| Summary: | Previous assessments of Northern Shrimp (Pandalus borealis) in NAFO Divisions 3LNO used numbers of shrimp at age 2 as the index of recruitment. Due to an incomplete 2004 autumn survey there was no autumn estimate of the 2002 year-class. For this reason, to permit use of more information from the surveys ’ numbers-at-age matrices, it was decided to model the year-class strength from the spring and autumn Canadian survey series. Model results indicated that the 2002 and 2004 year-classes were above average, while the 2003 year-class was below average. |
