Demersal fish | Quantity: number of hauls = 22 Description: Selectivity hauls for prawns, haddock and whiting. Six hauls were made using a standard 80mm cod-end, six hauls made using an 80mm cod-end with 90mm square mesh panel at 15-18m. Five hauls were made with an 80mm cod-end with 90mm square mesh panel at 9-12m and five hauls were made with a 100mm cod-end with 90mm square mesh panel at 9-12m. |
