The ESB Sea Bass Tagging Project is an exciting collaborative research project taking place in cork Harbour over the next two years.

Listening station or receiver, inset (A) is a transmitter

The project’s main objective is to tag 60 sea bass with acoustic transmitters so that researchers can acoustically track their movements through the harbour.


Once attached, each transmitter emits a ping that is detected by nearby receivers, listening posts, located on the sea bed. The study is funded by ESB and Science Foundation Ireland. It is led by the Coastal and Marine Research Centre of University College Cork in close collaboration with Inland Fisheries Ireland and the local angling community.

Why Carry out such a project?

Sea bass are an iconic species amongst anglers and very important to local tourism, generating economic benefits for Harbour communities. Sea bass were almost wiped out in Irish waters until they became Ireland’s only protected fish species in 1990.

Since then sea bass have been regarded solely as an angling species and are strictly managed. This project is the first of its kind in Europe and will help us better understand and conserve this important fish species by investigating their movements and migrations.

How you can help

If you catch a tagged fish, please release it back into the harbour and report the capture to the CMRC. Tagged fish will carry a floy tag imprinted with contact details.

All of our receivers will be moored as shown with a red surface bouy and and orange sub-surface float approximately 3m off the sea bed. The surface bouy is marked UCC experimental equipment. In the event of accidental entanglement or collision with one of the bouys/receivers please contact Dr Tom Doyle of the Coastal & Marine Research Centre.
