The overarching objective of the FishPi project is to strengthen regional cooperation in the area of fisheries data collection. The role of every case study within the project is to bring together the countries with the most involvement in the fisheries selected to coordinate and cooperate in the search of a probabilistic regional sampling design. To this aim, case study 4 (CS4) is focused in the Northern and Southern Hake stocks. The work done in the case study include the description of the fishery at a regional level, the compilation of the present national sampling activity, the compilation of the logbooks and/or sales notes from 2013 and 2014 –to have a single regional data set of all trips of interest in the region– and different runs of simulations to test the selected sampling scenarios and stratifications. Finally, an objective evaluation of the performance of these regional designs is expected to understand the changes needed compared to the present situation. This document ...
