Once it had been noticed what enormous numbers of dolphins were being killed in tuna fisheries in the eastern Pacific, actions were implemented to try and reduce these unnecessary deaths. In the 1970s, the United States employed laws and measures aiming to reduce dolphin bycatch to levels approaching zero through improved fishing methods (6). In 1979, the Inter-American Tropical Tuna Commission began a dolphin conservation program, and soon, the idea of dolphin-safe tuna became popular, with the United States only allowing the sale of dolphin-safe tuna by 1994. In 1999, the International Dolphin Conservation Program Agreement came into force, which meant the major tuna fishing countries in the eastern Pacific were bound to certain measures such as having observers on boats and strict dolphin-mortality limits. As a result of all of these actions, dolphin mortality has fallen drastically (6), which will hopefully give the pantropical spotted dolphins, and other dolphin species, a much needed opportunity to recover.
