Gill nets

2. Andang karan (trammel net)
     This is an entangling net of measuring about 270 to 460 m in length and 1.5 m depth. The gear is made of three layers of nylon nets that are fused together forming a curtain-like wall (see Figure 15). The outer walls of the net have a stretched mesh size of 270 mm, while the inner wall have mesh sizes varying between 38 mm, 45 mm and 48 mm. Due to the small twine diameter of the net, appendages of shrimps and crabs are easily entangled and are usually difficult to remove and often damage the netting. The andang karan is used to catch fish in the open waters off Tutong and Belait districts. The net used for catching shrimps have smaller meshes (2.5 – 4.5 cm). The andang karan designed for shrimps is set adrift with the tidal current and traps shrimps around the flexed abdomen. Fishermen operate alone or in pairs during daylight hours using two andang units alternately. Each unit is 120 – 150 m long by 3.5 m deep. Fishermen follow shrimp concentrations within the Brunei estuary and during season of Nov-Dec, off the northern coast as far as Berakas and Jerudong (Silvestre, et al).
