World Fish Migration Day This World Fish Migration Day (May 25, 2024) we celebrate existing and renewed free-flowing rivers. These fish need free migration routes in order to survive.

With the World Fish Migration Day 2022 we want to raise global attention for endangered migratory fish, like salmon, sturgeon, giant catfish, dourado and eel. Migratory fish are particularly threatened by barriers such as weirs, dams and sluices, built for water management, hydropower and land drainage. Water managers, fishery organizations and NGO's are restoring fish migration routes in rivers and between rivers and seas. Dams removed, sluices are managed fish friendly and fishway are built to help fish on their journey. During this fifth World Fish Migration Day the participating organizations will open their doors for the public and will show fish and fishways and host activities for children and parents. The event will take place on the 21th of May, 2022 and is supported by WWF, The Nature Conservancy and Freshwater Fish Specialist Group. We are aiming for more than 3000 participating local, regional and national organizations.

Los peces que viajan! 🧳🐟👇🏽

Todos los años, y a lo largo del año, ocurren viajes…

Si, bajo el agua también! Miles de peces comienzan un viaje muchas veces invisible para nosotros..

Es que el río los “llama”, al aumentar el caudal, cambia la velocidad de la corriente, sube el nivel de agua y es ahí cuando los peces comienzan a migrar río arriba!

Las crecientes son LA SEÑAL!

Algunos pueden llegar a recorrer miles de kilómetros, en búsqueda de lugares donde reproducirse.

Es curioso, los adultos suben para depositar sus huevos río arriba, pero la corriente hace el resto desplazando estos huevos río abajo hacia sitios de refugio tales como valles de inundación, lagunas o humedales

Es fascinante, dispersión de especies desde donde lo mires!

En Argentina, y en especial acá hablamos de los peces de la cuenca parano-plántense, es decir de los grandes ríos, hay varias especies que realizan estos viajes, muchas de las conocidas son de las viajeras!

Dorados, Surubies, Bogas, Pacues, Bagres, lo hacen!

Hay uno en particular que es especial, es clave en la dinamica de estos ambientes, el Sábalo! Pero de eso vamos a hablar mas adelante…

Cada 2 años se celebra el dia de la migración de los peces, en .ar lo celebramos con nuestros grandes viajeros en esta sección que vamos a llamar 💙

Happy !

Rivers have always been connecting us, just like they connect fish. When we protect a free-flowing river, we protect not just the fish, we protect everyone. We are connected to fish, rivers and each other. We are culturally and spiritually connected. We are river people.

Tell us how you're celebrating in the comments!
