The metabolic itaconate molecule, known for its antioxidant, anti-inflammatory, and immunomodulatory properties, has emerged as a promising candidate. However, limited research exists on the specific effects of 4-octyl itaconate on the growth, immunity, inflammation, and disease resistance of Nile tilapia (<i>Oreochromis niloticus</i>). Thereafter, this experiment assessed the impacts of dietary 4-octyl itaconate (DMIC) supplementation on water quality, growth, blood parameters, and inflammation biomarkers of Nile tilapia (<i>Oreochromis niloticus</i>) and resistance to <i>Aeromonas hydrophila</i> infection. The fish (<i>n</i> = 160) were divided equally into four separate groups (each with four replicates). Over a 56-day period, fish (20.97 ± 0.33g) were fed a basal diet mixed with different levels of DMIC: 0 (DMIC0), 50 (DMIC50), 100 (DMIC100), and 200 (DMIC200) mg/kg of diet. All DMIC groups showed improved growth indices and feed intake compared to the control group (<i>P</i> &lt; 0.05). Feed conversion ratio and water temperatures were not affected (<i>P</i> &gt; 0.05). All DMIC-supplemented groups significantly reduced salinity, pH, dissolved oxygen, ammonia, nitrite, and nitrate (<i>P</i> &lt; 0.001). DMIC significantly improved antioxidant levels (superoxide dismutase, glutathione, and catalase enzymes), immunity markers, and blood hematology (<i>P</i> &lt; 0.001). All DMIC-treated groups displayed greater phagocytic activity, while serum levels of MDA, liver, and kidney functions were significantly decreased (<i>P</i> &lt; 0.01). Fish fed with DMIC exhibited a significant reduction in serum levels of the pro-inflammatory cytokines including tumor necrosis factor-α and interferon-γ and interlukin-4 (<i>P</i> &lt; 0.05) compared to the control fish. Fish infected with <i>A. hydrophila</i> and fed DMIC showed higher survival rates. Incorporating 4-octyl itaconate (100 or 200 mg/kg) into the diet of Nile Tilapia has the potential to improve water quality, enhance blood parameters, boost immune function, increase antioxidant capacity, and struggle resistance to <i>A. hydrophila</i> infection for sustainability the productivity and well-being of cultured Tilapia fish.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a 2 × 2 factorial experimental design, with DPSs consisting of mostly plant or fishmeal proteins extruded at 120 °C (DP1 and DA1 diets) or 140 °C (DP2 and DA2 diets) for grass carp. The growth trial was performed for 9 weeks, and the gut microbiota trial lasted 4 weeks. Compared with the fishmeal-based diets, the plant protein-based diets produced higher expansion ratios (<i>P</i> &lt; 0.001). A high ET also improved the expansion ratio (<i>P</i> &lt; 0.001) and significantly decreased the feed pellet bulk density (<i>P</i> &lt; 0.001). The DP2 diet had the highest hardness and water solubility index and the lowest water absorption index. The DP1 diet exhibited the lowest protein and phosphorus apparent digestibility coefficients (ADCs). The ET significantly affected the ADCs for the plant protein-based diets, but not for the fishmeal-based diets. Grass carp fed the DP1 diet presented the lowest weight gain and specific growth ratio. The interactions between DPS and ET affected the final body weight (<i>P</i> = 0.030), protein efficiency ratio (<i>P</i> = 0.011), and feed efficiency (<i>P</i> = 0.016), and these indices were significantly greater in grass carp fed the DP2 diet than in those fed the DP1 diet. However, DPS and ET did not affect the concentrations of crude protein or amino acids in the dorsal muscle. Compared with grass carp fed plant-based diets, those fed fishmeal-based diets presented greater fat contents in the muscle (<i>P</i> = 0.011) and liver <i>P</i> = 0.037), and a greater hepatosomatic index (<i>P</i> = 0.003). The interaction of DPS and ET influenced the viscerosomatic index (VSI, <i>P</i> = 0.001), with the highest VSI found after feeding the DA2 diet. DPS (<i>P</i> = 0.001) but not ET (<i>P</i> = 0.172) significantly affected the gut microbial communities, although the plant protein-based diets with increased ET resulted in more differential taxa and greater differences in the abundances of the core microbiota in grass carp compared to the fishmeal-based diets. These results indicate that improving the ET of plant protein-based diets can alter the physical qualities of the diets, further affecting the gut microbiota, and enhancing the growth performance of grass carp. These findings reveal that higher ETs are needed for plant protein-based diets than for fishmeal-based diets, which is a valuable guideline for feed production.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10499-024-01768-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142694847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, this study is aimed at investigating the metabolic daily rhythm of hybrid groupers in RAS and its impact on water quality.

Initially, we measured the levels of dissolved oxygen (DO), total ammonia nitrogen (TAN), and nitrite nitrogen (Nitrite-N) in the RAS.

Finally, we conducted a comprehensive analysis of these factors. The results indicated that DO was negatively correlated with OCR, pepsin and lipase activities, and GK gene expression. TAN exhibited a positive correlation with OCR and the expression levels of the target of rapamycin (TOR) gene. Similarly, Nitrite-N showed a positive correlation with OCR and TOR gene expression levels. We also speculated on the internal relationship between fish daily rhythms and water quality parameters, noting a certain degree of synchronicity.

Nine experimental diets containing graded levels of crude lipid (8%, 12%, and 16%) and crude protein (45%, 50%, and 55%) were formulated in a 3 × 3 factorial design. Eight hundred and ten mandarin fish (mean initial body weight, 20.90 ± 0.02 g) were randomly assigned into 27 tanks (1000 L) and triplicate tanks of fish were fed one of the experimental diets twice daily for 56 days. The results showed that a 16% dietary lipid level could significantly increase the survival rate of cultured fish, while a 55% dietary protein level could significantly increase the final body weight and specific growth rate of mandarin fish. Additionally, there was a significant interaction between dietary lipid and protein levels in terms of feed intake and protein digestibility. Further, the whole body and liver lipid content of cultured fish significantly increased with the increase of dietary lipid level, while the provision of dietary protein level significantly decreased the liver crude lipid content, and there was a significant interaction between dietary lipid and protein levels on the moisture, protein, and lipid content of the liver of cultured fish. In terms of hepatic antioxidant capacity, the total anti-oxidative capacity and the activities of catalase and superoxide dismutase decreased significantly with increasing dietary lipid or protein content. As to flesh quality, muscle hardness, chewiness, gumminess, and shear increased significantly with decreasing muscle lipid content, which is significantly influenced by dietary lipid content.
