What is a fish scale and why should you consider keeping one in the boat? Fish scales are a measuring tool that anglers use to keep track of their progress on the water. Some anglers set goals to beat their PB (personal best catch) year after year. What is your scaled PB catch to date? Check out @Takemefishing or takemefishing.org to find places to go fishing based on your location! #anglerlife #catchandrelease #fishingadventure #takemefishing | Take Me Fishing

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

Did you know that some fish have Otoliths or Ear Stones? Your Saltwater Guide is Sponsored by Fishing Booker. | Your Saltwater Guide

How do you age a fish? As it turns out, kind of like a tree... Otoliths (Greek for “ear-stone”) are calcium carbonate structures found beneath the brain of most fish that aid in balance and hearing. Otoliths continuously accrete calcium carbonate throughout the fish’s life, forming bands on the otolith -- much like rings of a tree. Scientists can use these bands to tell the age of a fish. Scott France, our science lead on our previous Voyage to the Ridge expedition, explains more in this video.
