“…However, it was observed that Mn concentrations in several tissues of tilapia significantly increased with either Glu‐Zn or Nano ZnO diet when compared to ZnSO 4 diet, suggesting that Nano Zn and Glu‐Zn played a positive role in Mn accumulation in fish tissues. In previous studies, Zn and Mn interactions have been observed in gilthead seabream and cobia ( Rachycentron canadum ) (Domínguez et al, 2019; Nie et al, 2016), while the Zn was reduced with increasing dietary Mn in some fishes (Liu et al, 2018). However, there are also experiments reported that dietary Nano ZnO supplementation increased total body Mn concentration of marine medaka as compared to inorganic Zn (Jian Wang 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.

“…The pearl gentian grouper Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂ is a typical marine carnivorous fish, with fast growth rate, high market value, and high disease resistance. It is widely farmed in China and all over the world (Liu et al, 2018 ). Our previous research showed that high substitution levels of soy meal, such as SBM and FSBM, induced enteritis in the pearl gentian grouper.…”

Soy meals can cause intestinal inflammation and even injury in animals, especially infants and juvenile individuals. This study investigated the effects of fermented soybean meal (FSBM) on the growth and intestinal homeostasis of juvenile pearl gentian grouper and examined the mechanisms by which FSBM and soybean meal (SBM) induced enteritis in fish, using “3+2” full-length transcriptome sequencing. We randomly assigned 720 female juvenile groupers into three treatment groups: FM control group, 20% FSBM group (FSBM20), and FSBM40 group (n = 4). Three iso-nitrogenous (50% protein) and iso-lipidic (10% lipid) diets were prepared and fed to fish for 10 weeks. The water volume in each barrel was about 1 m3, using natural light and temperature. Results showed that dietary FSBM, at experimental level, significantly affected fish growth and intestinal structure negatively and significantly increased enteritis indices. The degree of intestinal injury and inflammation was determined by the enzyme activities of trypsin and lysozyme, and the contents of IgM, C3, C4, and malondialdehyde, and the expressions of pro-inflammatory genes (IL1β, IL8, IL17, and TNFα) and anti-inflammatory genes (IL4, IL10, and TGFβ1). Full-length transcriptome analysis identified 2,305 and 3,462 differentially expressed genes (DEGs) in SBM40 and FSBM40 groups, respectively. However, only 18.98% (920/5,445) of DEGs had similar expression patterns, indicating that high levels of SBM40 and FSBM40 have different metabolic strategies. KEGG enrichment analysis indicated that among the significant pathways, ~45% were related to immune diseases/systems, infectious diseases, and signal transduction in both SBM and FSBM groups. Based on PacBio SMRT sequencing, nine toll-like receptor (TLR) members, including TLR1, TLR2, TLR3, TLR5, TLR8, TLR9, TLR13, TLR21, and TLR22, were detected in intestinal tissues of pearl gentian grouper. TLR-MyD88-NF-κB signaling pathway played an important role in the development of FSBM- and SBM-induced enteritis in pearl gentian grouper; however, TLR receptors used in SBM and FSBM groups were different. TLR1, TLR8, TLR13, and TLR22 were the main receptors used in FSBM group, while TLR5, TLR8, TLR9, TLR21, and TLR22 were the main receptors used in SBM group. Present study provides valuable theoretical references for further research on soy protein-induced enteritis in fish.

“…According to the methods of Zhai et al (2016), the activities of amylase, lipase and protease in the intestine were analyzed by UV-Vis spectrophotometer (UV-1200, Shanghai Mipoda Instrument Co., Ltd., China). The malondialdehyde (MDA) level, total antioxidant capacity (T-AOC) activity, superoxide dismutase (SOD) activity, catalase (CAT) activity, and glutathione peroxidase (GSH-Px) activity were tested by Multifunctional Microplate Reader (TECAN Infinite 200 PRO, Tecan Austria GmbH, Austria) with commercial kits according to the descriptions of Zhai et al (2016;2018). The level of MDA was expressed as nmol/mg protein.…”

The present study was conducted to evaluate whether grape seed proanthocyanidins (GSPs) could alleviate the negative effects of dietary cadmium on growth performance, body composition, activities of digestive enzymes, and antioxidant potential in the intestine of pearl gentian grouper (Epinephelus fuscoguttatus female x Epinephelus lanceolatus male). Two hundred and forty pearl gentian groupers with the initial average body weight of 31.30±0.05 g/fish were randomly divided into four treatment groups with three replicates in each group and 20 fish in each replicate. The four treatment groups were identified as control group (the basal diet), Cd group (the basal diet+300 mg/kg Cd), Cd+GSPs group I (the basal diet+300 mg/kg Cd+400 mg/kg GSPs), and Cd+GSPs group II (the basal diet+300 mg/kg Cd+800 mg/kg GSPs group), respectively. The trial lasted for 42 days. Fish exposed to 300 mg/kg dietary cadmium had lower growth performance, mineral metabolism disorders with lower calcium and phosphorus levels, higher ash level, decreased lipase and protease activities, and antioxidant potential in the intestine. Dietary GSPs supplementation could counteract those negative effects to a certain extent. The alleviation effects of Cd+GSPs group II were better than those of Cd+GSPs group I. Except for calcium and phosphorus levels in whole fish composition, 800 mg/kg dietary GSPs supplementation could not recover the adverse effects caused by Cd stress. These results suggested that GSPs might potentially mediate dietary cadmium toxicity and alleviate the negative effects on pearl gentian grouper.The IJA is a peer-reviewed open-access, electronic journal, freely available without charge to users -Produced by the AquacultureHub non-profit Foundation Sale of IJA papers is strictly forbidden
