“…Findings of the present study revealed that serum total protein in fish fed on the diet supplemented with 6% SIM was significantly higher than the control suggesting better humoral homoeostasis in this group. Similarly, total protein content in serum increased in different fish species fed seaweeds or their extracts such as sutchi catfish fed fucoidan‐rich seaweed extract (Prabu et al., 2016), olive flounder fed on the Pyropia yezoensis extract (Choi, Kim, Han, Nam, & Lee, 2014), L. calcarifer fed G. pulvinata (Morshedi et al., 2018), rohu carp ( Labeo rohita ) fed on S. wightii or its fucoidan‐rich extract (Gora et al., 2018) and rainbow trout fed S. angustifolium hot water extract (Zeraatpisheh, Firouzbakhsh, & Khalili, 2018).…”

A 6‐week study was conducted to assess the effect of dietary fishmeal (FM) replacement with Sargassum ilicifolium meal (SIM) at four substitution levels including 0 (control), 3% (S3), 6% (S6) and 9% (S9) on performance of Asian sea bass (Lates calcarifer) juveniles (initial mean body weight of 29.0 ± 1.0 g). Growth performance pronouncedly increased in SIM‐supplemented groups compared to the control (p < .05). Fish fed on the S6 diet had higher pancreatic digestive enzyme activities than other treatments. Supplementing diet with SIM remarkably enhanced red blood cell count compared to the control. Moreover, fish in the control and S3 groups had higher lymphocyte, but lower neutrophil percentages than the S6 and S9 treatments (p < .05). The greatest and the least amounts of the total protein and total immunoglobulins (Ig) in serum were found in the S6 and the control, respectively. The amount of alternative complement pathway activity in the serum of fish in the S9 group was higher than the other groups, whereas higher serum lysozyme activity was found in the S6 and S9 treatments compared to those in the control and S3 groups (p < .05). Total Ig content of the skin mucus in the S6 and S9 groups was higher than the control. The greatest and the least mucosal lysozyme activates were found in the S6 and control, respectively (p < .05). The liver superoxide dismutase activity in the S6 and S9 groups was higher than the other treatments (p < .05). The insulin‐like growth factor‐1 mRNA transcript abundance levels in the liver were greatest and the least in fish fed on the S9 and control, respectively. The expression of lysozyme gene, as indicated by an abundance of mRNA transcript for lysozyme, in the liver was higher in the S6 and S9 groups than the other groups (p < .05). Furthermore, fish fed the SIM‐incorporated diets had higher interlukine‐1β mRNA transcript abundance in the liver compared to the control (p < .05). Overall, according to the findings of this study 6% of dietary FM could be replaced with SIM to improve growth rate and health status in L. calcarifer juveniles.

“…The flavonoids and phenolic acids in moringa leaf powder have been well proven to exhibit immune modulation properties (Evans, 1994). In contrast, the positive effects of many plant extracts such ginger ( Zingiber officinale ) (Haghighi & Rohani, 2013), stachys Vahl ( Stachys lavandulifolia ) (Moghanlou, Isfahani, Dorafshan, Tukmechi, & Aramli, 2018), macroalga ( Sargassum angustifolium ) (Zeraatpisheh, Firouzbakhsh, & Khalili, 2018), black cumin seed oil ( Nigella sativa ) and nettle extract ( Quercetin ) (Awad, Austin, & Lyndon, 2013), elephant's foot ( Elephantopus scaber ) (Doan, Hoseinifar, Sringarm, Jaturasitha, Khamlor, et al, 2019), assam tea ( Camellia sinensis ) (Doan, Hoseinifar, Sringarm, Jaturasitha, Yuangsoi, et al, 2019), fermented moringa ( M. oleifera ) (Zhang et al., 2020) and moringa ( M. oleifera ) (Mansour et al., 2020) have shown immune response improvement in fish.…”

Effect of Moringa oleifera leaf powder on skin mucosal immune responses and growth performance of guppy, Poecilia reticulata (Peter, 1860)

