The North Yamaska river is a tributary of the Yamaska river. It flows over 47.8 kilometres (29.7 mi) on the south shore of the Saint Lawrence river in Quebec, Canada and passes through five municipalities, some of them sourcing their fresh water from it.
Pogonichthyinae is a subfamily of the freshwater fish family Leuciscidae, which contains the true minnows. Members of this family are known as American minnows or the North American (NA) clade of minnows. As the name suggests, all members of this family are found in North America (although they are not the only minnows native to North America, as Plagopterinae, Laviniinae, and Leuciscinae are also found there).
