Trade Paperback. Condizione: 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. Interior text and illustration pages are bright, tight, and white. 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. Inorganic matter and various biota (bacteria, fungi, Protozoa, meiofauna and larger invertebrates) may occur in association with detritus, but they are not detritus per se.…

paperback. Condizione: Good. Our good condition books are generally good for reading but not for gifting or collecting. They could have imperfections such as creasing, fanning, inscriptions, margin notes, yellowing, staining on edge or cover or pages, bumps, scuffs, etc etc (sometimes multiple of these). It's a wide category that encompasses anything that isn't almost-new down to anything that is slightly better than poor.
