Laguna de Bay is the largest freshwater body in the Philippines with multiple-use. The primary use of the lake is to serve as the future domestic water supply at Metro Manila. The biota of the lake consists of 25 species of fish, 24 species of zooplankton, two species of shrimps, 6 species of mollusks, 42 species of aquatic macrophytes and 154 species of algae. A total of 60 mesophilic anaerobic and facultative anaereobic bacteria and 453 bacterial strains belonging to 22 genera have been identified. A review of 12 papers dealing with biological studies on Laguna de Bay in relation to aquatic pollution is presented. Studies on the impact of heavy metal, pesticide and thermal pollution on the biota of the lake have been sporadic and cursory. There is need for a more comprehensive and systematic monitoring of the lake's pollutants to provide time-series for pollution abatement
