Aquaculture refers to raising fish and shellfish to sell as food and for other uses, such as ornamental and bait fish. Aquacultural engineers concentrate on increasing production while decreasing costs and environmental impacts.

They seek ways to reduce pollution from aquaculture production systems, reduce excess water use, and improve ponds and other fish-rearing systems. They also work with aquatic harvesting, sorting, and processing systems. Agricultural and biological engineers who specialize in water quality, biotechnology, power and machinery, natural resources, food processing, environment, and sanitation are well-suited for careers in this expanding field. As natural fish supplies decline around the world, aquaculture is an area that will continue to grow.
