(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.

Bugwan (Hypseleotris agilis)

Response letter of LMDA to a graduate student of Oregon State University conducting a research on Hypseleotris agilis (locally known in Mainit as Bugwan)

Greetings from Lake Mainit!

The species you mentioned "hypseleotris agilis" is locally known as "Bugwan". According to Dr. P. Escudero a professor from MSU, Marawi City who visited the Lake Mainit in early 1994 that "bugwan" is endemic in Lake Mainit and was accidentally introduced in Lake Lanao when they took some species like Carpa and Tilapia from the BFAR hatchery in Kitcharao, Agusan del Norte for fish dispersal in Lake Lanao. According to him, the Catalog of Philippine Fishes compiled by an Americans as early as 1910, Bugwan was only found in Surigao when Lake Mainit was still part of Surigao District.

Dr. Escudero was amazed to find out that Pidjanga (Glossogobius giurus) and Bugwan (Hypseleotris agilis) co-exist in Lake Mainit and they were caught at the same time and of the same fishing technique, without being a threat to each other. While in Lake Lanao, the native fish was declining due to introduction of Bugwan. This needs further research, indeed.

This phenomenon could be possible in Lake Mainit because it is the deepest lake in the Philippines with an average mean depth of 150 meters. Lake Mainit is also classified as an oligotrophic lake based on its physico-chemical, natural productivity, optical properties and morphometric characteristics (Tumanda, et. al. of MSU-Naawan Research Team).

I had a photocopy of the study by Mr. Galicia and Mr. Lopez of BFAR, Inland Fisheries and Aquatic Division which was presented to International Workshop in Muruay Garden Hotel, Bangkok, Thailand in Feb. 2000 entitled "The Biology and Fishery of Indigenous Gobies of Mainit Lake". The paper presents the results of a 17-month study on the biology, fishery and population structures of Gobies (Order Gobioidea), Glossogobius giurus "Pidjanga" (Family Gobidea) and Hypseleotris agilis "Bugwan" (Family Eleotridea) caught by beach seine in Lake Mainit from August 1997 to December 1998. The study is a component of a research grant funded by the Spanish Government.

For more information you can visit the MSU-Naawan Reasearch Team at Naawan, Misamis Oriental.

They had also an ongoing research entitled "The Sustainability Fishery Management Program for Lake Mainit", The phase 1 is about stock assessment and species inventory of aquatic life.

Thank you.

Project Director, LMDA

Pidjanga notes: Salamat karadjaw Mano Kaiser for responding promptly to the inquiry of the researcher. We have successfully linked her too to the BFAR, MSU Naawam, MSU Marawi, and DOST. Salamat karadjaw Ngay Peter Sy for referring the researcher to me. The study and the relevant researches on this will greatly help in promoting sustainable development for our beloved Lake Mainit. This subject is also of very special interest to me as I hope to build up a substantive database of information about our lake and hopefully store them online at, which I singlehandedly maintain. In the near future, I will personally request the Pidjanga Blog community to contribute any information or write ups or photos about Lake Mainit and make its online presence a real and substantive Cyber Danao. I trust that you'll help me on this. Zimm

Pidjanga of UN Country Team with GMA, JDV

If you have grabbed a copy of today's (October 11, 2007) issue of Manila Bulletin (or has visited its online version -, you might have seen your fellow Pidjanga (The Pidjanga Blogger) in front page and standing as a member of the United Nations Country Team (UNCT) in the Philippines having a Photo Op with President GMA and House Speaker JDV.

The UN presented to the government of the Philippines the Mid-Term Progress report on the achievement of the Millennium Development Goals. It seems that we have high probability of achieving our goals in the area of poverty and hunger, child mortality, HIV and malaria, and environment by 2015. However, we need to scale up our responses to be able to address the problem of universal primary education, maternal health, and reproductive health.

I am not sure if any of your folks in Mainit have used the term "taburete". My Lolo Bitoy and Lola Tisay use the term very often referring to a type of chair without back and arm rests now commonly called "stool" both in Minainit and in English.

Here's one that is rightly called "INGKORANAN" (or chair). I wrote it in capital letters signifying its size... this must be the LARGEST ingkoranan in the world (well, the largest that I have seen).

This is in front of the UN Headquarters in Geneva. This wasn't here last year. This new Geneva landmark must have been constructed fairly recently.

I did not see any official name of this mammoth sculpture, so may I propose that it be called the "Three-legged Taburete of Geneva" (Three-legged Chair of Geneva).

Still below that giant taburete... but with the flags of UN Member States in the background.

Hmmm... hain na kaha an kodak nan ato fiesta!!! Kun aya pa gadjud... I'll just start posting photos of Mainit landmarks which I took last August 2007.
