In a WWF reserve of south-western Sicily (Italy), a population of Procambarus clarkii has colonized the important protected areas of Preola Lake and the Gorghi Tondi Nature Reserve.Surveys were conducted in four lakes to investigate the structure and dynamics of the population inhabiting these lakes, and the life history patterns of this crayfish in this characteristic habitat are presented. Significant differences between sex ratio and cephalothorax mean measurements) were not evidenced. The population's parameters were estimated using the Von Bertalanffy growth function and the Bhattacharya method. Similarly to previous work, this study it was found that this species has a lower growth rate and longevity in comparison with other populations living in the Mediterranean region (approximately 4 years old). The spatial analysis evidences a strong heterogeneity and large movement range of the specimens during the study period. The results indicate the high ecological plasticity of Procambarus clarkii, suggesting the importance of monitoring this bio-invader to plan appropriate actions for the control of this population in protected areas where it occurs to preserve the local biodiversity.

“…The use of traps with entrances at the top is motivated by the fact that it will limit the capture of non-target species but the higher this type of trap is, the more difficult it is to catch crayfish. The large proportion of small individuals observed in SCG whatever the habitats (51.1 to 82.3%), at this stage of the life cycle of the species, likely reflected the real population structure of P. clarkii better (see also Correia, 1995;Anastácio et al, 2009). Indeed, P. clarkii exhibits properties of an r-selected species, including particularly high fertility (Gherardi, 2006), and, in the present study, large proportions of small individuals were found only when SCG were used.…”

“…Rodríguez et al, 2003;Ilhéu et al, 2007;Correia and Anastácio, 2008;Matsuzaki et al, 2009), there is a need to better understand and predict the ecological success of the species, and therefore its impact on ecosystems. For this, an investigation of the environmental factors influencing the population characteristics of P. clarkii is a good starting point and will be helpful in the development of ways to control the species (Alcorlo et al, 2008;Anastácio et al, 2009). Trapping is likely to be the most useful method for sampling active P. clarkii (Huner, 1988) since the species inhabits aquatic ecosystems which usually have turbid waters thus limiting the efficiency of techniques such as manual search, night viewing and electro-fishing.…”

Key-words:catch-per-unit effort, length-frequency distribution, Procambarus clarkii, sampling method, trappingThe ecological importance of the red-swamp crayfish (Procambarus clarkii) in the functioning of freshwater aquatic ecosystems is becoming more evident. It is important to know the limitations of sampling methods targeting this species, because accurate determination of population characteristics is required for predicting the ecological success of P. clarkii and its potential impacts on invaded ecosystems. In the current study, we addressed the question of trap efficiency by comparing population structure provided by eight trap devices (varying in number and position of entrances, mesh size, trap size and construction materials) in three habitats (a pond, a reed bed and a grassland) in a French marsh in spring 2010. Based on a large collection of P. clarkii (n = 2091, 272 and 213 respectively in the pond, reed bed and grassland habitats), we found that semicylindrical traps made from 5.5 mm mesh galvanized steel wire (SCG) were the most efficient in terms of catch probability (96.7-100% compared to 15.7-82.8% depending on trap types and habitats) and catchper-unit effort (CPUE: 15.3, 6.0 and 5.1 crayfish·trap −1 ·24 h −1 compared to 0.2−4.4, 2.9 and 1.7 crayfish·trap −1 ·24 h −1 by the other types of fishing gear in the pond, reed bed and grassland respectively). The SCG trap was also the most effective for sampling all size classes, especially small individuals (carapace length 30 mm). Sex ratio was balanced in all cases. SCG could be considered as appropriate trapping gear to likely give more realistic information about P. clarkii population characteristics than many other trap types. Further investigation is needed to assess the catching effort required for ultimately proposing a standardised sampling method in a large range of habitats. −1 ·24 h −1 trouvées dans les autres pièges respectivement dans le plan d'eau, la roselière et la prairie inondée). Les pièges SCG étaient également les plus efficaces pour échantillonner toutes les classes de taille, et particulièrement les petites écrevisses (longueur de carapace 30 mm). Le sexe ratio était équilibré dans tous les cas. Les pièges SCG pourraient être considérés comme un engin de pêche approprié pour fournir des informations probablement plus réalistes sur les caractéristiques de populations de P. clarkii que de nombreux autres types de piège. Des études supplémentaires sont nécessaires afin d'évaluer l'effort d'échantillonnage requis pour finalement proposer une méthode d'échantillonnage standardisée dans une large gamme d'habitats.

“…It has been described that under certain circumstances this may also affect dispersion patterns (Gherardi and Barbaresi, 2000;Light, 2003). P. clarkii main recruitment period in Portugal is usually in September/October (Anastácio and Marques, 1995;Anastácio et al, 2009) and mating is during May-July. Although no differences in reproductive form were perceptible among 2010 and 2013 individuals, the 2013 tracking period was just after the usual mating period.…”

a b s t r a c tRed swamp crayfish (Procambarus clarkii) and signal crayfish (Pacifastacus leniusculus) are two invasive freshwater species with a worldwide distribution. The objective of this work was to investigate how the two species move and use space in an area of recent coexistence. Simultaneously, we test the use of new tools and indices to describe their movement patterns. To accomplish this we performed a radiotracking program within a river-type habitat during two different periods (September/October 2010 and June/July 2013). We used spatial analysis tools to map crayfish radio-location data with and without accounting for the curvature of the river. To assess the consistency of the direction of movement and of the distances traveled by crayfish, two indices were developed. To assess the habitat preferences of each species we applied Ivlev's Electivity Index and the Standardized Forage Ratio. Movement of P. clarkii and P. leniusculus differed. The average detected movement was 8.8 m day −1 for P. clarkii and 17.5 m day −1 for P. leniusculus. However, crayfish behavior ranged from almost complete immobility -sometimes during several days -to large movements, in half a day, up to a maximum of 255 m for P. clarkii and 461 m for P. leniusculus. The proportion of upstream or downstream movements was independent of the species and both species displayed no preference for either direction. The indices of consistency of movement showed a large interindividual variation. Species and period (2010 or 2013) affected the mean daily distance traveled, maximum observed distance from location of release and percentage of observations under vegetation cover. The Ivlev's Electivity Index and the Standardized Forage Ratio presented similar results. P. clarkii showed a preference for pool areas with riparian vegetation cover while P. leniusculus preferred riffle and pool areas with riparian vegetation cover. Our work provided new and valuable data for modeling the active dispersal of these two problematic invaders in a context of coexistence.
