A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, Volume 42, Issue 8, Page 1691-1704, October 2026.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Status of the white-clawed crayfish, Austropotamobius pallipes (Lereboullet, 1858), in Spain : distribution and legislation

Knowledge and Management of Aquatic Ecosystems, 2000
The white-clawed crayfish, Austropotamobius pallipes, is the only native species of freshwater crayfish in Spain. This species sustained a first-magnitude inland fishery up to the end of 1970's, when the crayfish plague struck the Spanish waters.

Native and Invasive Crayfish Species Impact on the Development of Fire Salamander Larvae: A Pilot Field Study From Northern Italy

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT In northern Italy, the ongoing spread of non‐native red‐swamp crayfish Procambarus clarkii keeps indirectly decimating native populations of white‐clawed crayfish Austropotamobius pallipes complex and is now also threatening local amphibians adapted to slow‐flowing, hilly streams at the borders of its distribution.

The crayfish plague fungus

, 2010
Since 1978 there has been a series of outbreaks of crayfish plague fungus, Aphanomyces astaci in Spain. As a result, most populations of the native freshwater crayfish species, Austropotamobius pallipes , have been devastated by this disease. This paper

Sea Urchin Removal as a Tool, Not a Solution: Practical Lessons for Kelp Restoration in Aotearoa New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The increasing awareness of the extent of urchin barrens and impacts of sea urchin overgrazing on rocky reefs in Aotearoa New Zealand has led to a rapid increase in the use of sea urchin removal as a tool for kelp forest restoration. Here, we review these restoration projects, focusing on three case studies, with the aim to provide context on what ...

LACK OF SPECIFICITY OF THE MOLECULAR DIAGNOSTIC METHOD FOR IDENTIFICATION OF APHANOMYCES ASTACI

Knowledge and Management of Aquatic Ecosystems, 2007
A recent PCR-test developed for identification of Aphanomyces astaci, the organism responsible for crayfish plague, provided false positives for Aphanomyces frigidophilus, Aphanomyces repetans, and some Saprolegnia spp. Real-time PCR showed that with the

Prevalence of the novel amphibian pathogen Batrachochytrium salamandrivorans in Europe and its relationship to host richness and density

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Policy implications. These results suggest that conserving salamander species could reduce Bsal transmission and Bsal‐induced salamander population declines. Given that Bsal is a generalist pathogen that will be challenging to eliminate, conserving amphibian diversity should help to reduce Bsal prevalence and loads and thus protect highly susceptible ...

Impacts of signal crayfish on stream fishes [PDF]

, 2013
Invasive species cause biodiversity and economic loss globally. Invasive crayfish have a wide range of effects as a result of their high densities and biomass, feeding at multiple trophic levels, aggressive competition for shelter and ecosystem ...

Knowledge and Management of Aquatic Ecosystems, 2002
The present paper summarizes the outcome of a roundtable discussion on reintroductions or restocking as a management strategy for native European crayfish, which took place during the European Crayfish conference in Poitiers, France in September 2001.
