A theoretical analysis of the harvesting roller brush was conducted, resulting in the derivation of key structural and operational parameter ranges. The Discrete Element Method (DEM) combined with Multi-Body Dynamics (MBD) was employed to simulate single-factor tests, Plackett-Burman tests, and response surface tests in shellfish harvesting. The optimal combination of key structural and operational parameters for the harvesting roller brush was identified as follows: bristle length of 105 mm, 5 bristle rows, bristle thickness of 40 mm, spiral angle of 28°, rotation speed of 48 r/min, and installation positions at X-axis 249 mm and Y-axis 9 mm. Under these conditions, the average mass of residual sediments on the screen surface was 10.59 g, the harvested shellfish mass was 177.4 g, and the shellfish breakage rate was 11.10 %. A prototype shellfish harvester was developed, and field tests demonstrated a harvested shellfish mass of 166.2 g, with a relative error of 8.57 %, a shellfish breakage rate of 7.07 %, an absolute breakage rate error of 4.03 %, and a harvesting efficiency of 292.20 kg/h.

However, existing counting methods struggle to address challenges, such as fish overlap and scale variations in the presence of complex background noise. Therefore, this study proposes a CNN-based accurate fish-counting framework. The front-end network uses the first ten layers of VGG 16 to extract the main feature information. The framework first uses a multi-scale feature perception module and four parallel-dilated convolutional networks. Each dilated convolution uses a dilated convolution with a different dilation rate to extract diverse features from the image and adapts to scale changes. Second, to reduce the occlusion problem in counting, an adaptive global perception module was designed to optimize the focus on occluded areas through information interactions between channel features. Finally, an edge excitation module was designed to reweight the features in the channel through a parallel structure using two convolutional approaches, thereby enhancing the edge feature extraction. This module addresses the issue of neglecting edge pixels, improving the model’s ability to process edge features, and reducing interference from complex background noise. Experimentally, the MAE and RMSE of the model on the carp count dataset (CCD) were 2.64 and 3.58, respectively. The average counting accuracy was 94.76%. For the dense grass carp counting dataset (DGCD), the average counting accuracy of model was 96.96%. The model performed well in terms of counting accuracy and showed good stability.

The fish spawn in the containers, and the eggs are usually removed and incubated indoors. Currently, at the Warmwater Aquaculture Research unit (Stoneville, MS) fish biologists are using round polytanks placed on the pond bank for spawning container placement with pond water pumped through the tank and aeration diffusers in the tanks to assure the pond water is well oxygenated. Depending on how and where the water is obtained from in the pond there can be a heavy solids loads associated with the incoming water. A hydrocyclone was evaluated as a simple and easily managed unit to reduce the solids load of the incoming water flow. The pond water flowed to a line of one hundred polytanks (1.5 m Ø, 1.5m³). The mean total suspended solids (TSS) concentration in the incoming pond water ranged from 26.3 to 37.1 mg/L. Mean daily single pass solids removal rates were compared at four different flow rates, 114 lpm, 170 lpm, 227 lpm, and 303 lpm (30, 45, 60, and 80 gpm, respectively). The pump output flow was limited by the suction pressure of the water flow from the in-pond floating skimmer and the reduced diameter (3.18 cm) of the inlet pipe to the pump intake. The mean single pass solids removal efficiency, RE (%)from four consecutive days of sampling at each flow rate (n = 4) ranged from 12.0 % at 114 lpm to 23.9 % at 303 lpm. Removal rates increased with increasing flow but the test statistic with α at 0.05 indicated no observable significant difference. The mean amount of solids from the hydrocyclone underflow purge volume ranged from 24.4 g at 114 lpm to 31.6 g at 170 lpm. Significant greated solids amount were observed (α at 0.05) in the purge volumes at te 170 and 227 lpm flow rates, respectively.

The strongest constrictions to aquaculture of <em>L. digitata</em>, <em>S. latissima</em> and <em>P. palmata</em> were caused by wave height and current speed. Among the studied species, <em>S. latissima</em> showed the largest suitable area for development (up to 1847 km²), while <em>P. palmata</em> presented the smallest area with 461 km².

