國際自然保護聯盟 IUCN 2021追加軟骨魚物種

posted in: Uncategorized | 0

國際自然保護聯盟 IUCN 追加39個鯊魚魟魚物種到瀕危名單。 1100種軟骨魚 ( 420+ 鯊魚& 650+ 魟魚)當中,有355種為受威脅(VU易危, EN瀕危, CR極危)物種。

New updates on the conservation status of sharks and rays released today by the International Union for Conservation of Nature (IUCN) show that 39 additional species are now facing a risk of extinction in the wild. This takes the total of all sharks and rays categorised as Vulnerable, Endangered, or Critically Endangered to 355.

爪哇鹞扁魟Urolophus javanicus, 一種印尼爪哇的特有種,在十九世紀末之後就再也沒有目擊紀錄, 推斷已經滅絕。

Most alarmingly, IUCN reveals that one species of ray may have already gone extinct, as the Java stingaree (Urolophus javanicus) is now assessed as Critically Endangered (Possibly Extinct). A unique ray from the coast of Java in Indonesia, it was previously listed as Critically Endangered (2006). This endemic species has not been seen since the end of the 19th century when it was originally discovered.

九種新被列入極危的軟骨魚當中,有八種是燕魟和鰩。

Eight out of nine species that are “uplisted” to the Critically Endangered category – meaning they are just one step away from extinction – are rays (mostly guitarfishes and eagle rays). This continues the worrying trend that although rays may be less known and do not receive as much attention, they are doing even worse than sharks as a consequence of overfishing and overall lack of fisheries management.

不僅是無名的物種上榜此次的紅皮書,明星物種如加勒比白眼鮫 (Carcharhinus perezi) 從近危NT升等到瀕危EN,短吻檸檬鯊(Negaprion brevirostris)從近危NT升等到VU易危,鉸口鯊(Ginglymostoma cirratum)從數據缺乏DD升等到VU易危。

Nonetheless, it is not just the lesser-known species featuring in this round of Red List updates. A few reef sharks that used to be very common and abundant, and are particularly popular among divers, are now threatened. This includes the Caribbean reef shark (Carcharhinus perezi) reclassified from Near Threatened to Endangered, lemon shark (Negaprion brevirostris) from Near Threatened to Vulnerable, and the Atlantic nurse shark (Ginglymostoma cirratum) from Data Deficient to Vulnerable.

2014年25%的鯊魚和魟魚受威脅,其中25個物種極危。

2021年36%的鯊魚和魟魚受威脅355, 極危物種從25增加到76種。112 個物種瀕危,167 個物種易危。

Ever more species of sharks and rays are being pushed towards extinction. In 2014, 25% of all shark and ray species were threatened, with 25 species critically endangered. Right now, 36% per cent is under threat and the number of critically endangered species has tripled (from 25 to 76). 

76 shark and ray species are now critically endangered, 112 are endangered, and 167 are vulnerable.
