8.2.1.2 Gears according to their mobility

1. Active nets:

These are moved by man-powers (group of persons) or machine power to encircle the shoal of fish and bring them to shore (bank). In active netting, the floats and sinkers are so adjusted as to keep the two ends of the net stretched apart during the entire operation. They include drag nets, bag nets, seine nets, trawls, purse seines, cast nets, scoop nets, movable traps, hook and line (angling).

2. Passive nets:

These remain stationary at a place and the fish moving around are caught or gilled. The net is either set at the bottom with the help of anchors and stakes (stake net), or suspended at intermediate depths with the help of drop-lines from larger buoys at the surface or suspended near the surface by its own float line, but the net is attached by means of ropes to larger sinkers at the bottom. They include various kinds of gill nets, ‘trammel’ nets, hook and line.
