Therefore, we have designed a feeding trial to assess the impacts of dietary incorporation of <i>Perovskia abrotanoides</i> extract (PAE) on common carp (<i>Cyprinus carpio</i>). For this purpose, five isonitrogenous (35% protein) and isocaloric (~4,000 kcal/kg) diets have been supplied by supplementing PAE at the varying inclusion levels as 0.0%, 0.25%, 0.5%, 1.0%, and 2.0% diets, and growth performance and feed utilization, digestive enzyme activities, serum biochemical variables, antioxidant responses, and immunological factors were studied. The experiment continued for 60 days. At the termination of the experiment, the mean final weight, weight gain percentage (WG%), feed conversion rate (FCR), and specific growth rate (SGR) have been improved significantly in all fish groups fed PAE-based diets with regard to those fed the reference diets. A second-order polynomial regression equations indicate that the optimum dietary supplementation level of PAE in fish diets was ~1%. Serum cortisol, glucose, triglyceride, cholesterol, and malondialdehyde levels as well as catalase, alanine aminotransferase, and aspartate aminotransferase activities were significantly decreased generally in all PAE-supplemented groups compared to the control groups before and/or after high-temperature stress (32°C). Moreover, serum total protein, albumin, and total immunoglobulin levels as well as ACH50, lysozyme, superoxide dismutase, and glutathione peroxidase activities were increased before and/or after high-temperature stress (32°C). In conclusion, the results showed, for the first time, that dietary supplementation with ~1% PAE can improve growth performance, stimulated the digestive enzymes, and enchanced antioxidant status as well as immune parameters and prevented high-temperature stress of common carp.</p>\u0000 </div>","PeriodicalId":8225,"journal":{"name":"Aquaculture Nutrition","volume":"2024 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5526562","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141488694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven isonitrogenous and isolipidic experimental diets were formulated by replacing 0%, 20%, 40%, 60%, 80%, and 100% of dietary SBM with SM or FSM. The results showed that the replacement of more than 40% of SBM with SM decreased the weight gain and special growth rate of tilapia, while the complete replacement of SBM with FSM did not affect the growth performance of tilapia. From transmission electron microscopy analyses, it was shown that high levels of both SM and FSM substitution resulted in damage to the intestinal epithelium of tilapia. Replaced of 20% SBM with SM upregulated intestinal tight junction (<i>zo-1</i>, <i>claudin</i>, <i>occludin</i>) and anti-inflammatory (<i>tgf-β1</i>, <i>tgf-β2</i>) gene expression and downregulated pro-inflammatory gene expression (<i>tnf-α</i>, <i>il-1β</i>, <i>il-6</i>, <i>il-8</i>). However, the expression of tight junction, anti-inflammatory, and pro-inflammatory genes showed opposite trends when SBM was substituted by SM at high levels. FSM completely replaces SBM and downregulates the expression of tight junction genes (<i>claudin</i>, <i>occludin</i>), replacement of more than 20% of SBM with FSM downregulated pro-inflammatory (<i>tnf-α</i>, <i>il-1β</i>, <i>il-8</i>) gene expression, whereas substitution of less than 80% increased the expression of anti-inflammatory genes (<i>tgf-β1</i>). The 100% FSM group exhibited a decreased abundance of Fusobacteriota and an increased abundance of Actinobacteriota compared to the control and 100% SM groups. In summary, our data confirm that replacing more than 40% of SBM with SM induces gut inflammation, damages gut health, and decreases growth performance, whereas FSM replacement of SBM did not negatively affect tilapia growth and health, it also did not have a significant ameliorative effect, with some parameters negatively affected at high replacement levels. Therefore, FSM replacement of SBM levels above 80% is not recommended.</p>\u0000 </div>","PeriodicalId":8225,"journal":{"name":"Aquaculture Nutrition","volume":"2024 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/9366952","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six diets containing different amounts of EA (0, 3, 6, 12, 20, and 27 g/kg diet) were fed to tilapia (initial weight: 3.01 ± 0.01 g) for 8 weeks. The results exhibited that dietary EA did not affect growth performance but remarkedly increased the crude lipid contents (in the whole body, liver, and muscle). It also markedly increased the levels of low-density lipoprotein cholesterol, total cholesterol, nonesterified fatty acids, and triglyceride in the liver and serum in a dose-dependent manner. The EA groups had lower values of total superoxide dismutase, total antioxidant capacity, catalase, and higher activities of aspartate aminotransferase and alanine aminotransferase, as dietary EA levels increased. Feeding fish with diets containing EA (20 and 27 g/kg diet) significantly increased the malondialdehyde content. Moreover, dietary EA greatly altered the fatty acid profile in the liver and muscle.

