Rusty Crayfish ( Orconectes rusticus) DESCRIPTION: Rusty crayfish live in lakes, ponds and streams, preferring areas with rocks, logs and other debris in water bodies with clay, silt, sand or rocky bottoms. They typically inhabit permanent pools and fast moving streams of fresh, nutrient-rich water. Adults reach a maximum length of 4 inches. Males are larger than females upon maturity and both sexes have larger, heartier, claws than most native crayfish. Dark ârustyâ spots are usually apparent on either side of the carapace, but are not always present in all populations.
