Rashid Sumaila Published online: 18 August 2010 © Springer Science+Business Media, LLC. 2010 Abstract Excess fishing capacity and the growth in global demand for fishery products have made overfishing ubiquitous in the world’s oceans. Here we describe the potential catch losses due to unsustainable fishing in all countries’ exclusive eco- nomic zones (EEZs) and on the high seas over 1950–2004. To do so, we relied upon catch and price statistics from the Sea Around Us Project as well as an empirical rela- tionship we derived from species stock assessments by the U.S. National Oceanic and Atmospheric Administration. In 2000 alone, estimated global catch losses amounted to 7–36% of the actual tonnage landed that year, resulting in a landed value loss of between $6.4 and 36 billion (in 2004 constant US$). From 1950–2004, 36–53% of commercial species in 55–66% of EEZs may have been overfished. Referring to a species-level database of intrinsic vulnerability (V) based on life-history traits, it appears that susceptible species were depleted quickly and serially, with the aver- age V of potential catch losses declining at a similar rate to that of actual landings.
