Wildlife department says drought conditions and water released from dam led to ‘major fish kill’ at San Carlos Lake

Arizona officials have indefinitely closed a popular lake to visitors after its entire population of fish died recently.

The recreation and wildlife department that maintains San Carlos Lake said in a Facebook statement on Friday that drought conditions as well as water released from a dam there “resulted in a major fish kill affecting approximately 100% of the fish population”.

Record numbers linked to warming waters is mixed news for fishers, with shellfish catches down but octopus catches booming

Record numbers of octopuses found off the south-west coast of England last year have now spread as far as Scotland and Wales and are transforming the fishing industry and the marine ecosystem, according to a study.

The surge in sightings of one of the world’s most intelligent invertebrates was first recorded in 2025 off the south coast of Devon and Cornwall.
