A recent study led by Gyrhaiss Kasembele from our team highlights the severe ecological impacts of anthropogenic pressure on the Lubumbashi River system, where mining activity poses a growing threat to aquatic ecosystem health.
While the Lubumbashi River system supports vital aquaculture, agriculture, and domestic activities, it receives large volumes of untreated effluents enriched with trace metal elements (TMEs). Unlike previous research focused mainly on human health risks, this study provides a multi-layered assessment of how metal contamination directly affects aquatic organisms.
Using inductively coupled plasma (ICP) techniques, the research team detected heavy pollution in water (0.053 mg/L Hg) and sediments (997 mg/kg Cu; 1,584 mg/kg Zn). Biological evaluations revealed clear signs of severe environmental stress in fish, including microscopic gill lesions. Additionally, an extensive survey of fish parasite diversity (including trematodes, nematodes, cestodes, and acanthocephalans) established their potential as sensitive bioindicators of ecological degradation.
This work marks an important step toward bridging chemical monitoring, biological stress analysis, and environmental management in the Democratic Republic of the Congo. By combining metal quantification with histopathological and parasitological markers, the findings provide a critical baseline to support sustainable management and conservation of aquatic resources in the Lubumbashi River basin.

At the 7th International Mangrove Macrobenthos and Management conference (MMM7) in Ishigaki, Japan, team member Armando Cruz-Laufer presented ongoing research on the intersection of mangrove ecology, fisheries, and public health in Senegal’s Saloum Delta.
Representing the team alongside colleagues from the Université libre de Bruxelles (ULB) and the TROPIMUNDO network, the presentation showcased multidisciplinary work exploring how mangrove forests—and the human activities within them—shape disease dynamics and aquatic biodiversity.
The study addresses two central questions within the framework of disease ecology and One Health:
Vector Control: Can healthy mangrove ecosystems help naturally regulate mosquito vector populations and limit the transmission of human malaria?
Aquatic Ecosystem Health: How do regional fishing pressures impact the health of local fish communities, particularly regarding their parasite dynamics and infection levels?
Carried out in collaboration with partners at the Institut de Recherche pour le Développement (IRD), Université Cheikh Anta Diop de Dakar (UCAD), the University of Washington, and more, this work highlights the critical role mangrove conservation plays in supporting both ecological resilience and community health.
By evaluating how ecological functions and fisheries management interact with pathogen regulation, the team aims to inform more holistic strategies for managing mangrove biodiversity in West Africa.

Thanks to the excellent trainers we connected with through the IUCN Red List of Threatened Species, Gabrielle Flinn (https://www.gabrielleflinn.com/) and Baudewijn Odé (https://www.researchgate.net/profile/Baudewijn-Ode), and funding from Hasselt University and the Research Foundation-Flanders (FWO-Vlaanderen), the Parasitology & One Health team organised a fruitful Red List Assessor training workshop. Through both theoretical and practical sessions, participants gained valuable insights into the Red Listing process and were well prepared for conducting assessments. With only a few parasite species currently assessed on the Red List, the workshop also provided an opportunity to discuss and brainstorm the particularities of parasitic lifestyles and how these can be taken into account during parasite assessments. We are grateful to all 24 participants who joined the workshop from our own institute, as well as from Natuurpunt (Belgium), the Royal Belgian Institute of Natural Sciences (Belgium), the Royal Museum for Central Africa (Belgium), Justus-Liebig-Universität Giessen (Germany), Universität Duisburg-Essen (Germany), the Royal Netherlands Institute for Sea Research (Netherlands), and the Norwegian Institute for Nature Research (Norway). Thanks to our dedicated and engaging trainers, several of us have already successfully passed the Global and Regional Assessor exam.

The goals and recent results of the AfroWeMap programme were outlined by Nikol Kmentova at the World Biodiversity Forum held in Switzerland in June. The presentation focused on the integrated perspective of the programme combining parasitological insights with bioindicator-based assessments of ecosystem health focusing on wetlands in Central Africa. By incorporating parasites and their macroinvertebrate hosts into water quality monitoring, AfroWetMaP promotes a more ecologically comprehensive and One Health–aligned strategy for ecosystem and public health management. Central to this effort is the co-production of knowledge with local stakeholders.

Last week, our team was represented at the Joint Meeting of the Belgian Society for Parasitology and Protistology and the Dutch Society for Parasitology. We presented our research on parasite and disease ecology.
Emilie Goossens presented her findings on invasive snails that transmit trematodes to African buffaloes. Her work in collaboration with Ruben Schols (Royal Museum for Central Africa) features the first report of an amphistome species, Calicophoron aff. microbothrium, infecting the invasive snail Pseudosuccinea columella. This may have consequences for the transmission of this trematode to buffaloes and other ruminant hosts of C. aff. microbothrium.
Armando Cruz-Laufer presented our team's research on the need for a joint understanding of human and ecosystem health in mangrove forests. On the one hand, the poster focused on the role of mangroves in malaria transmission based on a pan-African analysis of spatial data. On the other hand, Armando presented his results on our research on the predation of mosquitoes by fishes (vector predation), a potential ecosystem service of mangroves, which may be affected by overfishing, marine conservation, and parasitic infections of fishes.

