Observations on a bloom of Flagellate "X" in the West of Ireland
Dunne, T.
In July 1983 major mortalities of farmed trout and salmon were associated with a bloom of an unidentified organism hitherto unrecorded in Ireland. Three further blooms occurred in 1984, two of which were associated with mortalities. The morphology of this organism (Flagellate "X") as observed in 1983 is described.

Observed sequential occurrence of phytoplankton and zooplankton in the Dunkellin Estuary, Galway Bay, Ireland
Byrne, P.; O'Mahony, J.H.T.
The Dunkellin is a small tidally-dominated estuary to the south-east of Galway Bay in western Ireland. The plankton of the estuary was studied for 18 months between December 1984 and July 1986. This paper presents results on the variation in the sequential occurrenCe of phytoplankton and zooplankton between the inner and outer estuary. Phytoplankton and microzooplankton occurred in high numbers in the spring to autumn months. Highest abundances of phytoplankton and microzooplankton (non-tintinnid ciliates and tintinnid ciliates) were recorded 10 the Inner estuary, whereas mesozooplankton were predominant in the outer reaches.

Toxic phytoplankton in Irish waters
Silke, J.; McMahon, T.; Nolan, A.
The subject of harmful and toxic marine algae has recently gained a growing public and scientific interest both in Ireland and abroad because of the occurrence of these toxins in shellfish.

Report on the incidence and implications of phytoplankton blooms on the East Coast and particularly Wexford Harbour, Summer 1984
Doyle, J.; Dunne, T.
The Fisheries Research Centre had a number of reports of discoloured water between Brittas Bay Co. Wicklow and Wexford Harbour and south to Kilmore Quay. Samples of water received from Dr. David Jeffrey, Department of Botany TCD, collected from Penny-come-quick beach, co. Wicklow on June 17th and examined by Tom Dunne in the Laboratory contained dense colonies of Phaeocystis pouchetii - a microscopic algae. Subsequent samples collected by Miss Ann Kiley, Wexford County Council, traced the extent of the bloom as far south as Neamstown near Kilmore Quay. A sample taken at Cullenstown west of Kilmore Quay was clear. Also associated with this bloom were large numbers of needlelike diatoms (Nitzschia spp. More seriously, blooms of another microscopic alga (Prorocentrum minimum) began to develop in early July during the later phase of the Phaeocystis bloom.
