The potential for blue growth in marine fish yield, profit and abundance of fish in the ocean

摘要: The oceans provide food, employment and income for billions of people. We analyzed data from scientific stock assessments, a statistical model other fish stocks, to summarize the past present status, potential catch, abundance profit 4713 stocks constituting 78% global fisheries. Three major scenarios future trends are considered; business as usual (BAU) in which largely unmanaged fisheries move towards bioeconomic equilibrium but where well-managed maintain their management, maximum sustainable yield (MSY) managed maximize yield, reform (REF) competitive race is eliminated profit. prospects differ greatly based on region world product type. This analysis forecasts that tuna forage species will remain roughly same current levels under all three scenarios, while there does appear be increased whitefish. There considerable room most these better management. Increased come rebuilding overexploited reducing fishing mortality still abundant fished at high rates, surprisingly some harder. Indeed Europe North America primary comes fully exploiting now lightly exploited. Asia provides greatest opportunity by would lead reduced pressure.
