Habitat separation of the crab potamon potamios and the crayfish pontastacus leptodactylus in Lake eğirdir, Turkey

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

Sorting grid usage to reduce the catch of undersized narrow-clawed crayfish (Pontastacus leptodactylus Eschscholtz, 1823) in fyke net fisheries

Fisheries Management and Ecology
Abstract Sustainability of natural stocks of crayfish is critical because of their economic and ecological importance. Crayfish (Pontastacus leptodactylus), one of the most important species in Turkish inland fisheries, has been facing serious threats recently.

<i>Procambarus virginalis</i> Lyko, 2017: A new threat to Iberian inland waters. [PDF]

Ecol Evol
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...

The Potential of Defatted Yellow Mealworm (Tenebrio molitor) Meal as an Alternative Protein Source for Juvenile Chinese Mitten Crab (Eriocheir sinensis). [PDF]

Aquac Nutr
This study was aimed to investigate the effects of replacing dietary fish meal (FM) with defatted yellow mealworm (Tenebrio molitor) meal (DYM) on growth performance, intestinal health, serum immune, and antioxidant indexes of juvenile Chinese mitten crab (Eriocheir sinensis).

Diversity and Prevalence of Fungi Associated with Freshwater Crayfish in Three Regions of Lithuania: A First Assessment [PDF]

Microorganisms
Fungi play an important role in freshwater ecosystems, yet their diversity and distribution among crayfish species remain poorly understood. We analyzed the diversity of fungi in four crayfish species (Astacus astacus, Faxonius limosus, Pacifastacus ...

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

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

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 ...

Characterization and phylogenetic analysis of the complete mitochondrial genome of invasive Pontastacus leptodactylus in China

Aquaculture Reports
The spread of invasive crayfish species poses a serious threat to the freshwater ecosystems. However, it is also a chance to enrich the resources for crayfish genetic resource.

A sample model for applying feature selection and machine learning techniques to estimate and manage crayfish populations [PDF]

Scientific Reports
Sustainable fishing and aquaculture production require not only data collection but also its proper application. Another factor influencing the study’s direction is dataset size. Regardless of dataset size, the most critical aspect of data use is feature
