  23. SOLUTIONS Managing Fisheries Fishery Regulations Bycatch Set catch limits well below the maximum sustainable yield Use wide-meshed nets to allow escape of smaller fish Use net escape devices for seabirds and sea turtles Improve monitoring and enforcement of regulations Ban throwing edible and marketable fish back into the sea Economic Approaches Sharply reduce or eliminate fishing subsidies Aquaculture Charge fees for harvesting fish and shellfish from publicly owned offshore waters Restrict coastal locations for fish farms Control pollution more strictly Protect Areas Depend more on herbivorous fish species Certify sustainable fisheries Establish no-fishing areas Nonnative Invasions Establish more marine protected areas Kill organisms in ship ballast water Rely more on integrated coastal management Filter organisms from ship ballast water Consumer Information Label sustainably harvested fish Dump ballast water far at sea and replace with deep- sea water Publicize overfished and threatened species Fig. 11-12, p. 265
