Ulang or Giant Freshwater Shrimp (Macrobrachium rosenbergii) used to thrive in several rivers and waterways throughout the Philippines. ulang1They needed unsullied fresh water or somewhat brackish (part salt, part fresh water) conditions to thrive in the wild. In the last few decades they became rarer and rarer from natural sources as our rivers got more and more polluted. But we have now successfully domesticated the shrimp and raise them in shrimp ponds or together with rice crops in rice fields and nearby ponds. Large (compared to shrimp) and meaty, they are a more reasonably priced alternative to lobster and about the same price as prawns. The most common usage I have found is in a terrific ulang sinigang (shrimp with a sour broth). They differ from prawns in that their heads are unusually large and they have these long thin claws (not obvious in these pictures as I think the vendor removed them!). They have bright blue and sometimes yellow striped colored shells and legs.

Ulang can grow up to a foot long and weigh about 350 grams (or 3 pieces to a kilo). ulang3The ones I photographed here were about half that weight at 6 pieces to a kilo and they cost P380 a kilo. I suspect much of that potential length would include the long thin claws. Native to the Philippines, but related to dozens or hundreds of freshwater shrimp throughout the world, this is a food source that was unfamiliar to many Filipinos in the last two generations due to its disappearance from rivers and streams. However, aquaculture is bringing it back quite successfully. If you have never tasted ulang before, try it. Treat them like large prawns though I find the meat can be denser and dries out faster when it is roasted or grilled. Overcooking them makes them tough. For a first taste, try them in a sinigang made with sour tamarind or alternatively, kamias fruit.

In some material I came across doing research for this post, some ulang4local sources refer to ulang as freshwater shrimp or crayfish. They are not crayfish as the latter are small freshwater lobster and there are none of those in the tropics except in Papua New Guinea and Northern Australia. For the curious, ulang are also known as udang in Ilocos and Cagayan (also the word for shrimp in Malaysia and Indonesia); paje in Palawan; kalig in Leyte, kissing-kissing in Pangasinan, etc., according to an article by Rose De La Cruz on the Palawan.com website.

    I have eaten them when we spent holidays in Samar where rivers way back then were so clear and clean. This was late 70s and early 80’s. I remember us catching cat fish too and many other goodies from the river!

    I was lucky then to have seen Samar and Leyte when only few people would dare to visit coz of the activities of the NPA. But we have families out there!
    We look forward to our move tomorrow, in our area is full of gastro shops. One is a seafood place where we can get fresh crabs, prawns and alaska king crabs.

    I’m interested about freshwater shrimp because most of our barrio folks rely on this commodity as their everyday viand aside from tilapia. Usually they catch these shrimps when the river starts to rise due to heavy rains using a mosquito net. Also, a friend of mine requested me some information about freshwater shrimp…its biology, production management & postharvest. Actually, I’m connected with the Department of Agriculture & one of the staff of Techno Gabay Center based at the Regional Integrated Agricultural Research Center, Balinsasayao, Abuyog, Leyte. Hope you can feature more about this commodity in your future issues… Thanks a lot & more power!…

    From Iloilo po ako. Tawag sa amin niyan ay Urang. Naalala ko noong maliit pa ako palaging may nakasamang Ulang pag bibili ng hipon ang lola ko. Tapos nang magka-aquarium kami, nilagyan ko nang mga 4 siguro galing sa ilong malapit sa amin. Nakakatuwa silang tingnan (kaso hinuhuli nila minsan yung ibang isda). Malaki rin siguro ang potential nila sa pet industry, especially sa West. Na realize ko yan dahil nangdito na ako sa Canada (mga tao dito kahit anu nalang ang inaalagaan).

    May isa pang klaseng freshwater shrimp. Yung katawan ay tulad din ng ulang kaso yung pincers niya ay malaki tapos di masyadong mahaba. Anong tawag kaya dito? Tagal ko nang di nakakita nito. Medyo rare sila kasi.

    I tried ulang today in Bulacan. Wow. The head fat is like taba ng talangka, very rich. The meat is very dense, but very substansial.

    Our host gave us a package to bring home. Hinuli daw sa dam.

    I’m gonna experiment with these: use the heads for some sort of bisque, and the tails for grilling, baking, turning into Thermidore, and in a couple of pasta sauces.
