Flexible, durable, continuous extrusions with misting ports embedded in the tube hangar assures low stress, low pressure passage on a moist cushion of air, regardless of height. The proprietary blend of materials is unlike any other tube that has been produced before.  After five years of research and development and another five years of rigorous studies and real-world deployments, and we are confident in saying that there is not a safer way for a fish to get from point A to point B, and passage any obstacle quickly, efficiently, and safely. The concept was revolutionary a decade ago, today its just smarter (and cooler) fish passage, that can improve survival and fecundity, now more than ever, in an era of cliamte changes.
