Aquaculture involves the raising of freshwater or marine organisms in a controlled environment to enhance production rates. The principal species that are typically raised in geothermal waters are catfish, tilapia, bass, trout, sturgeon, giant fresh water prawns, and tropical fish. The application temperature in fish farming depends on the species involved. Typically, catfish grow in 4 to 6 months at 64 to 75F, trout in 4 to 6 months at 55 to 64F and prawns in 6 to 9 months at 80 to 86F. The benefit of a controlled rearing temperature in aquaculture operations can increase growth rates by 50 to 100% and thus increase the number of harvest per year. Water quality and disease control are very important in fish farming
