• Second report on the fishes of the Irish Atlantic Slope

      Holt, E. W. L.; Byrne, L. W. (His Majesty's Stationary Office, Dublin, 1909)
      Many of the fishes which inhabit the deeper water of the Atlantic coast are unfamiliar to fishermen, and were not described in the books to which the general reader had ready access in the early 1900s. It was therefore the intention of the authors to give an account and figure; or sketch, of all except the well-known kinds. This is the second report in an occasional series on the fishes of the Irish Atlantic Slope.
    • The Fry of Salmon and Trout

      Anon. (Department of Agriculture, 1938)
      Every year large numbers of salmon fry (parr and smolts) are destroyed, sometimes quite unwittingly, by anglers who are unable to distinguish between salmon fry and young trout. Under Section 73 of the Fisheries (Ireland) Act, 1842, it is illegal to take the fry of either salmon or trout. The term “trout fry” has not yet received a legal interpretation but in some Fishery Districts the taking of immature trout below a certain size is prohibited by by-law. The fry of salmon are legally deemed to include also those fish locally called "jenkin" and "gravelling."
    • Salmon and Trout: Natural and Artificial Propagation as Factors in the Maintenance of Stocks

      Anon. (Department of Agriculture, 1939)
      The object of fishery regulations whether statutory or departmental is, in the ultimate, conservation. That is to say, it is sought by the imposition of certain restrictions to ensure such a run of fish for breeding purposes as will increase or at least maintain the stocks. Many citizens profess dissatisfaction with the existing stocks of fish in our rivers and lakes and persistently urge that they should be enhanced by all practical means. Generally the method which suggests itself to such persons is the setting up of a hatchery, to be operated either by stripping fish captured locally or by procuring supplies of ova (eggs) from outside sources. There seems to be a rather widespread belief that such a procedure even on a modest scale is bound to produce immediately beneficial results for the waters concerned. In other words, the operation of a hatchery is expected to offset completely the evils of over-fishing, as well as the damage resulting from illegal activities (whether within or outside the fishing season) and the reduction in stocks caused by predatory birds, fish and mammals added to the pollution of waters by the entrance of deleterious matter. Such a belief is, however, fallacious as it cannot be accepted in any degree without serious reservation.
    • Prawn Fishing

      Gibson, F A (Department of Lands, 1956)
      The common prawn (Leander serratus) is widely distributed around the Irish coasts, but obviously varies in abundance from place to place. This prawn should not be mistaken for the Norway Lobster, sometimes called the Dublin Bay Prawn (Nephrops norvegicus) or with the brown shrimp (Crangon vulgaris). Alive, the common prawn is a grey-brown colour and has blue bands on its legs. The Norway lobster is a pink colour, and its body is profusely covered with white tipped spines. The common prawn also has a projection from its head, called a rostrum, which is absent from the shrimp. As the prawn is of economic importance, some notes on simple methods of capture will be of interest to fishermen.
    • Some notes on crab fishing

      Gibson, F A (Department of Agriculture and Fisheries (Fisheries Division), 1957)
      Specific fishing on a commercial scale for the edible crab is practised only to a limited extent in this country and, although fairly substantial quantities of edible crabs are landed annually, these are largely the by-product of creel fishing for lobsters and crawfish. These notes give a short account of certain crab fishing methods and record the results of some experimental fishing undertaken by the Fisheries Division.
    • Escallop fishing around Ireland

      Gibson, F A (Department of Agriculture and Fisheries (Fisheries Division), 1957)
      There are, at present, two main centres of escallop fishing around the Irish coasts, one situated in the inlets forming the north side of Galway Bay, and the other along this south-west coast from Schull, County Cork, to Valentia, County Kerry, the beds exploited in these areas are all inshore, ranging from a short distance to about two miles beyond low water mark and in depths varying from two to twenty fathoms. Extensive beds are uncommon, most of them being small and located between rocky areas where the bottom is suitable. Escallops are generally taken in the months of October to April. Minimum size limits are enforced.
    • Review of the Irish Salmon Industry

      Went, A. E. J. (Department of Agriculture and Fisheries [Fisheries Division], 1965)
      For centuries the salmon has been an important item of commerce in Ireland and in many parts of the country today it is still very important in the general economy of the people, who gain a living directly or indirectly from it. It is important from two points of view. It provides sport for the angler and it supports a commercial fishery. There are three other articles in this issue: II.

    • Stocks of Nephrops norvegicus off the south coast of Ireland

      Gibson, F A (Department of Agriculture and Fisheries (Fisheries Division), 1967)
      Nephrops norvegicus is also known popularly as the Dublin Bay Prawn or Norway Lobster. The stocks of prawns in depths down to 60 fathoms (109m) have been studies since 1956, off the south of Ireland, from Mine Head, Co. Waterford, to the Kenmare River, Co. Kerry. The present paper is concerned with data obtained from the research vessel Cú Feasa, together with other samples collected from commercial fishing boats, during the years 1963 to 1966 inclusive.
    • Irish Investigation on the Lobster (Homarus vulgaris Edw.)

