Freshwater crayfish Astacus leptodactylus (Eschscholtz, 1823) accumulates and depurates copper.
Cu accumulation and depuration in various tissues of the crayfish Astacus leptodactylus was investigated. Adult specimens were exposed to 0.5, 2.5 and 5.0 mg Cu/L under static conditions for three weeks. At the end of the 3rd week the specimens were divided into three groups and left in dechlorinated water for either 1, 2 or 3 weeks for depuration. After 7, 14 and 21 days, four crayfish from ea...
متن کاملEffects of zinc oxide nanoparticles and zinc ions on intestine histopathology of freshwater crayfish (Astacus leptodactylus)
The purpose of this study was to evaluate the effects of zinc oxide nanoparticles and ions on intestinal tissue histopathology of freshwater crayfish (Astacus leptodactylus) under laboratory conditions. We evaluated two concentrations of zinc oxide nanoparticles and zinc ions (0.5 µm/l and 1.0 mg/l) with a control group. After 14 days of exposure to the nanoparticles of zinc oxide and zinc ions...
متن کاملTemporal Changes in Concentrations of Some Trace Elements in Muscle Tissue of Crayfish, Astacus leptodactylus (Eschscholtz, 1823), from Keban Dam Lake
Crayfish (Astacus leptodactylus Eschscholtz, 1823) is the native crayfish species in Turkey. It was exported regularly to Western Europe. In this study, bioaccumulation and temporal trends of some trace elements (arsenic: As, cadmium: Cd, copper: Cu, mercury: Hg, lead: Pb, and zinc: Zn) in edible abdomen muscle of crayfish from Keban Dam Lake (Elazığ, Turkey) were investigated for the 2006-2012...
متن کاملPseudodiarrhoea in zebra mussels Dreissena polymorpha (Pallas) exposed to microcystins.
Microcystins are produced by bloom-forming cyanobacteria and pose significant health and ecological problems. In this study we show that zebra mussels respond differently to different strains of Microcystis aeruginosa, and that a highly toxic strain causes zebra mussels to produce large quantities of mucous pseudofaeces, 'pseudodiarrhoea', that are periodically expelled hydraulically through th...
متن کاملSecondary spread of zebra mussels (Dreissena polymorpha) in coupled lake-stream systems
We postulated that dispersal through streams is an important factor in the spread of nonindigenous aquatic species to uninvaded lakes. We tested this hypothesis with zebra mussels (Dreissena polymorpha), whose planktonic larvae are particularly prone to transport through streams. To examine this potential mechanism of spread, we (1) assessed populations of zebra mussels in 2000 and 2003 in coup...
