One species of tilapia might be unwanted in some parts of the country and considered as a pest in fishponds for being invasive, but its kind is admirable for being “fatherly” and protective of their eggs, a fishery expert said. The male Tilapia Gloria, named as such for a mole below its jaw, takes care of its eggs (about 300 of them) by keeping them for 21 days inside its mouth to protect them against enemies and predators, said Westly Rosario, chief of the National Integrated Fisheries Development Technology Center of the Bureau of Fisheries and Aquatic Resources in this city, during the Kapisanan ng mga Brodkaster ng Pilipinas forum yesterday.
