Scope
Aims, scope and focus
Knowledge and Management of Aquatic Ecosystems is published by EDP Sciences and is in Zone 4 of Environmental Science & Ecology in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Fish Ecology and Management Studies, Aquatic Invertebrate Ecology and Behavior and Fish Biology and Ecology Studies, together about 38.8% of its articles. Its main subfields are Ecology. (generated from OpenAlex topic counts and CAS ranking data)
Knowledge and Management of Aquatic Ecosystems (KMAE-Bulletin Français de la Pêche et de la Pisciculture since 1928) serves as a foundation for scientific advice across the broad spectrum of management, conservation and restoration issues related to inland aquatic ecosystems (including their intermittent states and adjacent systems like riparian or hyporheic zones), such as springs, streams, rivers, floodplains, lakes, ponds and wetlands. Knowledge and Management of Aquatic Ecosystems publishes novel, broad-reaching papers on the interface between changes in the physical, chemical and biotic aspects of the freshwater environment and their consequences for biological communities (e.g., micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates) and ecosystems functioning (e.g., productivity, food-webs, decomposition rates). Knowledge and Management of Aquatic Ecosystems approaches all major themes in applied ecology, such as conservation biology, physical environmental degradation and pollution, climate change, restoration ecology, and the management of invasive species and diseases. In that, the journal aims to improve the scientific understanding of freshwater ecosystems degradation and to provide science-based solutions for an effective conservation and management of freshwater habitats, species and ecosystem functioning. Its scope also includes economic and social studies (including cultural, philosophical, political, educational and historical aspects), in so far as they are directly concerned with the management of freshwater ecosystems and prove of general interest to freshwater specialists, stakeholders, managers and policy makers. Contributions are welcome from a wide geographical range to ensure a broad representation of freshwater ecosystems environmental degradation, conservation and restoration issues across the globe. KMAE considers as suitable the contributions based on traditional approaches (e.g. empirical surveys, experimental approaches, literature-based surveys), as well as those based on emerging technologies (e.g., environmental DNA, genetic and genomic analyses, remote sensing analyses). Purely descriptive or fundamental manuscripts without a clear link with applied ecology and evolution are unlikely to be considered in KMAE. Quite the reverse, studies linking anthropogenic disturbances or restoration efforts to changes in biological communities are highly welcome. Research into the following areas may be published
