Recirculation aquaculture systems (RAS) are gaining popularity among producers due to high productivity and low ecological impact for the production of aquatic food. Water quality management has always been considered though to be one of the most important aspects of (RAS) systems from both perspectives: ensuring an appropriate environment for fish development and growth and reducing nutrient pollution discharge. In RAS systems, total ammonia nitrogen produced by fish as a result of protein catabolism it is commonly controlled through biofiltration. The biofilters however are the most difficult components to manage once the RAS is in operation. In aquaculture farms collapse of biofilter often occur as a result of bad management and, therefore, a rapid alternative for ammonia control is desirable. The purpose of the current study was to compare the capacity of natural zeolite filtration systems and of trickling biological filter to control total ammonia nitrogen in an experimental aquaculture recirculating system. The results of the experiments indicate natural zeolites as a promising alternative to biofiltration in freshwater intensive fish culture.
