“…Studies documented the protective effects of Chlorella vulgaris against arsenic and pesticide toxicity in Nile tilapia (Zahran & Risha 2014;Abdelhamid et al 2020;Zahran et al 2020), hypoxia and ammonia stress in Pacific white shrimp (Pakravan et al 2018) via improving antioxidant and immune responses. Similar reports have been made with other species such as Nile tilapia and common carp fed with Spirulina (Arthrospira platensis) when exposed to pesticide (Abdelkhalek et al 2015;Toughan et al 2018), gilthead seabream subjected to air exposure stress (de Mattos et al 2019), barramundi after transportation stress (Van Vo et al 2020) or Pacific white shrimp immersed in hot water extract of Spirulina when exposed to pH stress (Lin et al 2010). In recent studies, feeding of green algae Haematococcus pluvialis (at 0.3-0.6%) improved antioxidant capacity under acute hypoxia stress in golden pompano (Xie et al 2020) and low salinity tolerance in Pacific white shrimp larvae (Xie et al 2018).…”

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.

“…This dietary group also showed distinct fatty liver with intense vacuoles in the hepatocytes, necrosis and myodegeneration in muscle and a decrease in villous width, microvilli height and goblet cells density. The intestinal micomorphology, in particular, villous width, microvilli height and goblet cells density is related to absorptive surface area of intestine that have been reported to have correlation with digestion and absorption 38,40 . Such changes in the intestinal micromorphology might have induced the depressed growth of fish fed FM0.…”

The search for suitable fish meal replacements in aqua-diets is a salient agenda in the constant effort of making aquaculture practices more sustainable. In this study, we tested four customised diets composed by systematic inclusion of pre-selected fish meal substitutes, lupin kernel meal, BSF meal, TH and PBM on growth, metabolism, cytokine profile, gut morphology and microbiota of juvenile Lates calcarifer. Five isoproteic and isoenergetic diets were prepared viz. FM100 as a control (without fish meal substitute), while FM75, FM50, FM25 and FM0 indicates replacement of fish meal (FM) at 25%, 50%, 75%, and 100%, respectively by a mixture of four different pre-selected non-fish meal (NFM) ingredients. Fish fed FM100, FM75, FM50, FM25 exhibited consistent growth and haematological response, while the fish fed no fishmeal (FM0) showed significant decline in final body weight (FBW) and specific growth rate (SGR). The poor growth performance was correlated with a decrease in villous width, microvilli height and goblet cells density. A significant shift in abundance profile of Psychrobacter in the gut microbial profile of fish fed FM50 was noticed compared to fish fed FM100. The results of qRT-PCR showed up-regulated expression of innate immune responsive genes in the FM50 group. The adverse impacts on growth performance and gut health of fish fed FM0 suggest that the complete substitution of fishmeal is not advisable and the inclusion range of these alternatives should be decided for a species only after examining their effect on maximal physiological performance.

“…Barramundi has good meat quality, ability to tolerate a wide range of salinity, and ability to adapt to the versatile farming environment [ 7 ]. It is popularly cultivated both in freshwater and seawater in Malaysia, Thailand, Taiwan, Indonesia, Saudi Arabia, and Australia, contributing USD 320 million globally [ 8 , 9 ]. In Australia, barramundi farming is heavily dependent on imported FM resulting in incurring around 40% diet related cost which is the main impediment to increase the profitability [ 10 ].…”

The present study investigates if the total replacement of dietary fishmeal (FM) with poultry by-product meal (PBM), supplemented with methionine influences the muscle fatty acids composition, normal gut morphology, histological traits of the liver, muscle, and gill, liver enzymes, immune and antioxidant response, and stress-related gene in juvenile barramundi, Lates calcarifer in relation to growth and feed utilization. Barramundi (3.58±0.01g) were randomly distributed into six 300 L seawater recirculating tanks (25 fish/tank) and fed two formulated isonitrogenous and isolipidic diets for 6 weeks. The control diet had FM as the sole animal protein source, whereas other test diet had only PBM as an animal protein source. Dietary PBM affected the fish performance and feed utilization. Regarding muscle fatty acid profile, total saturated fatty acids and monounsaturated fatty acids elevated while total PUFA particularly n-3 LC-PUFA and EPA decreased in PBM fed fish than control diet fed fish. Liver, muscle, gill, and intestinal histology showed no obvious alteration in control diet fed fish, however, more lipid droplets and hepatic vacuolization in the liver, necrotic myotome in muscle, hyperplasia in secondary lamellae in gill and short and broken folds in the intestine were observed in PBM fed fish. Similar to light microscopy observation of intestinal morphology, the transmission electron microscopy (TEM) analysis revealed shorter and smaller microvilli in fish fed PBM. Histopathological alterations in the liver of PBM fed fish were further associated with the elevated levels of aspartate aminotransferase (AST) and glutamate dehydrogenase (GLDH) and the significant upregulation of stress-related genes, HSP70 and HSP90. Also, a negative influence on lysozyme activity, and antioxidant enzymatic activities were recorded in fish fed PBM. Overall, it can be concluded that a total substitution of FM protein by methionine supplemented PBM negatively influenced the growth performance, liver health, histological traits of different organs, immune and antioxidant response, and expression of stress-related genes in juvenile barramundi.
