Smelt Research
During the rearing of smelt fry, the smelt are marked by dipping them in a dye that stains the ear bone, odolith, of the smelt. As the smelt grow, the odolith grows covering the stained layer much like growth rings on a tree. The smelt are then released during our Smelt Stocking Project.
MLFC collects samples of smelt from the stomachs of lake trout and salmon caught lake wide during ice fishing and open water seasons.
The odoliths are then removed from the sampled smelt and sent to Unity College for testing. The odoliths are ground down and placed in a powerful microscope to reveal the growth rings. If the odolith came from a marked smelt the marked growth ring will be visible.
