摘要

大甲壳类动物需要海洋、河口和河流之间的连通性来完成其生命周期。河流下游的河流屏障威胁着双生大型甲壳类动物的上游迁徙。黄貂鱼在海上产卵后向上游迁移。这些迁移事件没有得到很好的记录。在2021-2022年期间，我们在南非夸祖鲁-纳塔尔省下图克拉河散装供水计划堰的一个垂直槽鱼道和一个岩石坡道上记录了V. litterata和Macrobrachium spp.的存在。我们发现巨臂目(Macrobrachium sp .)和V. litterata利用了岩石坡道。然而，与其他研究一样，垂直槽型鱼道确实显著地阻碍了白桦尺蠖的迁徙。

The migration of aquatic macrocrustaceans over an artificial barrier in the uThukela river, South Africa

Diadromous macrocrustaceans need connectivity between the ocean, estuary and river to complete their life cycle. Instream barriers in lower reaches of rivers threaten upstream migrations of diadromous macrocrustaceans. Varuna litterata migrate upstream after a spawning event out at sea. These migration events have been poorly documented. We documented the presence V. litterata and Macrobrachium spp. at a vertical slot fishway and a rock ramp on the Lower Thukela River Bulk Water Supply Scheme Weir, KwaZulu-Natal, South Africa, during 2021–2022. We found Macrobrachium spp. and V. litterata made use of the rock ramp. However, the vertical slot fishway did hinder the migration of V. litterata significantly, as found in other studies.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
