SILVER SPRING, Maryland, Nov. 17 -- The National Oceanic and Atmospheric Administration issued the following feature story:
Conventional observations show that spiny dogfish in the western North Atlantic rarely eat Atlantic cod. However, some believe the rebuilding dogfish populations are limiting depleted cod numbers by competition or predation. To find out what is going on, NOAA Fisheries scientists looked to genetic testing to confirm cod presence in dogfish stomachs.
