More practically, these ear bones — called otoliths — can help detect seafood fraud, manage fish stocks and give an insight into environmental conditions from the years past or even the present.

Humans have overfished cod to near extinction, so science alone cannot bring back cod. It will take regulation discipline, ...

Otoliths (Latin for "ear rocks"), have annual growth rings like trees and also absorb a variety of trace chemicals that can track the fish's movements over its lifetime.

Division biologists will measure the fish, determine the sex when possible, and remove the otoliths (ear bones) for age ...

Where do young fish hang out? Consult their ear stones. Also known as otoliths, ear stones help fish orient themselves. As a fish grows, it takes minerals from its environment and incorporates ...

Conveniently, fish harbor a perfect tool to map their habitat mosaic: ear stones, or otoliths, that accumulate mineral layers across their lifespan.

Researchers describe the use of chemical analysis of ear-stones or 'otoliths' to tease out details of a fish's life story, potentially revealing the migratory routes and environments the fish ...

Ear rocks, also known as "otoliths," are tiny pebbles of calcium carbonate in our inner ear that help keep us balanced. They're located deep inside the inner ear in a small pouch called a utricle ...

Sandy Darnell, a retired commercial fisherwoman, continued her love of fishing and now creates earrings and pendants out of the hard, roughly circular fish ear bones called otoliths.

The N.C. Department of Environmental Quality’s Division of Marine Fisheries will collect Red Snapper carcasses from ...

Also known as otoliths, ear stones help fish orient themselves. As a fish grows, it takes minerals like calcium from its environment and incorporates them into its otoliths in a series of layers ...

In the space age, physiologists are learning much more about these otoliths (ear stones), which respond to forces of gravity or acceleration.
