Abstract
Comparisons of scale and otolith age readings have been made for haddock from Subareas 4 and 5 of the ICNAF Convention Area. Percentage of disagreeing readings increases with increasing average age of the fish. In cases of disagreement, scale ages are consistently lower than otolith ages for fish above about 7 years of age in Subarea 5, and for practically all ages in Subarea 4. Variation in results from the 2 methods produces differences in relative strengths of year-classes but has little effect on growth rates.
