To gain insights into the prevalence and antimicrobial resistance patterns of major bacterial pathogens affecting largemouth bass (Micropterus salmoides) in Pearl River Delta (PRD) region, Guangdong, China, a study was conducted from August 2021 to July 2022. During this period, bacteria were isolated identified internal organs diseased within PRD region. The 11 antibiotics approved for use aquaculture China analyzed 80 strains Edwardsiella piscicida using microbroth dilution method. results showed that 151 isolates obtained 532 samples, with E. (17.29%, 92/532), Aeromonas veronii (4.70%, 25/532), Nocardia seriolae (2.26%, 12/532) being main pathogens. Notably, accounted highest proportion all bacteria, reaching 60.92% (92/151), mainly occurred November April, accounting 68.48% (63/92) cases. symptoms infected included ascites, enteritis, hemorrhaging tissues organs. drug sensitivity rates ciprofloxacin, sulfonamides, thiamphenicol, florfenicol, enrofloxacin, doxycycline, flumequine, neomycin 96.25%, 60–63%, 56.25%, 43.75%, 40%, 32.5%, 16.25%, 1.25%, respectively. In addition, 76.25% (61/80) these demonstrated more than two types antibiotics. Cluster analysis revealed 23 antibiotic (A–W) among isolates, which clustered groups. Therefore, tailored treatment based on regional is essential effective disease management. findings indicate event an infection bass, neomycin, flumequine are viable options. Alternatively, one may choose drugs as determined by clinical testing.

Microorganisms play a key role in fish spoilage and quality deterioration, making the development of rapid, accurate, efficient technique for detecting surface microbes essential enhancing freshness ensuring safety mandarin consumption. This study focused on total viable count (TVC) Escherichia coli levels dorsal ventral parts fish, we constructed detection model using hyperspectral imaging data fusion. The results showed that comprehensive simplified models were successfully developed quantitative across all wavelengths. performed best at predicting microbial growth side, with RAW-CARS-PLSR proving most effective TVC E. counts region. RAW-PLSR was identified as optimal predictor concentration side. A fusion decision layer Dempster–Shafer theory evidence outperformed relying solely spectral or textural information, it an approach fish. prediction accuracy achieved Rp value 0.9337, whereas reached 0.8443. For concentration, values 0.8180 section 0.8512 separate analysis.
