Recruitment analyses of Sub-area 2 and Divisions 3KLMNO Greenland Halibut have modeled survey indices of juveniles measured by several survey series throughout the stock area. In 2004, the final analysis examined the estimated trends as predicted from ages 3-5 indices. This analysis is updated with the latest available survey information. We also examine the inclusion of the age-aggregated Spanish survey results from Div. 3NO. Results indicate that the 1993-1995 year-classes were the strongest produced over the time period considered (1978-2004). The 1996-2000 year-classes are estimated to be of below average strength; the 2001 cohort is estimated to be slightly above average, albeit with wide confidence intervals.
