Reducing the Fuel Use Intensity of Fisheries: Through Efficient Fishing Techniques and Recovered Fish Stocks

Understanding the drivers of greenhouse gas emissions in food production systems is becoming urgent. For wild capture fisheries, fuel use during fishing phase generally dominates and highly variable between fisheries. Fuel also essential for economy but fuel-intensive fisheries can still be profitable due to subsidies, particular, if target species high value. Developing an innovative bottom-up approach based on detailed catch spatial effort data, absence direct we analysed intensity (fuel per kg landed) economic efficiency (landing value litre used) Danish period 2005-2019. An overall decline did not significantly affect efficiency, which was stable most fleet segments marine species. Robust differences among individual reflected differential accessibility vulnerability fishing. In addition, different techniques targeting same set showed unit landed. seining gillnets had a lower higher than demersal trawling; purse pelagic trawling. The variability stocks fleets indicates that there potential improvement from improved stock status. Short-term management actions promote best available fuel-efficient combined with additional long-term secure recovery have reduce fishery emissions. Sustainable normative environmental are crucial developing incentives towards reducing whenever sector industry science work jointly at implementing solutions, as limited long activity profitable.
