Can otolith chemistry unravel the mysteries of the Newfoundland cod?

No abstracts are to be cited without prior reference to the author.

Two decades after the moratorium on Newfoundland and Labrador Atlantic cod (Gadus morhua) fisheries, science has yet to unravel their complex stock structures and distributions. Rebuilding these depleted stocks requires better knowledge of movement patterns and the degree of connection between major spawning groups. The chemical signatures of otoliths provide chronological data on the life environment of fish enabling study of natal sites, life migration patterns and connectivity among spawning sites.
