Phytoplankton community in aquaculture and non-aquaculture sites of Taal Lake, Batangas, Philippines
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2016, Vol 4, Issue 0
Abstract
This study was aimed to assess the phytoplankton communities between the aquaculture and non-aquaculture sites of the Taal Lake in Batangas, Philippines for a sampling period of 10 months from August 2013 to May 2014. Total of 39 phytoplankton genera under Division Chlorophyta, Cyanophyta, Chrysophyta and Pyrrophyta were reported from the study site. Among these, 36 genera were observed from the aquaculture sites while only 30 genera from the non-aquaculture sites. Results of the density revealed that availability of phytoplankton was significantly higher in the aquaculture than the non-aquaculture sampling stations for all major phytoplankton divisions. Highest monthly density was also recorded during the summer months of March to May 2014 and lowest in the month of January 2014 due to sulphur upwelling. The most dominant phytoplankton based on importance value for both sampling sites was Microcystis followed by Merismopedia in aquaculture sites and Oscillatoria in non-aquaculture sites, all under division Cyanophyta, indicating the organic pollution and eutrophication of Taal Lake.
