The Spanish vessel Tronio started the research plan in the 2012/13 season using the Spanish bottom longline system. One depletion experiments was completed in each of the SSRU surveyed (58.4.1H and 58.4.1G). Three prospecting-phase clusters of sets did not reach the established threshold to start the depletion.
A prospective estimation of the local biomass (BLOC) of the two localized areas where the depletion experiments were performed is done as well as an estimation of the biomass of the SSRUs (BSSRU), maximal and minimal, considering areas with high and low densities.
A summary of the activities and results from the survey is also presented related to the sampling scheme, collected samples and species involved.
