With the introduction of the landing obligation in the EU common fisheries policy, there has been several initiatives to reduce unwanted catches of quota-regulated species. In this study, we present a flexible sorting grid as a potential solution for the problem of bycatch of saithe in the pelagic herring trawl fishery in the Skagerrak. The development of the grid was initiated by the industry and finalised through an industry-science collaboration project. The selectivity of the grid was evaluated through the use of an underwater camera system during conventional trawling with an industrial pelagic herring trawler. The results showed that the grid reduced the bycatch by more than 90%, from approximately 5% to 0.5% of the total catch. Given the scale of the pelagic fishery, this reduction could decrease unwanted bycatch of saithe by up to 1000 tonnes per year in the Skagerrak alone. These results were communicated to national industry and management representatives and to responsible EU management bodies and advisory councils. The work conducted within the project also drew interest at the yearly negotiations between EU and Norway. In their agreement for 2018, the EU and Norway agreed to establish a working group on technical measures in the Skagerrak tasked with reviewing selectivity of pelagic trawls as part of the terms of reference. However, in the agreed record of the delegations, the question of pelagic gear selectivity in the Skagerrak was a non-issue, although they concluded that the demersal bycatch can be substantial, that a sorting grid can reduce this bycatch and a sorting grid remains mandatory for Norwegian vessels in the Skagerrak. We argue that this result can be seen as a missed opportunity for the EU to reduce unaccounted bycatch in the Skagerrak and ensure better implementation of the landing obligation.

Under hösten/vintern 2015/2016 genomförde sekretariatet för selektivt fiske,vid institutionen för akvatiska resurser (SLU-Aqua) tillsammans med svenskt yrkesfiske, nio projekt inom ramen för regeringsuppdraget selektivt fiske. Den övergripande målsättningen för alla projekt inom selektivt fiske är att underlätta införandet av den landningsskyldighet som beslutats i och med reformen av EU:s gemensamma fiskeripolitik. Projekten syftade därför till att minska oönskad fångst i svenskt fiske antingen genom att utveckla befintliga fiskemetoder (framförallt inom trålfiske) eller genom att utveckla alternativa fiskemetoder (främst passiva redskap såsom fällor och burar). 1. "Kombinationsrist för utsortering av fisk och små räkor" (HaV Dnr 1718-15) 2. "Selektivitet anpassad för små räktrålare" (HaV Dnr 1488-16) 3. "Räkburar" (HaV Dnr 1892-15) 4. "Vidareutveckling av storleksselektiv kräftrist Halland" (HaV Dnr 1717-15) 5. "Trål för fångst av plattfisk och stor torsk-rist/stormaskig trål" (HaV Dnr 1716-15) 6. "Förbättrad selektivitet i torsktrålar i Östersjön" (HaV Dnr 2384-15) 7. "Utsortering av gråsej i pelagiska trålar" (HaV Dnr 1715-15) 8. "Selektiv laxfälla" (HaV Dnr 1713-15) 9. "Multifunktionsburar" (HaV Dnr 1712-15) Projekten genomfördes genom att förslag togs fram gemensamt av SLU-Aqua och näringen utifrån fiskets uttryckliga behov och idéer. Projektförslagen prioriterades och beslutades av en särskild styrgrupp på Havs- och vattenmyndigheten (HaV), varefter SLU-Aqua upphandlade utförare och agerade projektledare. Vinnande part ansvarade sedan för att anskaffa och utveckla respektive projektidé enligt projektplanen med stöd från sekretariatet. Projekten avslutades genom en vetenskaplig utvärdering där personal från SLUAqua deltog i ett experimentellt fiske där det nyutvecklade redskapets fångstegenskaper dokumenterades och analyserades under kommersiella fiskeförhållanden.

Marine recreational fishing (MRF) is a high‐participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished, expenditures, and catches of two widely targeted species were synthesized to provide European estimates of MRF and placed in the global context. Uncertainty assessment was not possible due to incomplete knowledge of error distributions; instead, a semi‐quantitative bias assessment was made. There were an estimated 8.7 million European recreational sea fishers corresponding to a participation rate of 1.6%. An estimated 77.6 million days were fished, and expenditure was €5.9 billion annually. There were higher participation, numbers of fishers, days fished and expenditure in the Atlantic than the Mediterranean, but the Mediterranean estimates were generally less robust. Comparisons with other regions showed that European MRF participation rates and expenditure were in the mid‐range, with higher participation in Oceania and the United States, higher expenditure in the United States, and lower participation and expenditure in South America and Africa. For both northern European sea bass (Dicentrarchus labrax, Moronidae) and western Baltic cod (Gadus morhua, Gadidae) stocks, MRF represented 27% of the total removals. This study highlights the importance of MRF and the need for bespoke, regular and statistically sound data collection to underpin European fisheries management. Solutions are proposed for future MRF data collection in Europe and other regions to support sustainable fisheries management.
