FIGURE 5 in Population ecology and juvenile density hotspots of thornback ray (Raja clavata) around the Shetland Islands, Scotland
FIGURE 5 Spatial distribution of juvenile Raja clavata (<60 cm) catch per unit effort (CPUE) from annual Shetland inshore fish surveys (SIFS) conducted between 2017 and 2022. Blue crosses indicate inshore habitat surveys (20–50 m water depth), and red crosses indicate shallow water habitat surveys (50–150 m water depth). The size of circle indicates CPUE. The location of each R. clavata individual was assigned as the midpoint of the associated tow.
FIGURE 2 in Population ecology and juvenile density hotspots of thornback ray (Raja clavata) around the Shetland Islands, Scotland
FIGURE 2 Catch per unit effort (CPUE) of Raja clavata for the shallow (red) (2017–2022) and inshore (blue) (2011–2022) survey locations. The mean result is shown by solid lines, and the shaded area represents the variability between tows (standard error).
FIGURE 1 in Population ecology and juvenile density hotspots of thornback ray (Raja clavata) around the Shetland Islands, Scotland
FIGURE 1 Inshore (blue) and shallow (red) survey tow habitats during Shetland Inshore Fish Survey. Tows identified by their station code and corresponding fishing grounds, for example, HA01, Fitful Head.
FIGURE 4 in Population ecology and juvenile density hotspots of thornback ray (Raja clavata) around the Shetland Islands, Scotland
FIGURE 4 Non-metric multidimensional scaling (nMDS) plot showing ordinations generated from a Bray–Curtis similarity matrix on Raja clavata catch per unit effort (CPUE) Bray-Curtis similarities between shallow water and inshore habitat tow locations. Surveys are grouped into shallow (red) and inshore (blue) habitats. Labels represent survey habitat and year, for example, I22 = Inshore survey conducted in 2022. nMDS plot 2D stress is 0.06, indicating a clear distinction of the two clusters (dashed lines). Inset picture shows two Raja clavata sampled in a tow; basket diameter at base is 35 cm.
