This report introduces the URCHIN project, funded by the Northern Peripheries and Arctic Programme (NPA). It then describes the main techniques used for stock monitoring in sea urchin fisheries around the world, including techniques used in the NPA. Trials in Norway and Iceland run with the aim to develop cheap, effective and reliable methods of stock monitoring suitable for the environmental conditions found in the NPA are described. These include methods for both surveying new fishing areas as well as scientific monitoring. This report describes suitable sea urchin stock assessment techniques for both scenarios and describes the methodology to all participating NPA countries. It also makes recommendations for the most suitable methods for each of the participating NPA countries (Norway, Iceland, Ireland and Greenland).
