Limnologica, 2019 Abstract Freshwater decapods rarely co-occur. The crab Potamon potamios and the narrow-clawed crayfish Pontastacus leptodactylus complex usually do not share the same pond even if they live in sympatry. An exception, however, is Lake Egirdir (Turkey), where both species are present. The aim of our study was to analyze the distribution patterns of the

Water, 2023 The growing demand for chitin and chitosan makes it necessary to look for new sources of these polymers and to develop more environmentally friendly methods for their isolation. The subjects of the current study were chitin and chitosan extracted from shells of two crayfish species: P. leptodactylus and F. limosus.

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia
Environmental DNA, Volume 7, Issue 3, May–June 2025.Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.

Aquaculture Research, Volume 2025, Issue 1, 2025.Investigating the impact of two or more toxic chemicals on aquatic organisms is one of the main objectives of toxicological research. Microplastics (MPs) are identified as a carrier or vector for other pollutants. Therefore, the current study investigated the effects of both pyrogallol (PG) and MPs, individually and in combination, on freshwater ...

Study on the Artificial Incubation of Procambarus clarkii Embryos
Aquaculture Research, Volume 2025, Issue 1, 2025.The Procambarus clarkii industry currently faces four major challenges: genetic degradation, disease, unstable prices, and limited breeding methods and modes. Studies on the artificial incubation of P. clarkii embryos can help solve these problems. The purpose of this study was to screen for parameters (disinfectants, embryo stripping stage, embryo ...
