Freshwater Fishes of Eastern Canada (el. knyga) (skaityta knyga) | knygos.lt

Aprašymas

From the more than one million square miles of the six eastern provinces of Canada 154 species of freshwater fishes have been reported. This edition of Freshwater Fishes of Canada provides the game and commercial fisherman and the naturalist with detailed information regarding these fishes, and assists in the accurate identification of the various species. The species are arranged in order of development: primitive first and the more highly specialized fishes last. Each description includes a picture, a list of other common names, the distinguishing features, size, habitat, life history and habits, food, and additional comments. Technical language has been avoided wherever possible but with no loss of accuracy.
In this second edition the author has employed a system of keys for easier identification of families, and of the individuals in the two largest and most difficult species, the trout and minnow groups.