The present study was carried out to evaluate the effects of moringa leaf powder through dietary supplementation in guppy fish (Poecilia reticulata) on skin immune responses and growth performance. A total number of 240 fish (average body weight of 0.13 ± 0.01 g) were equally divided into four feeding groups including 0% (T0), 5% (MT1), 10% (MT2) and 15% (MT3) concentration of moringa leaf powder. The results showed that levels of lysozyme activity and alternative complement activity (ACH50) significantly increased with increase the moringa leaf powder (p < .05) concentration. Regarding the myeloperoxidase activity results, 15% doses of moringa leaf powder showed the highest amount of myeloperoxidase activity as compared to control group (p < .05). Total immunoglobulin content was increased significantly 10% and 15% treatments as well. In the present investigation, dietary supplementation of Moringa oleifera leaf powder had no significant impact on weight gain, net weight gain, specific growth rate, FCR and survival rate. The present results concluded that a dietary dose of 15% moringa leaf powder per kg of feed can significantly improve skin mucus immunity through enhanced production of mucus in the guppy.

“…extract (Peixoto et al 2016b), although notably only half the effect of whole seaweeds (+47% compared with the unsupplemented control). The lowest value for that category (−32% compared with the unsupplemented control; negative outlier) was the result of feeding rainbow trout a diet supplemented with 0.01% of the brown seaweed Sargassum angustifolium (Zeraatpisheh et al 2018). The highest increase in haemolytic activity, and the greatest improvement for any innate parameter quantified, was a 901% enhancement compared with the unsupplemented control (Fig.…”

“…In some instances, the reduced activity of the immune parameters led to significant increase in disease resistance. For example, a reduction in haemolytic activity of 20% for rainbow trout fed a hot water extract from Sargassum angustifolium (a brown seaweed) still yielded a 42% increase in survival when exposed to Yersinia rukeri (Zeraatpisheh et al 2018). In comparison, Satoh et al (1987) reported a doubling in the phagocytic activity (+97%) of sea bream fed the green seaweed Ulva sp.…”

“…lysozyme activity and respiratory burst), they contributed more than one data point to the meta‐analysis. For example, Zeraatpisheh et al (2018) tested four dose levels of a particular seaweed extract and investigated their effects on two immune response parameters (lysozyme activity and haemolytic activity; ACH50) before and after pathogen exposure. As a result, this study contributed 12 data points to the meta‐analysis: lysozyme ( n = 4) and ACH50 ( n = 4) before the pathogen challenge and the percentage survival of each treatment after the challenge ( n = 4).…”

Reviews in Aquaculture

Disease is an enduring threat to aquaculture, with direct costs from outbreaks of more than US$6 billion a year. Efforts to reduce antibiotic use in aquaculture have resulted in a recent shift towards the use of immunostimulants that boost fish immune systems. Seaweeds are a potential source of unique immunostimulants because of their diverse taxonomy (11,353 species) and diverse bioactives, but there has been no synthesis of their effects on fish. A systematic review and meta‐analysis of 142 peer‐reviewed studies was conducted to evaluate the effects of seaweed on the innate immunity, resistance (to stress and pathogens) and growth of farmed fish. Overall, our review indicated that dietary supplementation with seaweeds or their extracts had substantial positive impacts on the health and growth of fish compared with control groups and were comparable to currently utilised immunostimulants. Dramatic effects on survival of fish during challenge experiments were detected, with an average of 33% higher survival of fish fed diets that included seaweeds or their extracts. This study provides broad evidence for the benefits of supplementing fish feed with the reviewed seaweeds or their bioactive extracts, including potential synergistic effects of supplements. However, the meta‐analysis also highlighted considerable variation among studies, and between fish and seaweed species, making it difficult to extrapolate results beyond individual experiments. Future studies should focus on developing synergistic combinations of ingredients and elucidating the mode of action through isolation of seaweed bioactives, together with standardisation of experimental conditions, to fast‐track the benefits of seaweed supplements for aquaculture.
