Incredibly Ingenious: Japanese Inventions You Can't Find Elsewhere

10. Light for Fish Growth

What It Is: Fish develop 60% quicker when exposed to green LED light. Average Cost: With fish instead of plants, light farming is quite similar to running a greenhouse. Green light may be used by researchers at Kitasato University to accelerate fish growth by 60%, according to Nippon. With Japan producing about 25% of the world's fish, this development in light farming has the potential to significantly impact the Japanese economy.

It's interesting to note that when the researchers began their work, they were trying to figure out how to keep fish from turning black. It was by accident that they found the growth-promoting properties of the green light.
