“…Despite extensive researches on different metabolic pathways, there is little information about the effect of dietary Zn on erythrocytes synthesis in fish. Zn is one of the essential elements affecting the protein synthesis in the erythrocytes, such as carbonic anhydrase and superoxide dismutase required for proper function of red blood cells (Hsieh et al 2013;Hansch and Mendel 2009;Huang et al 2015), which could explain the higher erythrocytes number of the fish fed diets with higher level of supplemental Zn in the present study. Zn also plays an important role in hemoglobin synthesis by activating D-aminolevulinic acid (ALA) dehydrogenase, an enzyme essential for the porphobilinogen formation from two ALA molecules.…”

“…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).…”

This study investigated the effect of dietary Zn levels on growth performance, feed utilization, and hematological parameters of juvenile Siberian sturgeon (Acipenser baerii, Brandt 1869). The five semipurified diets were formulated by adding 0, 5, 10, 20, and 40 mg Zn kg -1 diet in the form of zinc sulfate (ZnSO 4 ) to provide the actual dietary value of 14.7, 20.8, 27.3, 37.7, and 46.4 Zn kg -1 diet, respectively. The results showed that dietary Zn elevating level significantly improved the growth and feed utilization of the fish (p \ 0.05), but not the hepatosomatic index (p [ 0.05). Erythrocyte number, hemoglobin concentration, and hematocrit were increased with raising dietary Zn level (p \ 0.05), whereas a regular trend was not observed in blood indices, including MCV, MCH, and MCHC. A significant increase was also found in the leucocyte number followed by their differential counts, except for eosinophil percentage. The broken line regression model indicated optimal dietary Zn level for growth maximization of fish was estimated to be 29.15 mg Zn kg -1 diet. In spite of well correlation with dietary Zn level, no break point was observed to estimate the juvenile Siberian sturgeon requirement based on the erythrocyte numbers.

“…The dose–response of dietary Zn were founded in many other fish species, such as C. carpio var. Jian (Feng et al, ), O. mykiss (Hidalgo, Expósito, Palma, & Higuera, ), Nile tilapia Oreochromis niloticus (Huang et al, ) and many other fish species (Chen, Cheng, Hu, & Chen, ; Jiang et al, ). These results demonstrated that optimal dietary Zn supplementation can improve the growth performance and antioxidant responses of fish.…”

“…Thus, Zn is considered as an essential nutrient in freshwater fish feed. At present, there have been many reports on dietary Zn requirement of fish, and the optimal dietary Zn requirement varies from 10 mg/kg to more than 100 mg/kg among different fish species (Huang et al, ; Jiang et al, ; Luo, Tan, Zheng, Chen, & Liu, ; Welker, Barrows, Overtruf, Gaylord, & Sealey, ).…”

This study was conducted to assess the dietary zinc (Zn) on growth and antioxidant capacity of adult Paramisgurnus dabryanus. Zinc methionine (ZnM) of grade levels (0, 20, 40, 80, 120 and 160 mg/kg diet respectively) was supplemented, providing actual dietary Zn concentrations of 24.38, 28.03, 31.68, 38.98, 46.28 and 53.58 mg/kg diet respectively. P. dabryanus with an initial body weight of 5.21 ± 0.15 g were fed these Zn supplemented diets for 8 weeks. Results showed that the weight gain (WG) and specific growth rate (SGR) increased with increasing dietary Zn levels from 24.38 to 31.68 mg/kg, and then decreased above these levels. The hepatopancreas index (HIS) was the highest at 31.68 mg/kg, followed by 38.98 mg/kg. The enzymatic antioxidants in plasma and hepatopancreas firstly increased, and reached the peak at 31.68 or 38.98 mg/kg, then kept stable with the increase of dietary Zn levels. On the contrary, the content of MDA firstly decreased, and then increased. According to WG and T‐AOC in plasma, the Zn requirement was determined to be 32.02 and 32.24 mg/kg, respectively, based on regression analysis. The relatively low dietary Zn requirement of P. dabryanus may involve in the evolutional adaption of metal absorption and utilization to their habitat.

An 80‐day trial was carried out to evaluate the effects of replacing dietary inorganic trace minerals (ITM), with metal‐amino acid complexes (MAAC) on immune response, antioxidant capacity, and expression of cytokines genes of Nile tilapia (Oreochromis niloticus) reared in in‐pond hapas under field conditions. Quadruplicate groups of fish (93.65± 1.05 g average initial body weight ± SE) were stocked in 2‐m3 hapas fixed in a fish pond, at a density of 30 fish m‐3 (60 fish per hapa). Five isocaloric (17 MJ kg‐1), isonitrogenous (30% CP) extruded tilapia diets were produced, containing 0 (control), 25%, 50%, 75%, and 100% MAAC (Zn, Se, Cu, Fe, and Mn) as a replacement of the inorganic mineral premix. Replacement of ITM with MAAC premix enhanced the immune and antioxidant responses of Nile tilapia. The activities of lysozyme (LSZ) (96.71 U ml‐1 ± 0.69 – 120.83±1.43 U ml‐1), respiratory burst (0.54±0.08 mg ml‐1 – 3.61±0.20 mg ml‐1), alternative complement (ACH50) (34.49±56.96 % hem ml‐1– 56.96±0.79 % hem ml‐1), phagocytic cells (PA) (5.30±0.52% – 17.27±0.82%), phenoloxidase (PO) (34.96±0.96% – 54.68±0.92%), superoxide dismutase (SOD) (45.15±0.88% – 65.92±0.85%), glutathione peroxidase (GPx) (0.22±0.01 nM min‐1 mg‐1 – 1.94±0.09 nM min‐1 mg‐1), and liver function enzymes were all significantly improved (P<0.01, except for PA and GPx where P<0.05) with increasing supplemental MAAC up to 50% substitution level and decreased with further increase in MAAC to 75% and 100% levels. The expression of cytokine genes (mRNA abundance), including interferon (IFN‐γ) (2.67±0.03 – 4.62±0.08), tumor necrosis factor (TNF‐α) (2.96±0.05 – 6.73±0.05), serum alkaline phosphatase (AKP) (0.51±0.02 – 1.72±0.02), the integrated microbial genomes (IgM‐2) (22.51±0.36 ‐ 38.48±0.03) and transforming growth factor (TGF‐β) (1.84±0.02 – 7.76±0.02) genes was significantly upregulated in fish fed on MAAC–supplemented diets (P<0.05) compared with the control group. The 50% MAAC level produced the highest upregulation of these genes, whereas gene expression decreased with increasing dietary MAAC levels to 75% and 100%.
