If there is one thing Ilonggos have to learn to earn profit, it would be the farming of "ulang" or the freshwater prawn, macrobrachium rosenbergii. Old folks said that ulang used to thrive at the Jaro River way before the World War II. However, the murky environment which grew over the years, took its toll. Nowadays, ulang could only be found at certain forested areas.
