The IUCN has released updates for 8,225 species and sadly, it is not looking good for many of them.
Climate change is contributing to the decline of many fish species by altering their habitats and by increasing the number of severe weather events. For example, 37% of Australian fresh water fish species are facing extinction in the wild. Of these species, 58% of them are declining due to climate change and climate change events such as extreme droughts.
One alarming example of extreme decline is the Shorttail Nurse Shark (Pseudoginglymostoma brevicaudatum) which has declined by approximately 80% over 30 years. It is now classified as Critically Endangered.
And closer to home, the Basking Shark (Cetorhinus maximus) which can be seen off UK waters from May to October has been upgraded from Vulnerable to Endangered.
BUT whilst there are people that care and fight to protect our wonderful creatures, there is hope! Two fish species which had been declining have shown population growth, which is AMAZING! The Australian Trout Cod (Maccullochella macquariensis) was once endangered but has been reclassified as Vulnerable, and the Pedder Galaxias (Galaxias pedderensis) which was once Critically Endangered has been downgraded to Endangered. They’re not out of the woods yet, but it goes to show that a concentrated effort to save species can be effective.
