Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology [PDF]

NeoBiota
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused on the NCE of predator-induced stress from one native

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

First detection of Aphanomyces astaci and its potential responsibility for mass mortalities of Pontastacus (Astacus) leptodactylus in Greek lakes

Journal of Biological Research - Thessaloniki
Aphanomyces astaci is a pathogen categorized among the 100 worst invasive alien species, responsible for the crayfish plague disease. In the past, many disease outbreaks devastated native European crayfish populations.

Standardization of pleopodal egg number in narrow-clawed crayfish ( Pontastacus leptodactylus Eschscholtz, 1823)

Invertebrate Reproduction & Development
In this study, the effects of certain biotic factors (length, presence of lesions) and abiotic factors (month of fishing and fishing area) on pleopodal egg production of Pontastacus leptodactylus (Eschscholtz, 1823) were examined to determine the optimal productivity of spawned female crayfish for aquaculture purposes.

ЕФЕКТИВНІСТЬ КОНТЕЙНЕРНИХ СИСТЕМ З АЕРАЦІЄЮ ДЛЯ ВИРОЩУВАННЯ ВУЗЬКОПАЛОГО РАКА (PONTASTACUS LEPTODACTYLUS)

Bulletin of Sumy National Agrarian University. The series: Livestock
У статті розглядається ефективність вирощування вузькопалого прісноводного рака (Pontastacus leptodactylus) у контейнерній системі з аерацією. Метою дослідження було визначення оптимальних параметрів годівлі та оцінка впливу фізико-хімічних характеристик водного середовища на продуктивність та фізіологічний стан раків у віці від 9 до 12 місяців ...
