DNA Barcoding of Caviar Indicates that Regulation Can Curb Illegal Trade

Research posts

Research that used DNA-based testing to compare the extent of fraudulent labeling of black caviar purchased before and after international protection shows conservation benefits. A team of scientists from the Institute for Conservation Science at Stony Brook University and the Sackler Institute for Comparative Genomics at the Museum repeated a market survey of commercially available caviar in the New York City area that was conducted before the protection was put in place, and the results showed nearly a 50 percent decrease in fraudulently labeled caviar.

The research, published this week in the journal PLoS ONE, compared the results of two market surveys conducted 10 years apart. The previous market survey was conducted from 1995 to 1996, before sturgeon was listed under the Convention on International Trade in Endangered Species (CITES) in 1998. That survey revealed that 19 percent of commercially available caviar in the New York City area was mislabeled with respect to species origin. When sampling the same market from 2006 to 2008, fraudulently labeled caviar occurred in 10 percent of the caviar, and only in the samples bought online.

Researchers have described two new ancient species of South American rodents, including the oldest known chinchilla, in a study published last week in American Museum Novitates, a peer-reviewed scientific journal of the Museum. The research, which was led by Ornella Bertrand, a recipient of the Museum’s Annette Kade Graduate Student Fellowship, substantiates what might be the earliest grasslands in the world.