Previous studies have identified favorable conditions and potential hotspots for H₂S production in RAS under mixed reactors conditions, but knowledge on temporal and spatial dynamics of H₂S production within layers of accumulated organic matter within these systems remains limited. In this study, we investigated H₂S production dynamics at fine spatial (millimeter) and temporal (hourly) scales in accumulated marine and freshwater organic waste collected from RAS, using a high-resolution microsensor setup. In addition to measuring the natural H₂S production potential, we examined the response to the addition of readily available carbon sources and sulfur-rich amino acid cysteine, as well as the microbial communities present in organic waste. In both freshwater and marine organic waste, H₂S appeared only within one centimeter of the accumulated fish organic waste after oxygen was consumed. When this organic waste was disturbed, the accumulated H₂S was rapidly released into the water column and reached concentrations above the toxicity threshold for fish. Through a combination of carbon and cysteine supplementation and 16S rRNA gene analysis, we identified cysteine degradation and sulfate reduction as key microbial pathways for H₂S production in the accumulated organic waste. Overall, this study demonstrates that hydrogen sulfide can form within very thin layers of accumulated fish organic waste in both freshwater and saltwater environments and once released, can reach toxic levels for fish. Therefore, it is crucial to focus on minimizing organic matter accumulation in RAS and implementing contingency measures when the bottom of tanks is disturbed.</div></div>","PeriodicalId":8120,"journal":{"name":"Aquacultural Engineering","volume":"111 ","pages":"Article 102578"},"PeriodicalIF":3.6,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178267","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}

This project assessed the effects of two types of RAS: clear water (CW) and hybrid (HY), along with horizontal substrate, on intensive Pacific White Shrimp production and water quality. In CW RAS a very clean environment is created using a series of filters, but the technique may have relatively high equipment costs. More simplistic HY systems have external biofilters to cycle nutrients, but solids filtration is relatively minimal. Horizontal substrate may help to enhance shrimp production by increasing the surface area for shrimp to graze and escape competition. In this study, two levels of each experimental factor were used: system type (CW vs HY) and systems with substrate (WS) versus those with no substrate (NS). There were four treatments: HY-WS, HY-NS, CW-WS, and CW-NS, each of them with four replicates randomly assigned to 1-m³ circular tanks. Shrimp with an average weight of 1.3 g were stocked at a density of 450 m⁻³ and reared for 53 days. The HY-WS treatment resulted in significantly higher individual shrimp weight, total biomass harvested (7 kg m⁻³), survival, and growth rate compared to the HY-NS and CW-NS treatments. The CW-WS treatment was not significantly different than HY-WS or HY-NS treatments with regard to these parameters. TAN and nitrite-N were significantly lower in HY systems and those systems that contained substrate. The CW-NS treatment had a very high nitrite-N concentration. This resulted in low survival and may have been due to excess ozone entering the biofilters in the CW treatments and killing the nitrifying bacteria.

This study evaluated aerobic digestion as a treatment strategy for solid organic waste generated in recirculating aquaculture systems (RAS) for African catfish (<em>Clarias gariepinus</em>), with the aim of optimizing operational conditions for maximum nutrient mineralization and recovery. A multifactorial experiment was conducted using four treatments (control, pH 6, pH 7, bacterial inoculation), each tested at three temperatures (20, 25, 30 °C) in triplicate (36 reactors in total). Each reactor was loaded with 10 g of freeze-dried sludge and 1 L of water or phosphate buffer. Digestion proceeded for 21 days. The most effective condition was the control treatment at 30 °C without pH adjustment or bacterial inoculation. Under this setting, the final nitrate concentration reached 81.4 mg/L. Phosphorus recovery efficiency (NRE) was 61.1 %, and potassium recovery reached 76.8 %. The final nutrient solution had a favorable NO₃⁻:NH₄⁺ ratio of 75:25. Higher temperature promoted nitrification and overall mineralization. Acidified conditions (pH 6) enhanced ammonium and phosphorus solubilization but slowed nitrate formation. The addition of external bacteria did not improve mineralization efficiency, likely due to microbial competition or limited inoculum performance. Heavy metals were below detection limits. However, persistent nitrite concentrations (∼4–5 mg/L) and poor solubilization of micronutrients, especially Fe and Zn, remain limitations. Laboratory-scale pretreatment (freeze-drying and milling) may have improved solubility compared to raw sludge and should be considered when interpreting results.
