conjunction with genetic research and tagging stud- 
ies may be able to answer questions pertaining to 
location and number of king mackerel groups. 
Acknowledgments 
This work was funded in part by the Environmental 
Protection Agency (cooperative agreement CR- 
818222). We are grateful for the useful discussions 
with John McEachran, Churchill Grimes, and John 
Gold, whose knowledge of the species was critical in 
formulating this manuscript. Barbara Palko (NMFS, 
Panama City, FL) and John Gold (Texas A&M Uni- 
versity) obtained the fish used in this study. We thank 
Alan Abend, John Pohlman, Dan Roelke, and Beth 
Trust who reviewed the manuscript. We would also 
like to acknowledge the reviewers of this manuscript 
who did an exceptional job.
