| Abstract: | Bathymetric and regional variation in condition of Icelandic cod Gadus morhua in autumn is compared to that previously observed in spring. Once again, contradicting patterns in the hepato-somatic index and a morphometric index of fish condition were observed. The relevance of this persistent spatial variation in condition in relation to emerging evidence of behavioural types is discussed. |
