Save Our Seas Foundation
The Save Our Seas Foundation is a philanthropic organization committed to protecting the world’s oceans. It was founded in Geneva, Switzerland, on 23 September 2003. Focusing primarily on charismatic threatened wildlife (endangered elasmobranchs, or sharks, rays and skates) and their habitats, the Save Our Seas Foundation supports cutting-edge research, conservation and education projects worldwide. Background Approximately 400 species of sharks are found in the world. They have inhabited our oceans for more than 500 million years, pre-dating the first dinosaurs by 100 million years, and they appear in every single ocean, playing a crucial role in the health of the marine ecosystems. Due to threats such as overfishing, climate change, habitat loss and persecution, many shark populations have declined by more than 90%. Over 100 million sharks are killed annually in commercial fishing, resulting in such severe declines that more than a quarter of shark species and the ...

Philanthropy
Philanthropy is a form of altruism that consists of "private initiatives, for the public good, focusing on quality of life". Philanthropy contrasts with business initiatives, which are private initiatives for private good, focusing on material gain; and with government endeavors, which are public initiatives for public good, notably focusing on provision of public services. A person who practices philanthropy is a philanthropist. Etymology The word ''philanthropy'' comes , from ''phil''- "love, fond of" and ''anthrōpos'' "humankind, mankind". In the second century AD, Plutarch used the Greek concept of ''philanthrôpía'' to describe superior human beings. During the Middle Ages, ''philanthrôpía'' was superseded in Europe by the Christian virtue of ''charity'' (Latin: ''caritas''); selfless love, valued for salvation and escape from purgatory. Thomas Aquinas held that "the habit of charity extends not only to the love of God, but also to the love of our neighbor". Phila ...

Sustainable Fishery
A conventional idea of a sustainable fishery is that it is one that is harvested at a sustainable rate, where the fish population does not decline over time because of fishing practices. Sustainability in fisheries combines theoretical disciplines, such as the population dynamics of fisheries, with practical strategies, such as avoiding overfishing through techniques such as individual fishing quotas, curtailing destructive and illegal fishing practices by lobbying for appropriate law and policy, setting up protected areas, restoring collapsed fisheries, incorporating all externalities involved in harvesting marine ecosystems into fishery economics, educating stakeholders and the wider public, and developing independent certification programs. Some primary concerns around sustainability are that heavy fishing pressures, such as overexploitation and growth or recruitment overfishing, will result in the loss of significant potential yield; that stock structure will erode to t ...

Sustainability And Environmental Management
At the global scale sustainability and environmental management involves managing the oceans, freshwater systems, land and atmosphere, according to sustainability principles. Land use change is fundamental to the operations of the biosphere because alterations in the relative proportions of land dedicated to urbanisation, agriculture, forest, woodland, grassland and pasture have a marked effect on the global water, carbon and nitrogen biogeochemical cycles.Krebs (2001) pp. 560–582. Management of the Earth's atmosphere involves assessment of all aspects of the carbon cycle to identify opportunities to address human-induced climate change and this has become a major focus of scientific research because of the potential catastrophic effects on biodiversity and human communities. Ocean circulation patterns have a strong influence on climate and weather and, in turn, the food supply of both humans and other organisms.

