Summary: The experiment showed that woody forages (such as Moringa oleifera Lam, Folium mori, and Broussonetia papyrifera) can have a positive impact on the growth and feed utilization of Nile tilapia, without negative effects on intestinal health. Adding 30% Moringa oleifera Lam to the diet could lead to improved growth, feed utilization, and microbiota composition, while adding 30% Neolamarckia cadamba had a negative impact.

Summary: Photosynthesis and respiration have opposite effects on dissolved gases in earthen ponds. Daily variations in dissolved O2 and CO2 strongly affect the appetite and feed utilization in Nile tilapia. Hypoxia and hypercapnia individually and combined amplify the effects on appetite, growth rate, and feed conversion, while digestion is improved in groups exposed to fluctuations in dissolved oxygen and carbon dioxide.

Summary: The optimal enzymolysis conditions for feather meal were found to be 60 min enzymolysis time, 60°C temperature, 1000 g/kg moisture inclusion, and 10 g/kg protease inclusion. Furthermore, enzymatic feather meal was demonstrated to be a suitable substitute for fish meal in tilapia diets, with no negative effects on growth, nutrient retention, and digestibility.

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: This study investigated the effects of different levels of acetylferulic paeonol ester (APE) on the growth performance, body composition, serum biochemical indicators, and lipid and glucose metabolism of Nile tilapia. The results showed that APE supplementation improved weight gain and decreased liver lipid content. It also affected serum biochemical parameters related to lipid and glucose metabolism. Transcriptome analysis revealed changes in gene expression related to fatty acid oxidation and degradation. APE influenced the hepatic glucose and lipid metabolism of tilapia at both enzymatic and mRNA levels.

Summary: This research explores the influence of myo-inositol on the hypertonic stress adaptation of Nile tilapia by increasing lipid utilization and improving osmotic regulation ability. It was found that myo-inositol supplementation improved growth performance, promoted protein deposition, reduced fat accumulation, and alleviated liver lipid accumulation. Additionally, it reduced serum lipids and upregulated the expression of ion transporter-related genes. The findings suggest that dietary supplementation with myo-inositol can regulate lipid metabolism and improve the physiological response of Nile tilapia to hypertonic stress.

Summary: The study showed that dietary lipid levels have a significant impact on the growth performance and lipid metabolism of large-sized common carp. Moderate increase in lipid levels can promote growth and lipid deposition, while excessive intake may inhibit growth and exacerbate lipid decomposition in the hepatopancreas. Optimal dietary lipid levels for growth performance and feed utilization of large-sized common carp were found to be 59.5 and 70.4 g/kg based on weight gain rate and feed conversion rate.

Summary: The study found that dietary NE supplementation positively affected the growth, feed utilization, immune response, and lipid metabolism of juvenile Nile tilapia. NE supplementation improved the final weight, weight gain, feed conversion ratio, and reduced cholesterol levels in the fish. Additionally, dietary NE supplementation was shown to increase antioxidant enzyme activity and reduce oxidative stress.

Summary: A 10-week feeding trial was conducted to determine the optimal dietary methionine requirement of sub-adult turbot. The results showed that fish growth significantly increased with increasing dietary methionine levels up to 1.82% and then plateaued. Adequate dietary methionine improved protein and lipid levels in the whole body and liver. It also increased the content of methionine and other amino acids in the hepatic free amino acid pool and affected the expression of genes involved in lipid metabolism.

Summary: This study evaluated the effects of VILIGEN(TM) supplementation on growth, gut morphology, immune responses, and resistance of Nile tilapia. The results showed that the optimal inclusion level of VILIGEN(TM) promoted higher weight gain and improved gut morphology, but did not clearly affect the response to bacterial challenge.

Summary: This study found that adding Spirulina meal to the diet of European seabass can improve their growth and immunity. After 30 days, respiratory burst activity and lysozyme activity increased significantly, and myeloperoxidase activity increased significantly on the 60th day. IL-1 beta, IL-10, IL-6, and IL-8 gene expressions also increased significantly. Furthermore, fish fed with Spirulina meal showed a higher resistance against Vibrio anguillarum.

Summary: Adding 2 g kg(-1) of surface-modified clinoptilolite to the feed can enhance the growth parameters of fingerling gilthead sea bream in a recirculating aquaculture system. It also improves weight gain, specific growth rate, and feed conversion ratio. However, there were no significant differences in body indices, blood parameters, or whole-body protein and fat levels among the different dietary levels of zeolite supplementation.

Summary: The present study evaluated the health status of rainbow trout acclimated to high-saline water and found that gradual acclimation did not have adverse effects on fish health. Hematology markers showed a time-dependent increase after seawater transfer, but the health status improved over the long-term. Therefore, trout farms can potentially be expanded to higher saline environments without detrimental impacts on fish health.
