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

  • Figure 1 - Green sturgeon eggs, larvae, and prejuveniles. Green sturgeon eggs were provided by Joel Van Eenennaam, UCD, and incubated at 15.5 °C at the TFCF. TL = total length. Photographs are not to scale.
  • Figure 2 - White sturgeon eggs, larvae, and prejuvenile. Eggs provided by Stoltz Sea Farm, Galt, California. Eggs and larvae incubated at 16 °C and raised at the TFCF at 18 - 19 °C. TL = total length. Photographs are not to scale.
  • Figure 3 - Comparing the eggs of green (left) and white (right) sturgeons. Green sturgeon eggs were provided by Joel Van Eenennaam, UCD, and incubated at 15.5 °C. White sturgeon eggs were provided by Stoltz Sea Farm, Galt, California, and incubated at 16 °C. Eggs developed and were photographed at the TFCF at 18 - 19 °C. dps = days post spawn.
  • Figure 4 - Images comparing same-sized larval green (left) and white (right) strugeons. Specimens were raised at 20°± 1 °C at the TFCF. mm TL = millimeters total length.
  • Figure 5 - Images comparing same life stages of green and white sturgeon larvae. Life stages are based on Dettlaff, et al., (1993).
