Event description

Since the 1970s, the population of European Eel (Anguilla anguilla) has declined rapidly by an estimated 90%. Other than over-fishing, the causes for this decline are thought to be primarily due to human infrastructure constructed in rivers and estuaries that either create a barrier to migration, such as dams and weirs, or present a life-threatening hazard such as hydro-turbines and power station cooling water intakes.

One way to better understand the relative impacts of human infrastructure on the eel migration and population is to build a numerical model. A form of numerical model that is suited to modelling fish movement and behaviour is an agent-based model (ABM).

This presentation describes the basic concept of an ABM for modelling fish behaviour and how it has been developed to simulate the up-estuary migration of juvenile eels as they navigate from the ocean to rivers. The potential for the model to be used for assessing impacts on eel migration is demonstrated through the application of the model to two estuaries in the UK.

Open to members and non-members, relevant to anyone with an interest in environmental modelling and aquatic systems.

Part of the CIWEM Biodiversity digital series.

About the speakers

Dr Thomas Benson

Dr Thomas Benson is a Principle Researcher in HR Wallingford’s Coasts and Oceans Group. After leaving school he embraced the world of academia, gaining a degree in Ocean Science, a Masters degree in Advanced Instrumentation Systems and a PhD in modelling sediment dynamics in estuaries. For the past 15 years he has been applying his knowledge at HR Wallingford, working on many marine related research and consultancy projects. During this time he has continued learning and expanded his expertise into the fields of underwater noise propagation modelling and agent-based modelling of fish behaviour.
