Regional variation in otolith geochemistry of juvenile Atlantic cod, Gadus morhua, in coastal Newfoundland
We examined spatial variation in otolith geochemistry as a natural tag in juvenile Atlantic cod to resolve geographic patterns during early life history. Individuals from 54 inshore sites spanned five embayments in eastern Newfoundland. Otolith composition differed at all spatial scales and related...

Summary: | We examined spatial variation in otolith geochemistry as a natural tag in juvenile Atlantic cod to resolve geographic patterns during early life history. Individuals from 54 inshore sites spanned five embayments in eastern Newfoundland. Otolith composition differed at all spatial scales and related inversely to spatial scale. Classification analysis revealed increasing discrimination at coarser spatial scales: site (26-58%), bay (49%), and coast (76%). Assignment success declined by ~10% per added site with increasing sampling sites per bay, demonstrating fine-scale ( The accepted manuscript in pdf format is listed with the files at the bottom of this page.
