Hi I am a Fish Biologist currently working in Manila and North Borneo in projects that aim for an ecologically more sustainable tuna fishery. Let's see how far we get it...

    Mindoro-Pandan Island

     February 24, 2018 on the Philippines ⋅ ⛅ 20 °C

    A short trip to Pandan Island to the west of Mindoro. I should spend more weekends like this! Absolutely great! I didn't expect a lot from the diving there and therefore and didn't bring my underwater camera...big mistake!

    Fishmarkets

     February 7, 2018 in Malaysia ⋅ ⛅ 26 °C

    Of course, I love fish markets! As a fish biologist, it is my natural habitat! Whereas markets selling terrestrial meat products usually harbour a handful of species only (pork, beef, chicken, lamb and perhaps goat if you are lucky) fish markets often display dozens of fish species...and then we didn't even start with the arthropods and molluscs diversity found as well (div. species of lobsters, crabs, shrimps, octopuses, mussles etc).

    However, there is a clear downside of the whole fish trading thing! Especially on small scale fish markets in developing countries none of the fish which get landed are ever reportet, there is no control about iligeal fish species and undersized fish being sold. It is assumed that 50% of the worlds consumed fish is caught and traded by small scale fisheries. So try to make a correct stock assumption with this data basis! #futurechalange :-)    Read more

    The Fishermen of Mabul Island

     February 1, 2018 in Malaysia ⋅ ❄️ -1 °C

    I am back on Borneo again for our Sustainable Tuna Project in the Sabah region (northeastern corner of Borneo). Janni, the chief of the fishermen of Mabul Island, invited me to stay at his place for three days. I have been to Jannis place before and I knew that I definitely should not miss this opportunity...being at his place with his family means to go squid fishing with his boys, diving in the world-famous coral reefs just outside his doorstep and eating all the delicious things the sea has to offer. Also, I had to collect some fishing vessel data from the fishermen we are collaborating with...the perfect excuse to go there and to enjoy a weekend on Mabul Island :-)Read more

    Malay Wedding

     January 29, 2018 in Malaysia ⋅ ☀️ 23 °C

    I have been invited to my first Malay, and actually also my first Islamic wedding. Some very distant relative from one of the tuna boys got married but that was no reason not to join for the free meals there and to bring the Swiss guy as a general attraction...As always, someone organised a car, another one organised fuel and the third one a driver. Off we went through the endless palm oil fields in Borneo and arrived just in time for lunch. Before every meal, I think that they will struggle to serve something I didn't already have on my plate...but as always I was wrong. They took fresh coconut flesh, put it in a fire and completely burned it. Then they took the remaining ashes out of the fire and made a (of course completely black) sauce for the meat with it. It was quite good and if you happen to get a food poisoning you already took your first dose of activated charcoal...with this in mind I felt completely safe and asked for a second serving :-)Read more

    Binondo-The world's oldest Chinatown

     January 21, 2018 on the Philippines ⋅ ⛅ 29 °C

    Founded in 1594 by the Spanish to keep Chinese immigrants out of Intramuros (where they wanted to live for themselves), Binondo is the world's oldest Chinatown. And as everywhere where Spaniards settled on a piece of land they were soon very busy converting whatever beliefs to Christianity...and once again they succeeded. To a frightening degree! If large proportions of the population think that the pope is a wimp because he is not pushing Christianity hard enough you start to become very quiet as an evolutionary biologist :-)Read more

    Intramuros Manila

     January 5, 2018 on the Philippines ⋅ ⛅ 30 °C

    Let's say it like this...If you are looking for an Asian city that has plenty to offer from a cultural point of view and which will please your eyes with its charming corners and views...well, in this case, you are better off skipping Manila from your list.

    However, there is one corner in this sea of concrete, where you can still find buildings dating back to the Spanish colonial time which lasted from 1565 to the end of the 19th century. Intramuros, as the name suggests, is completely surrounded by the old Spanish city wall and indeed quite pretty...well, pretty to the degree that I forgot to take pictures of the buildings.Read more

    Christmas in Manila

     December 29, 2017 on the Philippines ⋅ ⛅ 28 °C

    Every party in the Philippines can easily be summarized with just four words: drinking, smoking, gambling and karaoke (everywhere, all the time!)

    These four activities are the pillars on which every party, every event and just anything that is related to joy and happiness, is based...So I guess no further explanation of my Christmas here is needed.Read more

    Lake Taal

     December 14, 2017 on the Philippines ⋅ ⛅ 10 °C

    A few hours outside of Manila in the province of Batangas lies Lake Taal, the Phillippines third largest lake, filling the Taal caldera. The reason it is quite well known is that in the middle of Lake Taal there is the Taal Volcano Island on which you will find another small crater lake in which in turn there is another tiny volcanic island...island in lake on island in lake...the Philippines!Read more

    The Fishermen of Mabul Island

     December 8, 2017 in Malaysia ⋅ ⛅ 28 °C

    We were on Mabul Island to get to know the local fishermen there and to learn about their ancient fishing technique which allows fishing for big yellowfin tuna with less than 2% bycatch. A stone, a single hook and a handline is all it takes.
