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.
