The collapse of many shark populations in the North Atlantic due to overfishing has led to increase in the number of some skates and rays, species that were typical prey of sharks such as the great white or the hammerhead, this has had significant consequences on fishing communities, as the increased number of skates and rays have affected commercial fisheries for bay scallops and other shellfish (Myers, 2007). At an international level, the World Bank/FAO Rent Drain study estimates that approximately USD 50 billion is lost annually in global resource rent from fisheries as a result of poor governance (World Bank/FAO, 2008). Of course, the figures should also be weighed against the costs of undertaking rebuilding programs and subsequent management of the stocks. Even if a stock is rebuilt, fishing may not yield the same level of pre-collapse revenues, as there may be a lag (especially for a smaller fishery) to re-establish itself and therefore regain access to markets.
