Crayfish extinctions and crayfish plague in central Ireland
Biological Conservation, 1988Abstract The white-clawed crayfish Austropotamobius pallipes (Lereboullet) has been losing ground in Western Europe but remains widespread in Ireland, whose stocks are well-studied and of European conservation importance. Crayfish fungal plague, fatal to white-clawed crayfish, has affected all other European countries; it was first diagnosed in an ...

Interneurons in the tritocerebrum of the crayfish
Brain Research, 1987In isolated head preparations of the freshwater crayfish Orconectes limosus 268 local and projecting interneurons with branches in the tritocerebrum have been penetrated with glass microelectrodes and characterized for their sensory inputs. Using 3 criteria (sensory modality, site of receptors, response type of interneurons), the interneurons found ...

REPLACEMENT OF RESIDENT CRAYFISHES BY AN EXOTIC CRAYFISH: THE ROLES OF COMPETITION AND PREDATION
Ecological Applications, 1999Exotic species are often a threat to native biodiversity. In northern Wisconsin lakes, the invading crayfish Orconectes rusticus is replacing 0. virilis, the native, and 0. propinquus, a previous invader. We tested the impacts of interspecific competition for food and of nonconsumptive effects of predation by largemouth bass, Micropterus salmoides, on ...

Crayfish have been in demand as desirable food items around the globe for centuries, and entrepreneurs have capitalized on this demand by developing and applying aquaculture principals for the intentional culture of this freshwater crustacean. The current state of the art has advanced within the last half century and is centered on a handful of species,
