How we study ecosystems
Long-term field research and environmental observations help track change across connected freshwater and marine systems.
Understand marine ecosystems
Explore how ecosystem components interact and how modelling represents connections across space and time.
Ecosystems Overview
Living organisms, water, temperature, nutrients, and seabed-habitat structures exist together and interact within marine ecosystems.
Ecosystem Modelling
Models represent interactions between biological communities and physical and chemical environments across multiple spatial and temporal scales.
Salmon research and fish rearing
Explore experimental datasets, census work, migration research, and freshwater fish-rearing facilities at Burrishoole and Newport.
Salmon Ranching
The Burrishoole programme supports research into Atlantic salmon (Salmo salar) survival, exploitation, and population dynamics in Ireland and the North Atlantic.
Wild Salmon Census
The Burrishoole stock includes one-sea-winter salmon and two-sea-winter or spring salmon, with spring fish normally forming less than 10% of the run.
Salmon Life Cycle
Atlantic salmon hatch in rivers, cross the ocean, and return to their birthplace to spawn.
Fish Rearing
Our Newport facility rears freshwater fish to support research, conservation, and understanding of fish growth and survival.
Long-term catchment monitoring
Explore research on environmental change, fish migration, survival, recruitment, and population dynamics in the Burrishoole system.
Burrishoole Catchment Monitoring Programme
We collect long-term data near Newport to understand how rivers, lakes, fish, and environmental conditions respond to climatic and human activity.
Sea Trout Census
Monitoring tracks sea trout population trends, migration patterns, and survival while supporting research on recruitment and environmental pressures.
Eel Census
The Newport monitoring programme supports research into European eel (Anguilla anguilla) migration, population dynamics, life history, and environmental drivers.
