Effects of Prawn Shell Meal Diets on Hemocyte Count, Hemolymph Clotting, and Sperm Quality of the Freshwater Prawn Macrobrachium caementarius

Aquaculture Research, Volume 2026, Issue 1, 2026.
Crustacean shells are composed of chitin, which is bound to protein and minerals, along with other essential nutrients. These components are necessary for growth, immune response, the formation of reproductive structures, and the enhancement of sperm quality.

Dietary Pectin Supplementation as a Potential Strategy to Mitigate the Toxic Effects of Microplastics and Cadmium in Freshwater Crayfish (Astacus leptodactylus)

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study investigated the effects of cadmium (Cd), microplastics (MPs), and pectin (Pec) supplementation on biochemical, oxidative, and immunological parameters in crayfish (Astacus leptodactylus). Four hundred fifty crayfish were acclimatized under controlled laboratory conditions and distributed into 15 experimental groups using a definitive ...

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.

Exploring the Coexposure Effects of Pyrogallol and Microplastic on the Red Swamp Crayfish Procambarus clarkii

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 ...

When Methodological Innovation Changes the Game: A 10‐Year Review of Environmental DNA (eDNA) Applied to Crayfish

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT The use of environmental DNA (eDNA) as a tool for monitoring represents a major innovative advance in environmental science, one that enables the detection of species without the need to observe or capture them. This article assesses the state of play of eDNA research targeting crayfish.
