A 9-month grow-out experiment was conducted from February to November in earthen ponds (529 m² each) with four replicates per treatment, using an initial stocking density of 2.27 ind./m². Significant growth differences were observed during the later grow-out stage, and females in the F25 treatment and males in the F0 treatment had higher average body weight and weight gain rate. During the late grow-out stage, the percentage of males that finished puberty molting was significantly higher in the F75 treatment than in the F25 and F0 treatments on September 30 (<i>P</i> &lt; 0.05), whereas no significant differences were detected among females from different treatments during the July–October. At the end of the grow-out experiment, female survival rates were significantly higher in the F25 treatment than in the other treatments (<i>P</i> &lt; 0.05), while the F50 treatment exhibited the lowest total yield but the highest limb absence rate and feed conversion ratio. Furthermore, although total crab yield was highest in the F0 and F25 treatments, the economic analysis revealed significantly higher net profit and return on investment (ROI) in the F100 and F75 treatments (<i>P</i> &lt; 0.05).

However, existing image-based methods cannot effectively capture temporal changes in feeding behavior, while conventional video-based models often introduce high computational complexity, limiting their practical deployment in real-time automatic feeding systems. Therefore, this study proposed a lightweight video classification model, temporal-spatial-channel-global enhanced TSM (TSCG-TSM), for fish feeding intensity assessment in RAS. The model adopted the Temporal Shift Module to enable 2D CNNs to extract spatiotemporal features through parameter-free temporal information exchange. On this basis, TSCG-TSM implemented three task-specific structural optimizations tailored to the fish feeding intensity assessment. First, the Temporal Attention Module was designed to replace the average consensus, allowing the model to adaptively assign weights to different temporal segments to enhance key-frame modeling. Then, the spatial-channel gated module enhanced feeding-related regions and semantic channels by recalibrating convolutional features across the spatial and channel dimensions. Finally, global response normalization can regulate global channel responses, enhance inter-channel competition, and improve feature diversity. Experimental results demonstrated that TSCG-TSM achieved an accuracy of 86.30% ± 1.94% and F1-score of 86.56% ± 1.98%. These are 4.11% and 4.35% higher than baseline, respectively, while increasing Params and FLOPs by only 0.87 M and 0.85 G. Moreover, TSCG-TSM achieved the best performance compared with 12 representative video-based models (best accuracy = 81.85% ± 2.23%, best F1-score = 82.15% ± 2.23%) These results demonstrate that TSCG-TSM achieves a balance between performance and computational complexity, showing potential for practical automatic feeding applications in RAS.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"34 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190024","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}

However, the tolerance of largemouth bass (<i>Micropterus salmoides</i>) to saline-alkaline exposure during early developmental stages remains unclear. Therefore, this study systematically evaluated the effects of single salinity (S0-S18, ppt), single alkalinity (A0-A40, mmol/L), and their combined exposure on egg hatching rate, larval survival, and early growth and development of largemouth bass. Single stress experiments indicated that the safe thresholds for salinity and alkalinity were 6 ppt and 15 mmol/L, respectively. The 96-h median lethal concentrations (LC₅₀) for larvae were 9.76 ppt and 26.79 mmol/L, respectively. Based on these safety thresholds, combined stress experiments revealed that hatching and larval survival rates in the S6-A15 (6 ppt -15 mmol/L), S6-A20 (6 ppt -20 mmol/L), and S8-A15 (8 ppt -15 mmol/L) groups were not significantly different from the control, while the other salinity-alkalinity combinations exhibited varying degrees of synergistic effects. Furthermore, yolk consumption and conversion rates in the S6-A15 and S6-A20 groups were similar to those of the control. Notably, the total body length of larvae in the S6-A15 group at 20 days post-hatching (22.1 ± 2.33 mm) was significantly (<i>P</i> &lt; 0.05) greater than that in the freshwater group (17.4 ± 0.89 mm), indicating that a suitable saline-alkaline exposure could promote early development in largemouth bass.

The search, conducted on 19 June 2026, identified 834 records; after screening and eligibility assessment, 30 studies were included in the thematic synthesis. In Vietnamese integrated mangrove-shrimp systems, mangrove-to-pond ratios of 42.00–72.50% corresponded to total shrimp yields of 76.62–249.09 kg ha⁻¹ year⁻¹, with black tiger shrimp contributing 37.93–108.64 kg ha⁻¹ year⁻¹. Survival evidence was less standardized: a controlled leaf-litter study reported <i>P. monodon</i> survival of 62 ± 14 to 70 ± 8%, field evidence linked greater mangrove cover with higher shrimp survival, and poor water exchange or high direct litter loading was associated with deterioration in water quality and survival. Comparable milkfish survival data were too sparse for a defensible range, identifying a major evidence gap. Across the evidence base, mangrove integration can support production through natural food-web enhancement, biofiltration, sediment stabilization, and ecological buffering, but these benefits depend on pond design and management. Excessive or poorly managed leaf litter, weak water exchange, acidic or organically enriched sediment, and limited farmer capacity can reduce environmental quality and depress yield. The review concludes that silvofishery should be managed as a site-specific socio-ecological aquaculture system rather than a universal conservation solution.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"34 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189230","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}

Growth performance, feed utilization, water quality, biofloc characteristics, body proximate composition, biochemical profiles, antioxidant capacity, immune responses, and reproductive parameters were assessed in both males and females. Salinity significantly affected most measured variables. Rearing at 18‰ was associated with improved dissolved oxygen levels, higher biofloc protein content, enhanced feed efficiency, stronger antioxidant and immune responses, and higher survival compared with 36‰. Although fish maintained at 36‰ achieved greater final body weight, they exhibited elevated physiological stress indicators, including increased cortisol levels and liver enzyme activities. Increasing stocking density impaired water quality, reduced feed efficiency, and weakened antioxidant and immune defenses. Importantly, juvenile rearing conditions exerted persistent effects on adult reproduction, with fish reared at 18‰ and lower stocking densities during phase I demonstrating superior fecundity, spawning frequency, sperm quality, and reproductive hormone levels. The differences between density treatments were amplified at 36‰, reflecting significant salinity × density interactions.
