Extracting fish otoliths without trending audio from a red snapper (Lutjanus campechanus) 🐟🐠
Otoliths are used to calculate a fish’s age by counting annually deposited growth rings, similar to counting tree rings.
Red snapper can live up to 40 years old, and inhabit benthic hard-bottom reefs in the western Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico.
This permitted collection was performed during a reef fish survey in the U.S. south Atlantic this past summer to assess reef biodiversity and species abundance.
