The research was developed so that the red tilapia (Oreochromis sp), fish species that more taken place in Colombia can be exploited in regions where the good conditions for its normal development are not the appropriate ones as in the high regions with temperatures below the 24 °C, applying methodologies related with the use of the solar energy. The evaluated methodologies were: air conditioning by means of solar collectors, air conditioning by means of thermal blanket, air conditioning by means of thermal hoses and air conditioning by means of electric resistances. Factors like functionality, maintenance, organizational and space limitations, and costs were analized.
