Invasive Crayfish: Drivers or Passengers of Degradation in Freshwater Ecosystems?
Environmental DNA, Volume 7, Issue 2, March/April 2025.Environmental DNA metabarcoding provides insights in microbial community responses to an invasive species and nutrient pollution, two prominent freshwater stressors. ABSTRACT Invasive species, such as the freshwater crayfish Procambarus clarkii, reportedly negatively influence the abundance of various aquatic species.

Non-invasive detection of Aphanomyces astaci on individual crayfish
, 2019 Pathogenic oomycete Aphanomyces astaci is transmitted mainly by invasive North American crayfish, and causes the crayfish plague, a disease mostly lethal for native European crayfish. Detecting the pathogen in endangered native crayfish populations before the disease outbreak would provide a starting point in the development of effective control ...

Environmental DNA, Volume 7, Issue 2, March/April 2025.ABSTRACT Viral hemorrhagic septicemia virus (VHSV) is a major pathogen in aquaculture worldwide, causing significant outbreaks through waterborne transmission. This study aimed to evaluate the effectiveness of environmental RNA (eRNA)‐based surveillance for detecting VHSV in aquaculture systems, focusing on the relationship between infection dynamics ...

Freshwater Biology, Volume 70, Issue 2, February 2025.ABSTRACT The ornamental pet trade has emerged as one of the most important pathways for the introduction of non‐native aquatic species. In the last two decades, freshwater crayfish have become a popular ornamental group, with numerous non‐native populations established through this way, including some populations of the North American red swamp ...

Knowledge and Management of Aquatic Ecosystems, 2006 There are only very limited reports about the occurrence of the crayfish plague in Czechia. In recent years, mass mortalities of Astacus spp. with symptoms of possible crayfish plague were noticed in three streams in the country two in Central Bohemia (

Journal of Invertebrate Pathology, 2017 Aphanomyces astaci infection is the cause of crayfish plague in European crayfish. Here the virulence of an A. astaci As strain isolated from apparently healthy stone crayfish (Austropotamobius torrentium) from Slovenia was compared to that of the Psl-Puujärvi A.
