Figure S.1.3. Mean (± 2*SE) biomass of low trophic level feeding guilds of demersal fish, for polygons in the Sub-Arctic Barents Sea (Black dots and grey shading). Linear regression fit with 95% CI is shown in blue, and the statistical results are given in the top of each plot. A local smoother is added in red to assist visual interpretation of non-linear changes during the period. Stars indicate years with low sample size (< 5 trawls).
