Biology and Culture of Sturgeon Acipenseriformes

Effect of feeding strategy and carbohydrate source on carbohydrate utilization by white sturgeon (Acipenser transmontanus) and hybrid tilapia (Oreochromis niloticus X O. aureus)

“…The better carbohydrate utilization by sturgeon than tilapia may be related to the difference between their natural diets. One of the major natural food organisms for white sturgeon is mollusc (Moyle, 1976;Doroshov, 1985) which contains some glycogen whereas the major natural foods for tilapia are microorganisms, zooplankton and detritus (Bowen, 1982) which contain little digestible carbohydrate.…”

Missouri River Scaphirhynchus albus (pallid sturgeon) effects analysis—Integrative report 2016

“…Evidence from other sturgeon species and developmental theory supports the idea that food availability can be critical and may be limiting at the transition from free embryo to exogenously feeding larvae (Doroshov, 1985;Gisbert and Doroshov, 2003). Diet studies on pallid sturgeon document that first foods are generally Chironomidae or Ephemeroptera (Chipps and others, 2008;Andvik and others, 2010;Spindler and others, 2012;French, Graeb, Bertrand, and others, 2013;Harrison and others, 2014).…”

Effects of feed restriction on the upper temperature tolerance and heat shock response in juvenile green and white sturgeon

“…Such the relationship was not detected in either green sturgeon or white sturgeon (data not shown). Lastly, as a truly anadromous species, green sturgeon may have greater energy demands during juvenile development than the semi-anadromous white sturgeon (Doroshov, 1985;Moyle, 2002). Green sturgeon used in the current study were at the size previously shown to undergo the necessary physiological transformations to prepare for migration to full-strength seawater (Allen et al, 2011), and this likely leads to relatively high energy expenditures for basal maintenance (i.e., reduction in the aerobic scope) compared to white sturgeon Lee et al, 2015).…”
