Lower levels of oxygen in water could lead to a higher ratio of male fish which might threaten certain fish species with extinction, according to a study result announced Wednesday by the City University of Hong Kong.
Professor of the university's Biology and Chemistry department Rudolf Wu, said a recent discovery showed that oxygen depletion, or hypoxia as it is known, could lead to more male fish and an imbalance in the sex ratio. from www.chinaview.cn
香港城市大学的生物学与化学系教授 Rudolf Wu 在最近的一项研究中发现，当水中氧气的含量过低时，可导致雄性鱼增加，从而导致鱼的性别比失衡，可能会引起一些鱼类灭绝。
According to Professor Wu, hypoxia can inhibit the activities of certain genes that control the production of sex hormones and sexual differentiation in embryonic zebra fish.
根据Wu教授的研究，低氧可压制斑马鱼胚胎中那些控制性激素分泌和性差异的基因的活动。
