To address this issue, 135 S. maximus (mean dry weight 6 ± 0.05 g) were subjected to a 42-day experiment in three RAS setups with different DO levels: hypoxia (LF, 4.0 ± 0.5 mg/L), normoxia (NF, 8.0 ± 0.5 mg/L), and hyperoxia (HF, 24.0 ± 0.5 mg/L). DO was regulated using nitrogen–oxygen (N2-O2), air aeration (Air-O2), and oxygen nanobubbles (NB-O2). This study evaluated organ morphology, including the skin, skeleton, gills, and intestine, alongside assessments of organ function such as intestinal digestive enzyme activity, liver antioxidant capacity, and muscle metabolism. The results showed that the LF group had the worst growth performance and the HF group had the best growth performance. The HF group showed swelling in the gill lamellae, suggesting respiratory organ abnormalities. Digestive enzyme activity was lowest in the LF group; in contrast, the HF group showed the highest activity. Both LF and HF groups experienced oxidative stress, as indicated by increased antioxidant enzyme activity, including peroxidase (POD), total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD), and catalase (CAT). Muscle metabolism differed: the HF group had higher glycogen (Gn) and total free amino acids (T-AA) but lower adenosine triphosphate enzyme (ATP) activity, while the LF group had increased ATP activity and reduced crude protein and fat. These results indicate that S. maximus can adapt to mild hypoxia and hyperoxia. However, this comes at the cost of altering organ morphology and function.<h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900660","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}

Meteorological factors like temperature, air pressure, and rainfall typically cause significant lag effects on water quality changes. Existing models often rely solely on historical water quality data for predictions, overlooking the influence of meteorological factors. This paper proposes an enhanced deep learning model, the dual encoder cross-source feedback network (DECSF-Net), incorporating a modified dual encoder structure to encode water quality and meteorological data separately. This design accurately captures the complex impact of future meteorological data on water quality time series. The cross-source feedback fusion (CSFF) module enhances mutual attention between water quality and meteorological data through a bidirectional feedback mechanism, improving the model’s ability to jointly represent cross-source data. Experimental results demonstrate that DECSF-Net outperforms existing mainstream methods in predicting water quality for the next 8 h, with a mean squared error (MSE) of 0.0959, mean absolute error (MAE) of 0.2037, root mean squared error (RMSE) of 0.3084, and mean absolute percentage error (MAPE) of 1.5159, showcasing its superior prediction accuracy.

Solid-state fermentation is a promising biotechnological approach to enhance the nutritional profile of plant-based feed ingredients. In this study, Eichhornia crassipes leaf meal was fermented using Aspergillus niger MTCC 281, Bacillus subtilis MTCC 2960, and Chaetomium globosum MTCC 4179, both individually and in combination, to assess their effects on nutrient composition and anti-nutritional factors. Fermentation significantly (p<0.05) improved the nutritional quality of E. crassipes leaf meal, with the highest increase in crude protein (11.93%) observed in B. subtilis-fermented samples and the greatest reduction in crude fibre (15.06%) achieved with C. globosum fermentation. Additionally, fermentation resulted in a statistically significant reduction (p<0.05) of key anti-nutritional factors across all microbial treatments, including tannins (52.36%), phytates (45.60%), saponins (60.83%), and oxalates (72.63%). A quantitative scoring method based on Min-Max normalization identified co-fermentation with A. niger and B. subtilis as the most effective in enhancing the nutritional profile of E. crassipes leaf meal. These findings suggest that solid-state fermentation can transform E. crassipes, an invasive aquatic weed, into a sustainable alternative feed ingredient for aquaculture.
