In order to investigate the reliability of the maturity determination undertaken routinely onboard, gonads from 165 female haddock sampled during the Barents Sea trawl survey in January-March 1998, were studied in binocular. The size of the oocytes were measured, fitted to a 6-point maturity scale, and compared with the 5-point maturity scale. used.

Additionally, maturity at length and age was investigated for males and females using data from the winter surveys in 1989-1998 by fitting logistic curves.
