“…The abundance of reproductive males is a good indicator of the reproduction state of a population (Huner and Romaire, 1979), and positive correlations among the abundance of Form I males and mature females were found by Alcorlo et al (2008). In our study, the abundance of reproductive males was highly synchronous with the increase of female's maturation index.…”

“…PMG is a permanent rice field channel with an average depth of approximately 0.44 m and its higher conductivity values do not indicate a factor of stress because the species is tolerant to brackish water with salinities up to 10 ppt (Huner, 1988). In fact, Alcorlo et al (2008) sampled crayfish from 11 stations in the Lower Guadalquivir basin (Spain) with conductivities ranging from 1000 to 4000 mS.cm x1 in rice field and channel habitats.…”

-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.

“…The natural hydropattern and seasonal functioning of the Lake Trasimeno have been drastically altered by the excessive drawdown of water for urban and agricultural uses over the past half century. It is known that changes in hydropatterns can affect some population properties, such as for P. clarkii in Spain (Alcorlo et al, 2008) and Portugal (Anastácio et al, 2009). There is considerable scope for further work on the influence of environmental factors on the life history of non-indigenous crayfish species.…”

Understanding population dynamics and regulation is fundamental for predicting establishment and spread of invasive alien species. In addition, the population biology of invasive alien species offers an opportunity to study basic ecological processes. In this context, we investigated reproductive and growth plasticity in the invasive crayfish Procambarus clarkii in Lake Trasimeno (central Italy). In total, 3153 crayfish were collected monthly from June 2007 to July 2009. The molt status was assessed by evaluating the exoskeleton hardness. To assess the reproductive cycle, the gonado-somatic and wet hepato-somatic indices were calculated for females. The reproductive status of males was appraised as well. We estimated growth and longevity using the von Bertalanffy growth function, and calculated the total, natural and fishing mortality indices. We then compared our present data with those obtained from the same population eight years before. Our results indicate some changes in population dynamics and in both molting and reproductive periods since the initial invasion of the shallow lake investigated. Long-term differences in the life history of the Trasimeno population may be the result of selective pressures different from those of the native range, but may also result from colonization events and human interference caused by professional fishing activities.

“…The number of eggs per brood may reach up to 700 (Penn, 1943;Noblitt et al, 1995) although it depends on female size and is also related to water temperature, population density and the length of the hydroperiod (Alcorlo et al, 2008). The embryonic development time depends on atmospheric temperature and may be inhibited under 10 ºC (Sukô, 1953).…”

“…In Procambarus clarkii, mating period, as well as recruitment and sexual maturation, vary according to hydrographic period and environmental conditions (Sommer, 1984;Alcorlo et al, 2008) and therefore, due to the combined effects of these factors, reproduction may change after the species is introduced into different regions. Reproduction is regulated by pheromones perceived by receptors located on the antennae which are responsible for interspecific and intraspecific recognition and behavioural modulation (Ameyaw-Akumfi and Hazlet, 1975).…”

Red swamp crayfish: biology, ecology and invasion - an overview

-Alien species have been transported and traded by humans for many centuries. However, with the era of globalization, biological invasions have reached notable magnitudes. Currently, introduction of alien species is one of the major threats to biodiversity and ecosystem functioning. The North American crayfish Procambarus clarkii is one of the most widely introduced freshwater species in the world, especially due to its high economic importance. It is responsible for great modifications in invaded environments causing irreparable ecological and economic damages. Its impressive ability to successfully colonize a wide range of environments is a consequence of its behavioural and biological characteristics that can adapt to features of the invaded location, conferring to this species a notable ecological plasticity. This review summarizes the available information regarding P. clarkii's biology and invasive dynamics around the world in order to contribute to the understanding of the threats posed by its establishment, as well as to support management and impact mitigation efforts.
