A case study

A 1.2-KILOGRAM bangus (milkfish) saved on the Bureau of Fisheries and Aquatic Sources (BFAR) in Dagupan Metropolis will not value its weight in gold, however, it’s quick changing into an attraction due to its golden scales.

The Golden Bangus or Filipino Milkfish made its presence felt simply as Dagupan began actions for its 11th Bangus Pageant this month.

Rhe Golden Bangus or Filipino Milkfish, aged one 12 months and 4 months might be a freak of nature, mentioned Westly Rosario, BFAR heart chief. It has golden scales, head, fins, and tail, a deviation from the silver-colored milkfish.

“It’s in contrast to crimson tilapia which is produced by crossing two species. The golden bangus might be a freak of nature as a result of there is just one species of bangus, which is Chanos chanos,” he mentioned.

“The query now could be, since milkfish is named as such due to its milky coloration, how will we name now the golden bangus?” Rosario requested.
