How do you figure out how old a fish is? Very carefully. Most fish have small​ bones in their inner ears​ called otoliths, made of calcium carbonate. They’re located in a fish’s inner ear and help with hearing and balance. As a fish grows, new layers of calcium carbonate are deposited in layers, much like the growth patterns seen in tree rings. We can count the growth rings to determine the fish’s age. Why not determine their age based on their size or weight? Like humans, fish stop growing at a

Otoliths exist in bony fish and other animals and they help facilitate balance and motion detection. Folks on BC’s coast often dig them out and make jewelry out of the ones that come from rockfish. #explorebc #nature #otolith #biology #marinebiology | BC Bob

Fish have ear stones that grow rings like a tree 🌲🐟 — and Washington hatcheries discovered they can actually create a barcode inside the otolith (aka ear bone) just by adjusting the water temperature. That means scientists can track salmon migrations and know exactly where they came from. How wild is that?! 🎧 Listen to the full episode to hear the full story, and comment BARCODE and we’ll send you the link! #saltwaterfishing #Salmonfishing #PNWfishing #saltwaterfishing #pnwlife | Jamie Propst
