indistinguishable on the basis of the morphology of the rostrum. E. occultus can, however,

be easily recognised by the possession of a seven-jointed carpus on the second pair of

pereiopods as opposed to a six-jointed carpus in T. cranchii and by having a two-segmented mandibular palp.

In Irish waters, as elsewhere, the two species have undoubtedly been confused and to

date E. occultus has been recorded as such only once from the Irish coast. This record is of

one specimen taken from sublittoral weeds in Lough Ine, Co Cork (Holmes 1980). In recent

years E. occultus has been frequently taken, particularly off the west coast. Localities

include Rutland Island, Burtonport, Co Donegal among Laminaria holdfasts at 5m depth, 10.4.1981; Killary Harbour on Serpula vermicularis reefs, June 1974; Kilkieran Bay and

adjoining bays, Co Galway, at all seasons, where the species is widespread on a variety of substrates, Zostera beds, oyster beds, on maerl beds among Flustra, Antedon and Sabella,

and where it is especially abundant together with T. cranchii among algae growing on oyster and scallop spat collectors; Valentia Island, Co Kerry, off Beginish Point on scallop spat collectors, October 1975; Bantry Bay, Co Cork off Dunboy Castle, 4.11.1977; Kinsale Harbour, south of Preghane Point, August 1978, 18m on rock; Kilmore Quay, Co Wexford, at low water on the rocky shore between the pier and Forlorn Point and on the rocky shore 0.5km north of Carnsore Point, Co Wexford at low water.

Geographically the species ranges from Bergen southwards on the Norwegian coast and is recorded from the Gullmarfjord and the Koster area of Sweden (Greve 1963); it occurs on south, southwest and west coasts of Britain as far north as the Clyde sea area

(Smaldon 1979) and the Isle of Man (Bruce, Colman and Jones 1963). The species is found at Roscoff, Finisterre (Bourdon 1965); the Golfe de Gascogne (Lagardere 1969); Atlantic and Mediterranean coasts of Spain (Zariquiey Alvarez 1968) and Marseille (Bourdillon-Casanova 1960). There is a single doubtful record from the coast of Morocco

(Lagardere 1971).

REPORT OF MEETING

SEMINAR ON ADVANCES IN FISH BIOLOGY IN IRELAND, 23-24 APRIL 1981

The Seminar was organised by the National Committee for Biology of the Royal Irish Academy.

Delegates were welcomed by Professor P. MacCana, President of the Academy, and the opening address was given by Mr P. Power, Minister for Fisheries and Forestry. The Seminar was dedicated to

the memory of the late Dr A. E. J. Went whose sudden death prevented him from taking a major part in

the organisation work and sadly deprived the meeting of a valued contributor to the discussions.

The principal aim of the Seminar was to bring together research workers involved in all aspects of

the biology of fm fish in Ireland and to publish their papers in a report which should give an indication

of the status of the whole field offish and fisheries biology in 1981. Accordingly, papers were invited

from workers in the three areas of Ecology, Population Studies and Aquaculture and Health. In

addition to the invited papers, offers of other contributions were requested. Six papers in each of the

three areas were accepted. Publication is expected before the end of 1982.

In the Ecology section two papers were given on cyprinids, one on juvenile salmonids, one on the

impact of arterial drainage, one on gobiesocids and one on the parasites of salmon. Three of the six

papers on Population Studies were concerned with salmonid stock assessment in freshwater and two

on salmonid genetics. The sixth gave a survey of pelagic fish stock assessment which has been in

progress for 20 years. Under the heading of Aquaculture and Health was one paper on the

development of rainbow trout farming in Ireland since its inception in 1967. Two papers covered

diseases of farmed salmonids; furunculosis and kidney disease and one gave a review of long

established studies on Lymphoma in pike. Studies on the blood of fish were approached from two

angles: one on the development of haemoglobin patterns in salmon and grilse, the second on the

leucocytes of pike. The collected papers will provide a valuable digest of the present state of research work.

Salmonid biology and aquaculture are very well represented and the only major study which is not

included is that of demersal fish stocks.

In its aim of organising a gathering of fishery scientists the Seminar was highly successful. 38

research workers attended, representing 6 Government or Government-sponsored fishery institutes

and 5 College or University Departments. There were also 18 students and the total attendance of 56

represented the majority of fishery workers in the country.

FIELD RECORDS ? PLANTS

Plant records are compiled by P. Hackney, Ulster Museum, Belfast 9, from reports of

BSBI County Recorders. Any records received by P. Hackney or the Editor will be passed to the Recorder concerned. Plant names are in accordance with Scannell and Synnott's

Census Catalogue of the Flora of Ireland except in special cases.

FURTHER PLANT RECORDS FOR CO WATERFORD (VC H6) supplied by I. K. Ferguson and L. F. Ferguson, c/o Royal Botanic Gardens, Kew, Richmond, Surrey, TW9 3AB.

These records are based primarily on collections and field observations made by I.K.F., who is

BSBI County Recorder, and his wife during August 1978. There are a small number of earlier records

and records kindly supplied by Miss M. J. P. Scannell, Dr A. O'Sullivan and Lady Anne Brewis. The

records extend the lists published inlNJ 16 (4): 94-97 (1968) and 18 (3): 85-87 (1974). IKF & LFF followed by a four figure number, refer to specimens collected by the authors which are deposited in

the Herbarium at the National Botanic Gardens, Glasnevin, Dublin (DBN). The existence of voucher

specimens collected by other recorders is signified by citation of the collector and date of collection
