UV-B light blinds barnacle larvae in 60 minutes, then no attaching

[sdowney717]

So I see you can buy UV-B aquarium lights. How many underwater lights do you think you would need at your slip to slow down the barnacles?

UV blinds barnacles : Nature News

Au and her colleagues exposed barnacle larvae to a dose of UV-B radiation comparable to the level Hong Kong receives on a typical summer afternoon. The larvae were blinded within 60 minutes, and were unable to swim towards light.

The sightless larvae were also unable to latch onto the surface of a glass beaker or settle. In the ocean, this means that they cannot mature into adults, with their characteristic volcano-like shells.

Now wouldn't that be interesting.

Bling lights with a purpose.

Heck, in my neck of the woods, all the extra-low-slung vehicles already have those fancy full-perimeter stick style UV foglights! They're water-resistant to boot ... ready to make serious maritime fashion statements all over the world ...
