| Summary: | The development of the international shrimp (Pandalus borealis) fishery in NAFO Division 3M is described. A standard six nation data set is used to create a series of standardized catch per unit effort (CPUE) indices with the purpose of tracking the status of the Flemish Cap shrimp stock. The standardized CPUE was at a high level in 2003. A provisional CPUE of Iceland alone shows a CPUE below average in 2004. In 2003 a peak catch of shrimp was caught at the Flemish Cap of some 62 000 tons. An international observer database of length frequencies was used for ageing the shrimp. Indices of female stock are calculated from this using the standardized CPUE series. Spawning Stock Biomass index (SSB) was obtained from the EU survey and the Faroese surveys to year 2003. Recruitment indices were determined from the Faroese surveys both the main trawl and the juvenile net attached to the trawl. to 2003 showing that the 2001 year-class was about average. A good recruitment of one year olds was detected in the EU survey of 2003 and preliminary information from the Icelandic observer samples in late 2003 and early 2004 also show the presence of a prominent 2002 year-class. 1. |
