Summary: The concept of optimizing growth performance and supporting fish health through precise amino acid (AA) nutrition is well-accepted in current Nile tilapia farming. Balanced AAs can contribute to accurately implementing the Precision Nutrition concept and may help assess the economic dimension of the aquaculture system. This review aims to consolidate the relevant published data exploring the amino acid (AA) requirements of Nile tilapia and to reach a new set of recommendations based on those data.

Summary: This study evaluated the effects of dietary supplementation with L-carnitine on growth performance, gut and muscle histological parameters, blood hematology, plasma biochemical parameters, and antioxidant enzymes in Nile tilapia juveniles. Results showed that supplementation with L-carnitine improved growth performance and reduced lipid content in the filet, while also increasing the activity of the enzyme catalase in the liver. Different inclusion levels of L-carnitine had varying effects on weight gain, fat deposition, and triacylglycerol in the fish.

Summary: The aim of this study was to extract and characterize hyaluronic acid (HA) from the eyeball of Nile tilapia, which is a valuable resource in fish industry residue. Characterization through FTIR, 13C NMR, and HPLC confirmed the presence of HA. GPC analysis revealed a low molecular mass of the extracted material. Thermal analysis and XRD showed that the extracted HA had superior thermal stability and partially crystalline characteristics compared to commercial HA. Cytotoxicity assay demonstrated that the extracted HA was not cytotoxic and could stimulate cell proliferation, indicating its potential for biomedical applications.

Summary: In this study on the 16th generation of Genetically Improved Farmed Tilapia, clear genotype-growth associations were found in both normoxic and hypoxic environments. MAPK and VEGF signaling pathways were identified as important components in hypoxic environment, especially during the later growth stage. A meta-analysis showed shared effects across both environments, with functional pathways playing different roles in nervous system development, organ growth, and oocyte maturation at different growth stages.

Summary: The indoor feeding trial aimed to optimize the amino acid profile of GIFT diet by utilizing the AA deletion method. Different diets were formulated, and supplementation of crystalline AAs showed effects on growth performance and feed utilization of juvenile GIFT tilapia. The EAA pattern associated with -Trp diet was considered optimal for maximum growth and feed efficiency.

Summary: The study evaluated the effects of a probiotic additive on tilapia growth by observing growth curves, muscle and adipose tissue morphology, carcass characteristics, and gene expression related to growth. The probiotic mixture significantly improved growth rates, feed conversion rate, and final weight of the tilapia. The additive promoted white muscle fiber hypertrophy, inhibited specific gene expressions, and increased intestinal villi, enhancing nutrient absorption and utilization.

Summary: This study used an integrative omics approach to identify myogenic circular RNAs (circRNAs) in Nile tilapia, and found 1947 mRNAs, 9 miRNAs, and 4 circRNAs that were differentially expressed between fast- and slow-growing individuals. These miRNAs can regulate myogenic genes and have binding sites for the novel circRNA circMef2c. The study suggests that circ-Mef2c may interact with three miRNAs and 65 differentially expressed mRNAs to form multiple competing endogenous RNA networks that regulate growth, providing new insights into the role of circRNAs in muscle growth regulation in teleosts.

Summary: Cannabidiol (CBD), derived from Cannabis sativa, has been widely studied for its neuroprotective effects in humans. This study investigated the effects of different CBD doses on the aggressiveness, stress, and reproductive development of Nile tilapia fish. The results showed that CBD supplementation reduced aggressiveness and non-social stress in a dose-dependent manner, while also increasing the gonadosomatic index. However, lower doses of CBD decreased the number of spermatozoa. Despite this effect, CBD supplementation has the potential to improve the welfare of animals in artificial environments.

Summary: The marine microalga Nannochloropsis oculata has great potential for nutraceutical and functional food industry applications due to its bioactive compounds and high omega-3 polyunsaturated fatty acid content. In this study, Nile tilapia fed diets supplemented with N. oculata showed improved growth performance, proximate composition, lipid profile, and gene expression pattern related to lipid metabolism and immune response. Histopathological examination confirmed the benefits and safety of N. oculata dietary inclusion. Overall, N. oculata is a promising nutraceutical for enhancing fish health and sustainability in aquaculture production.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
