A recent Atlantic-wide tag-recapture experiment run by the International Commission for the Conservation of Atlantic Tunas was an opportunity to directly validate otolith increment deposition rates for bigeye tuna (Thunnus obesus) and yellowfin tuna (T. albacares) in the region.

The results of this study provide additional evidence of ovarian masculinization in the Atlantic croaker (Micropogonias undulatus) in and around the hypoxic zone in the Gulf of Mexico and the first evidence of ovarian masculinization in the spot (Leiostomus xanthurus) and bigeye searobin (Prionotus longispinosus).

A bottom-trawl survey with a stratified-random sampling design has been used to inform stock assessments for commercially important species in the Gulf of Alaska since 1984. A new stratified sampling design was evaluated to determine whether its use could improve the precision and accuracy of abundance estimates. Read the article (PDF, 17 pages).
