In November 2024, the NRF-SAIAB team, led by former Managing Director Emeritus Prof. Paul Skelton, Acting Managing Director Prof. Albert Chakona, and Communications and Stakeholder Relations Manager Lucky Dlamini, embarked on a week-long roadshow to launch the latest edition of Freshwater Fishes of Southern Africa: A Complete Guide. This fully revised third edition, authored by Prof. Skelton, is an invaluable resource cataloguing over 300 freshwater fish species, including newly described species, updated taxonomy, high-quality photographs, and distribution maps.
Originally published in 1993, with a second edition released in 2001, Freshwater Fishes of Southern Africa has long been regarded as an essential reference for understanding the biodiversity of the region’s freshwater ecosystems. The 2024 edition brings updated insights and expanded content that reflect decades of research and fieldwork.
A Journey Across South Africa’s Inland Provinces
The book launch tour covered key inland provinces – North West, Limpopo, and Mpumalanga – engaging academic institutions and stakeholders to strengthen freshwater research collaborations. The roadshow initially began on 17 October 2024 at the Two Oceans Aquarium in Cape Town, hosted by Struik Nature Club, the book’s publisher. A second launch was held at the Harald Porter Gardens in Bettys Bay on the 19th December. Then a third, key launch took place at NRF-SAIAB’s headquarters in Makhanda as part of the annual Smith Memorial Lecture, where Prof. Skelton paid tribute to the legacy of J.L.B. and Margaret Mary Smith, pioneers in South African ichthyology. This was particularly significant, as Prof. Skelton played a key role in preserving the Smiths’ legacy and steering NRF-SAIAB as its Director from 1995 to 2011.
Beyond promoting the book, the roadshow to the northern provinces served as a platform to introduce the potential establishment of a Joint Freshwater Research Laboratories Programme, an initiative spearheaded by Prof. Chakona, NRF-SAIAB’s Chief Scientist. This programme seeks to establish collaborative freshwater research laboratories at inland universities, mirroring the success of the DSTI/NRF-SAIAB Joint Marine Laboratories Programme launched between 2022 and 2024 with coastal universities.
Strengthening Research Collaborations
North-West University (NWU): Bridging Ichthyology and Parasitology
NRF-SAIAB’s first inland stop was at North-West University (NWU), where the delegation was hosted by the Water Research Group (WRG). The event, held on 4 November at the NWU Sports Village, brought together academics, researchers, and conservationists. NWU and NRF-SAIAB share a longstanding research collaboration, and this visit reinforced ties, particularly in fish parasite studies. Discussions uncovered synergies for future joint projects, including integrating cutting-edge infrastructure housed at NWU’s Zoology Department.
The event also served as a moment of reflection for many who have been inspired by Skelton’s work. NRF-SAIAB Honorary Research Associate and contributor to the book’s section on parasites, Prof. Nico Smit, shared how Freshwater Fishes of Southern Africa influenced his academic journey. “I remember reading The Skelton as a student,” Prof. Smit said, referring to the book by its affectionate nickname. “It was the reason I fell in love with ichthyology. Paul’s dedication to his work is truly inspiring.”
Additionally, the visit aligned with global health priorities, as NWU researchers study waterborne diseases such as bilharzia (schistosomiasis), a parasitic infection linked to contaminated freshwater. This collaboration has the potential to support Sustainable Development Goal (SDG) 3: Good Health and Well-being by addressing neglected tropical diseases.
University of Limpopo (UL): Fostering Young Researchers
The roadshow continued at the University of Limpopo (UL), where NRF-SAIAB was hosted by Prof. Wilmien Luus-Powell, DSI-NRF SARChI Chair in Ecosystem Health. The enthusiasm of young MSc and PhD candidates highlighted the impact of the visit, as Prof. Skelton’s words of wisdom inspired the next generation of aquatic scientists. Discussions centered on enhancing researcher access to national facilities like NRF-SAIAB, ensuring students can leverage world-class technology and expertise.
The team initiated discussions with Prof. Ngonidzashe Moyo and Dr. Evelyn Raphalo, who heads the Aquaculture Research Unit at UL, to explore options for collaboration to expand aquaculture research in southern Africa. This is critical, as sustainable aquaculture development has the potential to address the challenges of food and nutrition insecurity, particularly for rural poor communities. By promoting sustainable aquaculture, NRF-SAIAB and UL aim to contribute to SDG 1 (No Poverty), SDG 2 (Zero Hunger), and SDG 3 (Good Health and Well-being).
