A review of ecological interactions between crayfish and fish, indigenous and introduced (2011, unknown): “However, decapods (crayfish and crabs), as the largest active predatory or broadly omnivorous invertebrates in many freshwater systems, are also capable of dominating secondary production and biomass (Geiger et al., 2005; Gherardi, 2007; Reynolds and Souty-Grosset, 2011).”
A review of the ever increasing threat to European crayfish from non-indigenous crayfish species (2009, background): “The greatest threat to crayfish biodiversity is from non-indigenous crayfish introduced for harvesting for food or unintentionally as unused bait or unwanted aquarium pets (Holdich, 1999; Taugbøl and Skurdal, 1999; Lodge et al., 2000; Gherardi, 2007; Taylor et al., 2007).”
Review and new records of non-indigenous freshwater invertebrates in the Ebro River basin (Northeast Spain) (2010, unknown): “Yabbies show strongly aggressive, competitive and predatory behaviour towards other animals, and burrowing by yabby can be a problem by the damage caused to crops, lawns, golf courses, dams walls, dykes, irrigation canals, rivers and lakes banks (Gherardi 2007b; Lynas et al. 2007).”
Crayfish invading Europe: the case study of Procambarus clarkii (2006, background): “Though no quantitative study has been yet made, the appearance of high densities of P. clarkii has been considered responsible for the increase in the number of avian species, like the Ardaeidae Botarus stellaris, Egretta garzetta, and Ardea purpurea, together with cormorants, in some European areas”
Managing invasive crayfish: is there a hope? (2011, background): “They also constitute the main prey of several species, including otters, fishes, and birds (Gherardi 2007a).”
Biological control of invasive populations of crayfish: the European eel (Anguilla anguilla) as a predator of Procambarus clarkii (2010, background): “with native crayfish species, to reduce the biomass and richness of hydrophytes, snails, and other components of the food web, and overall to affect ecosystem services (e.g. Lodge et al. 1994; Nyström et al. 1996; Gherardi and Acquistapace 2007; Gherardi 2007).”
Red swamp crayfish: biology, ecology and invasion - an overview (2015, background): “…range of environmental conditions, elevated adaptive capacity, high growth rate and flexible feeding strategy (Hobbs et al., 1989; Gutiérrez-Yurrita et al., 1999; Alcorlo et al., 2004; Souty-Grosset et al., 2006; Gherardi, 2007), features that favour its establishment in new available habitats.”
Invasive alien Crustacea: dispersal, establishment, impact and control (2011, background): “…Orconectes limosus (Rafinesque), and the signal crayfish, Pacifastacus leniusculus (Dana), can reach densities of 70 and 30 m-2 respectively in the invaded European countries, whereas population density of the native noble crayfish Astacus astacus (L.) is 14 m-2 on average (Gherardi 2007).”
Alien Invertebrates and Fish in European Inland Waters (2009, background): “... (2) hybridisation with native species with the consequent reduction of genetic diversity, e.g., Carassius auratus and C. carpio (Hanfling et al. 2005); (3) disruption of the pristine interactions between species and of the existing food web links, e.g., rainbow trout (O. mykiss) (Nystrom et al. ”
The top 27 animal alien species introduced into Europe for aquaculture and related activities (2010, background): “…(e.g. crayfish plague dissemination, habitat modifications, predation, competition, bioaccumulation of heavy metals and other water pollutants etc) (Gherardi, 2006, 2007b; Tricarico et al., 2008), while other species, such as C. auratus and C. peled, may cause one type of impact only…”
Alien species in fresh waters: ecological effects, interactions with other stressors, and prospects for the future (2010, background): “Alien crayfish species often reach high densities (>1 m )2 , Bobeldyk & Lamberti, 2008), and so may have strong direct and indirect ecological impacts on several parts of the food web (Hobbs et al., 1989; Lodge et al., 2000; Gherardi, 2007b).”
Animal xenodiversity in Italian inland waters: distribution, modes of arrival, and pathways (2008, background): “These and other examples (cfr. Leppäkoski et al. 2002a; Gherardi 2007b) confirm that, compared to terrestrial systems, inland waters are highly vulnerable to either inadvertent or deliberate introductions of species and to their subsequent spread.”
