Dietary zinc requirement of juvenile grass carp (Ctenopharyngodon idella) based on growth and mineralization

Dietary zinc requirement of Siberian sturgeon (Acipenser baerii, Brandt 1869) juveniles, based on the growth performance and blood parameters

“…Although the normal ranges for biochemical key parameters have been identified for various raised fish species (Kopp et al 2009;Xiaoyun et al 2009;Satheeshkumar et al 2011;Liang et al 2012), there is scare information about the blood characteristics in Siberian sturgeon especially under culture conditions. Results of the present study illustrated that supplemental dietary Zn improves the hematological parameters of Siberian sturgeon.…”

“…Zinc also serves as a functional cofactor for more than 200 metalloenzymes, such as superoxide dismutase, RNA polymerase, alkaline phosphatase, alcohol dehydrogenase, and carbonic anhydrase (Kucukbay et al 2006;Fountoulaki et al 2010;Luo et al 2011;Liang et al 2012;Lin et al 2013). The importance of Zn in the antioxidant protection has been also illustrated in many aquatic organisms (Huang et al 2015;Feng et al 2011;Trevisan et al 2014).…”

“…Jian carp , and 55.1 mg kg -1 diet for juvenile grass carp, Ctenopharyngodon idella (Liang et al 2012). Most of these recommendations have been established based on the growth performance, feed utilization, tissue concentration, and enzymatic activities.…”

Zinc Oxide, Zinc Sulfate and Zinc Oxide Nanoparticles as Source of Dietary Zinc: Comparative Effects on Growth and Hematological Indices of Juvenile Grass Carp (Ctenopharyngodon idella)

“…Conversely, deficiency of dietary Zn has been found to impair immunological responses in rainbow trout (Kiron et al, 1993) and depressed growth in catfish by reducing appetite and decreasing the levels of Zn and calcium in bones (Lim et al, 1996). Thus, normal level of Zn is important for normal physiology, growth, efficient food utilization and bone mineralization of fish, while excessive amount not only caused severe excretion of Zn but also showed negative effect on bone mineralization (Liang et al, 2012).…”

“…Besides these, it is an integral part of about 20 different metalloenzymes, like alcohol dehydrogenase, alkaline phosphatase and carbonic anhydrase (Tan and Mai, 2001). The retardation of bone growth due to deficiency of Zn also proves its importance in the growth and mineralization of bone tissues (Liang et al, 2012).…”
