Aside from the South China Sea, Taal Lake also provides a source of freshwater fishes to the country. The lake is home to Sardinella tawilis or simply tawilis, a species of freshwater sardine that is endemic to the lake. Taal Lake also provides farmed Chanos chanos or bangus. There is also a good volume of Oreochromis niloticus niloticus and Oreochromis aureus, both locally called tilapia. It is ecologically important to note that neither bangus nor tilapia are native to the lake. Thus they are considered an invasive species to the lake.
