Searching robis for occurrence data of multiple fish species in the Baltic Sea reveals that post 2011, the dominant data sources from DATRAS (https://www.ices.dk/data/data-portals/Pages/DATRAS.aspx) trawl surveys decline precipitously. Genuine decline is obviously at play but is there any chance occurrences are not fully updated? See attached example plot for Cod (Gadus morhua).
