Nephrops are limited to a muddy habitat and the distribution of suitable sediment defines the species distribution. The stocks are assessed as seven separate functional units (FUs) as shown in Figure 5.4.21.1. There are also some smaller catches from areas outside these functional units as well as all of FU 18 which are not formally assessed. The advice for Nephrops stocks is given by functional unit in Sections 5.4.21.1–7.
