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 ...

Feeding Habits of Narrow-Clawed Crayfish Pontastacus leptodactylus: Implications for Stock Enhancement and Aquaculture

Animals
The narrow-clawed crayfish (Pontastacus leptodactylus), a non-native species accidentally introduced into China’s Irtysh River Basin, has formed a wild population with aquaculture potential, but its natural diet and protein utilization remain poorly ...

First report and molecular characterization of Epistylis sp. infestation in the narrow-clawed crayfish (Pontastacus leptodactylus) from Xinjiang, China

Aquaculture Reports
Introduction: The narrow-clawed crayfish (Pontastacus leptodactylus) is an emerging aquaculture species in Xinjiang, China. Here, we report the first recorded outbreak of a severe epibiotic infestation caused by the sessile ciliate Epistylis sp.

Transcriptomic Analysis of Narrow-Clawed Crayfish (Pontastacus leptodactylus) in Response to High-Temperature Stress [PDF]

Progress in Fishery Sciences
The scientific nomenclature of the Irtysh crayfish is “narrow-clawed crayfish” (Pontastacus leptodactylus). The species under consideration is indigenous to Europe and has a wide distribution. A taxonomic classification of the species inhabiting lakes in

Mapping the Publications on an Economically Important Freshwater Crayfish, Pontastacus leptodactylus, Based on Web of Science

Acta zoologica bulgarica
We provide a comprehensive survey on the bibliometric analysis of scientific publications on Pontastacus leptodactylus published in Web of Science (WoS). We found, based on 822 WoS publications, that countries such as Türkiye, France and Iran were among the leading contributors in this field during 1965-2023. Türkiye led with 216 publications, followed

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,
