| Summary: | is found. Namely, whether or not recruitment to the adult slope population is still occurring even though the bottom trawl estimates of small Greenland turbot on the shelf has been at low levels since the early 1980s. In 2000 a pilot survey of the slope region was conducted. Analyses of this work has been completed and a new survey will commence in the summer of 2002. 4.2 Introduction Greenland turbot (Reinhardtius hippoglossoides) within the US 200-mile exclusive economic zone are mainly distributed in the eastern Bering Sea (EBS) and Aleutian Islands region. Juveniles are believed to spend the first 3 or 4 years of their lives on the continental shelf and then move to the continental slope (Alton et al. 1988). Juveniles are absent in the Aleutian Islands regions, suggesting that the population in the Aleutians originates from the EBS or elsewhere. In this assessment we assume that the Greenland turbot found in the two regions represent a single management stock. Prior to 1985 Gree |
