The bizarre clip shows how a pressurised, flexible tubing sends the fish from one plot of water to another.
Whoossh Innovations Fish Transportation System created the bizarre system in 2011 to safely transport native fish over a dam, but the footage has only just emerged of it in action.
The clip starts with a fish, thought to be a 29kg Huchen salmon, being loaded into the opening of the tube.
It quickly travels through the soft tubing, moving over parts of land before shooting out the other side.
The creature falls out into another plot of water seemingly unhurt.
Whoossh Innovations created the fish passage system to effectively help with fish migration.
Salmon have to migrate from the ocean and swim upstream.
After they spawn on gravel beds they die and the salmon life cycle starts again.
The new system will ensure more salmon are able to spawn after a rise in hydroelectric dams sees them fighting powerful streams.
And since footage of the system has been uploaded to Twitter, a whopping 16.8million people have watched the clip.
A barrage of memes flooded the comments section, with many creating what they believe the fish sees during their travels.
One person commented: “I’m screaming.”
A second asked: “What if the fish are claustrophobic?”
Another asked: “How does it differentiate between native and non-native species? Is there a checkpoint where fish customs agents ask for your fish papers?”
Some weren’t as impressed, though, with many believing the system was “cruel”.
