Grid-sorting of penned saithe
Original version
This report is not to be cited without prior reference to the authorsAbstract
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.
