We caught some Mai hi yesterday and we found this in his stomach. You know us fisherman we have to see what they have been eating. It looks like a juvenile bill fish of some sorts. Here is a general description; on each side there is some hard bony scales that run from the head to the tail. The dorsal is a bit damaged but you can see the rest pretty clear.
Dayne, you can also send the hi-res version of this pic to email@example.com for a possible ID by one of Sport Fishing's experts. (If we publish it in the magazine, you could get some Berkley line.)
