  2. Introduction • Crawfish production is a major market in the U.S. • Red Swamp Crawfish—native to the lower Mississippi River Drainage. • Preferred habitat—swamps! • Food—decaying vegetation, aquatic plants, filamentous and attached algae and small benthic animals.

  3. Introduction • As water levels recede (early summer) crayfish burrow (Chimneys) • As water levels increase (Fall/Winter)—adults forage on decaying vegetation. • Wild crawfish are harvested with baited traps in the Spring. • Crawfish double-cropped with rice.

  4. General Crayfish Information • Adult size is 2" to 6" for most US species. Some Australian varieties can be much larger (Cherax quadracharanatus, Yabbi). • Growth occurs following molting or ecdysis (shedding of their carapace).

  5. General Crayfish Information • Nearly 150 spp. in N. America, >540 worldwide, but only several are cultured in this country. • Color and size varies with species, diet, and age. • Market value~$5/lbs. when in season.
