New hopes for sharks, catfish, and silver 鳐 species: important sharks and catfish areas

Chinese biological diversity protection and Green Development Foundation (referred to as China Green Fair, Green Association), as a member of the World Nature Protection Alliance (IUCN), continues to pay attention to the latest developments in global natural protection and governance. A few days ago, the International Department of China Green Fair learned from the World Nature Protection Alliance: new hope for sharks, catfish, and silver soda species: important shark and catfish area (ISRA). The International Department of the Green Club now compiles this article for reference for interested readers.

A latest study published in "Frontiers of Marine Science" emphasizes that the global recession problem of cartilage fish (sharks, catfish, and silver pupae, hereinafter referred to as "Shark") has become more urgent at any time in the past, and measures are urgent to formulate measures to solve solutions Essence The paper entitled "Putting sharks on a map: Global Standards for Protection of Shark Area" summarizes a set of important sets of shark and catfish area (ISRA). Losses, and incorporate these into regional planning.

Why do sharks need to be protected?

The latest World Nature Protection Alliance (IUCN) Endangered Species Red List (hereinafter referred to as "IUCN Red List") evaluation of sharks show that more than one-third of shark species (37%, range of 32.6-45.5%) are facing the threat of extinction. (That is, it is considered to be extremely endangered, endangered, or susceptible to danger). Three -quarters of marine species are facing extinction threats.

At present, measures to protect and improve shark habitats do not work. However, regional protection is the cornerstone to prevent the loss of biological diversity. With the support of the IUCN Ocean Team and the IUCN marine mammal zone working group, the World Nature Protection Alliance Species Species and Species Species and Species have developed an important shark and catfish area (ISRA) to ensure the shark species. The discrete part of the vital habitat is divided and used for various regional protection and management measures for the global ocean.

What is an important Shark and Ray Areas (ISRA)?

ISRA is a vital discrete, three -dimensional habitat for one or more shark species. These habitats are designated and may be managed and protected. Isra is not a marine reserve (MPA), and they are not authorized or regulated by law or regulatory authorization. Therefore, Isra completely separated from any possible supervision or relief of any possible human activity. However, one of the main goals of ISRA is to attract the need to design and develop these MPA policies and decision makers noticing the necessity of maintaining a good protection state of sharks in these specific areas.

The standard design is to determine the important aspects of shark biology and ecology, including the vulnerability, distribution, abundance and key life cycle activities of species, as well as high diversity and local areas.

Sharks are essential for maintaining a balanced ecosystem. Sharks have shaped fish communities, ensuring the diversity of species, and even helping the ocean to seal more carbon by maintaining seaweed meows. Sharks are particularly susceptible to fishing pressure and threats related to habitat (such as deep -sea mining). Local protection methods, such as Isras, will play a key role in preventing its decline and guidance to formulate effective protection and management measures.
