| Abstract: | Significant differences were found at the synaptophysin ( Syp I) locus between two groups of Icelandic cod Gadus morhua ; Loftstaõahraun (spawning ground), Reykjanesgrunn and Eyrabakkabugur (feeding grounds) on the one hand and Kantur (spawning ground) and Austfjarõadjúp (feeding ground) on the other. There was also a considerable genetic heterogeneity within the former group. The results indicate that the cod in south and south-east Icelandic waters do not belong to one panmictic population. |
