The International Fisheries Innovation Network (I-FIN) is a collaborative of scientists and managers working to improve the performance of fisheries and their contribution to food security.  This session will summarize the results of several efforts undertaken by members of I-FIN in evaluating the status of stocks, the relationship between how fisheries are managed and the outcomes,  the impacts of bottom trawling on benthic ecosystems, and the impact of fishing forage fish on their predators.  We will show that in many places fishing pressure has been reduced and stocks are increasing.  In other places where fishing pressure remains high stocks remain at low abundance.  We suggest that for the parts of the world where abundance data are not readily available the stock status is generally poor.  There is a close relationship between the intensity of fisheries management, particularly enforcement of regulations and the abundance of fish stocks.  We show detailed mapping of the impact of bottom trawling and great differences in different parts of the world.  Fishing forage fish also has quite variable impacts on their predators, but the overall impacts in systems we have studied are much less than commonly assumed.
