  abstract = {{A}s top predators of pelagic food webs, large fish naturally bioaccumulate mercury ({H}g). {D}etermining {H}g burdens in commercialized fish is essential considering the concern about effects of contaminants on human health and the legal thresholds that are therefore set for local consumption and/or exportation. {T}otal {H}g levels were measured in the muscular tissue of 183 fish of five commercially important species from the tropical zone of the {W}estern {I}ndian {O}cean. {A}ll individuals were measured and sexed in order to study the impregnation of {H}g with size and sex within each species. {V}alues of {H}g found in this part of the {I}ndian {O}cean were comparable to {H}g in muscular tissue of the same species studied in other areas. {T}he highest {H}g levels were noted in {S}wordfish ({X}iphias gladius) caught in waters surrounding {R}eunion {I}sland (3.97 +/- 2.67 mu g g(-1) dry weight). {F}ollowing the {S}wordfish, in decreasing order of {H}g content, were the {Y}ellowfin {T}una ({T}hunnus albacares) and the {S}kipjack ({K}atsuwonus pelamis), then the {C}ommon {D}olphinfish ({C}oryphaena hippurus) and the {W}ahoo ({A}canthocybium solandri). {I}n the {N}orth of the {M}ozambique {C}hannel, {S}wordfish had higher {H}g levels than {Y}ellowfin {T}unas, and {D}olphinfish exhibited intermediate {H}g levels. {T}he size of a fish was a determining factor of its {H}g burden, as was the species. {D}ifferences in size-normalized {H}g levels were observed between the two study zones for {S}wordfish and {C}ommon {D}olphinfish. {S}ex, in contrast, did not influence {H}g levels suggesting that females and males have similar feeding habits. {T}he muscular {H}g levels presented here suggest that consumers of fish originating from the {W}estern {I}ndian {O}cean should limit themselves to one {S}wordfish based meal per week, or one fish meal a day if they choose to eat tuna or {C}ommon {D}olphinfish.
