I guess they look more like a glass bead. I took out people last weekend to Homer. On the way down this guy was talking about his grandpa showed him this trick on a certain fish from back east. He said, "I bet these halibut will have them too, even though I have never seen or caught a halibut." Well after a days fishing and back at the cleaning station. I was filleting and remembered what he was saying and asked him to show me. Sure enough the halibut have them. So on most of the fish I cut out the Fish Ivory-ear bones, and then cut out the pearls. Freakin wierd. Never heard of this and still have to experiement. Next time I am going to try a bait needle from B&J's. When the pearls first come out they are soft and kinda sticky once they start to dry. I am thinking of threading them on to small mono while they are in this stage. Then can pull them off and put onto jewelry. It just tripped me out. They are kinda discusting to remove though. But being they are so interesting I could get past it. So has anyone found these before? If not guess where they came from. I am aslo wondering if all fish have them like the ear bones. I think the ear bones, Otiliths are pretty cool too. Rock fish have pretty cool looking ones.
