“…Muthuraman and co‐workers were postulated that the antioxidative effect of Zn may be related to mRNA expression of antioxidant enzyme (Muthuraman et al, 2014). Moreover, Huang and co‐workers found that increasing the organic Zn (2‐hydroxy‐4‐(methylthio) butyrate Zn) level in diet can significantly increase live catalase (CAT), T‐SOD and Cu‐Zn SOD activity of fish (Huang et al, 2018). Also, MDA content in sauvage ( Paramisgurnus dabryanus ) was obviously decreased with the increase of dietary Zn Methionine levels (Du et al, 2020).…”

“…Noteworthy, Zn not only as a cofactor for cytoplasm and extracellular SOD, but also plays an important role in gene regulation in lymphocytes (Sallam et al, 2020). Some studies started that Zn supplementation augmented the non‐specific innate immunological response (e.g., lysozyme activities) in Nile tilapia (Awad et al, 2019; Huang et al, 2018). Recent study also demonstrated that Nile tilapia fed with organic Zn (Zn Methionine) displayed significantly higher immune responses and resistance to bacterial infection than inorganic Zn treatment (Kishawy et al, 2020).…”

“…However, the use of dietary Zn supplements requires careful consideration of its chemical form (Awad et al, 2019). It was reported that the chemical form of minerals in feed diet is one of the important factors affecting the stability and bioavailability of minerals in fish (Huang et al, 2018). The high residue of Zn ions will be released into the environments if fish intake the low bioavailability Zn source, resulting in increasing the metal load of the aquatic system (Klinger & Naylor, 2012; Northey et al, 2017).…”

Zn is one of the essential elements to maintain normal fish metabolic process (including growth, development and reproduction), which have different chemical status in nature including inorganic, organic and nano‐sized. In this work, the efficacy of gluconic acid zinc (Glu‐Zn), nano zinc oxide (Nano ZnO), zinc sulphate (ZnSO4) on the growth performance, tissue mineral elements deposition, antioxidant activity and immune response of the tilapia fish Nile tilapia (Oreochromis niloticus) was evaluated. Three experimental diets were prepared by adding different forms of Zn sources (ZnSO4 as a control group) with same Zn concentration (40 mg/kg) and used to feed fish for 60 days. The biological trial results displayed that the growth performance of Nile tilapia has not obviously affected by different Zn form source supplement. However, Glu‐Zn and Nano ZnO supplements have significantly stimulated the Zn and Cu absorption deposition efficiency in the fish tissues as compared to ZnSO4 group. Besides, there was a significant increase in Cu‐Zn superoxide dismutase (35.03 U/mgprot), alkaline phosphatase (79.34 U/mgprot), aspartate aminotransferase (23.42 U/L), alanine aminotransferase (18.45 U/L), glutathione peroxidase (171.24 U/mgprot) and fatty acid synthase (11.55 ng/mL) content in Glu‐Zn treatment. Additionally, Glu‐Zn supply significantly increased serum lysozyme (9.91 U/mL), immunoglobulin M (0.48 g/L), complement 3 (0.74 g/L) and complement 4 (0.95 g/L) activity of Nile tilapia. Also, compared to ZnSO4 diet, lysozyme (11.44 U/mL) and complement 4 (0.63 g/L) content were obviously higher in fish fed Nano Zn diet. These findings revealed that supplementation with Glu‐Zn as a Zn source in feed is better than ZnSO4 for improving tissue mineralization, antioxidant stress, alleviate lipid peroxidation and immunity response of Nile tilapia. Meantime, Nano ZnO also played a positive role in the tissue mineralization and immunity response of Nile tilapia.

Synthesis and Efficacy of the N-carbamoyl-methionine Copper on the Growth Performance, Tissue Mineralization, Immunity, and Enzymatic Antioxidant Capacity of Nile tilapia (Oreochromis niloticus)

Immunogenic, methionine copper-induced response had proven to be precedent in providing resistance against certain diseases in fish. This study allocates the fitness strategy for Oreochromis niloticus by introducing and incorporating the well-designed, stabilized, and biocompatible N -carbamoyl-methionine copper (NCM-Cu) as a Cu potent source in diet that enhances the bioavailability and fitness. The synchronized NCM-Cu complex was characterized by directing ultraviolet and visible spectrophotometry (UV–vis), Fourier-transform infrared (FTIR), X-ray diffractometry (XRD), thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. Results revealed blue columnar crystalline, NCM-Cu complex with an empirical formula as C 12 H 30 CuN 4 O 10 S 2 . Anonymously, the overall growth performance of the fish remained unaltered with NCM-Cu adjunct feed. NCM-Cu significantly raised the Cu accumulation in the fish muscles, liver, gill, and intestine in contrast to the basic Cu-rich feed. The serum antioxidant enzyme activity elevated up to (ceruloplasmin: 19.38 U/L) and the lowest liver malondialdehyde (MDA) content (8.81 nmol/mg prot.) and triglyceride content (0.39 nmol/g prot.) were observed in the NCM-Cu group as compared to the basic Cu and CuSO 4 groups, suggesting that NCM-Cu promoted antioxidative responses and alleviated lipid peroxidation of O. niloticus . Overweening, the synthesized complex, NCM-Cu significantly regulated the expression levels of lysozyme, immunoglobulin M, complement 4, and complement 3 up to 10.93 U/mL, 0.72, 0.77, and 1.18 mg/mL in serum, respectively. Thus, such endorsed results reveal the preeminence of NCM-Cu-supplemented diet for the fitness in O. niloticus .

“…Biological availability of Fe measured by a hemoglobin regeneration assay in Atlantic salmon showed that the relative availability of Fe from ferric chloride, ferric oxide, blood meal and herring meal was 98.8, 17.8, 52.3 and 47.1%, respectively (Naser, 2000). However, higher bioavailability of iron from blood meal (Andersen et al, 1997), Fe-hydroxy methionine analogue (Huang et al, 2018) and Fe-methionine (Qiao et al, 2013) have been reported for Atlantic salmon, grouper and cobia respectively. The quality of blood meal varies widely in terms of protein quality.…”

Aquatic animals have unique physiological mechanisms to absorb and retain minerals from their diets and water. Research and development in the area of mineral nutrition of farmed fish and crustaceans have been relatively slow and major gaps exist in the knowledge of trace element requirements, physiological functions and bioavailability from feed ingredients. Quantitative dietary requirements have been reported for three macroelements (calcium, phosphorus and magnesium) and six trace minerals (zinc, iron, copper, manganese, iodine and selenium) for selected fish species. Mineral deficiency signs in fish include reduced bone mineralization, anorexia, lens cataracts (zinc), skeletal deformities (phosphorus, magnesium, zinc), fin erosion (copper, zinc), nephrocalcinosis (magnesium deficiency, selenium toxicity), thyroid hyperplasia (iodine), muscular dystrophy (selenium) and hypochromic microcytic anaemia (iron). An excessive intake of minerals from either diet or gill uptake causes toxicity and therefore a fine balance between mineral deficiency and toxicity is vital for aquatic organisms to maintain their homeostasis either through increased absorption or excretion. Release of minerals from uneaten or undigested feed and from urinary excretion can cause eutrophication of natural waters, which requires additional consideration in feed formulation. The current knowledge in mineral nutrition of fish is briefly reviewed.
