Fig. 6. Contour plot showing the cod larval weight (after 100 days) standardized relative to the highest average body weight (at day 100) at each day of release (this removes the effect of season, and highlights latitudinal differences), as a function of latitude and date of release. The latitudes (oN) for the different spawning grounds are from south to north; Vikna (64.9), Vega (65.6), Røst (67.5), Vestfjorden (68.0), Moskenesgrunnen (68.4) and Malangsgrunnen (70.0).
