Conservation Status
The whale shark is targeted by commercial fisheries in several areas where they seasonally aggregate. The population is unknown and the species is considered vulnerable by the IUCN. It is listed, along with 6 other species of shark, under the CMS Memorandum of Understanding (MoU) on the Conservation of Migratory Sharks. In 1998, the Philippines banned all fishing, selling, importing and exporting of whale sharks for commercial purposes, followed by India in May 2001, and Taiwan in May 2007. They are currently listed as a vulnerable species; however, they continue to be hunted in parts of Asia, such as Taiwan and the Philippines.
In 2006, Resorts World Sentosa announced its plans to bring in whale sharks for their marine life park. This was met with opposition from seven notable conservation societies. In 2009, the plan was shelved in favour of a search for other alternatives.
In 2010, the Gulf of Mexico oil spill resulted in 4,900,000 barrels (780,000 m3) of oil flowing into an area south of the Mississippi River Delta, where one-third of all whale shark sightings in the northern part of the gulf have occurred in recent years. Sightings confirmed that the whale sharks were unable to avoid the oil slick which was situated on the surface of the sea where the whale sharks feed for several hours at a time. No dead whale sharks have been found however.

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)
“Knowing how beleaguered working mothers truly are—knowing because I am one of them—I am still amazed at how one need only say “I work” to be forgiven all expectation, to be assigned almost a handicapped status that no decent human being would burden further with demands. “I work” has become the universally accepted excuse, invoked as an all-purpose explanation for bowing out, not participating, letting others down, or otherwise behaving inexcusably.”
—Melinda M. Marshall (20th century)
