On 20 April 2010 the Deepwater Horizon oil drilling rig was destroyed by an explosion and fire, and the oil well began releasing oil into the Gulf of Mexico. The oil spill caused significant economic harm to the Gulf fishing industry because of fishery closures and consumer concerns related to the safety of Gulf seafood. Intermediate and long-term concerns are related to impacts on marine populations and degradation of fisheries habitat necessary for spawning, development of early life stages and growth. This book presents information related to damages caused by the oil spill to Gulf fisheries and wildlife and efforts to mitigate these damages. Many uncertainties exist because of the complexity and scale of Gulf fisheries and ecosystems that have been affected by the oil spill. Direct and indirect damages to fisheries and the Gulf environment are still being assessed and these efforts are likely to continue for years to come.
