An experimental greenhouse was constructed at the fish pond site of the Federal College of Freshwater Fisheries Technology, Baga using the freestanding design style. Air temperature, water temperature and evaporation readings were observed for two weeks. Temperature records in the green house ranged between 25-27~'C at 6am and 26-32~'C at 6pm while atmospheric temperature was observed between 22-25~'C at 6am and 24-28~'C at 6pm respectively. Evaporation rates were observed to be higher in the water trough placed outside than the one placed inside the greenhouse. Water depth dropped from 39.5cm to 34.5cm (i.e 9cm) and 39.5cm to 30.5cm (5cm) in the trough placed outside and inside the greenhouse respectively. From this experiment, water is connserved as a result of low evaporation rate and higher water temperatures are attainable in the greenhouse which is desirable in the extremely cold harmattan season in the arid zone of Nigeria.Page Range
