The Chinese Academy of Fishery Sciences (CAFS) (simplified Chinese: 中国水产科学研究院; traditional Chinese: 中國水產科學研究院; Pinyin: Zhōngguó shuǐchǎn Kēxuéyánjiūyuàn) is a large fisheries research institute. It was founded in 1978 under the Ministry of Agriculture in the People's Republic of China. It is a leading research institution in China, active in almost all research areas to do with aquaculture and marine and freshwater fisheries.CAFS sponsors the award-winning international academic periodical Journal of Fishery Sciences of China. It has completed over 1,000 research projects, including a study on the aquaculture of the fleshy prawn Peneaus chinensis and the control of haemorrhage disease in grass carp, which won the National Scientific and Technological Progress First Prize. The institute has contributed significantly to China's aquaculture development.
Large Language Models (LLMs) are increasingly used across many scientific domains, but their role in fisheries management research remains poorly defined. Here we provide an evidence-based overview of how LLMs might be used, and what risks they introduce, in fisheries management research. First, we review documented and emerging applications of LLMs across four main research tasks in fisheries science: literature review and knowledge synthesis, data collection and processing, developing and evaluating models, and science communication and stakeholder engagement. We then draw on selected examples from ecology, environmental science, and oceanography to identify potentially transferable applications and research gaps relevant to fisheries. Viewed in this cross-disciplinary context, fisheries have already begun to apply LLMs in data focused tasks, whereas applications for modeling support and stakeholder communication are still mostly at a conceptual stage. Second, we synthesize technical, operational, legal and compliance, and ethical and societal risks that are particularly relevant to fisheries, and outline practical options for mitigation. Based on this analysis, we propose a six-step, risk-aware workflow for incorporating LLMs into fisheries research and advisory processes as supporting tools rather than as autonomous decision makers. Our aim is to help fisheries scientists, managers and policymakers explore LLMs in a cautious and transparent way, so that the benefits to sustainable fisheries management are realized without undermining scientific integrity or trust.
To evaluate the effects of substituting soybean oil (SO) with soy lecithin (SL) and specialty lipid (CL) on the growth, body composition, and glucose-lipid metabolism of juvenile largemouth bass (Micropterus salmoides). The CL is a composite lipid source formulated by mixing coconut oil, linseed oil, soy lecithin oil, and palm oil in a ratio of 2:2:3:3, with the addition of antioxidants and emulsifiers as fillers. A total of six experimental groups were established: an iso-nitrogenous and iso-lipidic soybean oil (SO) (control group), a 1
Acute hepatopancreatic necrosis disease (AHPND) is a fatal disease caused by Vibrio parahaemolyticus, which severely impacts the crustacean aquaculture industry. In this study, we focused on the economically important Portunus trituberculatus, and investigated the differences in disease resistance among domesticated populations and its genetic basis using artificial infection experiments and resequencing analysis. A 12-day V. parahaemolyticus (5.6 × 106 CFU/mL) challenge experiment involving 1,000 crabs identified a subset of highly resistant individuals. Whole-genome resequencing of the high-resistant and normal populations generated a total of 1,261 Gb of sequencing data, achieving an average depth of 14.43×. Population structure and selective sweep analyses identified 96 candidate regions and 244 candidate genes, including Serpin B1 and Croquemort. KEGG enrichment analysis revealed that the candidate genes were significantly enriched in signaling pathways related to bacterial infections, including Salmonella infections, bacterial invasion of epithelial cells and phagolysosomes. Notably, genes from the actin family emerged as central components within these pathways, suggesting their pivotal role in mediating immune responses in the highly resistant population. These findings provide exploratory genomic evidence and candidate resources for future functional validation and disease-resistant breeding.
Aeromonas hydrophila (A. hydrophila) is widely spread in different aquatic environments and still poses a serious threat to the health of aquatic animals. Nevertheless, with the emergence of drug-resistant A. hydrophila, antibiotics have shown limited efficacy as primary therapeutic agents, and novel treatment strategies are urgently needed. The increasing understanding of anti-virulence and anti-quorum-sensing (QS) strategies offers new hope for drug discovery against A. hydrophila infections, which aim not to inhibit or kill bacteria but to reduce pathogenicity by reducing the production or activity of virulence factors. Here, xanthoxylin was screened out, and some tests were conducted on virulence phenotypes and therapeutic effects; the results demonstrated that xanthoxylin lacked anti-A. hydrophila effect could reduce the levels of QS-mediated virulence factors and the transcription of the aerA, ahyR, and ahyI genes. Further therapeutic results showed that xanthoxylin could protect A549 cells from cytotoxicity induced by aerolysin and improve the survival rate of crucian carp (Carassius auratus gibelio) challenged with A. hydrophila. Therefore, xanthoxylin could be a potential QS inhibitor for controlling A. hydrophila infections in aquaculture.
To investigate the cause of the large-scale death of farmed bullfrog (Lithobates catesbeianus) in a certain area of Hubei Province. Bacterial isolates were revealed from the liver, brain, and lung of bullfrogs exhibiting typical symptoms of cataract. Regression infection studies confirmed that a strain Z20240301 was responsible for the white eyes and high mortality rate among bullfrogs. Histopathological analysis revealed that the infection could lead to varying degrees of hemorrhage in the meningeal connective tissue of the bullfrogs. The further 16S rRNA sequence identification and Genome-wide analysis confirmed that the Z20240301 belongs to Acinetobacter johnsonii, which carries 566 virulence factor-related genes, include hlyA, hlyB, and lipopolysaccharide (LPS); and 257 drug resistance-related genes, including those conferring resistance to major antibiotic classes such as macrolides, aminoglycosides, fluoroquinolones, and tetracyclines. The isolate Z20240301 was highly sensitive to cefazolin oxime, cefradine, gentamicin, streptomycin, netilmicin, and tobramycin; moderately sensitive to cefotaxime, azithromycin, erythromycin, enrofloxacin, doxycycline, and neomycin; and resistant to enoxacin, norfloxacin, and kanamycin. This study is the first to confirm A. johnsonii as a causative agent of cataracts in bullfrogs, providing a new theoretical basis for the diagnosis, prevention, and treatment of this disease.
