The Icelandic shrimp fishery consists of three separated stocks: inshore, offshore and Dhorn bank/Denmark Strait populations which differ genetically (Jónsdóttir et al., 1998) and in size, maximum length and length at sexual maturity (Skúladóttir and Pétursson, 1999). Assessment and management measures are performed to each stock. The inshore fishery has been closed in recent years, with the exception of Snæfellsnes area and Arnarfjörður (IMFA, undated 1).
