  abstract = {{M}ercury, omega-3 (docosahexaenoic acid, {DHA} and eicosapentaenoic acid, {EPA}) and macronutrients (fat and proteins) were quantified on a wet weight (ww) basis in 20 species of fish taken as bycatch in tropical tuna fisheries. {B}ased on a hazard quotient taking into account mercury and omega-3 contents, a benefit-risk assessment for the consumption of these pelagic species was conducted for three people categories: young children, children and adults. {A}ll fish bycatch were found to be an excellent source of proteins (min -max = 14.4-25.2 g/100 g fillet), had low omega-6/omega-3 ratios (<1, except for silky shark), and had mercury content below the safety limits defined by sanitary agencies. {S}ilky shark and {I}stiophoridae had the highest mercury contents (min -max = 0.029-0.317 ppm ww). {O}mega-3 contents were the lowest in silky shark (0.2 0.2 mg/100 g fillet) and the highest in striped marlin (3.6 +/- 3.2 g/ 100 g fillet). {B}illfishes ({I}stiophoridae, including striped marlin), minor tunas ({S}combridae), and {C}arangidae had the highest omega-3 contents (min -max = 0.68-7.28 g/100 g fillet). {T}he highest hazard quotient values obtained for silky shark and great barracuda reflected a lower nutritional benefit (i.e., low omega-3 source) than risk (i.e., mercury exposure), making them not advisable for consumption. {E}ight species had low hazard quotients, and among them cottonmouth jack and flat needlefish were found of high health interest (high protein, moderate fat contents, and low omega-6/omega-3 ratio). {A} daily serving portion of 85-200 g (according to people category) can be recommended for these species. {B}atfish, and to a lower extent pompano dolphinfish and brassy chub, can also be consumed safely and would provide greater health benefits than risks. {T}hese results advocate for a better access of these species to local populations.},
