Ontogeny of osmoregulation in the crayfish Astacus leptodactylus.
Osmoregulation was studied during the postembryonic development of Astacus leptodactylus Eschscholtz 1823 in juvenile stages 1-8 and in adults.

At all stages, it was longer than in comparable stages of marine ...
متن کاملFreshwater crayfish Astacus leptodactylus (Eschscholtz, 1823) accumulates and depurates copper.

15 صفحه اولTissue 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...
