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.

Real-Time PCR Assays for Rapid Identification of Common Aphanomyces astaci Genotypes

Frontiers in Ecology and Evolution, 2021
The oomycete Aphanomyces astaci is the etiologic agent of crayfish plague, a disease that has seriously impacted the populations of European native crayfish species.

Comparative analysis of freshwater crayfish growth in different types of water bodies in Ukraine: current trends and variability factors

Ribogospodarsʹka Nauka Ukraïni
Purpose. To conduct a comparative analysis of the growth of freshwater crayfish in different types of water bodies in Ukraine (reservoirs, bays, estuaries) and identify key factors that determine the spatiotemporal variability of their sizes and weights.

Multi-method distribution modelling of an invasive crayfish (Pontastacus leptodactylus) at Eurasian scale

Hydrobiologia
Abstract Globally, human activities profoundly influence biodiversity, frequently favouring biological invasions. Crayfish, prominent invaders on multiple continents, pose significant varied threats. Using species distribution models (SDMs), this study explores the current and future potential distribution of Pontastacus leptodactylus, a ...

Effect of feed and holding conditions on survival and growth of juvenile crayfish Pontastacus leptodactylus and Faxonius limosus

Fisheries & Aquatic Life
In the European natural environment attempts are undertaken to replace invasive crayfish species with native ones. For this purpose, aquaculture of crayfish is required, but their behaviour and the lack of balanced feeds impede further development.

Pathogen diversity of the non-native narrow-clawed crayfish (Pontastacus leptodactylus) in a UK water body

Journal of Invertebrate Pathology
Biological invasions are intrinsically linked to introducing associated symbiotic organisms, some of which can be parasitic or pathogenic. The pathogenic risk of an 'invasive parasite' (aka. exotic pathogen) stems from its potential to infect native hosts and induce behavioural change or mortality, with the pathogen potentially presenting a greater ...

The features of narrow-clawed crayfish (Pontastacus leptodactylus Eschscholtz, 1823) population development in Lake Sevan during 1996–2018

Трансформация экосистем, 2019
The narrow-clawed crayfish, an invasive hydrobiont of Lake Sevan appeared in the lake due to accidental introduction having occupied almost the entire territory of Lake Sevan, finding favorable conditions for its existence.

Are conventional methods sufficient to calculate growth parameters of Pontastacus leptodactylus (Eschscholtz, 1823)? A case study of artificial intelligence from Keban Dam Lake

Oceanological and Hydrobiological Studies
In this study, the length–weight relationships of Pontastacus leptodactylus, a freshwater crayfish species found in the Keban Dam Lake, were assessed using both conventional methods and artificial intelligence techniques. Throughout the research process,

Rapid assessment of population dynamics and monitoring methods for invasive narrow clawed crayfish Pontastacus leptodactylus in a freshwater reservoir

Knowledge and Management of Aquatic Ecosystems
Narrow-clawed crayfish (Pontastacus leptodactylus) are a data deficient invasive non-native species in the UK. Boshaw Whams (West Yorkshire, UK) contains the only known population of narrow-clawed crayfish in Yorkshire.
