BFAR experiment yields bigger bangus

DAGUPAN CITY,
Pangasinan – Another breakthrough in milkfish production was made
here when an experiment by the Bureau of Fisheries and Aquatic Resources (BFAR)
yielded bangus weighing 500 grams each.
BFAR said the experiment was done in a face cage in Sual town using
plant-based feeds that lowered the use of fishmeal by 40 percent.
Westly Rosario, BFAR center chief here and executive director of the
National Integrated Fisheries Technology and Development Center, said they were
very happy with the result.
“Reducing the use of fishmeal by 40 percent is big (savings),” Rosario
said, adding since the 1970s, aquaculturists have been looking for an
alternative source of protein for animals and fish.
“The answer came with this technology from the United Soybean Board
(USB),” he said.
Rosario said they used floating extruded feeds based on USB formulation,
which was easily and efficiently digested by the milkfish.
He said they regularly tested the fish on the volume of feeds it could
consume at pleasure to make sure everything is eaten.
“Everything was consumed and hardly was there any leftover. The use of
feeds becomes effective and they (bangus) grow fast,” Rosario said.
The experiment showed the fish grew more than half a kilo in five
months. In ordinary commercial feed meal it only grew by as much as 300 grams
within the same period.
