- Investigate the degree to which the gills of the wahoo are specialized for oxygen transfer

WAHOO UPDATE - October 2006
 PIER
Researcher Chugey Sepulveda and colleagues recently returned from a wahoo tagging trip along the
Baja Coast.
Despite adverse weather conditions and slow
fishing, the team successfully deployed over 20 archival
transmitters in wahoo along the “ridge”, a productive area outside
of Magdalena Bay, Baja California. To date we have already received
two wahoo re-captures that now provide high-resolution
temperature-depth data for this species.
Our research team thanks Tom Pfleger for his
generous support of this project.
