Since women's participation is crucial in promoting more extensive and sustainable aquaculture, this paper presents a gender monitoring schema for aquaculture to allow for women's meaningful participation. A review of current MEL systems, particularly in aquaculture, found that the plethora of gender indicators and MEL frameworks do not adequately capture the dynamics of changes in gender roles and relations. Given that shifts in gender relations can be subtle, the change process is crucial to capture so that the MEL process can further accelerate these shifts within the lifetime of the project itself. Noting that women's important role in extensive and sustainable aquaculture, for e.g., nature-based solutions (NbS), the MEL process focusing on NbS aquaculture has been developed. Three agentic processes (awareness, images of change, and agency) and two environmental processes (attitudes towards NbS practices and climate change) have been identified as the key domains for the proposed gender monitoring schema to capture the process of change towards gender equality in the context of climate change.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"609 ","pages":"Article 742776"},"PeriodicalIF":3.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the application and advantages of a target-activatable aptamer probe (TAA-Q2c2) in the identification of SGIV were investigated. First, the specificity of TAA-Q2c2 was established for SGIV. Then, the optimal experimental conditions were determined to be a working concentration of 500 nM, an incubation temperature of 4–28 °C, and an incubation time of 1 min. The detection sensitivity was comparable to that of RT-qPCR at approximately 103 SGIV-infected cells/mL; however, the activatable probe is more suitable for aquaculture field applications, and detection can be completed in less than two hours. In conclusion, TAA-Q2c2 enables the rapid and specific detection of SGIV, and is a promising new tool for the early detection of virus infection in aquaculture.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"609 ","pages":"Article 742768"},"PeriodicalIF":3.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the decapod iridescent virus 1 (DIV1) has garnered significant attention for causing mass mortality events in crustaceans. The epidemiological investigation revealed a high prevalence of DIV1 in cultured mud crabs. Therefore, understanding the susceptibility of mud crabs to DIV1 is crucial for raising awareness among farmers and mitigating economic losses from potential outbreaks. Experimental infections with DIV1 showed 100 % mortality in intramuscularly injected (IM group) crabs and 60 % in those given oral administration (PO group). Nested PCR confirmed that mud crabs from both groups were positive for DIV1 and significantly elevated DIV1 loads in these mud crabs. Histopathological analyses revealed the presence of eosinophilic and basophilic inclusions in the hepatopancreas, muscle, gill, and stomach tissues of DIV1-infected mud crabs, while transmission electron microscopy (TEM) revealed numerous viral particles in the host cell cytoplasm. Notably, in addition to exhibiting symptoms like slow response and loss of appetite, some infected crabs exhibited distinctive body reddening, possibly a unique symptom of DIV1 infection in mud crab. The lethal dose 50 (LD₅₀) test demonstrate that DIV1 is highly virulent to mud crabs. It was also observed that DIV1 replicated extensively in various tissues of mud crabs resulting in severe tissue damage. These findings demonstrate that mud crabs are susceptible hosts of DIV1, and DIV1 is highly pathogenic to them. Furthermore, the study highlights the risk of cross-species transmission in polyculture systems, as healthy <em>Litopenaeus vannamei</em> can contract DIV1 from infected mud crabs. These results emphasize the necessity for enhanced monitoring and control measures for DIV1 in mud crab farming to prevent viral outbreaks effectively.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"609 ","pages":"Article 742778"},"PeriodicalIF":3.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144204480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the group administered 62 μM RD, viral plaque-forming units and gene quantity were significantly reduced compared to the control group, and no viral amplicons were synthesized following RT-PCR. In fish, intravenous injections are impractical due to their small size and thin blood vessels; thus, RD was administered intramuscularly. In olive flounders infected with VHSV, RD administration resulted in lower cumulative mortality rates across all RD-administered groups than in the control. The group administered 0.25 mg/kg RD showed the highest survival rate, over twice that of the control group.
