Cloth. Condizione: Very Good. No Jacket. 2nd Printing. Hardback. Slight marks to edge. Slight foxing to end inside covers. Blue cloth with green and blue lettering. Our purpose in the book is to give and overview of present, and to some extent past, practices of food aquaculture the world over, within our language and subject to the following constraints. We do not wish to speculate excessively about what might be done if certain incipient technologies and scientific hunches were advanced and perfected. We can, of course, only report what is available in the literature and what workers in the field are willing to tell us. It must be understood that some aquaculture operations are highly competitive, purely profit-oriented ventures and that even scientists in them consider some facets of what they do their secrets, which are not to be published or otherwise devulged. We have restricted ourselves to food species and to some mention of their foods, respectively. For reasons of space and unity we have omitted in our treatment ornamental or industrial living aquatic resources, such as pearls or aquarium fishes or marine colloids from red and brown algae. Illustrated. 868 pp. (We carry a wide selection of titles in The Arts, Theology, History, Politics, Social and Physical Sciences. academic and scholarly books and Modern First Editions ,and all types of Academic Literature.).
