Short Description of your Research or Creative Project (700 characters or less)
Otoliths or fish ear bones allow us to estimate the age, birth/hatch date and growth of fishes. Juvenile rockfish were collected from Standard Monitoring Units for the Recruitment of Fishes in Trinidad Bay in collaboration with the Trinidad Rancheria. ~14,000 juvenile rockfish were caught and 19 were retained for this study. These fish were 41-65cm and collected between May and September. These otoliths will show growth rates and birth dates to better understand early life history of local rockfish populations.
