  abstract = {{T}he little information available on fuel consumption and emissions by high seas tuna fisheries indicates that the global tuna fleet may have consumed about 2.5 {M}t of fuel in 2009, resulting in the production of about 9 {M}t of {CO}2-equivalent greenhouse gases ({GHG}s), i.e., about 4.5-5% of the global fishing fleet emissions. {W}e developed a model of annual fuel consumption for the large-scale purse seiners operating in the western {I}ndian {O}cean as a function of fishing effort, strategy, and vessel characteristics based on an original and unique data set of more than 4300 bunkering operations that spanned the period 2013-2019. {W}e used the model to estimate the total fuel consumption and associated {GHG} and {SO}2 emissions of the {I}ndian {O}cean purse seine fishery between 1981 and 2019. {O}ur results showed that the energetic performance of this fishery was characterized by strong interannual variability over the last four decades. {T}his resulted from a combination of variations in tuna abundance but also changes in catchability and fishing strategy. {I}n recent years, the increased targeting of schools associated with fish aggregating devices in response to market incentives combined with the {IOTC} management measure implemented to rebuild the stock of yellowfin tuna has strongly modified the productivity and spatio-temporal patterns of purse seine fishing. {T}his had effects on fuel consumption and air pollutant emissions. {O}ver the period 2015 to 2019, the purse seine fishery, including its support vessel component, annually consumed about 160,000 t of fuel and emitted 590,000 t of {CO}2-eq {GHG}. {F}urthermore, our results showed that air pollutant emissions can be significantly reduced when limits in fuel composition are imposed. {I}n 2015, {SO}2 air pollution exceeded 1500 t, but successive implementation of sulphur limits in the {I}ndian {O}cean purse seine fishery in 2016 and 2018 have almost eliminated this pollution. {O}ur findings highlight the need for a routine monitoring of fuel consumption with standardized methods to better assess the determinants of fuel consumption in fisheries and the air pollutants they emit in the atmosphere.},
