"We catch approximately 2.5 million metric tons of fish in Alaska. ... approximately half of that — 1.3 million metric tons — would be the waste' said Peter Bechtel, a USDA food scientist at the University of Alaska's Fisheries Technology Center at Kodiak. "We have just a huge amount of material in Alaska that isn't made into fillets and it isn't roe, and we need to do something with this."
