In recent years, aquaculture is considered a fastest‐blooming global food industry, playing a crucial role in fulfilling the increased demand for animal protein requirements. However, disease prevalence, chemical contamination, environmental degradation and ineffective feed utilization are the factors that drastically hinder the outcome of this sector in aiding to achieve global food security. In this regard, new avenues have been paved in science and technology to cope with these challenges in aquaculture. Among these, nanotechnology has emerged a tremendous potential to improve aquaculture with novel nanotools. This review critically analyses the advances in the application of nanoparticles and emulsion‐based systems to fish disease prevention, water purification and delivery of nutrients. On the other hand, as the use of antibiotics and other chemical antimicrobial agents, synthetic compounds as growth enhancers not only leads to aquaculture pollution but also consumer's reluctance. Therefore, the importance of ecofriendly, non‐toxic natural strategies to promote sustainable aquaculture has also been highlighted.

纳米技术在可持续水产养殖和渔业方面的进展

近年来，水产养殖被认为是全球食品业发展最快的行业，在满足对动物蛋白质需求不断增长的需求方面发挥着至关重要的作用。但是，疾病流行，化学污染，环境恶化和饲料利用不充分是严重阻碍该部门实现全球粮食安全的结果的因素。在这方面，已经为科学和技术开辟了新途径，以应对水产养殖中的这些挑战。其中，纳米技术已经出现了巨大的潜力，可以通过新型纳米工具改善水产养殖。这篇评论严谨地分析了纳米颗粒和基于乳液的系统在鱼类疾病预防，水净化和营养输送中的应用进展。另一方面，作为抗生素和其他化学抗微生物剂的使用，合成化合物作为生长促进剂不仅导致水产养殖污染，而且还导致消费者不情愿。因此，还强调了生态友好，无毒的自然策略对促进可持续水产养殖的重要性。
