The MFADWS, extending from Murchison Falls to the Albert Delta in Uganda, supports diverse species, including fish, birds, reptiles, amphibians and mammals, all of which are vital to the livelihoods of surrounding communities. Sampling was conducted in three sections: upstream (Zipper), midstream (Delta) and downstream (Lake Albert) from April 2013 to March 2014 and October 2017 to September 2018. A total of 52 fish species were recorded, with the Zipper and Delta exhibiting greater diversity compared to Lake Albert. Among the recorded species, 43 were classified as Least Concern, seven as Not Evaluated, two as Data Deficient and one (<i>Lates macrophthalmus</i>), endemic to Lake Albert as vulnerable. The Shannon-Weaver diversity index (H′) was highest in the Zipper (3.4 ± 009), followed by the Delta (2.94 ± 0.31) and lowest in Lake Albert (2.19 ± 0.0). The higher biodiversity in the Zipper and Delta underscores the ecological significance of these protected areas. However, the study identified potential threats to the fish biodiversity, including illegal fishing, invasive aquatic weeds and the expansion of oil and gas developments in the Albertine Graben. To safeguard the region's biodiversity, strict enforcement of existing regulations, strengthened monitoring, control and surveillance measures, implementation of biodiversity action plans and protection of critical fish habitats are proposed, to balance biodiversity conservation with local livelihoods and economic developments.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143889077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2021, the Taoyuan Algal Reef in Taiwan became a national focus during a referendum, yet public understanding of its ecology remained limited. To bridge this gap, we partnered with nearby residents to conduct a coastal habitat survey using a simple, standardized data collection method. Participants received training, and even after our team concluded the project, locals continued monitoring independently using the same method. To verify the reliability of data collected with and without scientific supervision, we compared the datasets statistically using coefficients of variation. Results showed no significant differences, demonstrating that independently collected data were reliable. This enabled us to combine the datasets for further biodiversity analysis, examining organism abundance, species richness, and the Shannon index. Findings revealed that pebble habitats had the highest Shannon index, whereas sand habitats exhibited the lowest values for abundance, richness, and diversity. Organism abundance peaked in the mid tide zone, with summer and autumn showing the highest abundance, richness, and Shannon index values. Using species accumulation curves with twice the sample size, we predicted richness and Shannon index across habitats, tidal zones, and seasons. Predictions largely aligned with quadrat-scale findings, except that the sand habitat's predicted richness and diversity exceeded those of the algal reef habitat.
