Freshwater Fishes of CanadaFisheries Research Board of Canada, 1973 - 966 pagine The Fisheries Research Board is proud to present this volume, a tribute to the cooperation between the government agency that initiated and supported the work and the research organization that carried it out. It is the hope of the authors that this text will perform a useful service by highlighting the lack of information on many aspects of the biology of many Canadian fish species. Particularly glaring is our ignorance of the basic life history of many common species. |
