(Glossogobius giuris) is a freshwater fish native to Mainit Lake. It is called “biya” in Tagalog and “white goby or tank goby” in English. The term “pidjanga” is also sometimes fondly used to refer to the Mainitnons, the people of the Municipality of Mainit, a town in Southern Philippines. This blog hopes to capture potentials of Migrants Pidjangas for the Development of our Town by attempting to document development issues, folk stories, and current concerns, about the Pidjanga — both the fish and the people.

Glossogobius giuris

Is the Pidjanga (Glossogobius giuris) endemic to Lake Mainit or not?

Dili kuno...

But here's a 1990 document reflecting that Glossogobius giuris as one of the main species under Gobiidae which the Pidjanga belongs too. It is supported by several papers starting from Manacop of 1937.

Would greatly appreciate if someone out there can help the Pidjanga Blog get the papers of Herre (1953), Gracia (1962), Pambid (1970), Gracia and Magsumbol (1981), and Gracia (1985).

I already have copies of Manacop (1937) and Lewis (1973)