During the visit, University of Limpopo Vice-Chancellor and Principal, Prof. Mahlo Mokgalong, made a special appearance, exchanging warm greetings with his longtime colleague, Prof. Skelton – an acknowledgment of their shared passion for freshwater research.
University of Mpumalanga (UMP): Expanding Research Initiatives
On 7 November, the roadshow made a stop at the University of Mpumalanga (UMP), where key stakeholders from UMP and NRF-SAIAB held a joint research meeting. The meeting, led by Prof. Aldo Stroebel, Deputy Vice-Chancellor for Research, Innovation, and Internationalisation at UMP, and Dr. Tatenda Dalu, Senior Lecturer and Group Leader of the Aquatic Systems Research Group at UMP, focused on the proposed NRF-SAIAB-UMP Joint Freshwater Laboratory. The discussion centered on exchanging ideas, enhancing joint research support, and celebrating the release of an important new publication. This stakeholder meeting was followed by the launch of Prof. Skelton’s book, which brought together experts, scholars, and enthusiasts.
During his presentation, Prof. Skelton reflected on the importance of sustainable practices and urged greater awareness around environmental conservation. “The degradation of our rivers and water systems due to pollution and the spread of invasive species such as bass, tilapia and trout into sensitive habitats is a serious concern. We must foster a culture that respects and conserves these natural resources, not only for the health of the ecosystem but for our dignity and survival,” he said.
Prof. Skelton concluded by encouraging young scientists to contribute their talents and help build upon Africa’s rich biodiversity knowledge. “Through collaboration, illustrations, and infographics, we hope to inspire future conservationists and researchers to take the lead in this vital work. The book also extends beyond scientific documentation; it is a call to action for the next generation.”
Representing NRF-SAIAB, Prof. Albert Chakona spoke warmly about UMP’s rapid development and the significance of the partnership. “We are grateful to join hands with UMP, a young institution on a remarkable growth trajectory. Today’s event is not just a book launch but a celebration of the shared vision of our two institutions,” he said.
Chakona encouraged students to take advantage of NRF-SAIAB’s cutting-edge resources, including tools for molecular analysis and deep-sea exploration.
Loskop Dam: Celebrating Freshwater Biodiversity
The roadshow concluded with a visit to the Loskop Dam Nature Reserve in Mpumalanga, renowned for its diverse fish populations, including tilapia (kurper) and largescale yellowfish. Loskop Dam provided the ideal setting for engaging with the angling and boating community. Prof. Skelton shared valuable insights on conservation and sustainable fishing, emphasising the role of both scientists and the public in protecting freshwater ecosystems.
One of the most impactful additions to the new edition is the chapter on Human Interest Towards Freshwater Fishes. Skelton highlighted the vital relationship between communities and freshwater species, stating, “In many parts of southern Africa, such as rural Angola, Mozambique, Zimbabwe and Zambia, fishing is not just a pastime – it’s a lifeline. For some, it’s their only means of securing food. This book aims to emphasise the human connection to these species and the pressing concerns surrounding overfishing and habitat destruction.”
“This new edition is the culmination of years of research and experience,” said Skelton during his speech at the launch. “The process has been incredibly rewarding, but it also underscores the ongoing need for science to engage with local communities and address the challenges they face. It’s not just about fish; it’s about people and the ecosystems they rely on.”
The book launch events across all the venues concluded with a book signing session, where Prof. Skelton engaged with attendees, answered questions, and inspired the next generation of conservationists.
Looking Ahead: Future Book Launches and Collaborations
The success of the 2024 roadshow has laid the groundwork for further engagements in 2025, with planned book launches at the University of Venda, Sol Plaatje University, and the University of Zululand. These ongoing collaborations will continue fostering partnerships that expand research capabilities and conservation efforts for South Africa’s freshwater biodiversity.
Freshwater Fishes of Southern Africa: A Complete Guide remains an essential resource for anglers, students, academics, and conservationists, offering unparalleled knowledge on Southern Africa’s aquatic life. Through continued collaboration, NRF-SAIAB aims to drive impactful research, support national development strategies, and contribute to the sustainable management of natural resources.
