Drift gill net

              There are various kinds of drift gill nets.  Nylon multifilament is most often used as the netting material, but the yarn size varies from 210 d/4 to 210 d/18.  Green colour nets are commonly used.  Some drift gill nets, especially those for Spanish mackerel and pomfret, have a width of saran nylon netting attached along the bottom edge.  This acts as a sinker because the specific gravity of saran nylon yarn is greater than that of nylon multifilament.

              The drift gill net for Spanish mackerel is operated on a large scale.  Netting yarns vary from 210 d/9 to 210 d/18, the size of mesh is around 6-10 cm, and the height of net ranges from 4.5 to 12 meters.
