Jellyfish threaten to 'dominate' oceans http://apocadocs.com/s.pl?1244483387
Giant jelly fish are taking over parts of the world's oceans due to overfishing and other human activities, say researchers... Jellyfish are normally kept in check by fish, which eat small jellyfish and compete for jellyfish food such as zooplankton...
But, with overfishing, jellyfish numbers are increasing. Jellyfish feed on fish eggs and larvae, further impacting on fish numbers.
To add insult to injury, nitrogen and phosphorous in run-off cause red phytoplankton blooms, which create low-oxygen dead zones where jellyfish survive, but fish can't.
