"WASHINGTON (AP) -- Scientists call the growing oxygen-starved patches of world waterways "dead zones." That also could describe the not-so-swinging mating scene for some of the fish that live there.

For zebrafish, low oxygen levels in the water turn their habitat into the equivalent of a freshwater locker room. When oxygen is reduced, newly born male zebrafish outnumber females 3-to-1, and the precious few females have testosterone levels about twice as high as normal, according to a scientific study released Wednesday."

You mean those Oxygen bars that were popular years ago may actually be a good thing?
