Fig. 6. Top: Mean length of a sample of 20 adult Greenland halibut measured right after catch and after one, three and seven hours respectively. The two lines represent length measurements recorded by two different scientific crew members. Bottom: Annualised length increments of Greenland halibut from release to recapture versus length at release. Only individuals that had been at large for more than 300 days were included and box-plot outliers excluded. The thick dotted line represents a linear regression of the data.
