  1. Use a larger mesh size

    A replicated study in 2014–2015 of a fished area (bottom and surface) in the Arabian Sea, India (Gladston et al. 2017) found that using a larger mesh size of drift gillnets improved the size-selectivity of silver pomfret Pampus argenteus, compared to a smaller mesh size. The selectivity of pomfret (measured as the optimum length - the length at which fish were retained by the gear at the highest frequency) was greater with a larger mesh size of 130 mm compared to a smaller 110 mm mesh size (large: 155 cm, small: 131 mm). In addition, the authors noted that a mesh size of 166 mm was the optimum for the release of pomfret at size at first maturity (199 mm). Fortnightly commercial gillnet data were collected between August 2014–April 2015 from vessels fishing out of the landing centre of Satpati, using either 130 mm or 110 mm mesh sizes (see original paper for gear and vessel specifications). The nets were deployed at the surface, in the water column or bottom drifted in depths from 35–50 m. Vessel numbers and fishing duration (soak times) were not reported.
