“…However, in the present study, weight gain was not improved by dietary β-glucan in tilapia in brackish water. In O. mossambicus, only 1% β-glucan in the diet significantly increased weight gain after an 8-week cultivation [42]. Similar results were also found in Dicentrachus labrax [43], O. nilotics [44], and Carassius auratus by adding β-glucan [45].…”

Long-term exposure to hyperosmotic environments can induce severe immune damage and increase risk in tilapia breeding. As an effective immunoregulator, β-glucan has attracted extensive attention in nutritional research and given rise to high expectations of improving health status and alleviating organismal damage in tilapia, Oreochromis niloticus, in brackish water. In this study, an 8-week cultivation experiment was conducted on tilapia fed a basal diet or diets with β-glucan supplementation in freshwater (control) and brackish water. Growth performance, hematological aspects, immune cytokine expression, and the intestinal microbiota of tilapia were analyzed. The results indicated that supplementation with β-glucan significantly reduced the enlarged spleen of tilapia resulting from hypersaline stress. Tilapia fed β-glucan showed significantly-greater decreases in the red blood cell count, hematocrit, red cell distribution width, platelet count, and plateletcrit than those fed the basal diet. β-glucan significantly decreased the high expression of immune-related genes in the spleen induced by hyperosmotic stress. In the intestine, the high migration inhibitory factor-2 (MIF-2) and IL-1β gene expression induced by hypersaline stress was significantly reduced. β-glucan supplementation also significantly increased the abundance of beneficial microbiota such as Lactobacillus, Phycicoccus, and Rikenellaceae. Therefore, dietary β-glucan supplementation can significantly reduce spleen enlargement and improve immune function in tilapia in brackish water. β-glucan intake can also optimize the intestinal microbiota of tilapia in brackish water and improve fish health.

“…Also, in Oreochromis mossambicus , dietary supplementation of β‐glucan (10 mg g −1 for eight weeks) enhanced ammonia (100 mg L −1 for 1 week) stress tolerance (Divya et al . 2020) as previously reported in Japanese sea bass (ChunYu et al . 2013).…”

Over the last few decades, the demand-driven growth in aquaculture has been tremendous due to development and adoption of cutting-edge technologies and production systems such as intensification and high input aquaculture. This growth, however, has witnessed an insurgence of various environmental and husbandry-related stressors posing major challenges to the aquaculture sector limiting its further expansion worldwide. These stressful conditions impair the health of cultured animals and predispose them to diseases resulting in economic losses. Hence, optimizing the stress resilience of the cultured species is paramount to ensure sustainable development of aquaculture sector. Addressing the concerns of stress mitigation in aquaculture, a plethora of research investigations have been intensively carried out all over the world targeting the management of cultured environment as well as cultured species. Among various mitigation strategies, dietary interventions appear to be pliable and a sustainable approach to develop immunocompetence and stress resistance in fish as requirement of several nutrients may increase under stressful conditions. The suboptimal and/or excessive levels of several essential and non-essential nutrients modulate the immune response and stress/disease resistance. Hence, the present review is an inclusive and informative compilation of dietary interventions for management of stress in aquaculture. This review highlights the stress-mitigating roles of different nutritive and non-nutritive compounds/additives such as amino acids, essential fatty acids, phospholipids, vitamins, minerals, carotenoids, different synthetic chemicals and biological derivatives from bacteria, yeast, fungi, algae, plants and animals as a promising stress management strategy to enhance the overall performance of the cultured species.

“…Environmental stress caused by either overcrowding or by environmental pollution, is one of the problems the current aquaculture suffers from. Food supplementation with β-glucan was found to improve ammonia-related stress in Oreochromis mossambicus via improvements of cellular, humoral, and antioxidant response [215].…”

Administration of β-glucans through various routes, including immersion, dietary inclusion, or injection, have been found to stimulate various facets of immune responses, such as resistance to infections and resistance to environmental stress. β-Glucans used as an immunomodulatory food supplement have been found beneficial in eliciting immunity in commercial aquaculture. Despite extensive research involving more than 3000 published studies, knowledge of the receptors involved in recognition of β-glucans, their downstream signaling, and overall mechanisms of action is still lacking. The aim of this review is to summarize and discuss what is currently known about of the use of β-glucans in fish.
