This study investigated the acute toxicity of Cd on Songpu mirror carp (<em>Cyprinus carpio</em> Songpu) with an average body mass of (35.4 ± 0.4) g. The 96-h median lethal concentration (LC50) of Cd was determined, and the safe concentration (SC) for Cd exposure was determined to be one-tenth of the LC50.Based on these, two exposure levels were set, with three replicates for each treatment. Serum biochemical parameters, liver antioxidant enzyme activities, related gene expression, liver transcript levels, and histological changes were examined at 0, 6, 12, 24, 48, 72, and 96 h after exposure to the safety concentration of Cd. Results showed that the 96-h SC of Cd for juvenile Songpu mirror carp was 1.25 mg/L. Cd exposure decreased the contents of total protein and total cholesterol and increased the contents of glucose and triglycerides in the serum. Cd caused hepatocyte swelling with cytoplasmic cloudiness and granulation. Cd significantly decreased liver antioxidant enzyme activities, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX), and significantly increased malondialdehyde contents. Chronic exposure to Cd significantly up-regulated the gene expression of Keap1 and down-regulated the gene expression of SOD and GPX. KEGG pathway analysis showed that Cd exposure affects lipid and atherosclerosis and steroid biosynthesis in the liver, and regulates immune-metabolism-related TNF signaling pathway, Toll-like receptor signaling pathway, and IL-17 signaling pathway. Overall, chronic exposure to Cd negatively affects serum parameters, reduces hepatic antioxidant capacity, and leads to lipid metabolism disorders and oxidative stress, resulting in immune dysfunction. The present study effectively broadens our understanding of the mechanisms by which Cd exposure damages fish health and provides a theoretical basis for fish liver immune regulation and aquaculture techniques.</div></div>","PeriodicalId":8103,"journal":{"name":"Aquaculture Reports","volume":"42 ","pages":"Article 102757"},"PeriodicalIF":3.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706056","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}

Selective breeding programs have been implemented to ensure the production of high-quality abalone, resulting in genetic improvement within domestic populations. With recent advances in statistical and scientific methodologies, there has been a shift toward genome-based selective breeding methods and away from traditional phenotype- or pedigree-based approaches. To improve the accuracy of genome-based selection, it is necessary to obtain genomic data from as many individuals as possible. Single nucleotide polymorphism (SNP) markers are commonly used genetic markers, which can be analyzed using SNP arrays. Genetic variation can be detected efficiently using SNP arrays, which are semiconductor chips carrying information on tens of thousands of genetic variants. We have developed and validated an abalone SNP array carrying 65,740 variants (60 K abalone SNP array). Utilizing whole-genome sequence data from 29 abalones, the SNP array was designed by extracting and filtering variants based on a number of criteria, including minor allele frequency &gt; 0.2, genotype missing ratio &gt; 0.9, Hardy-Weinberg Equilibrium <em>P</em> &lt; 0.0001, SNP even spacing, and final score &gt; 0.9. Validation experiments demonstrated good performance of the designed SNP array with a call rate of 90.47 %, polymorphic SNPs of 76.03 %, and linkage disequilibrium correlation with whole-genome sequence data of 0.991. This 60 K SNP array is suitable for use in constructing genomic databases and will be beneficial for genome-based selective abalone breeding programs.</div></div>","PeriodicalId":8103,"journal":{"name":"Aquaculture Reports","volume":"42 ","pages":"Article 102770"},"PeriodicalIF":3.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706059","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}

The results indicate that the highest removal efficiencies were achieved at a pH level of 6.5, with a contact time of 67 minutes, a temperature of 30 ^○C, and an adsorbent dosage of 400 mg. Specifically, the removal rates were found to be 93 % for nitrate, 95 % for nitrite, and 96 % for phosphate. These findings demonstrate that LNCFs are not only effective in reducing these pollutants but also possess significant potential as a sustainable solution for wastewater treatment in aquaculture systems. The study emphasizes the critical role of optimizing operational parameters to maximize pollutant adsorption. Furthermore, the successful application of LNCFs in aquaculture practices could enhance environmental sustainability by promoting healthier aquatic ecosystems and effectively addressing the challenges posed by nutrient loading in water bodies.

This is due to concerns over residue accumulation, environmental impact, and growing demand for sustainable practices. Within this context, the present study focused on the anesthetic effects of nutmeg essential oil at three different concentrations in rainbow trout (<em>Oncorhynchus mykiss</em>, 94.42 ± 23.9 g): low (400 µL/L), medium (600 µL/L), and high (800 µL/L). Induction and recovery times were recorded, and samples were collected at 0, 2, 4, and 8 hours post-anesthesia for antioxidant, cortisol, and hematological analyses. Additionally, gill tissues were sampled immediately after anesthesia for histological examination. While the induction time for the low concentration exceeded 3 minutes, the induction and recovery times for the other concentrations ranged within acceptable limits (3 min for induction and 5 min for recovery). Blood parameters exhibited an increasing trend until the 4th hour post-anesthesia, peaking at the 2nd hour, before returning to control levels by the 4th hour. Histological evaluation revealed healthy gill tissues in the control and low-concentration group (400 µL/L), whereas hyperplasia was observed in the medium (600 µL/L) and high-concentration (800 µL/L) groups. Antioxidant enzyme activity (superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px)) indicated potential oxidative stress at the high anesthetic concentration. Similarly, cortisol levels were higher at the high concentration, with plasma cortisol showing a slight initial increase followed by a return to normal levels over time. In conclusion, this study highlights that nutmeg oil at a concentration of 600 µL/L may serve as a promising natural alternative to synthetic anesthetics in aquaculture. However, future studies should include a synthetic anesthetic as a control to allow for direct comparisons and a more comprehensive evaluation of its efficacy and physiological effects.</div></div>","PeriodicalId":8103,"journal":{"name":"Aquaculture Reports","volume":"42 ","pages":"Article 102773"},"PeriodicalIF":3.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703911","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}
