REDUCING THE THREAT TO CONTROL INVASIVE SIGNAL CRAYFISH REDUCING: THE POTENTIAL USE OF PHEROMONES

Knowledge and Management of Aquatic Ecosystems, 2003
The need for an effective method of controlling invasive species of crayfish is of utmost importance given the plight of Europe’s native crayfish species. Many techniques have been applied to the growing problem with little success.

Drivers of the range expansion of the European catfish (Silurus glanis) within its native distribution

Journal of Fish Biology, Volume 107, Issue 3, Page 1030-1044, September 2025.
Abstract The European catfish Silurus glanis L. continues to spread as an invasive species in Europe. Meanwhile, increasing abundance and range expansions are also suspected within its native distribution. The objective of this study was to characterize the feeding, growth and abundance of S.

Synergies Between Anthropogenic Litter and Biopollution in SW Bay of Biscay Rivers Discovered Through Citizen Science: Implications for Conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.
ABSTRACT Anthropogenic litter and other pollutants are known to contribute to the introduction and settlement of invasive alien species (IAS) in marine settings; however, the relationship between biopollutant IAS and litter in rivers is much less studied.
