Fucosterol, a bioactive compound isolated from brown marine algae, has been reported to exhibit various pharmacological properties, including anti-inflammatory activity. However, further investigation is needed to elucidate its mechanisms of action. This study assessed the anti-inflammatory potential of fucosterol using in silico, in vitro, and in vivo approaches. Reverse molecular docking revealed strong binding affinities with interleukin (IL)-6 (–6.3 kcal/mol) and IL-1β (–7.4 kcal/mol), suggesting potential interactions with key inflammatory cytokines. Moreover, absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling highlighted fucosterol’s favorable drug-likeness and toxicity profile. Toxicity assessments, including the MTT assay on Human Embryonic Kidney (HEK293) cells and the zebrafish embryo acute toxicity assay, showed concentration-dependent effects, with half-maximal inhibitory concentration (IC50) and medial lethal concentration (LC50) values of 279.90 μg/mL and 173.60 μg/mL, respectively. In vitro Enzyme-Linked Immunosorbent Assay (ELISA)-based assay using lipopolysaccharide-induced HEK293 cells demonstrated a biphasic response in inhibiting IL-6 (24 and 48 h IC50 = 5.86 and 73.36 μg/mL) and IL-1β (24 and 48 h IC50 = 2.59 and 0.02 μg/mL). Similarly, in vivo analysis using lipopolysaccharide-induced zebrafish embryos showed a significant reduction in IL-6 (24 and 48 h IC50 = 34.54 and 30.28 μg/mL) and IL-1β (24 and 48 h IC50 = 29.39 and 29.61 μg/mL) at higher concentrations. These findings provide valuable insights into fucosterol’s role in modulating inflammatory cytokines, likely through the NF-κB pathway. The study provides a better understanding of fucosterol’s anti-inflammatory mechanisms, supporting its potential for further pharmacological research. Future studies, including clinical validation and mechanistic studies, are necessary to establish its therapeutic use and application.","PeriodicalId":12249,"journal":{"name":"Fisheries and Aquatic Sciences","volume":"28 10","pages":"687-704"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e-fas.org/download/download_pdf?pid=fas-28-10-687","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparative analysis of single-injection and double-injection spawning methods was conducted, along with evaluating common carp (Cyprinus carpio) as initial feed. The results revealed significant differences in effect duration, with natural spawning (37.2 ± 0.8 h) being the longest, followed by the one-injection method (24.5 ± 0.5 h), and the two-injection method (18.5 ± 0.5 h). Fertilization rates also differed significantly, with the one-injection (81.33 ± 2.40%) and two-injection methods (83.03 ± 2.41%) outperforming natural spawning (73.50 ± 3.75%). The growth curves of both common carp and mandarin fish displayed nonlinear trends over time, supporting the feasibility of using common carp as an initial feed for mandarin fish. The industrial aquaculture model successfully maintained high water quality, highlighting its effectiveness in water purification. After 60 days of domestication, 91,819 juvenile mandarin fish with an average size of 7.8±0.15 cm were harvested, achieving a feed conversion ratio of 2.2 and a survival rate of 18.65%. This study demonstrates the potential for large-scale aquaculture and industrial development of mandarin fish in northern China, providing valuable insights into improving breeding and acclimation processes.","PeriodicalId":12249,"journal":{"name":"Fisheries and Aquatic Sciences","volume":"28 7","pages":"491-500"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e-fas.org/download/download_pdf?pid=fas-28-7-491","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
