(Saving Seafood) – Warning that within our lifetimes, the worlds supply of fish could collapse entirely, the startup news website OZY last week promulgated claims about the depletion of ocean fish based on 7-10 year old studies that were controversial at the time of their publication, and have been largely disproven by multiple scientific authorities in the ensuing years.

One of OZY’s allegations was that even pet goldfish would disappear.
The article begins with the statement “Whether its tuna sashimi or lobster bisque, we love our seafood so much so that the ocean cant keep up.” But in fact, after an independent, third-party assessment, Maine lobster was declared a “sustainable and well-managed fishery” at the International Boston Seafood Show by the internationally-recognized Marine Stewardship Council on March 13 of this year.
This OZY story is the latest to cite the claim that the population of bluefin tuna has dropped almost 90 percent since the 1960s in the Atlantic, Pacific, and Southern Oceans. This claim originated in a study, published in 2003 by Drs. Ransom A. Myers and Boris Worm, of Dalhousie University in Nova Scotia, Canada (Nature, vol. 423, 15 May 2003, pp. 280-283), which reached its conclusions using data on bluefin tuna taken only from longline fisheries. In a paper published over fifty years ago (Pacific Science,Vol. XVI, January 1962) Vernon Brock of the U.S. Bureau of Commercial Fisheries noted that “Longline gear, as used for tuna fishing, characteristically takes the larger tuna.” Since longline gear selectively targets larger bluefin, fish caught using longlines are not a representative sample of the species as a whole.
The studys conclusion that the tuna population has declined by 90 percent has been challenged by Dr. Maria Jos