Over a 60-day period, 180 common carp fingerlings (11.73 ± 0.52 g) were subjected to diets supplemented with increasing WSRP levels (0 (control), 1% (WSRP1), 2.5% (WSRP2.5), and 4% (WSRP4)). Nonspecific immune parameters were evaluated using serum samples collected at intervals of 0, 20, 40, and 60 days. After the feeding trial, the fish underwent experimental challenge with <i>Aeromonas hydrophila</i>, and relative percentage survival (RPS) was monitored for 14 days. The findings revealed a considerable (<i>p</i>  &lt; 0.05) enhancement in growth performance and a decreased feed conversion ratio (FCR) with increasing WSRP supplementation. Additionally, hematological and biochemical profiles exhibited improvements in groups receiving WSRP-enriched diets. Fish serum antioxidant status showed a significant (<i>p</i>  &lt; 0.05) increase, as indicated by increased activities of total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) in WSRP4. WSRP-supplemented diets led to remarkable enhancements in lysozyme activity (<i>p</i> = 0.001), phagocytic activity (<i>p</i> = 0.002), and RPS (<i>p</i> = 0.003), peaking in WSRP4 at day 60. Furthermore, WSRP2.5 and WSRP4 demonstrated a substantial decrease (<i>p</i>  &gt; 0.05) in serum glucose and cortisol levels compared to other groups. In conclusion, WSRP proves valuable for enhancing growth, blood parameters, antioxidant balance, immune response, and infection resistance in common carp, especially at 2.5%–4% dietary supplementation levels. In the future, it will be crucial to study the long-term effects of WSRP supplementation on fish health, as well as its potential for large-scale aquaculture and economic viability in the aquafeed industry.</p>\u0000 </div>","PeriodicalId":8225,"journal":{"name":"Aquaculture Nutrition","volume":"2024 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/7321287","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141315509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 540 juveniles (36.06 ± 0.05 g) were stocked into eighteen 200 L tanks and divided into six experimental treatments, each in triplicate. Fish were fed diets containing 0 (control), 3% (SW3), 6% (SW6), 9% (SW9), 12% (SW12), and 15% (SW15) mixtures of both seaweeds powder in equal proportions (1 : 1) for 56 days. There was no improvement in weight gain parameters. Serum lysozyme and peroxidase activities in SW9 and SW12 treatments were significantly higher in compare to other treatments. The highest activities of skin mucus lysozyme, alkaline phosphatase, and total protease were observed in the SW12. Liver <i>igf-1</i>, <i>il-1β</i>, <i>il-8</i>, and <i>lysozyme</i> expression showed a rising trend up to SW9 and then decreased. Liver antioxidant enzymes activity and glutathione content showed a similar pattern of changes. Liver total antioxidant capacity was highest in the SW9 treatment, while the lowest value of liver malondialdehyde was observed in the 12% seaweed treatment. The amount of total n-3 polyunsaturated fatty acids, especially docosahexaenoic acid, was higher in the SW12 and SW15 treatments in compare to others. Our findings suggest that adding 9%–12% of Gracilaria and Sargassum seaweed powder to the diet improves serum and mucosal immunity, antioxidant status, and fatty acid profile in <i>L. calcarifer</i> juveniles.</p>\u0000 </div>","PeriodicalId":8225,"journal":{"name":"Aquaculture Nutrition","volume":"2024 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/3683163","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141264655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
