The Department of Environment and Natural Resources (DENR-Calabarzon) has given the assurance that tilapia fish in markets are still safe to eat amidst a massive fish kill that hit Taal Lake Monday. “We are calling on the public to still patronize the remaining stocks. This is not even 25 percent of one town” DENR-Calabarzon, Regional Executive Director Maria Paz Luna said. The Bureau of Fish and Aquatic Resources (BFAR) issued warnings on Sunday, March 26, that the dissolved oxygen, which should be between 5 to 6 parts per million (ppm) that would allow fish to breathe, was at a dangerously low level of 2.8 ppm. Thus, fish cage owners were advised to move their cages or harvest early.
