Recruitment analyses of Sub-area 2 and Divisions 3KLMNO Greenland Halibut have modeled survey indices of juveniles measured by several survey seri es throughout the stock area. In 2005, the final analysis examined the estimated trends as predicted from ages 3-5 indices. We review the rationale for using these ages, and subsequently propose using the age 1-4 data in the current assessment. Estimates of year-cl ass strength indicate that the 1993-1995 year-classes were the strongest produced over the time period considered. The 2000-2002 year-cl asses are estimated to be of about average strength, and based upon the available data, the 2003 and 2004 cohorts are estimated to be poor.
