Age and Growth Lab
The Age and Growth Lab is responsible for the processing and aging
of fish otoliths for the purpose of stock assessment. Find out why
and how we age fish.
Otoliths help FWRI biologists to determine age and derive
age-related information as well as growth rates of various fishes.
In 2011, the Age and Growth Lab processed and aged over 22,000 otoliths from 33 species of fish. Read this article to find out how FWRI processes and uses otoliths for research.
Researchers use otoliths, commonly known as earstones, to estimate
the age of a fish. Learn more about this process and view otoliths
from nearly 90 species of fish.
