The importance of eating habits and the number of fish sampled in the estimation of mercury environmental contamination through biological indicators was studied. The species used were one with piscivorous habits (Anguilla anguilla) and another with omnivorous habits (Ciprinus carpio). From one original sample for each species, randomized samples were generated using the subroutine GGSRS from the mathematics library IMSL, and later the statistical significance of Pearson's correlation coefficient for the relationship between fish weight and mercury concentrations in muscle was obtained for each random sample. The results show that the use of omnivorous species such as Ciprinus carpio as a biological indicator of contamination enables us to carry out estimations with a greater degree of confidence than when piscivorous species such as Anguilla anguilla are used.
研究了饮食习惯的重要性以及在通过生物指标估算汞环境污染时采样的鱼类数量。所用的物种为一种肉食性（鳗鲡）和另一种杂食性（鲤鱼）。对于每一种鱼类，从原始样本中随机生成了亚样本，使用数学库 IMSL 中的子例程 GGSRS，然后获得了每个随机样本中鱼体重与肌肉中汞浓度之间的皮尔逊相关系数的统计显著性。结果表明，使用杂食性鱼类（如鲤鱼）作为污染的生物指标，比使用肉食性鱼类（如鳗鲡）进行估计更有信心。
