OriginalversjonThis report is not to be cited without prior reference to the authors
Size selection of penned saithe was obtained by forcing the fish against an adjustable grid mounted in the end of net pens. The size selection was rather sharp, with a selection range of about 5 cm only. All fish forced against and passing through the grid survived the observation periods of 7-14 days, and there were no sign of external injuries caused by the selection process.
