Traditionally, Recirculating Aquaculture Systems (RAS) were developed to grow freshwater species and produce marine juveniles. However, RAS technology has become increasingly used for the on-growing of a wide variety of fish (including marine species) and shellfish. The ability of RAS to maintain and operate at a constant yet adjustable quality of rearing water (temperature and salinity) means more intensive and reliable production is possible while saving substantial energy. In fact, the annual production capacity of some industrial systems can now amount to thousands of tons.
As part of this course, leading experts in RAS technology will present on the principles and concepts in RAS and discuss the operation of conventional and ‘ecosystem approach’ based RAS. Participants will gain an understanding of the principles of recirculation technology, the types of RAS and their specificities, capabilities and limitations, the advantages and necessary conditions for the optimal use / operation of RAS and the ongoing research which can increase the efficiency and nutrient use of RAS.
