At least 50 tons of cultured tilapia were lost as fish kill hit parts of Taal Lake in Batangas province, a normal phenomenon that occurs during the cold months, according to experts. Mario Balazon, spokesperson of Taal Lake Aquaculture Alliance Inc. (TLAAI), said the fish kill occurred on Saturday night off the villages of Aya, Quiling and Tumaway in Talisay town. He said 25 out of the 750 cages there were affected. The phenomenon was caused by the lake’s “overturn” and a possible sulfur upwelling brought about by the northeast monsoon.
