  abstract = {{S}outh {P}acific jack mackerel, {T}rachurus murphyi, has an ocean-scale distribution, from the {S}outh {A}merican coastline to {N}ew {Z}ealand and {T}asmania. {T}his fish, captured by {H}umans since the {H}olocene, is nowadays heavily exploited and its population has decreased substantially since the mid-1990s. {T}he uncertainty associated to jack mackerel population structure currently hampers management. {S}everal hypotheses have been proposed from a single population up to several discrete populations. {S}till no.definitive answer was given. {D}etermining how environmental conditions drive jack mackerel distribution can provide insights on its population structure. {T}o do so, here we performed in three steps. {F}irst, we used satellite data to develop a statistical model of jack mackerel horizontal habitat suitability. {M}odel predictions based on interaction between temperature and chlorophyll-a match the observed jack mackerel distribution, even during extreme {E}l {N}ino event. {S}econd, we studied the impact of oxygen and show that jack mackerel distribution and abundance is correlated to oxygen over a wide variety of scales and avoid low oxygen areas and periods. {T}hird, on the basis of the above we built a conceptual 3{D} model of jack mackerel habitat in the {S}outheastern {P}acific. {W}e reveal the presence of a low suitable habitat along the {C}hilean and {P}eruvian coast, figuratively presenting a closed door caused by a gap in the horizontal habitat at 19-22 {S} and a shallow oxycline off south-centre {P}eru. {T}his kind of situation likely occurs on a seasonal basis, in austral summer but also at longer temporal scales. {A} lack of exchanges at some periods/seasons partially isolate jack mackerel distributed off {P}eru. {O}n the other hand the continuity in the habitat during most of the year explains why exchanges occur. {W}e conclude that the more likely population structure for jack mackerel is a pelagic metapopulation.},
