1. To determine the effect of the position of a 90mm square mesh panel on the selectivity of a 100mm diamond mesh cod-end, constructed from 5mm diameter double twine, attached to a commercial seine net.
2. To measure the selectivity of the same cod-end with no square mesh panel.
3. If time allows, to measure the selectivity of a 100mm diamond mesh cod-end without a lifting bag or square mesh panel.
