Abstract: A unique filter net fishing for small shrimp (Sergestes sp.) of 1-2cm in carapace length was observed in operation near the mouth of Cagayan River in Aparri, Cagayan, northern Philippines. The fishing operation made use of two posing water flows, one coming from the river and the other from the sea. The filter net locally called "banvar" made of synthetic netting materials of various meshes has a mouth opening of 4m deep by 10-15m wide which is varied with the length of the fishing boat used. The net with no float and sinker is a long conical shape and during operation it is tied on to two log stretchers after which logs are vertically fixed at the side of the boat placing the in position underwater. A fishing operation lasts for about one to two hours and this is repeated for five to six times. The average daily catch ranges from 0.6-1.5 tons of small shrimps which could sell for US$ 340-450. A sewed boat locally called "barangay" of more than 12m long is used for the fishing operation. The boat consists of a flat keel, a pair of side and intermediate plankings, a stem post and a transom. These parts are sewed together using galavanized wires with beams and side stringers. The boat hull made of thick plankings of red rauan resembles a Japanese type wooden craft looking at the profiles. A smaller sewed boat locally called "bote" of less than 8m long is often used to transport the shrimps caught to landing place.
