Informationen zum Autor Josianne Støttrup is the editor of Live Feeds in Marine Aquaculture, published by Wiley. Lesley McEvoy is the editor of Live Feeds in Marine Aquaculture, published by Wiley. Klappentext As the expansion in world aquaculture continues at a very high rate, so does the need for information on feeding of cultivated fish and shellfish. In the larval and juvenile phases of many species, the use of manufactured feed is not possible. This important book covers in detail the biology and culture of the main live prey and microalgae used as feeds in the aquaculture of major commercial species including shrimps, sea bass, halibut, cod and bivalves. Contents include comprehensive details of the status of marine aquaculture in relation to live prey, and chapters covering the biology, production, harvesting, processing and nutritional value of microalgae and the main prey species: rotifers, Artemia and copepods. The editors have drawn together an impressive international team of contributors, providing a work that is set to become the standard reference and practical guide on the subject for many years to come. Live Feeds in Marine Aquaculture is an essential purchase for anyone involved in marine aquaculture, including fish farmers, researchers, and personnel in feed and equipment companies supplying the aquaculture trade. An extremely valuable tool as a reference and practical manual for students and professionals alike; libraries in all universities and research establishments where biological and aquatic sciences and aquaculture are studied and taught, should have copies available on their shelves. Zusammenfassung This manual provides comprehensive coverage of the biology! culture methods and uses of live prey species in aquaculture. These species ! which includes shrimps! algae and copepods! are cultured and fed to fish mainly in marine culture systems. Inhaltsverzeichnis 1.
