Systematic studies on the changes in concentrations of petroleum hydrocarbons (PHs) and their effects on fishery species in the Bohai Sea during 1974-2004 are presented. Changes in PHs concentrations were closely related to Yellow River runoff. Concentrations of PHs accumulated in fish and shrimp increased by about 0.712 mg/kg dry weight when trophic level of fish and shrimps increased by 1. Attention should also be paid to the high PHs concentrations in mollusks along the coastal waters of the Bohai Sea. Average concentration of PHs in the adjacent coastal waters of Tianjin City during 1996-2005 decreased the population growth rates of fish, crustaceans and mollusks in the Bohai Sea by 2.58%, 6.59% and 2.33%, respectively. Therefore, PHs have significantly contributed to the decline in fisheries in the Bohai Sea, and they must be reduced to realize the sustainable fisheries.
本文介绍了 1974-2004 年期间渤海石油烃（PHs）浓度变化及其对渔业物种的影响的系统研究。PHs 浓度的变化与黄河径流量密切相关。当鱼类和虾类的营养级增加 1 级时，其体内 PHs 浓度增加约 0.712mg/kg 干重。还应注意渤海沿海水域贝类中 PHs 的高浓度。1996-2005 年期间，天津市邻近沿海海域 PHs 的平均浓度分别使渤海鱼类、甲壳类和贝类的种群增长率降低了 2.58%、6.59%和 2.33%。因此，PHs 对渤海渔业的衰退有显著贡献，必须加以减少，以实现渔业的可持续发展。
