Global marine fisheries with economic growth

This study explores the state of global marine fisheries and empirically analyzes its relationship to economic factors. We apply the pooled mean group estimator method to examine 70 fishing countries for the period of 1961-2010. We use both catch and the estimated size of stock as proxies for marine ecosystems. Our results confirm that economic growth initially leads to the deterioration of marine ecosystems. However, for a per capita income level of approximately 3,827 USD for the catch model and of 6,066 USD for the biomass model, we found beneficial impacts of economic growth on the sustainability of marine fisheries. Over the next two decades, we expect to see a decline in catch and indications of stock recovery.
