Summary: | Taal Lake is a 24,356-hectare body of water which is tapped for
aquaculture, fishing, navigation, and tourism spot of Talisay, Tanauan, Batangas.
Taal Lake is also classified under Class C since it serves as fishery water used for
the propagation of fish and other aquatic sources. The study conducted in the said
site focused on its role for aquaculture. This lake serves as the home for many
fishes, especially tilapia, and a primary source of income for most residents near
the area. The water quality and food available for these fishes are very important
factors for them to grow well. Phytoplankton is a group of microscopic plants
commonly known as algae which serve as the foundation, the first link of the
marine food chain and serve as food for aquatic organisms. These organisms are
good indicators of pollution and water quality of the lake. Based on the study
conducted, there are 64 species of phytoplankton found which belongs to 4 phyla,
14 classes, 14 orders and 22 families. The most abundant species found in the dry
season were Melosira islandica, Stauroneis anceps, Stephanodiscus hantzschii,
Melosira granulata and Synedra ulna.. The most abundant species found in the
wet season were Synedra acus, Oscillatoria ornate, Melosira granulata and
Staurastrum cuspidatum.. Some of these species are involved in water pollution in
number of ways causing massive fish kills. The physicochemical parameters such
as pH, temperature, DO, nitrate content, phosphate content and water
transparency obtained in Taal Lake were correlated with the abundance of
phytoplankton species wherein these parameters have a significant effect on the
abundance of phytoplankton species. |
