Part 2 of the stable isotope project will be analyzing sea catfish #otoliths using carbon and oxygen stable isotope analyses
Otoliths are calcium carbonate structures or “stones” in the inner ear of most fish 🐠
The sea catfish otoliths are very round, but you can also get different shapes like this #dageraad
The goal is to determine the season of catch and to reconstruct body size
