  abstract = {{D}iversity in the by-catch communities from the pelagic ecosystem in the tropical tuna purse seine fishery has been poorly studied. {T}his study uses different biodiversity measures to compare drifting fish aggregating devices ({FAD}s) and {F}ree {S}chool sets (sets made on schools of tuna) of the {W}estern {I}ndian {O}cean. {D}ata was collected from observer programs carried out by the {E}uropean {U}nion between 2003 and 2010 on board {S}panish and {F}rench fleets. {A}lpha (species diversity of a particular area) and {B}eta diversity (difference in species composition between different areas) was analyzed to assess differences in the number of species, abundances and the species composition between areas and fishing modes. {G}eneralized additive models were undertaken to explore which geographical/environmental variables explain the distribution of species richness index and {S}hannon diversity index in both fishing modes. {R}esults showed that by-catch species in {FAD} communities may be used as observatories of surface pelagic biodiversity in combination with {F}ree {S}chool communities. {FAD} communities were more diverse with higher number of species (74 species) and evenly distributed than {F}ree {S}chool communities (56 species). {H}owever, environmental variables played a more important role in {F}ree {S}chool communities. {S}omalia area and {M}ozambique {C}hannel were the areas with highest biodiversity rates in both fishing modes. {T}his work contributed for the future implementation of the {EAFM} to manage the pelagic ecosystem in a holistic and more integrated way.},
