An illustrated checklist of the American Crayfishes (Decapoda: Astacidae, Cambaridae
, and Parastacidae).
Male crayfish of the family Cambaridae
(including all Tennessee species) exhibit a cycle of dimorphism in which they alternate from a reproductively active stale in which their gonads have longer, more pointed terminal elements (form I) to a reproductively inactive state in which the gonads have shorter, more blunt terminal elements (form II) (Taylor and Schuster.
Freshwater crayfish aquaculture in North America, Europe, and Australia: families Astacidae, Cambaridae
, and Parastacidae.
Almost all crayfish in the United States occur east of the Continental Divide and comprise the family Cambaridae
(335 taxa), primarily in the genera Cambarus, Procambarus, and Orconectes.
The majority of the North American fauna (99%) is assigned to the family Cambaridae
with over two-thirds of its species endemic to the southeastern United States.

The crayfish family Cambaridae represents a large group of over 300 described and undescribed species in two subfamilies (Hobbs 1989).
Ten Cambaridae species were collected from the Patoka River drainage including members of each of the four Indiana crayfish genera (Tables 1, 2).
All crayfish in Indiana are members of the family Cambaridae, while the freshwater shrimp belong to Palaemonidae.

The 386 described species and subspecies of crayfish in North America are assigned to 12 genera in two families (Astacidae and Cambaridae); only Cambaridae occurs in this area.
Crayfish have been rated quite tolerant of some pollution, and Cambaridae have been rated somewhat pollution-tolerant (Table 2).
