Fish kill

On January 5, 2008, the Bureau of Fisheries and Aquatic Resources announced that a fish kill at Taal Lake (January 2 to 4) caused the 50 metric tons or ₱ 3.25-million (US$1=₱41) loss of cultured tilapia in the villages of Leviste and Balakilong in Laurel and in Barangay Aya and Barangay Quiling inTalisay. 6,000 maliputo fishes (₱ 230,000) also died at Quiling. Toxic sulfur and high level of hydrogen sulfide in Ambulong while low dissolved oxygen caused the deaths. On May 30, 2011, the Bureau of Fisheries and Aquatic Resources announced a fish kill of 750 metric tons. According to the scientists, the onset of the rainy season brought a sudden drop on the water temperature, which lowered the oxygen levels on the lake. www.wikipedia.org

Its most popular endemic species is the overharvested Sardinella tawilis, a freshwater sardine. The two other endemic fish species in Taal Lake are the gobies Gnatholepis volcanus and Rhinogobius flavoventris. www.wikipedia.org

Leviste added that this will be the last batch of illegal fish cages that they will be dismantling to limit fish cages in the Taal Lake to 6,000.
