Increased efficiency and productivity can be achieved in aquaculture systems which contain several species occupying different levels of the food chain, utilizing waste products from the cultured organisms as well as available food. Two systems are described which use secondary‐treated sewage effluent as a nutrient source to grow unicellular algae and to produce, in the same system, several commercially‐important species such as the oyster (Crassostrea virginica), the winter flounder (Pseudopleuronectes americanus), and the lobster (Homarus americanus). Food for the marketable species grows naturally and abundantly in these systems, eliminating the major recurring cost in commercial aquaculture.
