Light from Salmon what???

Endgadget is freaking out over a joint University of Cincinnati/Air Force breakthrough creating an environmentally friendly light source, called BioLEDs, out of salmon sperm:

The so-called BioLEDs are being developed in cooperation with the Air Force (yes, the Air Force — they had a “good source” of salmon sperm, apparently) and they’ve been so successful that Steckl has been getting salmon sperm from researchers worldwide “wanting to see if their sperm is good enough.”

I seem to remember an episode of Iron Chef (the pre-Food Network version) revolving around a similar ingredient, but apparently this is considered a waste product by the fishing industry.
