  Have discussed a bit with the author. It seems there is still some question but someone who knows fish would have to weigh in: Not an expert by any means, but I recall a talk by Laura Cunningham on historical California ecology that spoke of the existence of Tuna in the San Francisco bay. The talk is available here, if you're a member. http://longnow.org/seminars/02011/oct/17/ten-millennia-california-ecology/ http://longnow.org/seminars/02011/oct/17/ten-millennia-calif... Susan O'Connor: * Hi Danielle, Yes I think that you are correct and immature tuna do come into shallower water but they are still difficult to catch as they are very fast moving so cannot usually be caught on a baited hook thrown offshore. Best Sue * Danielle: Hmm tricky. Are the bones you've found mostly adult? I don't have access to the paper... would you mind forwarding it? Susan: The tuna we have are mostly between about 50 and 70 cm in length so may be immatures that come close to shore. I'm not an expert but I have been advised that the tuna would not be able to be caught on the single piece circular baited jabbing hooks that I have in the site. I can't access the library from Japan so can't send you a pdf. Best Sue Danielle: Hmm, okay, thanks. Really interesting find and evidence!
