More than three fourth (85.41 percent) of this number are non-motorized while the rest are motorized. The highest number of both motorized and non-motorized fishing boats came from barangay Halag of Aguinaldo.
The fishkill has been plaguing the province since May.
Lunag said in a square meter there are three fishes, which thrive explaining the 200 hectares affect immeasurable farms with fingerling and fully-grown fishes.
The provincial agriculturist said technicians are now crafting remedies to the phenomenon with experts adding anti biotics to the feeds given to fish and turning to aeration technology to spur oxygenation in ponds.
There are 1,280 fishpond operators in the province, farmgate prices of Tilapia is pegged at P80 to P85 per kilo with five to six pieces of fish in a kilo.