Today, May 22nd, marks the UN's International Day for Biodiversity. It serves as a reminder that biodiversity conservation and restoration efforts require commitment from communities, organizations, and governments working together, and that major changes start off small.
Our team also does its small part in bringing scientific knowledge to the people: for example, last year Linde Cools participated in the yearly BioBlitz hosted by the RBINS as part of WiseNight. While this biodiversity-centric activity was aimed at children, it was clear that their guardians also learned a thing or two about nature that day. Small efforts like these will make communities more appreciative of nature and the work that is done to protect it.

During a recent research visit to Kenya, Miriam Shigoley, Maarten Vanhove, and Nikol Kmentová returned to reconnect with the communities where earlier fieldwork on fish parasites in Nile tilapia had been conducted. The visit focused on sharing research results, engaging stakeholders and strengthening collaboration with Kenyan research institutions. This stay was supported by the FWO short research stay grant.
A participatory focus group discussion was organised with fish farmers and aquaculture extension officers to discuss challenges affecting tilapia health in aquaculture farms. Using participatory tools such as territory mapping and proportional piling, participants mapped their farming systems, prioritised production challenges, and explored cause–and–effect relationships influencing fish health. Parasite information from earlier surveys was introduced to help identify potential exposure points within the farming system.
This session provided an opportunity for farmers and extension officers to exchange experiences and discuss how scientific research can improve aquaculture practices.
In collaboration with the Ichthyology Section of the National Museums of Kenya (NMK), a workshop was organised to present research activities conducted within the Aquatic Biodiversity Research Team at Hasselt University. The presentation highlighted ongoing work on fish parasitology, parasite conservation, and biodiversity initiatives such as FishBase, which NMK also contributes to.
Following the workshop, a practical demonstration was conducted on isolating and identifying fish parasites under the microscope, using both fresh fish samples and museum specimens. This provided an opportunity to exchange methodological expertise and discuss the role of parasite research in aquatic biodiversity studies.

The visit allowed exploratory collaboration with colleagues from both the Ichthyology and Invertebrates sections of the National Museums of Kenya. Aquatic macroinvertebrates were sampled in aquaculture ponds previously screened for fish parasites. This exploratory work aims to investigate how parasite data can be integrated with broader ecosystem indicators, such as macroinvertebrate diversity.
These activities connect with the objectives of the AfroWetMaP project, coordinated by Nikol Kmentová and Maarten Vanhove, which investigates the biodiversity of African wetlands and the role of macroinvertebrates and their parasites as indicators of ecosystem health.
We met with Dr. Johnstone Neondo at JKUAT, Juja campus. He is currently a visiting scientist at the Data Science Institute, Hasselt University, where his work focuses on advancing innovative solutions in biotechnology.
This meeting provided an opportunity to discuss ongoing research activities and explore potential intersections between biotechnology, aquatic biodiversity research, and data-driven approaches to studying biological systems.
At the embassy, we presented our research activities and explained the objectives of our visit to Kenya. The discussion provided an opportunity to highlight ongoing research projects conducted within Hasselt University and, more broadly, collaborations between Belgian research institutions and Kenyan partners. This exchange helped illustrate how field-based research in Kenya contributes to international scientific collaboration.

How can we study the impact of human activity on parasite communities in tropical ecosystem? At the 2025 Annual Meeting of the British Ecological Society in Edinburgh, Armando Cruz-Laufer presented our team's research on the effects of overfishing and marine protected areas on the parasites of fishes in mangrove forests.
We are establishing a first baseline survey of the species diversity and building a first dataset of DNA barcoding data for the parasites occurring in mangrove ecosystems in coastal West Africa (specifically Senegal). The project is a collaboration of our team with the Université Libre de Bruxelles (ULB), the Institut de Recherche pour le Développement (IRD) in Dakar, and University of Washington (UW).
BES is the largest scientific conference dedicated to ecology in Europe and, therefore, provided a excellent platform to present our results and exchange ideas with ecologists from different fields.

Do mangrove fish species feed on mosquitoes that transmit human diseases and does fishing influence the feeding behaviour and health of these fishes?
Our team studies this potential benefit of mangroves through an international collaboration led by Armando Cruz-Laufer together with Oumar Sadio from the Institut de recherche pour le développement (IRD) in Dakar, as well as Maarten Vanhove, Farid Dahdouh-Guebas, and Chelsea Wood. Like in 2022 and 2024, we sampled in the Bamboung Marine Protected Area in the Saloum Delta.
We aim to test whether gut content and parasitic infections of the fish differ inside the protected area, where fishing is not permitted, and outside of it. That way, we will begin to understand how fishing changes the health and diet of fishes in mangrove forests, and how this might indirectly affect human health.

World Archives of Species Perception – Parasite (WASP-P) is a project investigating how people perceive wildlife parasites—ecologically important organisms that are overlooked in conservation.
Within just a few days, the WASP-P online survey received an incredible number of responses from across Belgium, boosted by wide media coverage (including VRT, Het Laatste Nieuws, Het Nieuwsblad, and Het Belang van Limburg).
To make the initiative even more engaging, we added a unique bonus: the public can vote on the scientific names of four newly discovered flatworm species. These parasites had been waiting decades to be formally named, as they were sitting on the gills of riverine cichlids originally collected in the 1940s and 1950s and preserved in the Africa Museum (Tervuren) since then. Voting is open until May 15th.
Here is the link to partecipate: https://tinyurl.com/wasp-parasite
