The work developed under SSF, ToR b), continued to develop best practice guidelines on SSF data collection, with quantitative analyses on the coverage/completeness of fishing activity. PCA analysis was carried out of data incompleteness issue or over-declaration to build a risk’ map where each country*area is positioned (Section 4.2). The sub-group reviewed the proposed CL and CE data formats from RDBES core group to accommodate ‘scientific’ and ‘official’ estimates to cover SSF data gaps. One of the main issues with this proposal was the lack of transparency that needs to be addressed (Section 4.4). The strengths and weakness of using ERS for monitoring SSF were also assessed (Section 4.3).
Under ToR c), sampling and estimation of by-catch species, the main focus during this year’s meeting was to review the definitions of sorting, hauling and slipping processes for each gear type and how to implement in on-board protocols (section 5.2); and a detailed description on how to sample protected species on-board commercial vessels (Section 5.3). The RDBES structure was also reviewed to assess if it is suitable to accommodate the necessary information for WGBYC needs (Section 5.1).
WGCATCH continued to review the work developed under the RDBES. The documentation of the current estimation procedures will contribute to the prioritization of the estimation methods to be implemented as standard methods in the RDBES system. The series of practical workshops, proposed by WGCATCH, on estimation procedures for the next 3 years to produce best practice guidelines for choosing methods and variables used to expand commercial sampling data will also contribute to the development of the RDBES, as they will focus on the best statistical methods to expand the commercial sampling data.
Given that this is the third year of the current term of WGCATCH, future needs in line with the ICES objectives and Science plan were identified and a future work plan was proposed.
