Abstract

This study was performed to evaluate the effect of tank position on the water temperature of fish culture tanks in aquaculture facilities inside a greenhouse. The temperature was measured in four 20- m3 capacity tanks. Three points were measured for each tank: point A, the water in the fish culture tanks; point B, the environment outside of the tanks and point C, a point 0.3 m below the soil level. The measurements were recorded in periods of five minutes with data loggers. Significant differences in water temperature were found among the fish culture tanks with a grade of significance of 0.05 and environmental and soil temperature proved to exert an important influence on the water of the fish culture tanks. The mean value of the r-Pearson correlation found is 0.87.

Key words: Aquaculture, temperature, greenhouse, culture tanks, thermal behavior.
