Fig. 22. Relationship between mean triglyceride (TG) levels in the liver and mean melano-macrophage density (MMD) in the kidney in juvenile masu salmon. The plots in this figure express the means of TG and MMD in juvenile population at each station and time. Spearman's rank correlation coefficient was used as statistical analysis. The dotted line shows the linear correlation [MMD] = 0.622–0.359 [TG] (r = 0.601, P < 0.05). There were no juveniles caught at station 5 in July. Modified from Sci. Rep. Hokkaido Salmon Freshwater Fish. Res.
