Trade Paperback. Etat : Good. First Edition. 419 Pages Indexed with List of Participants. Laid in is a brochure titled ICALARM Publications. Previous owner's name on front cover front endpaper.

The application of biological principles to aquaculture in the disciplines of nutrition, physiology, reproduction and pathology has allowed for rapid expansion and intensification of production from aquacultural systems. A great deal of this research has been done in the temperate zone and has been focused on carnivorous freshwater and marine fish species. Little effort has been devoted to the controlled use of nutrients from decomposing organic matter, particularly in tropical systems. Some extremely successful culture systems are based in large part on microbial-detrital production, notably pond fertilization with livestock manure. The potential for utilizing such detrital systems to reduce or eliminate the need for costly supplementary feed in pond aquaculture is excellent. Full development of this potential is dependent upon more complete knowledge of the systems and assessment of methods for their manipulation. The term 'detritus', as used here, is defined as nonliving organic matter, usually in a particulate form, but also including dissolved organic matter.
