The objective of the work is to use the composting as thermal energy source in the maintenance of aquatic organisms. The area of Toledo possesses annual medium temperature of the air of 20,5ºC and average in the hottest quarter of 27ºC and in the more cold of 16,5ºC. The used experimental material consisted of boxes of water, pipes of aluminum, hay of grassy, manure of birds and swine, aquarium compressors, hoses and pipes, porous stones, fish lingers and thermometer. The temperatures of the air, the composition and the water without heating were monitored. The medium temperatures obtained were of 20,9 and 31,1ºC, for the air and the composition, respectively. The averages of temperature of the water with heating and without heating were of 22,0ºC and 20,0ºC. The weight difference among the fish lingers was of 24,0 %. It is ended that the composting can be a thermal source of energy in the aquaculture.
