Abstract

An extruded, water-stable diet was fed to selected freshwater crawfishes to observe response and growth. In one study, individual juvenile Procambarus clarkii (Girard) increased an average of 5.1 mm in total length and gained an average o f 1.65 g per molt when fed adlibitum. In a second study, juvenile P. clarkii stocked at densities of 1 mm of animal per 500 mm2 and 125 mm2 and fed 3% of initial estimated body weight increased 5.9 mm (97% survival ) and 3.7 mm (69% survival) in total length, respectively, during a two-week period. In a third study, a total of 17 species of crawfish, including representatives of the genera Cambarellus, Cambarus, Fallicambarus, Faxonella, Orconectes, Pacifastacus, and Procambarus, were maintained in our laboratories for periods of from one month to a year on the extruded diet exclusively. Composition and proximate analysis of the crawfish diet are noted.
