BAR CODE? NO, 'BONE' CODE; INTERMEC DEVELOPS ANOTHER 'SYMBOLOGY'

 EVERETT, Wash., Dec. 16 /PRNewswire/ -- Intermec Corp., in conjunction with the Washington State Department of Fisheries, has helped developed a bar code pattern which is being naturally encoded in the earbone of fish to track source hatcheries, Intermec announced today.
 According to Eric Volk and Steve Schroder of the Washington State Department of Fisheries, scientists have long known that the calcified element in the ear of fish, called an otolith, shows daily growth rings. Slightly lowering the incubation water temperature for brief periods induces distinct differences in these rings in fish embryos.
 Intermec's Sprague Ackley began working with Volk to develop a two-of-five pattern, similar to Intermec's Interleaved 2 of 5, for naturally coding the fish because it is easily recognizable to the human eye. Ackley also provided decode algorithm technology to help automate the entire process.
 Mass marking hatchery fish will allow the Washington State Department of Fisheries to track their origin. The project is of great importance to the economy of Washington, and other states as well, considering the commercial and recreational impact of the fishing industry on the state.
 Approximately 2 million salmon embryos were marked with the two-of-five pattern over a period of 14 days at the Cowlitz Hatchery in Washington state simply by lowering and raising the water temperature. After one month, a sample of fish was harvested, and the otoliths were removed. The sectioned otoliths were viewed under high magnification to reveal the two-of-five pattern for the digit "6."
 Research is continuing at the Washington State Department of Fisheries with a project currently involving 10 different incubation environments being used to encode 10 different digits. In addition, research is continuing with automatic computer analysis of hatchery fish. This technique eventually could be used to uniquely identify fish from every hatchery, and even sub units of hatcheries. Such identification will help researchers study pollution, habitat damage and survival rates to ensure the greatest benefit from fishery resources.
