Angling on Lough Derg requires local club membership, available at the local tackle shop in Portumna. There are some good bays around the town, and good bream and rudd fishing in the Shannon and some trout in Lough Derg. Pike is also available, the best months are March to May, and October.
The harbour walls and quays provide good coarse fishing, as does the shore of the lake, with particularly good coarse fishing around Carrigahorig bay.
