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.
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. Such a discrepancy would have a dramatic impact on the reproductive success of certain fish, and could mean population decline and possible extinction.
This is the first ever report in the world of science that suggests hypoxia can affect the sex development, sex differentiation and sex ratio in an animal, and the result has been published in an international academic journal "Environmental Science and Technology."

一個(gè)最新的發(fā)現(xiàn)表明，氧氣的消耗或者氧氣不足，可能會(huì)導(dǎo)致雄魚數(shù)量多余雌性，并造成性別比例的失衡。這個(gè)失衡會(huì)直接影響某些魚種的成功繁殖，引起數(shù)量的減少，并可能消失。
這是科學(xué)界首次報(bào)道在動(dòng)物中，氧氣不足會(huì)影響性別的發(fā)展，性別的差異和性別的比例失衡。該研究結(jié)果已經(jīng)被一國(guó)際學(xué)術(shù)雜志“環(huán)境科學(xué)技術(shù)”發(fā)表。
