salvelinus fontinalis). Inventories carried at Mont Yamaska allowed to observe over fifteen species of amphibians and even reptiles (such as the painted turtle (Chrysemys picta) and Common Garter Snake (Thamnophis sirtalis)). Common amphibians inventoried in the river are the dusky salamander (Desmognathus fucus), wood frog (Rana sylvatica), and the green frog (Rana clamitans). The Baie Lavalilière (Sainte-Anne-de-Sorel, Québec), located near the mouth of the river, is considered a very rich habitat for amphibians, although poaching of bullfrog (Rana catesbeiana), northern leopard frog (Rana pipiens), and green frog limit their population. Citizen Collective Art Movement 11 May 2013 saw the inauguration of two collective artworks "URGENCE YAMASKA" (Yamaska Emergency) and "LA YAMASKA, C'EST NOUS..." (The Yamaska, it is us...), during the community art project Art-Yamaska; the art is said to be issue of a collective reflection about the river's health and depicts several clear environmental messages. The project aims education of ecological awareness linked to the Yamaska's health. Along with the artwork's public exposition on Granby's water pumping station, the project included poetry reading, a photography exposition, and several mural and mosaic workshops, culminating in festivities on the river's celebration day in 2013. Since their installment, the collective murals have gained much renown and visibility due to their location just off a popular cycling network (a large portion of it within meters of the river). In May 2015, a new artful message followed in the Art-Yamaska project with the creation of "Qu'es-tu devenu Yamaska?" (What have you become, Yamaska?) a few kilometers downstream the same cycling track as the previous mural. Once more, workshops were organized by the art and creativity non-profit organization Atelier 19 to allow a group of youth to invent an environmental message to be posted underneath and on the sides of Patrick-Hackett bridge; the place is famous for its vandalism in the
