Ancau (ring net) This surrounding gear is a curtain-like net used for
catching sardines and/or sergestid shrimps. It is operated
during calm seasons in the bay and coastal areas. The operation
starts by scouting schools of fish and then surrounding the
school with the net (see Figure 7 and 8). The lower end of the net is then pursed
or closed by pulling the purse line attached to the rings
at the bottom of the net to trap the fish and the net is pulled
into the boat. The rectangular-shaped netting is about 300
m in length by 15 m depth. It is operated manually by 4-6
fishermen in a 9-12 m boat. The netting material is PA with
2.5 cm mesh while the float, sinker and purse seine lines
are made of PE. The ancau for sergestid shrimps or bubuk is
made PA knotless netting with finer mesh size of about 7 mm
stretched mesh.
