“…Consumption of a diet enriched with omega-3 ( n − 3) PUFAs, especially EPA and DHA, can promote an anti-inflammatory environment within the fish body and thereby strengthening its resistance to infectious diseases and targeting maximum production [ 41 ]. Additionally, the health importance of n − 3 fatty acids to humans is the anticipation of cardiovascular diseases, enhancement of visual insight, and strengthening of mental wellbeing [ 42 ].…”

In modern aquaculture, enriching Nile tilapia’s diet with omega-3 poly-unsaturated fatty acids (PUFAs) not only plays an important role in its general health but also fortifies its fillet with omega-3-PUFAs. However, the major challenge affecting their delivery is their high instability due to oxidative deterioration. Thus, the prospective incorporation of omega-3-PUFAs into nanocarriers can enhance their stability and bioactivity. In this regard, the effect of reformulated omega-3-NPs was investigated on Nile tilapia’s performance, flesh antioxidant stability, immunity, and disease resistance. Four fish groups supplemented with omega-3-PUFAs-loaded nanoparticles (omega-3 NPs) at levels of 0, 1, 2, and 3 g/kg diet and at the end of feeding trial fish challenged with Aeromonas hydrophila. Fish performance (weight gain and feed conversion) was improved in groups supplemented with omega-3-NPs (2 and 3 g/kg diet). The deposition of omega-3-PUFAs in fish flesh elevated with increasing dietary omega-3-NPs. Simultaneously the oxidative markers (H2O2, MDA, and reactive oxygen species) in fish flesh were reduced, especially with higher omega-3-NPs. Post-challenge, downregulation of IL-1β, IL-6, IL-8, TNF-α, and caspase-1 were noticed after dietary supplementation of omega-3-NPs. Moreover, mRNA expression of autophagy-related genes was upregulated while the mTOR gene was downregulated with higher omega-3 NPs levels. Lower expression of A. hydrophila ahyI and ahyR genes were detected with omega-3 NPs supplementation. In conclusion, omega-3-NPs application can fortify tilapia flesh with omega-3-PUFAs and augment its performance, immunity, and disease resistance against Aeromonas hydrophila.

“…Ongoing rapid development of aquaculture has been accompanied by more stressful conditions, which have impaired immune response and augmented disease outbreaks among farmed fish [ 56 ]. Concerning these issues that threaten aquaculture industry, the application of natural functional nutrients enriched with omega-3 (n-3) fatty acids not only has significant regulatory effects on inflammatory response in fish [ 57 ], but also offers healthy food choice for consumers with numerous health outcomes [ 58 ]. It has been shown that many microalgae species have a number of health-promoting impacts, particularly in the prevention and treatment of several diseases owing to their composition from natural antioxidant compounds or production of long-chain PUFAs [ 59 , 60 , 61 ].…”

The oxidative stress facing fish during intensive production brings about diseases and mortalities that negatively influence their performance. Along with that, the increased awareness of omega-3 polyunsaturated fatty acids (omega-3-PUFAs) health benefits has been triggered the introduction of alternative additives in aqua feed that cause not only modulation in fish immune response but also fortification of their fillet. In this context, the role of microalgae mix (NSS) containing Nannochloropsis oculate and Schizochytrium and Spirulina species, which were enriched with bioactive molecules, especially EPA and DHA, was assessed on Nile tilapia’s performance, fillet antioxidant stability, immune response, and disease resistance. Varying levels of NSS (0.75, 1.5, and 3%) were added to Nile tilapia’s diet for 12 weeks and then a challenge of fish with virulent Aeromonas hydrophila (A. hydrophila) was carried out. Results showed that groups fed NSS, especially at higher levels, showed an improved WG and FCR, which corresponded with enhanced digestive enzymes’ activities. Higher T-AOC was detected in muscle tissues of NSS3.0% fed fish with remarkable reduction in ROS, H2O2, and MDA contents, which came in parallel with upregulation of GSH-Px, CAT, and SOD genes. Notably, the contents of EPA and DHA in fillet were significantly increased with increasing the NSS levels. The mean log10 counts of pathogenic Vibrio and Staphylococcus species were reduced, and conversely, the populations of beneficial Lactobacillus and Bacillus species were increased more eminent after supplementation of NSS3.0% and NSS1.5%. Moreover, regulation of the immune response (lysozyme, IgM, ACH50, NO, and MPO), upregulation of IL-10, TGF-β, and IgM, and downregulation of IL-1β, TNF-α, HSP70, and COX-2 were observed following dietary higher NSS levels. After challenge, reduction in A. hydrophila counts was more prominent, especially in NSS3.0% supplemented group. Taken together, the current study encourages the incorporation of such microalgae mix in Nile tilapia’s diet for targeting maximum performance, superior fillet quality, and protection against A. hydrophila.

Background: Jackfruit seeds have been studied in the pharmaceutical industry, one way of exploiting the potential of this ingredient could be as a protein source in the elaboration of fish food. Jackfruit seeds were subjected to different processes to obtain meals to be added to the diet of Nile tilapia (Oreochromis niloticus). The effects of this addition on growth, elimination of antinutritional factors, and repercussion on the health of tilapia was evaluated. Method: For the bioassay of the productive yield, three experimental diets were prepared, consisting of a control diet of fishmeal and four treatments: raw jackfruit seeds (RJS), hulled jackfruit seeds (HJS), extruded jackfruit seeds (EJS) and hulled and extruded jackfruit seeds (HEJS). For the growth study, 1600-L experimental units were used. Three replicates per treatment were used, initial weight of tilapias was of 1.8±0.2 g. At the end of the feeding study, a blood sample was taken from the caudal vein, using a hypodermic syringe and EDTA as anticoagulant for the hematology (hemoglobin/hematocrit). Results: Significant differences among treatments using jackfruit seeds, subjected to hulling and extrusion (CEJS) processes, were observed in weight gain (24.3±1.1 g), whereas blood parameters, the red blood cells (RBC) count and the hematocrit (Hct) were significantly higher in the jackfruit seeds subjected to only one treatment (39.8±6.49) respect to the control diet (27.4±3.18). Regarding the MCH and MCHC variables, lower values were observed with the diets using EDJS, showing a significant diminution in the RBC concentration (13.2±2.5) compared to the control diet (19.3±4.65). The processes used for the jackfruit seeds allowed formulating diets with a higher protein quality, which resulted in an increment in weight gain, without observing any effect on the health indicators and nutritional status of fish.
