Beach seine net consists of two long wings to which a bunt
or a bag is attached. The wings are either straight of tapered pieces of netting hung to a weighted
foot rope and kept in the vertical position by the float line. Because the working depths of the beach seine
has to be level with to the depth of the water, beach seines operating on steep slopes have tapered wings,
whereas those fished in shallow waters have straight wings. In most beach seines, the mesh size decreases
gradually from wing tip to bunt. The length of the beach seine is from 60 meter to 300 meter in length and
depth is 2 meter to 30 meter. The mesh size is 5 mm to 10 mm at the bunt section and 24 mm to 150 mm at wings.
Some area, the mud ball about 0.8 kg are used as sinker at foot rope.
Beach seines are set from the beach from the
starting point in a semi-circle pattern to another point of the beach, forming the distance between those points roughly
half to one third of the diameter of the semi-circle. To increase the area swept by the beach seine,
long ropes are attached to the wing tips. The beach seine is hauled in by teams of fishermen from both ends,
at equal speed. First the ropes are hauled in then the wings and finally the bunt or bag, approaching
each other as the radius of the encircled area decreases.
