Ling growth curves

Estimated growth curves for male (M) and female (F) ling from four different biological stocks in New Zealand waters (i.e., Chatham Rise, Campbell Plateau, Bounty Plateau, west coast South Island). Growth rates differ between areas, and female ling grow at a faster rate and reach a larger size than males in all areas. Credit: Peter Horn
