Fatma Idris, BFAR director of the Davao regional office, said the death of fishes in the fish cages off coastal Barangay Gwang-Gwang in Mati was likely caused “by the sudden shift in temperature, from the warm waters to the drop in temperature when the low pressure area turned the ocean water colder than the bangus fishes could easily adjust to.”
“That sudden change in ocean water temperature could be the culprit more than anything else,” she said in a radio station interview on Thursday.
The LPA in the Pacific Ocean sent devastating flashfloods over the weekend to most of eastern Mindanao, but caused damage mostly along the east coastal towns of Davao Oriental.
On Wednesday Idris said owners reported wholesale death of bangus in fish cages off the Mati coast, with between 3,000 and 5,000 bangus dying in each fish cage.
The area has about five groups of cages, she said.
Idris said BFAR technicians were sent to take vital parameters of the area, including water samples that might reveal many indicators, including water temperature, chemical composition and physical characteristics of the waters in and around the mariculture park.
“By then, we could also make a clearer approximate of the volume of fish deaths and the damage to the cages,” she added.
Although many cage owners buried the fishes, she warned coastal communities and local markets to refrain from selling contaminated or poisoned fish to prevent food poisoning.
