Fish don’t lie and they don’t have political agendas. Pacific 2026: mahi mahi off San Francisco. Marlin off Washington. Yellowfin tuna in Alaska. Mackerel off Japan down 75%. Marine species moving poleward at 72km per decade — 10× faster than land species. Moving faster doesn’t save them. A 17km/yr shift = 50% population decline. The fish are tracing the exact same corridor the SST data shows — Japan to Alaska, NE axis, following warm water that shouldn’t be there. Today NOAA declared El Niño. The fish declared it months ago. #ElNino #FishMigration #Pacific

🚨🆕 @MassEcoRestore Director Beth Lambert discusses how #Massachusetts led the nation in removing obsolete dams in 2025, eliminating #flood and #drowning hazards and restoring rivers for #fishmigration! #damremovals #riverrestoration podcasts.apple.com/us/podcas…

Glædelig #WorldFishMigrationDay 💚☺️ Ferskvandsnatur og de arter somer lever der, er den mest truede kategori på verdensplan! Danmark bør gøre sin del for at skabe bedre og mere sammenhængende ferskvandsnatur #VildGudenå #FreeflowingRivers #DamRemoval @fishmigration

Every year from mid-April to early May, Huazi fish swim upstream along the Gongger River to spawn. To protect this annual migration, authorities in northern China's Inner Mongolia regulate water use and impose temporary fishing bans. #Nature #Wildlife #FishMigration #InnerMongolia #EcoTourism #Conservation

What an exciting and passionate talk by @shagi1983 at the First Asian International Eel Symposium #FAIES as he chases anguillid eels across the tropical Asia Pacific #anguillideels #migration #fishmigration @NecoBus_8110 @ChungTsung

First-ever sighting: Thousands of Rhyacoglanis paranensis #BumblebeeCatfish in Brazil 🇧🇷 were filmed climbing a waterfall 🐟🌊 — a rare “massive aggregation” likely tied to #spawning #migration. 🔍#FishMigration miamiherald.com/news/nation-…

Today, we spotlight a silent struggle beneath our rivers — dams and barriers that block fish from reaching their spawning grounds. 🐟 Read our blog: intlrv.rs/3HmOnRX @jacqules #FishMigration #DamRemoval #FreeFlowingRivers

Today we brought the DiadSea board game and card game to Teixeira de Pascoais Elementary School! 🌊🎲🃏 Students learned about the challenges faced by diadromous fish during migration, exploring threats and solutions through interactive play. #DiadSea #FishMigration @MAREscience

Advice needed. Video shows recently built fish passage into an abandoned dam in #Francolí river (Catalonia). Is this design suitable for eels? @DamRemovalEU @fishmigration @MiljoChrister @LetRiversFlow @DamRemovalNow @EelStewardship @intlrivers @StoeckerEco @EeacGete @eelgroup

WQ: "...#fishmigration event where many salmonid species,which are typically #hatchedinfreshwater& live most of their adult life downstream in the ocean,#swimbackagainstthestream to the upper reaches of rivers to spawn on the gravel beds of small creeks."🔎en.wikipedia.org/wiki/Salmon…

Frustrating that so many seemingly modern ones have been put in with no thought for river life. The oldest was probably the 'least bad'!
