Fisheries Scientist

Wild fish stocks and marine resources

What this life looks like

You protect the fish stocks that millions depend on for food and income. Fisheries Scientists study wild fish populations and marine and freshwater ecosystems to understand fish biology, population dynamics, and the impacts of fishing pressure and environmental change. Africa's fisheries — from Lake Victoria to the Gulf of Guinea to the Indian Ocean — are under enormous pressure, and the science needed to manage them sustainably is urgent.

What she actually does

You conduct fish population surveys, analyse catch data and stock assessment models, study fish ecology and reproductive biology, assess the environmental impacts of fishing practices, advise governments on sustainable catch limits and fishing regulations, investigate the effects of climate change and pollution on fish stocks, and develop management plans that balance food security with long-term fishery sustainability.

Why it matters in Africa

Over 200 million Africans depend on fish as their primary source of protein, and tens of millions earn their livelihoods from fishing. Lake Victoria — Africa's largest lake — has seen major fishery collapses. Coastal fisheries in West and East Africa are significantly overfished. Climate change is shifting fish distributions and affecting ocean chemistry. Fisheries scientists who can provide the evidence for sustainable management are critical to Africa's food security.

Your pathway in

  • Study Marine Biology, Fisheries Science, Zoology, or Environmental Science
  • Develop strong quantitative skills — stock assessment modelling requires statistics, mathematics, and computing
  • Gain field experience on research vessels and at landing sites — fisheries science involves significant time in the field
  • Connect with the African Fisheries and Aquaculture Network and national fisheries research institutes
  • Consider postgraduate specialisation in Fish Stock Assessment, Fisheries Management, or Marine Ecology

Skills you will need

  • Fish population biology
  • Stock assessment modelling (R, FishBase)
  • Field survey and sampling methods
  • Fisheries management frameworks
  • Scientific writing
  • Stakeholder engagement with fishing communities

A woman in this field

Dr. Jacqueline Uku

Kenya

Jacqueline is a premier Kenyan marine scientist and Senior Research Officer at the Kenya Marine and Fisheries Research Institute (KMFRI). She serves as the President of the Western Indian Ocean Marine Science Association (WIOMSA). Her highly influential work focuses on seagrass ecosystems, coastal fisheries management, and empowering artisanal fishing communities to balance marine conservation with economic survival.

Take your first step

  • Research Lake Victoria — Africa's most important and most threatened freshwater fishery — and study what happened to the Nile perch, native cichlids, and the fishery management challenges the lake now faces
  • Explore FishBase at fishbase.org — it is the world's most comprehensive database of fish biology and is an essential tool for fisheries scientists
  • Visit a fish landing site, fish market, or lake or coastal area near you and observe the fishing practices, species caught, and market dynamics
  • Research the Western Indian Ocean Marine Science Association (WIOMSA) at wiomsa.org — they support African marine scientists and run fellowship and training programmes
