The experiment was conducted over six weeks using 12 pilot-scale RAS units, each stocked with juvenile rainbow trout (<em>Oncorhynchus mykiss</em>) in freshwater. Four treatment configurations in triplicate systems were evaluated: drum filter only, a swirl separator combined with a drum filter (Swirl + Drum), a drum filter combined with a foam fractionator (Drum + FF), and a swirl separator combined with a foam fractionator (Swirl + FF). The results showed that the combination of a swirl separators and a drum filter achieved the highest removal of organic matter per day. Despite the high organic matter removal in the Swirl + Drum treatment, it did not translate to the best water quality outcomes, highlighting the importance of addressing dissolved organic matter and fine particulates. Pilot RAS with foam fractionation showed the most significant improvements in water quality parameters, particularly in reducing total BOD, COD, and microbial activity. The Swirl + FF treatment exhibited a large decrease in total BOD (40 % reduction) and total COD (27 %), with microbial activity reduced by over 55 % compared to the RAS with drum filters only. The study also identified that Swirl + FF, led to more total phosphorus and orthophosphate , suggesting that particles smaller than the swirl separator's threshold but too large for foam fractionation contributed to increased phosphorus levels. This study underscores the effectiveness of combining swirl separators and drum filters for particulate removal and highlights the crucial role of foam fractionation in managing dissolved organic matter and enhancing overall water quality in RAS. These findings provide new knowledge of solids removal and water quality and may have important implications for the design and optimization of RAS systems.</div></div>","PeriodicalId":8120,"journal":{"name":"Aquacultural Engineering","volume":"111 ","pages":"Article 102593"},"PeriodicalIF":3.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144549783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results showed that following aquaculture activity, the abundances of fosmidomycin- (an antibiotic targeting the MEP pathway), MLS (Macrolides, lincosamides, streptogramines), phenicol-, and triclosan-related ARGs decreased, while diaminopyrimidine- (interfere with the folic acid metabolism of bacteria), rifamycin-, aminoglycoside- (prevent bacterial protein synthesis), multidrug-, and mupirocin-related ARGs increased, thereby increasing the likelihood of microorganisms acquiring resistance.

This information can guide us in targeting specific types of microorganisms for controlling particular ARGs. Certain ARGs were predominantly located on plasmids, indicating enhanced mobility and an increased risk of horizontal gene transfer.

Underfeeding impedes fish growth, while overfeeding leads to feed waste, increased costs, and water pollution, ultimately compromising fish health. Precise feeding strategies are thus critical for sustainable aquaculture. Existing feeding technologies are primarily limited to indoor environments and specific fish species. Our study aims to extend the research scope to outdoor natural environments, applicable across diverse fish species. We start from the basic biological characteristics of fish, that is, fish will feed when they are hungry, to evaluate fish feeding behavior. We use object detection and counting technology to measure fish appetite by dynamic changes in feeding fish populations. The feeding strategy proposed is more refined and can continuously reflect the changes in the feeding intensity of the fish school. Considering the real-time needs of the application scenario, we select the YOLOv8 object detection algorithm as the basic algorithm. In view of the complexity of natural scenes—where targets are often small and feature-poor—we enhance the YOLOv8 algorithm with a Star operation, CAA module, and DyHead mechanism.

This includes a three-step methodology: (1) Computational fluid dynamics-derived drag coefficients: 2D OpenFOAM simulations determine normal and tangential drag coefficients for mussel droppers; (2) Hydro-elastic finite-element modeling: a time-domain finite-element model driven by Airy-wave kinematics and Morison loads to predict mooring, mainline, strap, and dropper responses under 10-, 25-, and 50-year return-period wave and current scenarios; and (3) Statistical risk assessment: simulation outputs are interpolated to create a continuous response field across the full range of wave heights and current speeds, which is then integrated with a joint probability density function of significant wave height and current speed – alongside component ultimate and residual strength at three growth phases – to estimate failure probabilities over specified design lives and recommend optimized safety factors. Results indicate that combining accurate drag coefficients with a continuous response surface and joint-PDF risk analysis enables systematic estimation of component failure probabilities and informs appropriate safety-factor selection.
