摘要: Abstract A comparison of juvenile growth performance amongst families the freshwater crayfish, C. destructor was carried out under laboratory conditions. Three diets, consisting two pellet diets (15% and 30% protein) zooplankton, were fed to crayfish which obtained from three selected randomly a genetically heterogeneous stock. Juvenile stocked at 1 1−1 in 12 ± tanks did not differ weight broods commencement 35 day trial. Growth survival found with respect diet, zooplankton giving higher greater survival. Growth, but survival, differed by phenotype degree difference being dependent, least part, upon diet. Diet also have pronounced effect on variability size within animals showing substantially lower levels compared equivalent size.
