“…Moreover, BUN level, which is a product of protein metabolism and an indicator of kidney and gills health, has significantly increased which may suggest kidney damage. On the other hand, in this study, variants with WGJ had a higher content of total protein, albumin, globulin, and Ca, which may suggest an immunological role of WGJ [47]. Our results are in agreement with Bao et al (2019) [47], who found an increase in the content of total protein, albumin and globulin in carp exposed to Aeromonas hydrophila infection after dietary administration of Gingko biloba leaf extract.…”

Wheat grass juice (WGJ) is an extract of young wheat plantlets (Triticum aetivum L.) used worldwide for its health related properties. In this study, the following feeds containing WGJ were tested on common carp (Cyprinus carpio L.): Control (C), WGJ1% (V1), WGJ2% (V2) and WGJ4% (V3) w/w. Fish with an average initial weight of 102 g/individual were grown in a recirculating aquaculture system. The results showed that WGJ had stimulatory effects on growth performance. Accordingly, final body weight increased by 11% at V1, 39% at V2 and 23% at V3, while other indices (feed conversion ratio, specific growth rate, relative growth rate, protein efficiency ratio, and condition factor) were unaffected. Body composition analyses revealed a significant decrease in fat content at V2 and a significant increase in collagen and ash at the same variant, while the protein content was unmodified. Regarding the blood profile, significant increases in the content of albumin, globulin, total protein, and calcium were recorded in the variants with WGJ. The positive results of WGJ on carp can be attributed to its biochemical composition, which is rich in chlorophyll (4.71 mg mL−1), total phenols (164 µg mL−1 gallic acid equivalents), and high antioxidant activity (67% inhibition of DPPH 2,2-diphenyl-1-picrylhydrazyl). The results suggest WGJ can be used as a promising feed additive for common carp.

“…The herbal medicinal products have been studied in humans, mice and other animals, and they have been used as feed additives for fishes. Some herbal medicinal products studied in carps have been reported, such as Ginkgo biloba leaf extract, Astragalus root and Chinese Angelica root (Bao et al, 2019; Bulfon et al, 2015; Jian, & Wu, 2004). The honey bee pollen was investigated to add in fish diets, such as Nile tilapia ( Oreochromis niloticus ) (El‐Asely et al, 2014; Picoli et al, 2019), rainbow trout ( Oncorhynchus mykiss ) (Torres Sánchez et al, 2020) and meagre ( Argyrosomus regius ) (Panettieri et al, 2020) and have led to improved growth and immune status.…”

A 6‐week feeding trial was conducted to investigate the effects of dietary supplementation with peony pollen on growth performance, intestinal function, fillet quality and fatty acids profiles of common carp. The results showed that supplementation of peony pollen significantly improved the growth performance. The textures of muscle in terms of hardness, springiness, cohesiveness, gumminess, chewiness and resilience were higher in peony pollen groups than control group. Dietary supplementation with peony pollen significantly improved the fold height, enterocyte height, microvillus height, intestinal wall thickness and intestinal crypt height of mid‐intestine from common carp in contrast to basal diet. Moreover, peony pollen could significantly increase digestive capacity observed in terms of an increase in lipase, amylase and trypsase activities. Peony pollen supplementation enhanced the antioxidant capacity via an increase in catalase, and total antioxidant capacity, accompanied by a significant reduction in malondialdehyde. Dietary supplementation with peony pollen may regulate lipid metabolism and fatty acids composition of common carp. Overall, the peony pollen could improve the fish health status by elevating immune responses and antioxidant capacity of intestine and system immunity. And the optimum concentration was recommend is 30 g peony pollen per kilogram feed. Further studies on the peony pollen practical approaches during culturing periods in the aquaculture industry are needed.

“…Until now, most research on formulating effective methods of disease prevention has focused on using chemotherapeutics (e.g. antibiotics) (Bao et al, 2019). However, out of concerns about health and the environment, the chemotherapeutics was now rarely used to control bacterial diseases in aquaculture industry (Abdel Rahman et al, 2019).…”

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.
