A 12-week feeding trial was conducted to evaluate the effects of substituting wheat bran with palm kernel meal (PKM) on the growth performance and intestinal health of grass carp (<em>Ctenopharyngodon idellus</em>). Six isoproteic (crude protein 32 %) and isolipidic (crude lipid 6 %) diets were formulated, incorporating varying levels of PKM replacing wheat bran: 0 % (PKM0), 20 % (PKM20), 40 % (PKM40), 60 % (PKM60), 80 % (PKM80), and 100 % (PKM100). Juvenile grass carp, with an initial body weight of 7.14 ± 0.04 g, were fed twice daily to satiation. The results indicated that PKM could completely replace wheat bran without compromising the growth performance of grass carp, with optimal growth observed at 40 % replacement level. High substitution levels (≥40 %) significantly increased intestinal trypsin and amylase activities, but decreased plasma contents of lipopolysaccharide, D-lactic acid, and endothelin-1. Partial substitution of wheat bran with PKM (20<img>40 %) significantly upregulated the relative expression of <em>zo-1</em> and <em>occludin</em> in midgut, whereas higher replacement levels (40<img>100 %) generally upregulated the relative expression of <em>tgf-1</em> and <em>il-10</em>. Similarly, high replacement levels (≥60 %) generally increased the contents of intestinal mucin 2, complement 4 and immunoglobulin M. In conclusion, the complete substitution of wheat bran with PKM did not adversely affect the growth performance of grass carp, with optimal growth occurring at 40 % replacement level. Additionally, high substitution levels (≥40 %) generally improved intestinal health by enhancing digestive enzyme activity, reducing intestinal mucosal permeability, and mitigating intestinal inflammatory responses.</div></div>","PeriodicalId":8103,"journal":{"name":"Aquaculture Reports","volume":"42 ","pages":"Article 102763"},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683283","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}

In this study, a short-term feeding experiment (35 days) was designed to explore the effects of <em>A. clypearia</em> extract (AE), on growth, intestinal morphology, antioxidant status, immune function and intestinal flora of bullfrog fingerlings. After feeding, bullfrogs were experimentally infected with <em>Elizabethkingia miricola</em> and monitored for an additional 14 days.

Four isonitrogenous (43 %) and isolipid (16 %) diets with 0 mg/kg, 100 mg/kg, 425 mg/kg and 1800 mg/kg RES were formulated respectively, which named R0, R1, R2 and R3, and administered to the grouper for a 42-day period. The results showed that hepatic somatic index (HSI) and whole-body crude lipid were significantly lower in the RES-treated groups, and visceral somatic index (VSI) was significantly lower in the R3 group than those in the control group (<em>P</em> &lt; 0.05). The addition of RES decreased serum levels of total cholesterol (TC) and low-density lipoprotein (LDL), and increased levels of triglyceride (TG) and high-density lipoprotein (HDL). Addition of moderate amounts of RES reduced hepatic TC, TG and very low-density lipoprotein (VLDL) content as well as fatty acid synthase (FAS) and acetyl coenzyme A carboxylase (ACC) activities, and increased lipoprotein lipase (LPL) and hepatic lipase (HL) activities. The number and area of hepatic lipid droplets were found to be significantly reduced in the RES-treated groups in comparison to the control group. RES significantly up-regulated the expression of peroxisome proliferator-activated receptor α (<em>pparα</em>) and lipoprotein lipase (<em>lpl</em>), and down-regulated the expression of peroxisome proliferator-activated receptor γ (<em>pparγ</em>) and fatty acid synthase (<em>fas</em>) (<em>P</em> &lt; 0.05).

The findings revealed that substituting CS with HACS in the feed elevated the final body weight, weight gain rate, and specific growth rate of largemouth bass. Additionally, the dietary replacement of CS with HACS tended to downregulate the hepatic mRNA expression levels of pro-apoptotic regulators (bcl-2 associated x a, apoptosis-related cysteine peptidase 3, and apoptosis-related cysteine peptidase 7) in largemouth bass. Histological examination of the liver indicated that the HACS2.5 group had a more intact and distinct hepatic structure than the HACS0 group. Moreover, dietary substitution of CS with HACS reduced serum triglyceride levels and liver lipid content, and there was a tendency to downregulate the mRNA expression of lipid synthesis metabolism-related genes (acetyl-CoA carboxylase 1, sterol regulatory element binding transcription factor 1, fatty acid synthase) in the liver.

Recirculating aquaculture systems (RAS) and biofloc are the predominant production systems, often featuring alarm notifications. Daily system checks and animal health assessments are common, with records for behaviour and physical health monitoring, regardless of system type. Enrichment strategies, like artificial substrates and feeding trays, are frequently used. Exuviae management is debated and it is removed manually or automatically, although shrimps also consume them.

This study proposes an identification model, DCW-YOLO, based on deep learning-driven object recognition technology. By capturing images of fish in a seabed environment, the model can detect fish showing signs of skin diseases. Currently, there is limited research on automatic fish disease recognition specifically for Miichthys miiuy. To address this gap, we introduce, for the first time, a novel dataset for Miichthys miiuy and train, validate, and test the model on this dataset. DCW-YOLO substitutes the CIoU loss function in YOLOv10 with the NWD loss function, thereby improving the model’s ability to detect densely packed targets. The C2f-D-LKA layer is employed in place of the C2f convolutional layer, improving the model’s capacity to capture irregularly shaped and sized objects while effectively reducing computational overhead and parameter load. Additionally, the DySample upsampling structure, which utilizes point sampling, is introduced to increase image resolution without adding significant computational cost. Underwater experimental results show that the mAP50 and precision of DCW-YOLO reach 96.87 % and 95.46 %, respectively, representing improvements of 4.61 % and 3.24 % over the original YOLOv10 model.
