Current data suggests that the Procambarus virginalis is a fast-growing species that exhibits r-selected life history traits like early maturation, an extended breeding period, and high fecundity, giving it a competitive advantage over other species.

Results of a competition experiment suggests that marbled crayfish Procambarus virginalis dominates in interactions with red swamp crayfish P. clarkii. Marbled crayfish won significantly more fights and established dominance more frequently in both mature and premature trials.

Results of a dynamic energy budget model suggest that marbled crayfish is a superior competitor when considering metabolism and ontogeny. Models show that marbled crayfish has a clear potential to be a better competitor than Astacus astacus, Austropotamobius torrentium, and Pacifastacus leniusculus.

Analysis of three co-existing crayfish populations suggests that the marbled crayfish (Procambarus virginalis) and spinycheek crayfish (Faxonius limosus) trophic niches overlap, indicative of competition. Results also indicate likely competition for food with the red swamp crayfish (P. clarkii).

Experimental studies were conducted to examine agonistic interactions between signal crayfish (Pacifastacus leniusculus), common yabby (Cherax destructor), and marbled crayfish (Procambarus virginalis). The marbled crayfish was the least aggressive and least successful in agonistic interactions. However, other factors such as growth rate and reproductive potential may alter competitive interactions in favor of marbled crayfish.

Marbled crayfish has shown competitive dominance over calico crayfish (Faxonius immunis) in experimental lab studies. When no shelter was available, marbled crayfish won significantly more fights. With available shelter, marbled crayfish dominance was 100% for female and 54.5% for male calico crayfish.

Marbled crayfish (Procambarus virginalis) and round goby (Neogobius melanostomus) are expected to compete for shelter in areas where they co-occur. Competition is expected to be strongest during the daylight hours.
