Abstract

The water column in a fish farm was sampled seven times at three depth layers from 8:00 to 19:00 h to determine short term chances in water quality. NH4 ions were the dominant form of dissolved inorganic Nitrogen (DIN) at the surface layer and peaked at noon, showing an increase by a factor of 7 incomparison to the values recorded at the beginning and the end of the sampling period. PO4 and SiO2 also increased during the day with maximal valuesat the surface. Chla showed little response to this chance in nutrient content except for the deep layer, which showed a consistent increase. Our results support the idea that monitoring of these variables should be properlydesigned to avoid bias due to diel variability.
