Bangus Profile

The entry of alien bangus in the Magsaysay market does not happen anymore in the city.

Dr. Rosario describes Dagupan bangus as a) physically good looking, tastier flesh and better texture b) it has small head, fine and smooth scales, bulging stomach, tender bones and a short lower fin tail c) if the belly is opened, there is no unpleasant odor because it feeds on the natural food called lablab

Why better bangus in Dagupan: Studies show that the following factors are present:

a) frequent flushing of the water in the rivers and the fishponds due to the perennial flooding which cleans the river and pond bottom of hydrogen sulfide causing microorganisms

b) Fishponds have less phosphorus

c) good mixture of brackishwater which favors good growth and balanced salinity with ranges from 10- 25 parts per thousand and temperature 25-32 ' C and good dissolved oxygen of 3-5 milligrams per liter due to the frequent chnage of tides since we are near the opening to the sea (Emma Molina, pic from fao.org)
