Seismic surveys are used to locate oil and gas reserves below the seabed and can be a major source of noise in marine environments. Their effects on commercial fisheries are a subject of debate, with experimental studies often producing results that are difficult to interpret. We overcame these issues in a large-scale experiment that quantified the impacts of exposure to a commercial seismic source on an assemblage of tropical demersal fishes targeted by commercial fisheries on the North West Shelf of Western Australia. We show that there were no short-term (days) or long-term (months) effects of exposure on the composition, abundance, size structure, behavior, or movement of this fauna. These multiple lines of evidence suggest that seismic surveys have little impact on demersal fishes in this environment.
地震调查用于定位海底以下的石油和天然气储量，它们可能是海洋环境中主要的噪声源。它们对商业渔业的影响是一个有争议的话题，实验研究通常产生难以解释的结果。我们在一项大规模实验中克服了这些问题，该实验量化了暴露于商业震源对商业渔业在西澳大利亚西北部西北大陆架捕捞的热带底层鱼类组合的影响。我们表明，暴露对该动物群的组成、丰度、大小结构、行为或运动没有短期（数天）或长期（数月）的影响。这些多重证据表明，地震调查对这种环境中的底层鱼类几乎没有影响。
