Spatio-temporal distribution of the principal billfish species in catches by the Ecuadorian artisanal longline fishery targeting tuna-billfish-sharks (TBS) for fishing year 2011 ‒ 2012.

<p>The area of the pies is proportional to the catch rates of the four principal billfish species (blue marlin (BUM), swordfish (SWO), stripped marlin (MLS) and Indo-Pacific sailfish (SFA)). The monthly maximum total CPUE (“Max”; in mt per 1000 hooks, rounded to the nearest whole ton) is shown in the lower-left corner of each figure.
