Procambarus acutus

After 48 h in acidified water (pH 4.8 and 3.5), crayfish Orconectes virilis and Procambarus acutus) showed reduced behavioral responses, i.e. antennule and feeding movements, to food odors (Tierney and Atema 1986). Several earlier studies on crustaceans focused on the effects of drilling fluids and crude oil on the chemoreception and behavior in connection with foraging and food search (e.g. Derby and Atema 1981). Blue crabs (Callinectes sapidus) and Dungeness crabs (Cancer magister) detected low concentrations of the hydrocarbon naphthalene (Pearson and Olla 1980). 

Two commercially important species of Louisiana crayfish, Procambarus clarkii and P. acutus, from the Atchafalaya River Basin, from open ponds, and from the sediment and water of these environments, were sampled three times during two consecutive fishing (production) seasons [19]. The abdominal muscle and hepatopancreatic tissue were analyzed separately. Lead, Hg, and Cd, if present, were in concentrations below the limit of detection (LoD). The heptato-pancreatic tissue contained (in p,gkg 1) Ba<8, Cu 11-15, and Fe < 640. Abdominal muscle samples had <3 p,gkg 1 of most metals. Locations with the highest levels of metal residues in sediment were not necessarily locations where crayfish had the highest levels in their tissues.
