Lutcavage revealed a number of interesting revelations that have come about through the use of genetic markers and DNA studies of bluefin. One that I found astounding: The latest information strongly suggests that a larger number of young-of-the-year bluefin spawned in the Eastern Atlantic swim to the waters off the East Coast of the United States, an amazing journey for fish so small, and they appear to stay here for years. What is driving young bluefin to undertake that journey remains unexplained. Conjecture is that the Mediterranean no longer holds the forage base it once did and they truck over in search of more productive hunting grounds. Others surmise it could be simply something programmed into their DNA.
