DAGUPAN CITY -- The fish in Pangasinan continue to reel under the impact of climate change on account of the prolonged weather, the Bureau of Fisheries and Aquatic Resources (BFAR) said.
Dr. Westly Rosario, chief of the BFAR's National Integrated Fisheries and Development Center (NIFTDC), confirmed that because of the apparently extended cold weather, fish that housewives are buying from the market are thinner than the ones they are buying during warmer months.
Affected during the cold weather are fishes grown in fishponds, pens and cages not only in Dagupan but also in Pangasinan.
During cold weather, the fishes have the tendency to eat lesser during the cold months, thus do not grow as fast as they do during warmer days, though this is just normal, Rosario explained.
"You know, warm-blooded fish not only do not eat much during the season, but also the females often delay their spawning," he added.
He said the spawning season for milkfish usually comes during the month of March and if it will come a little later, there may be lesser fries to be produced to supply the requirements of fish farmers.
He said in cold countries, salmons which are cold-blooded fish get sick and even die when the weather gets warmer as their body metabolism cannot tolerate warm weather. (PNA)
