Abstract

The aim of the Workshop on Small Scale Fisheries and Geo-Spatial Data 2 (WKSSFGEO2) was to continue the work developed during WKSSFGEO, namely on analysis of the high-resolution geo-spatial data in small-scale fisheries (SSF), as well as large-scale fisheries (LSF) taking into consideration low duration fishing events. During this workshop, an open database of examples of SSF across the EU, including a script to anonymize the data, was produced. The data set cur-rently available has 9 full case studies from different countries, gears, geo-position recordings and temporal intervals, is fully functional and openly available on ICES github. Various methods to infer fishing activities were compared, and the main issues and recommendations were dis-cussed. Testing of the effect of temporal resolution in the data using the example data base was initiated but further work is required on this aspect. Based on preliminary analysis, it was concluded that a conservative approach of a ‘ping rate’ of 30 secs (to obtain a 1 min temporal interval) is recom-mended if a generalisation is to be made that is applicable in all Metiers and that can be used to estimate all EU Multiannual Programme for data collection variables. Based on available data sources (EU FDI, ICES VMS/Logbook Data Call, Global Fishing Watch AIS) an overview of small-scale fisheries (SSF) in EU Waters, visualized in figures, maps and tables was created. It was clear that it is difficult to directly compare data from the three available sources as each have different issues, e.g., different vessel length groups, covering fisheries from different countries and different legislation behind the data sources. Based on FDI data we can see that the passive gears are responsible for most fishing effort and that around ⅓ fishing effort from EU vessels in area 27 (North Atlantic) is from mobile bottom-contacting gears. In area 37 (Mediterranean and Black Sea) the proportion of fishing effort from mobile bottom-contacting gears is smaller. With regards to position data from the SSF, the VMS data can provide good coverage for vessels larger than 12 m, and the AIS could supplement for the smaller vessels, but the analysis comparing the fishing days by vessel length classes for the three data sources show that it is not a complete picture. The Global Fishing Watch data has shown another useful addi-tional source which could be useful in future analysis. The resulting maps indicate significant gaps in data or data availability and a complete profile of SSF in EU cannot yet be produced with these data. WKSSFGEO2 discussed the opportunities, challenges and benefits for an EU-wide tracking sys-tem for small-scale fisheries vessels and this report provides a guidance document with various recommendations on ways forward
