Another net is used only by the women. In shape it is like a deep basin; its wide mouth is attached to a stout circle of rattan, and a wooden bar is tied across the mouth to serve as handle. With this the women catch the sucker fish in the shallow rapids, one turning up stones, the other catching in the net the fish that dart from beneath them.
Yet another mode of netting fish is to suspend a square of net attached by its corners to the ends of two crossed and downward bending sticks. The net is suspended by cords from its corners to the end of a long bamboo, which rests upon a post about its middle. The fisherman lowers the net into the water by raising the landward end of the bamboo lever, and when he sees fish swimming above it, attracted by a bait, he suddenly depresses his end of the bamboo, so as to bring the net quickly above the surface. On the coast drag nets are used.
The SELAMBO is used in small streams where fish are abundant. A fence of upright bamboos is built out from either bank, starting at opposite points and converging down stream to two points near the middle of the stream and about seven feet apart; where each terminates a stout pole is driven firmly into the bed of the river. These two poles are connected by a stout cross-piece lashed to them a little above the level of the water. The cross-piece forms a fulcrum for a pair of long poles joined together with cross-pieces, in such a way that their downstream ends almost meet, while up stream they diverge widely. They rest upon the fulcrum at a point about one-third of their length from their downstream ends. Between the widely divergent parts up stream from the fulcrum a net is loosely stretched. The net lies submerged until fish coming down stream are directed on to the net by the convergent fences. The fisherman stands on a rude platform grasping the handle-end, and, feeling the contacts of the fishes with the net, throws his weight upon the handle, so bringing the net quickly above the surface. Beside him he has a large cage of bamboo standing in the water, into which the fish are allowed to slide from the elevated net.
A rod and line and baited hook are also in common use. The Kayans make a hook of stout brass wire, cutting a single barb. The Kenyahs use a hook made of rattan thorns. A strip is cut from the surface of a rattan bearing two thorns about an inch apart; this is bent at its middle so that the cut surfaces of the two halves are brought into opposition, and the thorns, facing outward opposite one another, form the barbs. The line is tied to the bend, and the bait is placed over the tip projecting beyond the thorns. When the fish takes the hook into his mouth and swallows the bait, the barbs being released spring outward and secure the fish.
A rough kind of spoon bait is also used with rod and line.
Fish are taken also in traps. The most generally used is the BUBU. This varies in length from eighteen inches to eight feet or even more. The body of the trap is a conical cage of bamboo. From the wide mouth of the cone a second smaller flatter cone passes upwards within the outer one; the slender bamboo strips of which it is made come almost together in the centre, their inner ends being free and pliable. This is fixed beside the bank, its mouth turned down stream, and a few stakes are driven into the bed of the river to guide the fish into the mouth; or it may be laid in shallow water, two barriers of stones converging to its mouth. The fish working up stream pass in at the mouth, and, when they have passed the inner lips, cannot easily pass out again.
A still simpler trap consists merely of a long slender cone of bamboo strips. The fish entering the mouth and passing up to the confined space of the other end become wedged fast in it.
A Sea Dayak trap found in the south-west of Borneo is a cylindrical cage of bamboo attached to a pole driven vertically into the bed of the river. (Fig. 21). At one side of the cage is a circular aperture. Into this fits a section of bamboo, the end of which within the cage is cut into longitudinal strips that are made to converge, forming a cone, through the apex of which the fish can push his way into the cage, but which prevents his return. It is an application of the same valve principle as that used in the trap first described above.
A larger trap is the KILONG, which is used in the lower reaches of the rivers and also on the coast. It consists of a fence of stakes running out from the bank or shore into water some two fathoms in depth. The free end of the fence is wound in a spiral of about two turns. One or two gates are made between the outer and the inner chambers of the spiral on the side nearest to the bank or shore, and are left open when the trap is set. The fish, finding themselves confined by the fence, make for deeper water, and, entering the central chamber, do not readily return. The fisherman then closes the gate and takes out the fish with a landing net.
A prawn trap consists of a cylinder of heavy bark. One end is closed with a conical valve of bamboo strips like that of the two traps described above; the other flattened end is hinged to open for the extraction of the catch. The trap is baited with decaying cocoanut and thrown into the river with a long rattan attached to it and tied to a pole; the trap sinks to the bottom and is examined from time to time.
