The use of an industrial waste water treatment facility is examined for cultivation of rainbow trout, striped bass, and the production of aquatic crustaceans to be utilized as food for Maine lobster and fish rations. Six month survival and growth of caged rainbow trout, without supplemental feeding, was similar to values obtained at a local trout farm. The five day old striped bass larvae experienced 100 percent mortality while a three month test of juvenile Maine lobster on rations of water fleas resulted in 85 percent survival. The trout contained detectable amounts of mercury and chlorinated hydrocarbon residue with lower levels of these substances being found in the water of the cultivation pond.
