In order to examine the effects of crude oil and dispersed crude oil (DCO) on the swimming ability of puffer fish, Takifugu rubripes, the critical swimming speeds (U crit) of fish exposed to different concentrations of water-soluble fraction (WSF) of crude oil and DCO solution were determined in a swimming flume. WSF and DCO significantly affected the U crit of puffer fish (p < 0.05). The U crit of puffer fish exposed to 136 mg L(-1) WSF and 56.4 mg L(-1) DCO decreased 48.7 % and 43.4 %, respectively. DCO was more toxic to puffer fish than WSF. These results suggested that crude oil and chemically dispersed oil could weaken the swimming ability of puffer fish.
为研究原油及分散原油（DCO）对红鳍东方鲀游泳能力的影响，在游泳水槽中测定了暴露于不同浓度原油水溶性组分（WSF）及DCO溶液的红鳍东方鲀的临界游泳速度（U crit）。WSF和DCO对红鳍东方鲀的U crit有显著影响（p < 0.05）。暴露于136 mg L(-1) WSF和56.4 mg L(-1) DCO的红鳍东方鲀的U crit分别下降了48.7%和43.4%。DCO对红鳍东方鲀的毒性比WSF更大。这些结果表明，原油和化学分散油会削弱红鳍东方鲀的游泳能力。