Shark Finning
Shark finning is the act of removing fins from sharks and discarding the rest of the shark back into the ocean. This act is prohibited in many countries. The sharks are often still alive when discarded, but without their fins.Spiegel, J. (2000"Even Jaws deserves to keep his fins: outlawing shark finning throughout global waters" ''Boston College International and Comparative Law Review'', 24 (2): 409–438. Unable to swim effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea enables fishing vessels to increase profitability and increase the number of sharks harvested, as they must only store and transport the fins, by far the most profitable part of the shark; the shark meat is bulky to transport. Many countries have banned this practice and require the whole shark to be brought back to port before removing the fins. Shark finning increased since 1997 largely due to the increasing demand for shark fins for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red List Index
Summary of 2006 IUCN Red List categories. The ''Red List Index (RLI)'', based on the IUCN Red List of Threatened Species, is an indicator of the changing state of global biodiversity. It defines the conservation status of major species groups, and measures trends in extinction risk over time. By conducting conservation assessments at regular intervals, changes in the threat status of species in a Taxonomy (biology), taxonomic group can be used to monitor trends in extinction risk. RLIs have been calculated for birds and amphibians, using changes in threat status for species in each of the groups. As well as taxonomic groups, RLIs can show trends in extinction risk according to biogeographic realm, habitat type, and dominant threat process. Sampled approach Producing indices of change in extinction risk by comprehensively assessing whole species groups, while feasible for well studied groups with relatively few species, is not suitable for all taxonomic groups. Assessing every ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Conservation
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change. Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors ...

List Of Threatened Sharks
__NOTOC__ Threatened species, Threatened sharks are those vulnerable to Species endangerment, endangerment (extinction) in the near future. The International Union for Conservation of Nature (IUCN) is the world's oldest global environmental organization. It evaluates threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: :: Vulnerable species :: Endangered species :: Critically endangered species The term ''threatened'' strictly refers to these three categories (critically endangered, endangered and vulnerable), while ''vulnerable'' is used to refer to the least at risk of these categories. The terms can be used somewhat interchangeably, as all ''vulnerable'' species are threatened, all ''endangered'' species are vulnerable and threatened, and all ''critically endangered'' species are endangered, vulnerable and threatened. Threatened species are also referred to as a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Threatened Rays
__NOTOC__ Threatened rays are those vulnerable to endangerment (extinction) in the near future. The International Union for Conservation of Nature (IUCN) ranks threatened species in three categories: :: Vulnerable species :: Endangered species :: Critically endangered species The term ''threatened'' strictly refers to these three categories (critically endangered, endangered and vulnerable), while ''vulnerable'' is used to refer to the least at risk of these categories. The terms can be used somewhat interchangeably, as all ''vulnerable'' species are threatened, all ''endangered'' species are vulnerable and threatened, and all ''critically endangered'' species are endangered, vulnerable and threatened. Threatened species are also referred to as a red-listed species, as they are listed in the IUCN Red List of Threatened Species. Together rays and sharks make up the class of modern cartilaginous fishes. Modern fish are either cartilaginous or bony. Cartilaginous fishes have ...

List Of Sharks
Shark is the naming term of all members of Selachimorpha suborder in the subclass Elasmobranchii, in the class Chondrichthyes. The Elasmobranchii also include rays and skates; the Chondrichthyes also include Chimaeras. The first shark-like chondrichthyans appeared in the oceans 430 million years ago, developing into the crown group of sharks by the Early Jurassic. Listed below are extant species of shark. Sharks are spread across 512 described and 23 undescribed species in eight orders. The families and genera within the orders are listed in alphabetical order. Also included is a field guide to place sharks into the correct order.

Guitarfish
The guitarfish, also referred to as shovelnose rays, are a family, Rhinobatidae, of rays. The guitarfish are known for an elongated body with a flattened head and trunk and small, ray-like wings. The combined range of the various species is tropical, subtropical, and warm temperate waters worldwide. Names In Australia and New Zealand, guitarfish are commonly referred to as shovelnose rays or shovelnose sharks. Description Guitarfish have a body from intermediate between those of sharks and rays. The tail has a typical shark-like form, but in many species, the head has a triangular, or guitar-like shape, rather than the disc-shape formed by fusion with the pectoral fins found in other rays. Reproduction Guitarfish are ovoviviparous; the embryo matures inside an egg within the mother until it is ready to hatch. This is typical of rays. Habitat Guitarfish are bottom feeders that bury themselves in mud or sand and eat worms, crabs, and clams. Some can tolerate salt, fresh, and b ...
