The study assessed the water quality parameters, growth performance, proximate and biochemical composition of the organisms undergoing the different treatments. Moreover, they were compared with outdoor farmed seaweeds and oysters to assess their nutritional quality. Significant variations were seen in the growth rates of the two seaweeds, <i>U. lactuca</i> exhibiting the highest live weight gain (LWG) and specific growth rate (SGR) in coculture settings. The percentage of surviving oysters varied from 60% to 80% across experiments, with the fastest growth rates observed when cocultured with <i>U. lactuca</i>. The seaweeds’ moisture, ash, protein, carbohydrate, and fiber contents varied significantly, with <i>U. lactuca</i> (indoor) having the highest protein and carbohydrate content (<i>p</i> &lt; 0.05) compared to <i>U. lactuca</i> (outdoor) and <i>G. verrucosa</i> (indoor and outdoor), and also recording the maximum total chlorophyl, carotenoids, and fucoxanthin. Significant variations were found in the fatty acid content of seaweed and oyster samples. Outdoor oyster samples had more omega-3 fatty acids (<i>p</i> &lt; 0.05) than indoor while the indoor seaweed samples had lower saturated fatty acids (SAFA), and higher polyunsaturated fatty acids (PUFA) than outdoor. <i>U. lactuca</i> grown indoors exhibited the highest levels of both essential amino acids (EAAs) and non-essential amino acids (NEAAs). The study emphasizes how culture conditions affect the nutritional and biochemical profiles of seaweeds and oysters, and it offers indoor coculture as a potential substitute for inclement environmental conditions and as a backup strategy to enhance sustainable seaweed mariculture that allow for optimal growth and nutritional quality ensuring the maximum space utilization.</p>\u0000 </div>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2025 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/6901843","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tenacibaculosis, caused by species of Gram-negative bacteria in the genus <i>Tenacibaculum</i>, has the potential to be transmitted interchangeably between farmed Atlantic salmon and wild Pacific salmon, though there is a lack of corroboration establishing transmission. To provide evidence for interspecific horizontal transmission of tenacibaculosis from Atlantic salmon to Pacific salmon, Atlantic salmon were bath-exposed to an isolate of <i>Tenacibaculum maritimum</i> and cohabitated with naïve Atlantic or Chinook salmon (<i>Oncorhynchus tshawytscha</i> W.) for 25 days. Exposed and naïve cohabitant Atlantic salmon exhibited morbidity with multifocal superficial and ulcerative epidermal lesions with intralesional <i>T. maritimum</i> (culture, histology, and qPCR). At 10⁸ CFU mL⁻¹, exposed and naïve cohabitant Atlantic salmon had 43% and 60% mortality, respectively. Contrastingly, cohabitant Chinook salmon experienced no morbidity or mortality, despite successful culture of <i>T. maritimum</i> (10⁸ CFU mL⁻¹<i>n</i> = 5/6 fish; 10⁶ CFU mL⁻¹<i>n</i> = 0/6 fish) from skin swabs. These findings suggest that BC Chinook salmon do not develop clinical tenacibaculosis through interspecific horizontal transmission from farmed Atlantic salmon with mouthrot under the tested conditions and that the presence of <i>T. maritimum</i> alone is insufficient for disease. Further research needs to clarify the genetic differences between hosts and pathogens in different geographical locations, and investigate additional <i>T. maritimum</i> isolates, alternative <i>Tenacibaculum</i> species, environmental variables, and temporal scales that could lead to clinical tenacibaculosis in Chinook salmon.</p>\u0000 </div>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2025 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/3544576","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a gilthead seabream (<i>Sparus aurata</i>) larvae trial, we compared four novel feeding regimes to the standard diet (Std-Art), which included consecutive feeding of <i>Brachionus plicatilis</i> (Rot) and <i>Artemia salina</i> (Art) from 4 days post-hatching (dph) until weaning at 32 dph, followed by microdiet (MD) until 56 dph. All newly formulated feeding regimes included MD mostly from first-feeding, with variations in live feeds provided. The first regime included initial consecutive feeding of <i>Acartia tonsa</i> nauplii (Cop) and then <i>Artemia</i> until weaning at 26 dph (MDe-Cop-Art). The second regime involved rotifer feeding until 20 dph (MDe-Rot), while the third provided <i>A. tonsa</i> until 20 dph (MDe-Cop). The fourth regime featured consecutive feeding of two copepods species, the regularly used <i>A. tonsa</i> and a newly tested tropical species, <i>Apocyclops panamensis</i> (from nauplii to copepodite) until 20 dph, introducing MD at 18 dph (MDa-2Cop). The MDe-Cop-Art regime substantially outperformed all other regimes in survival rate (37.5% ± 2.7% vs. 21.1% ± 2.7% of Std-Art) and total biomass production per tank (69 ± 7 g vs. 16 ± 7 g of Std-Art). This highlights the advantage of feeding copepods over rotifers and emphasises the importance of a short <i>Artemia</i> inclusion, potentially improving feeding activity, digestion and assimilation. Co-feeding live feed with MD from first-feeding was found to enhance growth and survival, indicating the progressive adaptation of larvae to the physical and biochemical characteristics of the MD. This adaptation likely promoted earlier maturation of the digestive system and improved nutrient uptake and utilisation.

Stakeholders emphasize research is needed to understand aquaculture’s functions at household and farm scales. Innovations to improve productivity must consider agroecological contexts, local knowledge, and adaptations to situate aquaculture within local livelihood. A study was conducted in Luwingu District to assess productivity and understand farmer perceptions. Data collection (Oct–Dec 2021) engaged fish farmers (<i>n</i> = 63) in surveys, farm appraisals, and discussions. Qualitative data highlighted farmers’ perspectives, and thematic review identified their major challenges. Quantitative data described household demographics, priorities, resources, and management systems. Multivariate techniques (principal components analysis [PCA]) assessed variation within the sample, reduced data complexity, and created sets of composite variables describing system inputs. Multiple linear regression tested effects of inputs on pond productivity (kg Fish m⁻²); and stepwise elimination identified key factors. Results indicated that farmers considered aquaculture a secondary economic activity, contributing an average of only 9% ± 12% to household income. Most farmers used household labor, basic tools, and crop waste as inputs. The mean output (1.2 ± 1.2 t fish ha⁻¹) was low. Predictive models indicated household wealth, education, farm size, intensity of feed, fingerling and labor inputs, fish growth cycles, and spatial integration with cropland were most associated with aquacultural productivity.

As the use of ZnO NPs grows, there are rising concerns about their potential environmental impacts, particularly on aquatic ecosystems. When released into water bodies, these NPs can be ingested by aquatic organisms, leading to bioaccumulation and potential toxicity. Therefore, understanding their effects on aquatic species, like <i>C. carpio</i>, is crucial. Significant alterations in the erythrocyte count, hemoglobin (Hb), and hematocrit (Ht) levels were found. Compared to the control group, the number of lymphocytes, EOSO, monocytes, and platelets in the Zn NPs-exposed groups dramatically increased. The biochemical analysis found considerable changes in blood total protein, albumin, globulin, and glucose levels. Histological examinations of the gills, intestines, and kidneys were conducted to assess structural or pathological changes. Treated fish showed progressive architectural distortions like necrosis (N), hyperplasia (HP), hypertrophy (HT), fusion of gill lamella (FGL), and proliferation of mucocytes (PM) in gills. Distension of the intercellular space (DIS), increased rate of the mucous cell (IMC), villous atrophy (VA), HP, and dysplasia (DP) were found in the intestines of ZnO NPs treated <i>C. carpio</i>. Tubular dilatation, tubular necrosis, severe congestion, hematopoietic tissue degradation, constricted lumen, glomerulopathy, and bowmans capsule dilution in kidneys of ZnO NPs treated <i>C. carpio</i> were noted. The findings from this study shed light on the biochemical and histological effects of ZnO NPs on <i>C. carpio</i>, contributing to a better understanding of the potential risks associated with NP exposure in aquatic environments.
