Pectoral fins

Pectoral fins

Brown and rainbow trout differ markedly in their coloration. More subtle differences include the size of their pectoral fins. Brown trout (top), which are adapted to flowing water, have larger pectoral fins which they use to keep them near the river bottom, where the current is slower. Rainbow trout (bottom) are predominantly lake fish that run upriver to spawn. Their pectoral fins are smaller: adapted to living in a lake environment, they do not need to use their pectoral fins to hug the riverbed.
