Non-technical book about fish. No, not tropical fish in aquariums, but fish in their natural habitat, the waters of Europe, Australia, Africa and Central America. Might put in same category as Ditmar's books on snakes, -- natural history plus personal experience; but it is not in the same category on the basis of style, as this book is rather amateurishly done, though full of interesting facts. Might appeal to sportsmen interested in the background of their hobby. Limited sale.
