Book Description
Sumerged aquatic plants limit the suitability for trout management of many shallow lakes in the Southwest. Control of these weeds has been achieved by the introduced crayfish Orconectes causeyi. The life history, ecology, and weed-control activities of the crayfish are discussed. Abundant crayfish populations occur over a wide range of elevations in permanent well-oxygenated ponds, lakes and streams where predaceous warm-water fishes are scarce. Weed control is proportional to the crayfish population and proximity of a rocky substrate which is preferred habitat. This crayfish is a tertiary burrower establishing relatively shallow burrows for hibernation and egg hatching periods. It has not damaged dams or irrigation ditches and has been compatible with local agriculture.
