Opah - The Science
An International Fish of Mystery
NOAA scientists are working collaboratively with Catalina Offshore Products to collect the information needed to understand the opah’s behavior, diet, age, growth, and reproduction. These data will allow NOAA to develop management strategies for this little known fish, as there is currently not enough information to conduct a stock assessment.
This work would not be possible without the collaborative support of fishermen and the seafood industry for regular access to San Diego caught opah for sampling.

Matthew Craig, PhD
Heidi Dewar, PhD
Prior to joining NMFS in 1985, Helvey was a research associate at Occidental College where he examined fish interactions with southern California offshore water intake structures. He holds both a Bachelor of Science and Master of Science from the University of California, Santa Barbara and the University of Arizona, respectively, and a Master’s in Business Administration California State University, Long Beach. His present interests revolve around seeking sustainable fishing opportunities for U.S. harvesters and producers.
John Hyde, PhD
John received his PhD from the Scripps Institution of Oceanography and has been actively involved with marine biology research in southern California for 20 years. In addition to his research experience, he has been an avid boater, scuba diver and fisherman his whole life.
