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 کاملEffects of enriched artemia on growth and survival of juvenile freshwater crayfish (Astacus leptodactylus Esch. 1823)
The experiment was conducted to investigate the effects of artemia enriched with lipid emulsions containing highly unsaturated fatty acids on growth and survival of juvenile freshwater crayfish Astacus leptodactylus. Juvenile crayfish were fed artemia enriched with commercial emulsions (red pepper and olio ω3) and un-enriched artemia (control). The highest eicosapentaenoic acid (EPA) level was ...

متن کاملTissue distribution and correlation profiles of heavy-metal accumulation in the freshwater crayfish Astacus leptodactylus.
The present work details the analysis of heavy-metal and metalloid concentrations in exoskeleton, gill, hepatopancreas, and abdominal muscle tissues of 60 crayfish (Astacus leptodactylus) specimens collected from Lake Hirfanlı, a dam lake located in Kırşehir (Turkey) with a low metal-contamination profile. Concentrations of 11 metals (aluminum [Al], chromium [Cd], manganese [Mn], cobalt [Co], n...
