White Seabass Population Dynamics
This collaborative project investigates white seabass population dynamics with colleagues from CICESE
(Centro de Investigacion Cientifica y Educacion Superior de Ensenada), in Baja California, Mexico. Collectively this work tests whether the white seabass caught along California and Baja California (Norte and Sur) represent the same stock, or whether there are distinct populations with limited mixing. The study uses a combination of otolith microchemistry and age/growth characteristics to compare individuals from multiple sites along California and Baja California.
Because the white seabass is a trans-boundary resource that supports vast commercial and recreational fisheries in the U.S. and Mexico, determining the different nursery areas and understanding the population dynamics of this species is critical for effective management. The California Department of Fish and Game
has recently highlighted the importance of understanding white seabass movements and the degree to which we share this resource with Mexico.
This work is being conducted in the laboratory of Dr. Sharon Herzka (CICESE) with graduate student Alfonsina (Kena) Romo Curiel heading up the investigations.
