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: Not Specified
Light farming, akin to running a greenhouse but focused on fish, has seen innovative advancements at Kitasato University. Researchers have discovered that exposing fish to green LED light can accelerate their growth by an impressive 60%.
Given that Japan produces approximately 25% of the world's fish, this breakthrough in light farming could have substantial implications for the Japanese economy. By enhancing fish growth rates, this method not only promises increased yields but also the potential for more sustainable and efficient aquaculture practices.
Recent studies have shown that flatfish cultivated under green LED light grow significantly faster than those raised in traditional settings. Interestingly, the researchers initially aimed to prevent the fish from turning black, but during their investigations, they accidentally discovered the remarkable growth-promoting effects of the green light.
This unexpected finding highlights the potential of utilizing specific light wavelengths to enhance aquaculture practices. The ability to accelerate growth rates in flatfish could lead to more efficient farming methods and improved yields.
