Jellyfish 'may benefit from ecosystem instability' http://apocadocs.com/s.pl?1288621379
A team of researchers have been trying to identify how jellyfish may benefit from marine ecosystems destabilised by climate change and overfishing.
There is concern that a rise in jellyfish numbers could prevent depleted commercially important fish stocks recovering to historical levels.
However, a study by European scientists says more data is needed to understand what is happening beneath the waves.... In recent years, there have been a number of examples of sudden blooms of jellyfish in European waters - including the Irish, Mediterranean and Black seas - which have killed fish and closed beaches.
In 2007, an invasion of mauve stingers (Pelagia noctiluca) wiped out Northern Ireland's only salmon farm, killing more than 100,000 fish.... "It is quite a complicated set of possible linkages that need to be drawn, which we really only have a vague insight at the moment.
"For the recent period where we have good data, it appears as if sea surface temperature is the most important variable.
"This does not necessarily prove it of course, but it does appear to be benefiting jellyfish."

I guess "more study" is not only needed, but will be experienced.
