河口是营养丰富的环境，具有淡水到盐水的梯度。它们支持高初级生产力和丰富的浮游动物。河口被许多鱼类用作育苗场，因为它们的环境条件为幼鱼和成鱼提供了丰富的食物。鱼类浮游生物包括鱼卵和仔鱼，对鱼类的补充很重要。目前，还没有从全球角度对河口鱼类浮游生物进行系统评价。本文对近60年来（1951-2022年）鱼类浮游生物的研究进行了综述，主要从3个方面进行了分析：鱼类浮游生物研究成果的评价、鱼类浮游生物群落结构以及影响鱼类浮游生物群落结构的因素。结果表明，河口鱼类浮游生物的研究有所增加，从20世纪50年代的每年不到1篇文章增加到21世纪20年代的每年30多篇文章。最常用的关键词是“社区结构”和“动态”，最近使用的词是“气候变化”。关于河口鱼类浮游生物研究的地理分布，美国最多（占所有研究的32.9%），其次是澳大利亚（8.1%），南非（6.1%），巴西（5.6%），日本（5.1%），中国（4.9%），加拿大（4.8%）和葡萄牙（4.8%）。盐度和浊度是影响河口鱼类群落结构的主要因素。气候变化通过改变物种的产卵时间、产卵地点和孵化时间间接影响河口鱼类浮游生物群落结构。产卵场向极地移动与产卵时间提前的趋势一致。此外，DNA条形码技术的发展将是对传统鱼类浮游生物分类鉴定方法的有益补充，并将为该领域系统分类学的发展提供新的机遇。本文的综述有助于加深对河口鱼类浮游生物的认识，为河口环境保护和河口渔业资源的可持续利用提供理论支持。
Estuaries are nutrient-rich environments with a gradient of fresh to salt water. They support high primary productivity and an abundance of zooplankton. Estuaries are used by many fish as nursery grounds because their environmental conditions provide abundant food for larval and adult fish. Ichthyoplankton, which comprise fish eggs and larvae, are important for the recruitment of fish species. At present, there are no systematic reviews on ichthyoplankton in estuaries from a global perspective. Here, research on ichthyoplankton over the last 60 years (1951–2022) was reviewed, focusing on three aspects: evaluation of ichthyoplankton published studies, community structure, and factors affecting community structure. The results show that research on estuarine ichthyoplankton has increased, from less than 1 article per year in the 1950s to more than 30 articles per year in the 2020s. The keyword used most commonly was ‘community structure’ and ‘dynamics’ and the word used most recently was ‘climate change’. Regarding the geographical distribution of the studies carried out on estuarine ichthyoplankton, USA had the most (32.9% of all studies), followed by Australia (8.1%), South Africa (6.1%), Brazil (5.6%), Japan (5.1%), China (4.9%), Canada (4.8%), and Portugal (4.8%). Salinity and turbidity were the main factors affecting the ichthyoplankton community structure in estuaries. Climate change indirectly affected the community structure of estuarine ichthyoplankton by changing the spawning time, spawning location, and hatching time of species. The movement of spawning sites poleward and the advance of spawning time showed a consistent trend. In addition, the development of DNA barcoding techniques will be a useful supplement to traditional taxonomic methods for identifying ichthyoplankton and will provide new opportunities for the development of systematic taxonomy in this field. Our review contributes to a broader understanding of estuarine ichthyoplankton and provides theoretical support for estuarine environmental protection and the sustainable use of estuarine fishery resources.
