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.
