Orconectes limosus (Raf.) andAstacus astacus L. (Crustacea, Decapoda) in The Netherlands

GEELEN (Laboratory of Aquatic Ecology, Catholic University, Nijmegen, The Netherlands) INTRODUCTION Up to the end of 1972 Astacus astacus was the only known crayfish in the Netherlands. HOLTHUIS (1950) mentioned in the"Fauna van Neder- land" 38 localities for the period |660-1947 from the southern and eastern part of the Netherlands. In 1972 a large population of another crayfish, Orconectes limos~s (Raf.) = Cambarus uffinis (Say), was found in the Julianakanaal (pro- vince of Limburg) (GEELEN and OOMEN, 1973).
