A marine protected area ( MPA ) is a protected area of the world's seas , oceans , estuaries or in the US, the Great Lakes . These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life . MPAs can provide economic benefits by supporting the fishing industry through the revival of fish stocks, as well as job creation and other market benefits via ecotourism . The value of MPA to mobile species is unknown.
71-670: Adelaide Dolphin Sanctuary ( ADS ) is a marine protected area in the Australian state of South Australia located on the east coast of Gulf St Vincent in and adjoining the north-western part of Adelaide , covering the estuary of the Port River around Port Adelaide and northwards past St Kilda . It was established in 2005 for the protection of a resident population of Indo-Pacific bottlenose dolphins ( Tursiops aduncus ). The dolphins are keenly watched by dolphin enthusiasts, as well as being
142-747: A cetacean sanctuary in the Ligurian Sea named the Pelagos Sanctuary for Mediterranean Marine Mammals . This sanctuary includes both national and international waters. Both the CBD and IUCN recommended a variety of management systems for use in a protected area system. They advocated that MPAs be seen as one of many "nodes" in a network of protected areas. The following are the most common management systems: Seasonal and temporary management —Activities, most critically fishing, are restricted seasonally or temporarily, e.g., to protect spawning/nursing grounds or to let

The degree to which environmental regulations affect shipping varies according to whether MPAs are located in territorial waters , exclusive economic zones , or the high seas . The law of the sea regulates these limits. Most MPAs have been located in territorial waters, where the appropriate government can enforce them. However, MPAs have been established in exclusive economic zones and in international waters . For example, Italy, France and Monaco in 1999 jointly established

The most important sections get the highest protection, such as a no take zone and are surrounded with areas of lesser protections. Multiple-use MPAs can make use of very diverse fisheries regulations to balance fisheries extraction with nature protection. Community involvement and related approaches —Community-managed MPAs empower local communities to operate partially or completely independent of

Dolphin expert Mike Bossley AM lobbied for the sanctuary from the mid-1990s, becoming interested after reading about a dolphin that swam along next to racehorses being exercised in the water off West Beach , further down the coast. The dolphins in the area are Indo-Pacific bottlenose dolphins. The sanctuary

Related terms include; specially protected area (SPA), Special Area of Conservation (SAC), the United Kingdom's marine conservation zones (MCZs), or area of special conservation (ASC) etc. which each provide specific restrictions. Stressors that affect oceans include the impact of extractive industries , marine pollution , and changes to the ocean's chemistry ( ocean acidification ) resulting from elevated carbon dioxide levels, due to our greenhouse gas emissions (see also effects of climate change on oceans ).

A 2018 study by Mike Rossley et al. suggested: Social learning is the most likely mechanism for the introduction and spread of this unusual behaviour, which has no known adaptive function.

Approximately 64% of the world's oceans are " international waters " and subject to regulations such as the Law of the Sea and the governance of UN bodies such as the International Seabed Authority . The remaining 36% of the ocean is under the governance of individual countries within their Exclusive Economic Zones (EEZs). Some individual national EEZ's cover very large areas , such as France and USA (>11 million km ), and Australia, Russia, UK, and Indonesia (>6 million km ). Some states have very small land areas but extremely large EEZ's such as Kiribati,

United States Executive Order 13158 in May 2000 established MPAs, defining them as: Any area of the marine environment that has been reserved by federal, state, tribal, territorial, or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein. The Convention on Biological Diversity defined the broader term of marine and coastal protected area (MCPA): Any defined area within or adjacent to

This area is equivalent to 27 million square kilometres, equivalent to the land areas of Russia and Canada combined, although some argue that the effective conservation zones (ones with the strictest regulations) occupy only 5% of the ocean area (about equivalent to the land area of Russia alone). Marine conservation zones, as with their terrestrial equivalents, vary in terms of rules and regulations. Few zones rule out completely any sort of human activity within their area, as activities such as fishing, tourism, and transport of essential goods and services by ship, are part of

Empowering communities to manage resources can lower conflict levels and enlist the support of diverse groups that rely on the resource such as subsistence and commercial fishers, scientists, recreation, tourism businesses, youths and others.
