Dunng the Sea Grant study, the same species was obtained from both marine and freshwater fish, further suggesting that certain Ichthyobodo species may not be limited by salinity. The researchers also demonstrated that DNA sequence differences between costia species can be used consistently for identification. "With more research, DNA sequence differences may help determine the types offish that can be stocked together," says Callahan. "They also might be used to determine risks involved with using water from local waterways that may provide a way to transfer Ichthyobodo between feral and cultured fish species. In addition, DNA differences between species could be used to differentiate more virulent or treatment-resistant species and strains prior to the importation or exportation ; To read the article: visit the Web: www.

But this spring it was the Graveyard of the Atlantic — Museum, that is — coming to the rescue of the famed Hatteras Light. Volunteers joined experts to restore the "first order" Fresnel lens — including 400 sea-green crystal prisms. The original 6,000-pound lens, was state-of-the-art technology when it was built in Paris in 1853. Removed from the Hatteras lighthouse during the Civil War, the lens was thought to be lost — until 2002, when author Kevin Duffus' search through the National Archives revealed that the lens was in storage at the National Park Service. - Sport Fishing School Set for June I he 53rd An
