Learn how to interpret the fish descriptions and distribution maps used to describe the freshwater fishes of Connecticut!
True to their names, sticklebacks have very sharp spines, which can be locked in an upright position, causing these little fish to be very unpalatable for most predators.
A popular baitfish, fathead minnows can be found at low abundance almost anywhere in Connecticut.
