“…The results are comparable with those of Mahgoub et al [ 25 ], who illustrated that Nile tilapia fed fucoidan had enhanced growth performance and feed utilization. Additionally, the inclusion of fucoidan in the diets of red sea bream ( Pagrus major ) [ 40 ], gibel carp ( Carassius auratus ) [ 41 ], and Labeo rohita [ 26 ] enhanced the growth performance. The enhanced growth performance is possibly attributed to the high feed utilization in Nile tilapia delivered fucoidan for 30 days.…”

“…Seaweed-derived polysaccharides such as fucoidan are active substances with immunostimulant and growth-promoting activity [ 22 , 23 ]. In this context, dietary inclusion of fucoidan resulted in enhancing the growth performance, feed utilization, immunity, antioxidative response, and resistance against infection with bacterial and viral invaders in finfish species [ 24 , 25 , 26 ]. Fucoidan has a sufficient amount of l-fructose and sulfate ester groups known as influential immunomodulatory factors [ 27 ].…”

Waterborne herbicides are stressful agents that threaten the productivity and safety of finfish species. In this study, the toxicity impacts of atrazine (ATZ) and the protective role of fucoidan were investigated on the health performance of Nile tilapia. For 40 days, the total number of 180 Nile tilapia was assigned in four groups (triplicates, 15 fish/replicate), where the first (control) and third groups were offered the control diet, while the second and fourth groups were offered a fucoidan (FCN). Further, in the third and fourth groups, the water was mixed with atrazine (ATZ) at 1.39 mg/L daily. The growth rate, FCR, and survival rate were markedly enhanced by fucoidan but severely declined by ATZ exposure (p < 0.05). The morphological structure of the intestine in the control fish revealed normal structure, while fucoidan-treated groups showed eminent enhancement and branching of the intestinal villi. The intestine of ATZ-treated fish revealed deterioration and the intestinal mucosa, inflammatory cell infiltration, and separation of lining epithelium. The highest Hb, PCV, RBCs, WBCs, total protein, and albumin were observed in Nile tilapia fed fucoidan, but the worst values were seen in ATZ-intoxicated fish (p < 0.05). The liver-related enzymes (ALT and AST) and kidney function (urea and creatinine) showed impaired values by ATZ toxicity and were regulated by dietary fucoidan. Meanwhile, fish fed fucoidan and exposed to ATZ had lower total cholesterol and triglyceride values than fish exposed to ATZ without fucoidan feeding (p < 0.05). The SOD, CAT, GPx, cortisol, and glucose levels were increased in ATZ-exposed fish and reduced by fucoidan (p < 0.05). However, the level of malondialdehyde (MDA) was reduced in fucoidan-fed fish and increased in ATZ-exposed fish (p < 0.05). Altogether, dietary fucoidan is required in fish diets to alleviate the impacts of ATZ-induced toxicity.

“…Phagocytic action can produce superoxide anions and their reactive derivatives during the intense oxygen consumption period (respiratory burst), which are toxic for fish pathogens (Hardie et al., 1996; Sharp & Secombes, 1993). Fish phagocytic cells (macrophages and neutrophils) can be stimulated through dietary immunostimulants like plant products (Fawole et al., 2016; Mir et al., 2017; Sahu et al., 2007; Yin et al., 2006). In our study, H. cordata leaf extract and leaf meal supplemented diets have improved the non‐specific defence mechanism in terms of significantly higher respiratory burst activity compared with control with best result found in fish fed 10 g/kg dietary leaf extract.…”

Intensified aquaculture is highly susceptible to stress and diseases that leading to decreased production. But, intensification of culture is necessary to meet the world's increasing protein demand as capture fisheries fail to do so in future. Therefore, there are challenges to make the intensified aquaculture sustainable. However, several attempts have been made to mitigate the stress and disease outbreak in intensified aquaculture system (Sakai, 1999; Chinabut & Puttinawarat 2005; Jadhav et al., 2006). Once, antibiotics were deliberated as an onetime cure to all disease problems in aquaculture. But, use of antibiotics is no more a sustainable option to avoid bacterial infections or be used as growth promoter as it leads to development of the antibiotic resistant bacteria along with its residues in the environment and fish

“…131 Studies governing its usage after extraction from the seaweed Sargassum wightii have increasingly focussed on its phagocytic and radical scavenging activity in L. rohita. 5 Fucoidan has been widely addressed to enhance immune parameters in fishes through antioxidant and radical scavenging activity, which increases synergistically with the degree of sulphation. 132 This has been supported by a study on L. rohita fingerlings which reported its synergistic supplementation, at higher level, with lower dosage of methionine, to be effective.…”

Dietary supplementation is an effective strategy for boosting the innate immune response in fishes. It involves the use of functional ingredients that bear the potential for mitigating the deleterious effects of chemotherapeutics (bioaccumulation and development of drug-resistant pathogens), as a more ecologically responsible approach to fish farming. With the emergence of probiotics, prebiotics, synbiotics and herbal immunostimulants; dietary supplementation has become an integral aspect of immunonutrition. In this review, we have compiled a list of dietary immunostimulants in rohu, based on the research carried over the last ten years. It should be noted that nearly 25% of the studies on dietary supplementation in Labeo rohita investigated probiotics species (either singly or as mixtures), followed by the use of herbal supplements or phytobiotics. In relation to stress, about 30% of the studies dealt with the supplementation of tryptophan, followed by the incorporation of lipotropes. Moreover, approximately 55-60% of the studies reviewed, were restricted to nutrition-based disease resistance against Aeromonas hydrophila infection. Commercially available probiotics and herbal feed additives have been helpful in the health management of L. rohita to some extent. Ongoing research is consistently exploring novel ingredients inducing favourable immunomodulation to survive stress and widespread A. hydrophila infection in L. rohita. However, further investigations aiming at broad-spectrum disease resistance and multiple stress resilience are recommended. Efforts must also be directed towards the elucidation of specifically targeted response in vivo. Overall, greater insights into the molecular mechanisms of dietary supplementation of immunostimulants warrants the use of downstream analytical techniques and highthroughput screening tools.
