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.

Beyond Niche Overlap: Axis‐Specific Reorganisation of Environmental Space in Freshwater Crayfish Invasions

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Understanding whether invasive species retain or shift their ecological niches has relied on scalar overlap metrics that quantify the magnitude of niche change but not its structure. Here, we test whether biological invasions involve a reorganisation of the environmental axes along which native and invasive ranges are differentiated, and ...

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

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

The spread of non‐native species

Biological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

ROUNDTABLE SESSION 4A: MANAGEMENT: REINTRODUCTIONS AND RESTOCKING.

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.

First record of the stone crayfish in the Romanian lowlands

Knowledge and Management of Aquatic Ecosystems, 2021
The stone crayfish is a native European freshwater species with significant population declines caused by anthropogenic pressure onto its habitats, climate change and spreading of non-indigenous invasive crayfish and their pathogens (e.g., Aphanomyces ...

Two indigenous European crayfish under threat – how can we retain them in aquatic ecosystems for the future?

Knowledge and Management of Aquatic Ecosystems, 2011
Indigenous crayfish species (ICS) are under threat in Europe; due to competition from invasive non-indigenous crayfish species (NICS) from crayfish plague, which is carried by introduced American crayfish, and habitat degradation.

Predatory decapods for biological control of pest snails: Ecological, behavioural and mechanical aspects

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
A food‐choice experiment illustrating that monosex decapods can serve as efficient biological control agents against parasite‐transmitting snails in aquaculture systems. We presented prawns and crayfish to four pest snail species with varying shell characteristics and quantified their predation preferences and traits. We show that the force required to
