Catostomus commersonii

There are several species of suckers in the Hudson’s watershed, but the one we commonly catch in the tidal river is the white sucker. It can grow to a length of over twenty inches. The white sucker is found in fresh water where it feeds on the bottom with a specially adapted, vacuum cleaner-like mouth. These fish make spawning runs up into the Hudson’s tributaries during the spring.
