Hypoxia is amongst the most widespread and pressing problems in aquatic environments. Here we demonstrate that fish (Oryzias melastigma) exposed to hypoxia show reproductive impairments (retarded ...

If you want to know how climate change and hypoxia -- the related loss of oxygen in the world's oceans -- affect fish species such as the economically important Baltic cod, all you have to do is ask ...
