| Summary: | A study involving phytoplankton composition and primary productivity of Canacao Bay located in Fort San Felipe, Cavite City was done from June to December 1995. Only 7 species of phytoplankton were identified namely: Ceratium macroceros (Ehrenberg) Cleve and Peridinium oceanicum Vanhoffen of Family Cistharistaceae Chaetoceros decipiens Cleve and C. siamensis Ostenfeld of Family Chaetoceraceae Coscinodiscus asteromorphalus Ehrenberg, C. lineatus Ehrenberg, and C. oculus iridis Ehrenberg of Family Coscinodiscaceae.Temperature was found to range from 25.8 percent to 32 centigrade pH from 8.3 to 8.4 transparency from 3.020 to 3.048 meters dissolved oxygen from 5.1 to 6.0 mg/L hardness from 0.72 to 0.88 mg/L total solids from 0.808 to 1.180 mg/L nitrates from 0.124 to 0.295 mg/L orthophosphates from 0.151 to 0.375 mg/L and silicates from 1.743 to 3.850 mg/L.The highest gross production was 24.8 mgC/m3/h during the month of September, the highest net production was 13.05 mgC/m3/h during the same month and the highest net respiration was 15.66 mgC/m/h during the month of October.Nitrates, silicates, and orthophosphates were found to be correlated to gross production, net production and net respiration using correlation matrix in microstat with all having positive correlation values. The r-value of significance was 0.75315 using 0.05 level of significance. |
