  • Early Life History Comparison of the Green Sturgeon, Acipenser medirostris, and White Sturgeon, Acipenser transmontanus, of the Sacramento-San Joaquin River Delta, California by Dr. Johnson C.S. Wang, Technical Photography by René C. Reyes
    • ABSTRACT - This Tracy Technical Bulletin summarizes information concerning the early life stages of two fish species of concern in the Sacramento-San Joaquin River Delta (Delta) region of the Central Valley, California: the green sturgeon, Acipenser medirostris, and white sturgeon, Acipenser transmontanus. This information has been researched and used in the course of fish salvage operations conducted by Reclamation's Tracy Fish Collection Facility (TFCF), located in the South Delta near Tracy, California. This information provides a guide that helps researchers and fishery personnel working in the Delta to identify and distinguish the early life stages of these two important species.
