  1. Use a larger mesh size

    A replicated, controlled study in 1997-1998 in an area of seabed in the Aegean Sea, Greece (Stergiou & Erzini 2002) reported that larger mesh sizes in a gillnet caught fewer unwanted small fish compared to smaller mesh sizes. Results were not tested for statistical significance. The most frequent length of fish caught in nets of increasing mesh size between 22 mm and 28 mm mesh increased for seven of seven species, for two of two species between 22 mm and 24 mm mesh and for one of one species between 22 mm and 26 mm mesh (see original paper for species individual data). A total of 42 fishing trials took place in September 1997–October 1998 using gillnets of 22 mm, 24 mm, 26 mm and 28 mm mesh size. Nets of each mesh size were set in lengths of 1,000 m (0.30 mm diameter multi-monofilament nylon) and at depths of 4–90 m in traditional fishing grounds.
