Bottom-trawling makes for skinny cod http://apocadocs.com/s.pl?1299769950
Trawling the sea floor for bottom-dwelling fish is making cod skinnier, scientists have found. The study looked at the size of cod, lemon sole, megrim and haddock in the Celtic Sea south of Ireland.
It found these fish tended to be smaller in heavily trawled areas and in worse general health....
Writing in the journal, Proceedings of the Royal Society B, they warned that the study "implies that bottom trawling can reduce habitat-carrying capacity".
The practice "is likely to further diminish fisheries productivity and impair the recovery of threatened stocks and ecosystems."

What kinda thing is "habitat carrying capacity"? It's too hard to say.
