Our Story
Fishheart for the
win-win-win
Fishheart is a hydraulic fishway system designed to revive migratory fish stocks in altered bodies of water.
With the help of our technological innovation, we’re aiming for a win-win-win situation: we provide migratory fish access to their natural spawning grounds, restore biodiversity and combat climate change, as well as save water and cut costs for hydropower plants.
Fishheart adapts to different environments and repositions quickly for best attraction flows. Together with the Ecological Egg Box and Stream Restoration, Fishheart offers a comprehensive solution to the migratory fish dilemma.
We believe in cooperation, and transparency is key in all our operations. Fishheart is an independent, eco-focused company looking to solve a global issue with local partners.
