ECOLOGICAL REPERCUSSIONS OF HISTORICAL FISH EXTRACTION FROM THE SOUTHERN OCEAN
Abstract: A major mid-1980s shift in ecological structure of significant portions of the Southern ... Ocean was partially due to the serial depletion of fish by intensive industrial fishing, rather than ... strong year classes, as is true of such fish elsewhere. A climate regime, the Southern Annular Mode, once ... oscillated between two states, but has remained in its “positive mode” since the time of the fish extraction ...
