Aquaculture Engineering & Waste Management

Aquaculture engineering is well known of agricultural engineering that studies cultured aquatic species and the production systems used in their culture. Study, research and development in this area ranges from low intensity man-made pond systems to highly intensive recirculation systems involving natural lakes. Aquaculture Waste management is One of the concerns with inshore aquaculture is that discarded nutrients and feces can settle below the farm on the seafloor and damage the benthic ecosystem. According to its proponents, the wastes from aquaculture that has been moved offshore tend to be swept away from the site and diluted. Moving aquaculture offshore also provides more space where aquaculture production can expand to meet the increasing demands for fish.

Aquaculture techniques have been developed in recent years for the production of fish and other aquatic products in closed recirculation systems. To make this work, aquaculturists have needed to develop knowledge of the biological processes operating, such as how bacteria can be used to neutralise and re-cycle the nitrogenous waste products produced by growing fish and how to engineer the systems to meet the biological requirements. Knowledge of bio-engineering from the waste treatment and water treatment industries has made contributions to the development of closed aquaculture systems and there is probably more that could be usefully transferred from the sewage treatment sector to help solve problems in fish rearing.
