Freshwater Biological Association

We are the voice for freshwaters. The Freshwater Biological Association is dedicated to understanding and protecting freshwater environments across the world. We are advocates for one of the most vulnerable ecosystems on the planet.

We inspire local and global action to protect freshwater ecosystems through science

Understand. Participate. Protect.

Our Association has the knowledge and data to drive positive action. We make a measurable impact on the ground through our science-based projects, species recovery programmes and citizen science activities.

We train and educate freshwater scientists, building a community to protect freshwater habitats.

Our members and Fellows are at the heart of our Association, working collectively to shape the scientific agenda, influence policy and to deliver tangible change.

Join us at the Annual Scientific Meeting on 25 June 2025!

  • Annual Scientific Meeting 2025

    Wednesday 25 June at Nottingham Trent University

    This conference-style event includes unmissable keynotes from Steve Ormerod (Cardiff University), Michelle Jackson (University of Oxford), Dave Tickner (WWF-UK) and Julia Ortega-Martin (University of Leeds). The ASM will additionally showcase the research and practice of other FBA members including staff, early career scientists and fellows.

  • FBA Early Career Member Network

    FBA Early Career Member Network

    Through the FBA Early Career Member Network (ECMN) FBA wish to improve the support we give to early-career researchers and practitioners. Our ambition is that ECMN members benefit from career-related support, and our Fellows and staff are well-placed to provide such support.

  • FBA History

    For over 70 years the Freshwater Biological Association has published scientific books for researchers, professionals and enthusiasts. Publications by leading scientists and practitioners in freshwater biology, limnology and aquatic ecology, edited by the FBA.

  • Volunteers study invertebrates on a lake shore

    Become an FBA Volunteer

    Here at the FBA we have a range of volunteering opportunities for those who are interested in being a part of a team who believe in the conservation and preservation of both freshwater environments and historical science collections.

  • People studying small freshwater creatures in a lab environment

    Training with the FBA

    Discover the fascinating world of freshwater biology! We offer a range of courses with specialist tutors for beginners, enthusiasts and professionals. Learn to identify freshwater life and develop your understanding of sampling and monitoring.

Freshwater is essential for our planet.

The 0.01% of the planet that makes up our lakes, ponds, rivers, streams, wetlands and bogs provide essential ecosystem services such as food and water for billions of people. They are also essential for nature and wildlife.

Our freshwaters host 10 times the biodiversity per area than the land and the sea. They also provide habitat for one third of all vertebrate species.

FBA action for freshwater ecosystems.

Despite their importance, many freshwater ecosystems are highly degraded and in ecological decline. They suffer from the impacts of pollution, invasive species and habitat loss. Without urgent action to better understand, conserve and sustainably manage freshwater ecosystems, this decline will only increase. The climate crisis will also exacerbate the rate of decline.

Find out more about our activities supporting freshwater ecosystems.

The Freshwater Biological Association is dedicated to understanding and conserving freshwaters across the globe. We have been advancing freshwater science and conservation action since 1929, to protect our global fresh waters by delivering and enabling freshwater science, conservation action, advocacy and learning.

Support the FBA.

By becoming a member you will automatically contribute directly to our pearl mussel conservation project, as well as advance the understanding of fresh waters and ensure a healthy future for all of our river and lake habitats. Alternatively you may donate directly to the project. We are extremely grateful for all donations that are received. Thank you.

Get Involved!

We welcome volunteers at FBA and we are happy to discuss how your skills and interests could support our science, training and advocacy work based at our sites in Cumbria.
