Congrats!!! NOAA discovered fisheries ecology. Here it comes (From NOAA's Fish News digest):
National – Trio of Factors Drive Marine Fisheries Production in Northern Hemisphere Ecosystems Comparisons of marine fisheries in thirteen northern hemisphere ecosystems reveal that a trio of factors— fishing, food web/predator-prey interactions, and environmental conditions—drive marine fisheries production. Better understanding of the relative influence of this triad of drivers on fish populations can make fishery management more effective, as well as improve overall understanding of how fisheries work within an ecosystem. Ten studies, published online July 12 in Marine Ecology Progress Series, identify trends and common patterns governing fisheries productivity in northern hemisphere temperate marine ecosystems. The studies resulted from two international workshops in 2010 and 2011 in Woods Hole, Mass. organized and hosted by NOAA’s Northeast Fisheries Science Center.

WOW!!! Not just overfishing! Also environmental conditions (that involve not mentioned here pollution and habitat destruction). Predator-prey interactions... ho, ho! This would comprise also the all-protected marine mammals (each seal 4-6 kg of fish/day; each dolphin - 5-7 kg/day, killer wales... well, well...). Does it mean less fishermen flogging? Anyway, BRAVO, CHEERS, MAZAL TOV, SALUTI to NOAA.

Overfishing? sometimes...
What I'm now focusing on is the effect of aquatic pollution and its separate components on fish populations, as a factor in their impoverishment. See the case of the dredging in the port of Gladstone QSL, Australia, and the associated mortalities of marine life.
This is one of the subjects that are cautiously and circuitously avoided, if not totally ignored by management establishments and most NGOs; why to annoy petro-chemical interests when they've got fishermen to bash… Well, see who's financing them.
