“…This might be due to the combined e!ect of structural damage (causing a depletion of protein concentration and, to less extent, of lipid concentration) and the in"ltration of haemocytes in the epithelial tissue, as reported by Bubel (1976) and Torreblanca et al (1987).…”

“…The changes observed in protein concentration after lead exposure could be due to the toxic e!ect of a nonspeci"c mechanism that interferes with protein metabolism, as suggested by Torreblanca et al, (1987), or the modi"cation of sulfhydryl groups and other ligands of the cell membranes altering its structure and function (Webb, 1966), rather than to the speci"c inhibition of certain enzymes. Inhibition of protein synthesis by exposure to heavy metals has also reported in crustaceans, but results were not de"nite (Bubel, 1976).…”

“…In addition, the gills form a mucous sheath as a protective response which in turn adsorbs the metals (Anderson, 1978;Anderson and Brower, 1978). Lead and chromium have also been demonstrated to damage the gills as demonstrated by histopathological study (Torreblanca et al, 1987;Anderson et al, in press;Bollinger et al, in press). …”

“…Heavy metals interfere with the respiration and osmoregulation functions of the gills in fish and crustaceans (Baker, 1969;Eisler and Gardner, 1973;Jones, 1975). Lead not only causes a decrease in oxygen uptake by the whole crayfish, but also produces a significant decrease in oxygen consumption by excised gills (Torreblanca et al, 1987). Low concentrations of lead and/or cadmium cause a decrease in activity of oxidative enzymes in the gills (Meyer et al, 1991).…”

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.

“…Similar oxygen consumption rates were measured for Procambarus clarkii (ca. ww 25 g) and these decreased from 260 to 130 lg g crayfish dw -1 h -1 (converted from ll g crayfish ww -1 ) after dissolved lead exposure (Torreblanca et al, 1987). Much higher oxygen consumption rates of approximately 875 lg g crayfish dw -1 h -1 (converted from ml h -1 ) were measured for small (ca.…”

Measuring sub-lethal effects on freshwater crayfish (Paranephrops planifrons) behaviour and physiology: laboratory and in situ exposure to modified zeolite

Various behavioural and physiological tests were applied to determine whether an aluminised modified zeolite clay product (Z2G1), used to cap phosphorus release from lake sediments, had sublethal effects on adult freshwater crayfish (Paranephrops planifrons). In situ exposures of caged crayfish before and after application of modified zeolite to Lake Okaro, Central North Island, New Zealand, at a nominal application concentration of 350 g m -2 , did not impact the survival of freshwater crayfish or produce any significant sub-lethal effects on crayfish mobility or physiology that we could detect. In laboratory sediment tests, crayfish did not show any consistent effect from short-term (10 days) exposure to modified zeolite (at concentrations of 350, 700 or 2,100 g m -2 ) or to alum. When combined, the field and laboratory data provide strong evidence that applications of 350 g m -2 modified zeolite will have no short-term effect on adult crayfish, with a 'margin of safety' for higher application rates. Chronic exposure effects of capping agents and the indirect impacts of lake treatment (e.g. food web responses) are yet to be determined. Quantitative measures of shade-and shelter-seeking behaviour, righting behaviour, and length of escape response, could be improved by the addition of standardised behavioural observations. Physiological measures of ammoniacal-N production and oxygen consumption are less variable than behavioural tests, but comparisons between treatments are best conducted simultaneously. A suite of behavioural and physiological sub-lethal measures using field and laboratory exposures is recommended to provide an integrated assessment of crayfish health.
