Jonny Posted June 10, 2009 Report Share Posted June 10, 2009 I had heard about these, but never seen one. Their purpose seems to be to give the fish balance. Apparently native people used to think they had some mystical power. People nowadays sometimes use them for jewelry. Supposedly they're the closest thing to ivory in a fish. These otoliths, from about a 7 lb. drum, are about the size of a nickel, and in texture and weight they feel like broken pieces of river pebble, not bone. I found an internet site that showed a diagram of how to remove them, so I decided to try it. You have to cut the head exactly in half longitudinally - quite a chore, even with a heavy hunting knife. When you've done that you can make out the pockets that the otoliths are in (marked in the photo). Clear away a bit of very soft tissue and you can gently work them out with the tip of your knife. A couple of pics I took: Link to comment Share on other sites More sharing options...

Jonny Posted June 10, 2009 Author Report Share Posted June 10, 2009 Then what do you do with them? I dunno. Make a pair of earrings? I know of at least one lodge on Nipissing that will cut them out for you if you want them. Souvenir, I guess. Link to comment Share on other sites More sharing options...
Bob Posted June 10, 2009 Report Share Posted June 10, 2009 Put them in a tumbler to polish them, drill a hole in each and string them like beads. Or make earings. Link to comment Share on other sites More sharing options...

Jonny Posted June 10, 2009 Author Report Share Posted June 10, 2009 (edited) Age your own sheepshead? What otoliths are really used for Yes, I learned that by searching around, but I wouldn't want to destroy one by cutting it apart. To each their own bud...Ive dissected enough of these for various studies that I wouldn't do it for kicks I can see why! Well it's the first I've ever tried it, and maybe the last if I don't use them for anything. Kind of interesting when it's a first-time thing, but I can see that the novelty might fade pretty fast unless you used something like a bandsaw! --- Bob, wouldn't a tumbler break the edges?

Of course, but that's so ya don't carve up yer ears when ya start wearing the new sporty earrings ya made. It's getting evermore dangerous to be a he-man fisherjock, isn't it?

Yeah, Roy, it does look like a butcher shop in that one photo. I couldn't think of another way to show how it's done. I visited some sites where it was only described or diagrammed and they were of limited help. Cutting up any animal is not my favourite thing to do, and this was a little more distasteful than just filleting a fish, for some reason. But like they say, "You can't make an omelette without breaking eggs". Cutting the antlers off a moose or deer is no fun either. --- No, John, no parrot. I don't want to be stereotyped.

Spiel Posted June 10, 2009 Report Share Posted June 10, 2009 Well that was interesting. You know I've known of these otoliths (we just called 'em stones) since I was a kid and never once did I actually go in and dig 'em out and I think now I know why. Thanks for the anatomy lesson JPJ.

richyb Posted June 11, 2009 Report Share Posted June 11, 2009 I think all fish have them , at fleming we took odoliths from the odd dead bluegill, pumpkin seed , walleye caught in our nets. If you use a diamond edged cutting tool you can cut them in half and use a microscope to check the fish's age. They have rings like a tree.

mikeh Posted June 11, 2009 Report Share Posted June 11, 2009 I was just wondering how many rings it had? do you have to cut them in half to see the rings? just curious as I don't see myself doing it anytime soon. Link to comment Share on other sites More sharing options...
Bob Posted June 11, 2009 Report Share Posted June 11, 2009 Cleans the edges off for sure but they are nice looking when they're done. Don't put heavy stuff in the tumbler with them. Link to comment Share on other sites More sharing options...
