The review explores new developments and potential future breakthroughs in RAS systems across leading countries. It highlights technical and technological advancement in plant management aimed at improving water quality, production efficiency, and animal welfare. A significant aspect of recent progress is the integration of artificial intelligence (AI), which is being used to optimize system performance, enhance monitoring, and support more precise and predictive management strategies. The review also addresses advancements in pathogen control and the prevention of disease outbreaks. Specific case studies of cutting-edge RAS systems from different parts of the world are discussed. The review also investigates how the improvements in RAS technology can help mitigate environmental impact. Finally, the paper focuses on advancements in the production of six fish species farmed in Europe, namely Atlantic salmon (<i>Salmo salar</i>), European seabass (<i>Dicentrarchus labrax</i>), gilthead seabream (<i>Sparus aurata</i>), yellowtail kingfish (<i>Seriola lalandi</i>), arctic charr (<i>Salvelinus alpinus</i>), and rainbow trout (<i>Oncorhynchus mykiss</i>).

Here, we evaluate the effects of several vegetable diets on the survival and growth of early juveniles of <i>P. lividus</i>. Using an outdoor experimental assay, we fed early juveniles (5–6.5 mm) various diets: fresh algae (<i>Ulva</i> sp.), aquaculture pellets, and vegetables (carrot, spinach, and maize) presented as individual or mixed diets (equal mass proportions). All diets were provided <i>ad libitum</i> in equal mass proportions. After 120 days, the pellet-fed urchins showed good growth but a high mortality rate (&gt;40%).

Therefore, this study used label-free quantification liquid chromatography-mass spectrometry (LFQ—LC-MS/MS) and identified infection-biased expression of the protein in the skin mucus of <i>G. catla</i> after <i>Aeromonas hydrophila</i> infection. In total, 1545 proteins in the skin mucus of nontreated fish and 1400 proteins in the treated fish were identified, of which 1335 proteins overlapped between the two groups, 137 differentially expressed proteins (DEPs) were found, where 71 proteins were downregulated and 66 proteins were upregulated. Functionally, the 137 DEPs were immune-related, bactericidal, and cytoskeleton proteins. The most significant and upregulated protein in the skin mucus of treated fish were ribosomal proteins (40S ribosomal protein S19 (20-fold change (FC)), 60S ribosomal L7a (20-FC), 60S ribosomal L12 isoform X1 (21-FC), and 60S acidic ribosomal P0), beta-actin (24-FC), immunoglobulin mu heavy chain (20-FC), glucose-regulated protein 78 (GRP78; 20-FC), epithelial cell adhesion molecule-like protein (20-FC), putative complement c 3.3 (20-FC), 14 kDa apolipo (19-FC), hemoglobin subunit beta-like protein (19.3-FC), annexin A1-like protein (19-FC), proliferating cell nuclear antigen (18-FC), G-type lysozyme (18-FC), and keratins such as type I cytoskeletal 47 kDa-like isoform X1 (23-FC), and type II cytoskeletal 8 (23-FC).

The coastal region of Bangladesh, prone to frequent natural disasters, necessitates the development of resilient food production systems.

The study design involved three treatment groups from the local communities, namely: local farmers (<i>T</i>1), school teachers (<i>T</i>2), and boat sailors (<i>T</i>3). The aquaponics system was stocked with monosex tilapia (<i>Oreochromis niloticus</i>) fry and various fast-growing vegetable crops. The tilapia fry had an initial mean length of 7.1 ± 0.845 cm and weight of 10.02 ± 0.02 g and were introduced at a stocking density of 95 fry per 0.8 m³ in a 1000-L capacity water tank. Seedlings of tomato, basil, turnip, cauliflower, and eggplant were planted in separate tubs and tank heads within the aquaponic systems. Results indicated that both fish and plant production in the treatment managed by local farmers surpassed that of other community groups. Treatment <i>T</i>₁ demonstrated the highest fish production at 1542.69 ± 1.0 kg/ha/120 days, followed by <i>T</i>₂ (1317.44 ± 0.37 kg/ha/120 days) and <i>T</i>₃ (1278.204 ± 0.37 kg/ha/120 days).

The present study assessed how AO inclusion at different levels in a plant-based shrimp feed could promote growth and fatty acid (FA) deposition in the muscle. Pacific white shrimp, <i>Litopenaeus vannamei</i>, were fed a reference diet with marine animal ingredients (F0) or a marine-free plant-based diet with vegetable oil (VO) alone (P0), or in combination with 1% (P1) or 2% (P2) AO.

The sensory attributes of shrimp fed P1 and P2 were slightly improved relative to P0 while the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content was three to four times higher, thereby increasing the nutritional value of shrimp. Therefore, plant-based feeds can sustain an efficient production of <i>L. vannamei</i> with controlled FA profiles, provided they are supplemented with AO.
