Geothermal aquaculture
Future supply of proteins for human consumption are more and more dependent on developments of aquaculture, particularly in regions characterized by limited use of meat, milk and derivatives. Particularly interesting is intensive thermal aquaculture, using low cost heat such as the one obtained by industrial effluents and geothermal fluids. The use in aquaculture of geothermal fluids is rapidly expanding, particularly in the Far East, Europe, USA and Comecon Countries. It requires specific techniques, availability of non geothermal fluids, heat exchangers, water treatment, disposal of waste waters. The joint availability of heat and CO/sub 2/, which characterizes many geothermal fluids, may allow the development of food chains, of the types: microalgae (e.g. Chlorella, Spirulina), crustaceans (e.g. Artemia), fish or prawns, the treatment and conservation of products, the production of fodder, proteic concentrates for human consumption, bio fertilizer, etc. Relevant cost reductions could this way be obtained with respect to present marker prices, controlled by vegetal proteins (soya, cereals) and meat; these proteins might become scarce in the future due to population growth and to the saturation of traditional resources.
