Fisheries production in the Philippines could continue to improve in the third quarter, with the weather favoring the growth of plankton that fish depend on for food, a former fisheries official said.

“That is the trend that I am seeing with El Niño, (assuming no other) extreme weather disturbance,” according to Asis G. Perez, former director of the Bureau of Fisheries and Aquatic Resources and co-convenor of advocacy group Tugon Kabuhayan.

Mr. Perez said fish eat more in warm weather, allowing them to grow bigger. Warm weather also encourages plankton growth, on which the fish feed.

“Since primary production happens with sunlight, the production of the food for fish will be higher this time as El Niño is entering,” he told BusinessWorld by phone.

The government weather service, known as PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration), has forecast the possibility of an El Niño episode beginning in June, running until the first quarter of 2024.

Fisheries production in the first quarter rose 2% to 991.14 thousand metric tons, led by the marine municipal fisheries and aquaculture subsectors.

From the three months to June, Mr. Perez said fishermen reported a good harvest as favorable weather allowed them to fish, while supply-chain disruptions are clearing up for processed animal protein (PAP), a material used in fish feed.

The Philippine Statistics Authority is set to release agricultural output data for the second quarter on Aug. 9.
