Growth of the Barents Sea capelin of the year-classes 1967-70
Otoliths of the 1967-70 year-classes of the Barents Sea capelin have been analyzed. For otoliths with radius < 0,74 mm there was a close, linear relation between fish length and otolith radia. For larger otoliths the correlation was less strong. Radia of the first hyaline zones, measured in fish...
