The study group of freshwater decapods established within the Italian Association of Freshwater Ichthyologists aims at improving knowledge on the biology of both native and alien freshwater crayfish, shrimps, and crabs which currently inhabit Italian lentic and lotic waters, promoting at the same time the establishment of a network of experts that guarantees an adequate spread of correct useful and usable information, not only for management activities by the local and national competent authorities, but even by non-experts. The group deals with taxonomy, systematic, zoogeography, ecology, ethology, physiology, anatomy, genetics, conservation (of natives) and management (of aliens) of freshwater decapods in Italy. Our main aim is to update the status of freshwater decapods within the national territory, useful for monitoring programs on these species and the habitats where they inhabit. It is necessary to study all the aspects of this order because many species represent an ecological (as a keystone species), fauna (some taxa are interesting peninsular endemisms), biogeographical (the Whole order includes peculiar models of dispersion, migration and vicariance) and evolutionary (there are stimulating case studies of adaptive radiation phenomena linked to a specific ecological value) heritage. Also from an applied perspective, freshwater decapods have a peculiar double aspect linked to the conservation of aquatic environments: on the one side some species can be considered as valuable biological indicators, but on the other side many alien species are reported to be invasive and their management is mandatory, according to the new European and Italian legislations, and should be ecologically, economically and culturally examined to evaluate their effects on environment, human activities and health.

Abstract

The study group of freshwater decapods established within the Italian Association of Freshwater Ichthyologists aims at improving knowledge on the biology of both native and alien freshwater crayfish, shrimps, and crabs which currently inhabit Italian lentic and lotic waters, promoting at the same time the establishment of a network of experts that guarantees an adequate spread of correct useful and usable information, not only for management activities by the local and national competent authorities, but even by non-experts. The group deals with taxonomy, systematic, zoogeography, ecology, ethology, physiology, anatomy, genetics, conservation (of natives) and management (of aliens) of freshwater decapods in Italy. Our main aim is to update the status of freshwater decapods within the national territory, useful for monitoring programs on these species and the habitats where they inhabit. It is necessary to study all the aspects of this order because many species represent an ecological (as a keystone species), fauna (some taxa are interesting peninsular endemisms), biogeographical (the Whole order includes peculiar models of dispersion, migration and vicariance) and evolutionary (there are stimulating case studies of adaptive radiation phenomena linked to a specific ecological value) heritage. Also from an applied perspective, freshwater decapods have a peculiar double aspect linked to the conservation of aquatic environments: on the one side some species can be considered as valuable biological indicators, but on the other side many alien species are reported to be invasive and their management is mandatory, according to the new European and Italian legislations, and should be ecologically, economically and culturally examined to evaluate their effects on environment, human activities and health.
