Mercury concentrations in Pacific hake increase with fish size and with the latitude of collection. While the mercury-size trend is consistent with data for other species, the latitudinal trend is opposite to that reported for other fishes over the same geographical area. Consequently, latitudinal trends of mercury concentrations in fishes do not necessarily indicate trends of mercury concentrations in water. Food habits and metabolism may cause the observed variations.
太平洋无须鳕体内的汞含量随鱼体大小和采集地点的纬度升高而增加。虽然汞含量与鱼体大小的关系趋势与其他物种的数据一致，但纬度趋势与在相同地理区域内其他鱼类的报告情况相反。因此，鱼类体内汞含量的纬度趋势不一定表明水中汞含量的趋势。饮食习惯和新陈代谢可能导致了观察到的差异。
