“…Dickson et al (1979) have shown that tissues from troglobitic crayfish (Orconectes australis) contained relatively high levels of cadmium although they inhabited a cave stream with lower concentrations (0.2 iAg/liter) than most in this study. No evidence of pesticides or polychlorinated biphenyls was found.…”

Extremely small population sizes, restrictive adaptations to the cave environment, over-collection and abuse of habitat threaten its existence. Careful protection of entire cave ecosystems and their aquifer recharge zones will be necessary to insure survival of this interesting species.

“…The physiological mechanisms to regulate the levels of this important metal are well developed in crayfish and apparently enable them to successfully cope with exposure to higher levels of copper in their environment without exhibiting tissue bioaccumulation. Dickson et al (1979) found that essential metals did not exhibit comprehensive species differences in tissue concentrations. The abdominal muscle did not demonstrate accumulation of any of the metals evaluated.…”

Red swamp crayfish (Procambarus clarkii) were placed for a period of 7 days in Bayou Trepagnier, a Louisiana waterway which received petroleum-laden effluents from a manufacturing complex several decades ago. However, coolant water from the plant continued to be released into the bayou until 1995. Analyses of sediments at the exposure site revealed heavy contamination by lead, chromium, and copper, while concentrations of arsenic and cadmium were very low. Significant bioaccumulation of lead was observed in the hepatopancreas and gills of 7-day-exposed crayfish, whereas chromium accumulated the most in the gills and blood. Concentrations of copper in the crayfish did not change during the course of the study, suggesting that this essential metal constituent of the respiratory pigment is successfully regulated even when crayfish are exposed to relatively high levels of copper in the sediments. There was no metal accumulation in the abdominal muscle of the crayfish. That damage to the hepatopancreas occurred during the exposure is suggested by histopathological studies which revealed swollen and vacuolated R cells and an increase in the pH of the digestive juices. Blood glucose levels, as well as ovarian and hepatopancreatic indices, were unchanged. This study demonstrates that accumulation of nonessential metals in crayfish tissues in a wetland environment contaminated by mixed pollution (metals and hydrocarbons) reflects the concentrations of metals in the sediment.

“…There have been numerous studies on the accumulation of heavy metals in crayfish living in polluted environments (Evans and Edgerton 2002). Most field studies involved chemical analysis of the metal content of crayfish tissues and provided little information on the pathology of heavy metal exposure (Dickson et al 1979;Finerty et al 1990;King et al 1999;MacFarlane et al 2000;Rowe et al 2001). There are also many laboratory studies that provide data on the toxicity of metals to freshwater crayfish, the concentrations of metals causing mortality and the pathological effects arising from heavy metal exposure (Bagatto and Alikhan 1987;Naqvi and Flagge 1990;Naqvi et al 1990;Naqvi and Howell 1993;Reddy et al 1994;Maranhao et al 1995;Anderson et al 1997a, b;Bollinger et al 1997;Naqvi et al 1998;Anto´n et al 2000).…”

Impact of an introduced Crustacean on the trophic webs of Mediterranean wetlands

et al. 2005

Based on a review and our own data, we present an overview of the ecological impacts on the trophic web of Mediterranean wetlands by an introduced Decapod Crustacean, the red swamp crayfish (Procambarus clarkii). P. clarkii lacks efficient dispersal mechanisms but is very well adapted to the ecological conditions of Mediterranean wetlands (fluctuating hydroperiods with regular intervals of drought). As an opportunistic, omnivorous species, which adapts its ecology and life history characteristics, such as timing and size at reproduction to changing environmental conditions, it became readily established in most of the Mediterranean wetland environments. High reproductive output, short development time and a flexible feeding strategy are responsible for its success as an invader. Like most crayfish, it occupies a keystone position in the trophic web of the invaded system and interacts strongly with various trophic levels. It efficiently grazes on macrophytes and is one of the main factors, besides the impact of flamingos, cattle and introduced fish, of the change of many water bodies from a macrophyte dominated, clear water equilibrium to a phytoplankton driven turbid water balance. Juveniles feed on protein rich animal food with the corresponding impact on the macroinvertebrate community in competition with other crayfish or fish species. At the same time, it serves as a prey for mammals, birds and fish. Due to its predatory and grazing activity, it efficiently canalises energy pathways reducing food web complexity and structure. Feeding also on detritus it opens, especially in marshlands, the detritic food chain to higher trophic levels which results in an increase of crayfish predators. As a vector of diseases, it has a severe impact on the preservation and reintroduction of native crayfish. P. clarkii accumulates heavy metals and other pollutants in its organs and body tissues and transmits them to higher trophic levels. Due to the long history of its presence, the complex interactions it established within the invaded ecosystems and the socio-economic benefits it provides to humans, prevention and control seem the most promising management measures to reduce the negative impact of this crayfish species.
