3.0 RESULTS AND DISCUSSION 

The composition of phytoplankton species in Balanga dam were summarized in Table 1. The result of the study shows that a total of 21 phytoplankton species were identified from the sampling area belonging to about seven different taxa. Chlorophyceae was recorded as taxa with highest species score of about 28.6% of the overall taxa. Baccillariophyceae and Cyanophyceae have a species composition of about 19% species, whereas Desmidiaceae and Chrysophyceae have species of about 14.3 and 9.5% respectively. The taxa having the least species composition were Euglenophyceae and Rhaphidiophyceae with a record of 4.8% (Table 1). In Balanga dam, a total of 426 phytoplankton species were quantified and identified and their respective distribution are summarized in Table 2. As earlier stated, the three sampling stations harbour different types of phytoplankton species. Based on species occurrence, phytoplanktons identified in Side A are Synedra spp (50), Oscillatoria spp (56), Protococcus sp (9), Clostridium spp (10), Botryococcus spp (4), Spirogyra spp (30) and Protococcus spp (9).
