Agonistic encounters in competition for space, shelter, and access to mates or food are very common in crustaceans and have been studied extensively in different orders and families (Dingle, 1983; Hyatt, 1983) such as mantis shrimp (Stomatopoda; Caldwell and Dingle, 1975), freshwater prawns (Palaemonidae; Barki et al., 1991), lobsters (Homaridae; Huber and Kravitz, 1995), crayfish (Astacidae
, Cambaridae and Parastacidae; Copp, 1986; Soderback, 1991; Pavey and Fielder, 1996), and hermit crabs (Paguridae; Elwood and Neil 1992).
Esta condicion ha sido reportada tambien para otros decapodos como Astacidae
(Rudolph, 1997; Zou & Fingerman, 2000; Pinn et al., 2001; Turra, 2004; Vazquez & Lopez-Greco, 2007).

The North American crayfish belong to two families, Astacidae
and Cambaridae with all members east of the Mississippi River belong to the family Cambaridae (Hobbs 1974a).
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.
