Aquacultural engineering is a multidisciplinary field of engineering that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. Common aquaculture systems requiring optimization and engineering include sea cages, ponds, and recirculating systems. The design and management of these systems is based on their production goals and the economics of the farming operation.
Aquaculture technology is varied with design and development requiring knowledge of mechanical, biological and environmental systems along with material engineering and instrumentation. Furthermore, engineering techniques often involve solutions borrowed from wastewater treatment, fisheries, and traditional agriculture. Aquacultural engineering has played a role in the expansion of the aquaculture industry, which now accounts for half of all seafood products consumed in the world. To identify effective solutions the discipline is combined with both fish physiology and business economics knowledge.
