Conservation Status
Over tens of thousands of spinner dolphins, mostly eastern and white-bellied varieties, were killed in the thirty years after purse seine fishing for tuna was introduced in the 1950s. The process killed probably half of all Eastern Spinner Dolphins. See Pantropical spotted dolphin for a discussion. They have also been contaminated by pollutants such as DDT and PCBs. Spinner dolphins, as with other species impacted by the ETP tuna purse-seine fishery are managed both nationally by the coastal countries and internationally by the IATTC. The IATTC has imposed annual stock mortality limits on each purse seine and promulgated regulations regarding the safe release of dolphins. Spinner dolphins in Hawaii have multiple daily visits to their nearshore resting grounds. The Big Island, Hawaii on the Kona Coast is a popular area for Spinner Dolphins. Boats take people out daily to snorkel and interact with the local dolphin population.
The eastern tropical Pacific and Southeast Asian populations of the Spinner dolphin are listed on Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), since they have an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements.
In addition, the Spinner dolphin is covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MoU) and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia (Western African Aquatic Mammals MoU).

Famous quotes containing the words conservation and/or status:
“A country grows in history not only because of the heroism of its troops on the field of battle, it grows also when it turns to justice and to right for the conservation of its interests.”
—Aristide Briand (1862–1932)
“Anthropologists have found that around the world whatever is considered “men’s work” is almost universally given higher status than “women’s work.” If in one culture it is men who build houses and women who make baskets, then that culture will see house-building as more important. In another culture, perhaps right next door, the reverse may be true, and basket- weaving will have higher social status than house-building.”
—Mary Stewart Van Leeuwen. Excerpted from, Gender Grace: Love, Work, and Parenting in a Changing World (1990)
