No doubt someone will call bullshit unless I supply a peer reviewed scientific document to back up what I just said.

Here you go:

Cohen,A.N.1998.Ships 'Ballast Water and the Introduction of Exotic Organisms into the San Francisco Estuary:

http://www.waterboards.ca.gov/water_...cydocs/178.pdf

San Francisco Estuary Institute, 1325 South 46th Street, Richmond CA 94804 (510-231-9539).

That's mostly about San Francisco Bay but in it's history section it discusses catastrophic fishery destruction in the Baltic and other areas due to overpopulation of invasive Jellyfish brought in by bilge water. Just glancing through it it's interesting to note that after 30 years comb jellyfish populations in the Baltic are finally on the decline mainly due to another invasive species, another jellyfish that feeds on larva comb jellyfish, that was (you guessed it) brought in from another part of the world by commercial ships in their bilge water.

The publication is a few years old but they do not say anything about whether or not the destroyed Baltic fisheries have started to, or if they possibly could ever recover.
