Abstract
Using data fiom the Norwegian bottorn trawl surveys in the Barents Sea in February
( 1989- 1996), the International O-group surveys in the Barents Sea (1 985-1 996) and
previously estimaied selectivity for the standard Norwegian sampling gears, effects on
estimates of mean length and weight at age are shown. For the younger fish rnean lengths
at age are biased upwards, the relative bias increasing with decreasing size.
