  abstract = {{F}ishing on floating objects ({FOB}s) dominates catch in tropical tuna purse seine fisheries. {O}ne frequently cited advantage of deploying {GPS}-monitored {FOB}s is that the position information can be used for directed fishing to reduce search time for tuna. {H}owever, purse seiners also fish on foreign objects for which position information is not available. {I}t is critical to quantify the prevalence of fishing on {GPS}-monitored versus unmonitored {FOB}s to understand how they impact fishing effort and catch per unit effort. {W}e analyzed {F}rench commercial, observer, and {FOB} trajectory data in the {A}tlantic and {I}ndian oceans to determine how often purse seine vessels fish on {GPS}-monitored {FOB}s. {O}nly 2.7%-20.4% of {F}rench {FOB} fishing sets over 2007-2013 in both oceans were made on {GPS}-monitored {FOB}s. {T}hough increasing over time, the low percentage suggests that {F}rench vessels do not primarily use {GPS}-monitored {FOB}s to reduce search time for tuna. {W}e hypothesize that fishery-wide {FOB} deployments have important collective consequences for overall fishing effort and recommend that future effort metrics should be based on fishery-wide {FOB} activities.},
