Abstract

The occurrence of algal bloom in a fish pond with Nile Tilapia, Oreochromis niloticus Linnaeus (Cichlidae) was recorded at the Experimental Fish Culture Station in Pindamonhangaba, located at 22º55´S, 45º27´W, in the State of São Paulo, Brazil. During one month (February 2001) at every three days of study the water quality was performed. From results, it was observed that the ammonia, total pigments, water transparency, phosphate and dissolved oxygen showed values out of the recommended limit. The algal bloom was associated to the loads phosphate and nitrogen and the fish mortality to the low oxygen and toxic ammonia. The low oxygen values were associated to the bloom and the organic material in decomposition
