The Fish Doorbell — The Fish Doorbell Did you spot a fish? Press the Fish Doorbell! This alerts our lock operator to let the fish through. The Fish Doorbell is in Utrecht, NL.

Yay! It's Fish Doorbell season again!

Any project that lasts less than 100 years and cost 100 immediate deaths & thousands+ lives later, is NOT a success.

We usually think of fish migration as part of reproduction, but that’s only part of the story.
Discover 3 key reasons why fish migrate and learn how healthy, connected rivers make it possible.

We hope you can escape the showers this weekend and enjoy a lovely autumn walk. If you are near Golitha Falls, you can visit our information board to learn how the #WaterforGrowth project helped increase migratory fish in the River Fowey.

🎬 Throwback to our DanubeLifelines kick-off in Vienna!

Grateful to @bokuvienna.bsky.social for the tour of their floating fish research station on the Danube.
Big goals, big river, big collaboration.

Let’s reconnect the rivers.

📢 New IMR research reveals alarming effects of overfishing on herring 🐟 Age-selective fisheries caused an 800-km poleward shift in spawning, disrupting collective memory and migration patterns. #FishMigration #FisheriesManagement

38°F rain- not a great day for Middleborough Herring Fest.But the river herring are running, I spent the day by Nemasket River talking to people who braved the weather to celebrate their return, & got sparkly fish face paint! 🐟

🎣 Climate Change Fish Migration Patterns Are Redefining Fishing Grounds 🌍🐟

We explore how climate change is transforming where fish live — and how you can adapt your strategy to keep catching.

Original post on mastodon.cosmicnation.co

In Utrecht, Netherlands, a unique 'fish doorbell' livestream allows viewers worldwide to help fish migrate during spring by alerting authorities to open a river lock. This innovative project has attracted millions, combining ecological activism with relaxing 'slow TV.'

One way to invest in people & planet is by upgrading existing #hydropower plants. Hydropower provides 24/7 #renewableenergy, but many facilities can disrupt #fishmigration and #river ecosystems.

Like flyways for birds, we need to map swimways for fish Mapping fish migration routes and identifying threats is crucial to protecting freshwater species and their habitats, ecologists argue.

Weirs are bad for rivers. They interrupt the flow of water and sediment making them less resilient and able to support our iconic species. Important discussions to be had here on how to restore that connectivity #rivers #freeflowingrivers #fishmigration #connectivity #wildatlanticsalmon
