Decades of overfishing has driven some fish populations so low that the possibility of recovery, if even possible, would be long-term. Following the depletion of large pelagic predator and demersal fish stocks during the 1950–1960s, the main fishery was targetted on small and medium pelagics that declined abruptly to ∼200 kton (kton = 103 t) at 1989–1991 after a highly productive (∼750 kton) but overfished state in the 1980s. For Turkey, only the low cost anchovy fishery was able to maintain at the mean catch size of 368 ± 74 kton for 1992–2006 that however represented roughly twice of the maximum sustainable catch. They show that poorly understood fisheries are in much worse shape than relatively well-studied fisheries, and that the vast majority of fisheries are deteriorating. Copyright © 2011 Elsevier Ltd.
