To balance the risks and benefits of fish consumption, selenium, fatty acids (DHA + EPA), and mercury in fishery products were determined. Analyzed products were canned tuna, frozen tuna (Thunnus albacares), smoked striped marlin (Tetrapturus audax), fresh Pacific sierra (Scomberomorus sierra), fresh dolphinfish (Coryphaena hippurus), fresh tilapia (Gerres cinereus), and fresh bullseye puffer (Sphoeroides annulatus). Mercury (μg g⁻¹ wet weight) ranged from 0.01 (dolphinfish) to 0.23 (bullseye puffer); Se ranged from 0.12 to 0.25. EPA + DHA ranged from 1.16 to 10.72 mg g⁻¹. Intake of EPA + DHA was comparable or above the recommended daily intake; Hg intake was below the reference dose but Se intake was below than recommended values for the different population groups. Considering the HBV_Se, fishery products had positive values; i.e., they are healthy food items. According to the interaction of Hg and Se and the rate of fishery product consumption, the risk for consumers is below one percent.

为了平衡鱼类消费的风险和收益，确定了渔业产品中的硒、脂肪酸（DHA + EPA）和汞。分析的产品包括金枪鱼罐头、冷冻金枪鱼 ( Thunnus albacares )、烟熏条纹马林鱼 ( Tetrapturus audax )、新鲜太平洋山脉 ( Scomberomorus sierra )、新鲜海豚鱼 ( Coryphaena hippurus )、新鲜罗非鱼 ( Gerres cinereus ) 和新鲜牛眼河豚 ( Sphoeroides annulatus ) ）。汞（μg g ^-1湿重）范围从 0.01（海豚）到 0.23（牛眼河豚）；Se 范围为 0.12 至 0.25。EPA + DHA 范围为 1.16 至 10.72 mg g ^-1. EPA + DHA 的摄入量相当于或高于建议的每日摄入量；汞摄入量低于参考剂量，但硒摄入量低于不同人群的推荐值。考虑到HBV _Se，水产品具有正值；即，它们是健康食品。根据汞和硒的相互作用以及水产品消费率，消费者面临的风险低于百分之一。
