"Hi Bill,

What can you tell me about Allison tuna? Just read one of Zane Grey's books that contains reports of Allison Tuna being caught in the eastern Pacific in the 1920's. Is that a different name for a species that is caught there now? Or is that a different species that is no longer found there?"

Hi, Don:

Some scientists once thought that tuna with very long sickles were a subspecies or a different species of yellowfin; "Allison's Tuna," they called them. But there was no other major difference, so now all yellowfin are considered the same species, as far as I know. In places like Australia and Hawaii, the term "Allison's Tuna" is still in use. There's nothing to keep yellowfin tuna from different hemispheres from intermingling.
