“…Because water is limiting the system, crayfish can only reproduce and grow during a certain period and therefore the population adapts to these conditions. At PCD, recruitment occurred mainly after flooding, in November, which is similar to Central and Northern Portugal, Northern Italy and the United States (Huner and Barr, 1991;Anasta´cio and Marques, 1998;Gherardi et al, 2000;Fidalgo et al, 2001;Mueller, 2007). At PMG, recruitment occurred throughout most of the year but with two main seasons: The first was from spring to early summer and the second during November-December.…”

-The population dynamics of the red swamp crayfish (Procambarus clarkii Girard, 1852) was studied from May 2005 to May 2006 in a pond (PCD) subjected to drought between June and December and in a continuously flooded rice field drainage channel (PMG) located in the Tejo river basin, Portugal. The proportion of females in the population was not independent from the season and was negatively correlated with both female and male maturation status. Male and female maturation was synchronous but males remained in a reproductive form after recruitment while females reverted quickly to lower maturation indexes. At PCD and PMG, respectively 2 and 5 cohorts were detected by modal analysis. Large crayfish were abundant in spring, summer and early autumn and juveniles were abundant in autumn, especially at PCD. Crayfish density at PCD was lower than at PMG and mortality rate (Z) was 3.99 at PCD and 2.43 at PMG. The average lifespan of the crayfish populations was 91 days at PCD and 150 days at PMG. Our study indicated faster growth and larger maximum sizes at the site with the more stressed environment and lowest relative crayfish densities (PCD), suggesting that any exploitation or control strategies for these two populations should consider management of the hydroperiod and of maximum crayfish densities.

“…But red swamp crayfish is able to thrive also at cooler climates at higher latitudes and altitudes (Frutiger et al, 1999;Mueller, 2007b;Ellis and England, 2008). P. clarkii can survive, breed and grow in the climatic conditions of UK (Richter and Wiles, 2000), Germany (Dehus et al, 1999), Netherlands (Henttonen and Huner, 1999) or Switzerland (Stucki, 1997).…”

Key-words:Pacifastacus leniusculus, Procambarus clarkii, dispersal rate, crayfish coexistence NE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its northward expansion. The dispersion of both species was followed throughout the last decade in river Maçãs (Douro catchment). Our results support the hypothesis of faster downstream colonisation. The mean spread rate of signal crayfish was faster for the downstream expansion, 2.8 km·yr −1 , while the upstream rate was 1.7 km·yr −1 . Exceptionally, in one period, the rate of spread reached 6.7 km·yr −1 , which was apparently caused by downstream washing in extreme conditions of flow. The mean rate of spread is higher than the observed in other studies which may also be related to the low current velocity of late spring and summer that provides favourable conditions for a fast upstream colonisation. Coexistence of signal and red swamp crayfish was detected in a large river sector. Signal crayfish strongly dominates in the upper and intermediate sectors which are the colder part of the river and in the lower sectors, species abundances are not significantly different. Winter temperature in the higher altitude reaches seems to moderate the competitive abilities of P. clarkii. plus rapide en aval, soit 2,8 km par an, comparé à 1,7 km par an en amont. Exceptionnellement, sur une période, le niveau de colonisation a atteint 6,7 km par an car les écrevisses on été apparemment emportées en aval à cause des conditions extrêmes d'écoulement. La propagation moyenne est plus élevée que ce qui est observé dans d'autres études, ce qui peut être mis en relation avec la faible vitesse du courant en fin de printemps et en été, favorisant une colonisation rapide en amont. La coexistence de l'écrevisse signal et de l'écrevisse rouge a été observée dans une grande partie de la rivière. L'écrevisse signal domine dans la partie haute et plus froide de la rivière, alors que dans le secteur le plus bas il n'y a pas de différence significative entre les deux espèces. La température hivernale, observée en plus haute altitude, semble modérer les capacités de compétition de P. clarkii. RÉSUMÉ

“…Procambarus clarkii typically reaches sexual maturity at -40 mm CL and mates during summer, a period when reproductive adults, especially females, often seek shelter in burrows (Gherardi et al 1999, Ilheu et al 2003, Penn 1943. In Pine Lake, the reproductive cycle of P. clarkii is similar to the pattern reported for many populations of the species (Mueller 2007a). During the enclosure experiments, the size of winning P. clarkii was typically 240 mm CL.…”

“…If the non-native P. clarkii is indeed displacing the native P. leniusculus at Pine Lake a s reported by Mueller (2007b), the results of the present study suggest that additional mechanisms besides shelter competition are likely contributing to the process. Some examples of possible mechanisms include competition for food (Hill and Lodge 1999), interaction at juvenile life stages (Mather and Stein 1993), and differences in life history strategies (Gherardi 2006, Mueller 2007a. Indirect facilitation effects are another.…”

“…In 2000, P. clarkii was discovered in Pine lake, a small lake in Sarnmamish, Washington (Mueller 2001). Subsequent survey work revealed that P. clarkii was actively reproducing (Mueller 2007a). Moreover, catch data suggested that the invader outnumbered the native signal crayfish (Paciyastacus leniusculus, Astacidae) by more than two to one.…”

Sheltering ability does not appear to confer an advantage to non-native red swamp crayfish (Procambarus clarkil) in a small, western Washington lake where the invader outnumbers the native signal crayfish (Pacifastacus leniusculus). When paired with similar-sized non-native P. clarkii, P. leniusculus was adept a t monopolizing limited artificial shelter inside enclosures placed on the bottom of Pine Lake. In these contests, the dominant crayfish or winner was typically the one with longer chelae, or, in the case of P.clarkii, the one that was sexually mature. Female crayfishes of both species also were adept at monopolizing the artificial shelter. Furthermore, irrespective of species and sex, when paired with smaller heterospecifics, large crayfish readily monopolized the artificial shelter. These results suggest that additional mechanisms besides shelter competition are contributing to the possible displacement of P. leniusculus in Pine Lake.