      Gibson, F A (Department of Agriculture and Fisheries (Fisheries Division), 1967)
      Commercially the lobster (Homarua vulgaris Edw.) is the most important shellfish in Ireland. The Irish coast is deeply indented, except on the east, and is well suited for the exploitation of lobsters. Even on the east coast amidst a predominantly sandy shoreline, a number of discreet areas are fished actively.
    • Notes On Some Irish Estuarine And Inshore Fishes (With records of the distribution of shads by Eileen Twomey, M.Sc )

      Bracken, J J; Kennedy, M (Department of Agriculture and Fisheries (Fisheries Division), 1967)
      This paper brings together data collected in various ways by the authors, over a period of years. Some of the material described is a by-product of investigations, the primary results of which have already been published. Other material is supplementary to data previously published.
    • Irish Sprats and Sandeels

      Molloy, J (Department of Agriculture and Fisheries (Fisheries Division), 1967)
      In 1965, Ireland imported approximately 13,235 tons of fishmeal for animal feeding stuffs, valued at £827,506. For some time now cosideration has been given to the fish resources around our coasts and whether it would be possible to provide a constant source of supply of materials to the fishmeal industry and the growing number of mink and trout farms. This paper investigates this issue.
    • The Movement of Salmon (Salmo Salar) Through an Estuary and a Fish-Pass

      Jackson, P. A.; Howie, D. I. D. (Department of the Marine, 1967)
      In this paper we have attempted to analyze in quantitative terms the behaviour of the salmon of the River Erne during the important phase of migration when the fish first enter brackish and fresh water.
    • "Specimen" Brown Trout and Sea Trout From Irish Waters

      Went, A. E. J. (Department of the Marine, 1968)
      The present paper deals with all the material collected up to the end of the 1967 fishing season and relates to brown trout of 10 lb weight and upwards and sea trout of 6 lb and upwards.
    • The Whiting Fishery Off Counties Dublin and Louth On the East Coast of Ireland

      Hillis, J P (Department of Agriculture and Fisheries (Fisheries Division), 1968)
      The whiting Merlangius merlangus (L) has for over 30 years been the leading demersal species by weight in the landings of commercial fisheries on the east coast of Ireland. The present study was commenced in the autumn of 1959, using samples of both the commercial fishery and the research vessel Cú Feasa. The present paper describes the commercial catch from port samples supplemented with research vessel material where extra detail is desirable.
    • The Early Life of Brown Trout (Salmo Trutta L.)

      Kennedy, M.; Fitzmaurice, P. (Department of Agriculture and Fisheries [Fisheries Division], 1968)
      The programme of research included field and laboratory studies of certain aspects of the early life history of the trout that are considered below.
    • A Review of the Dunmore East Herring Fishery (1962-1968)

      Molloy, J (Department of Agriculture and Fisheries (Fisheries Division), 1969)
      The winter herring fishery off the south coast of Ireland, based on what is commonly called the Dunmore stock, has been studied in detail by earlier workers and particularly by Bracken and Burd (1965). In their paper, they reviewed the fishery up to 1963 and arrived at conclusions regarding the economic yield of the fishery. They stated that, “ with the major spawning grounds (where the intense fishery takes place) situated within Irish exclusive fishery limits, there is considerable scope for the control of effort in such a way that, for the first time, a herring stock might be rationally exploited”. Since 1963, certain changes have taken place in respect of the stocks themselves and the fishing to which they are subjected. The purpose of this paper is to bring these changes to light and to compare the state of the fishery during the seasons 1962/63 to 1967/68 with that during the period of Braken’s and Burd’s observations.
    • South Coast (Waterford and Cork) Herring Fishery 1968-1969

      Molloy, J P (Department of Agriculture and Fisheries (Fisheries Division), 1969)
      The 1968/69 herring season proper commenced on November 27, 1968 and terminated on February 17, 1969. Prior to November 27, however, some small quantities of herrings had been taken by boats over a large area extending from Hook Head to the Daunt Rock. Fifty nine Irish boats made catches throughout the season and a total of 70,781 crans of herrings were landed which was an increase of 7,438 crans (11%o)n the figure for the previous season. Landings were made on 60 days out of a possible 70. The season, which began later than usual, was very disappointing before Christmas, due mainly to adverse weather conditions and the absence of shoals in inshore waters, After Christmas, however, landings of herrings increased substantially and fishing during January and February was exceptionally heavy, with the result that the total landings for the 1968/69 season were the greatest on record. As in the 1967/68 season, fishing was restricted after Christmas at times due to marketing problems which caused the closure of the ports on a number of occasions. The overall catch would otherwise have been considerably higher. Almost all landings of herrings were made at Dunmore East and Cobh.
    • Irish Pike Investigations

      Kennedy, M. (Department of Agriculture and Fisheries [Fisheries Division], 1969)
      The spawning of pike was studied in 1965 and 1966 in five large Irish limestone lakes-Loughs Sheelin, Ennell, Mask, Corrib and Arrow. The spawning period was found to be February to April. Spawning took place in shallow, sheltered situations where there was a carpet of dead or living vegetation on the bottom at a depth of 20 to 60 cm. Spawning took place by day, at a water temperature of at least 9-1O C, when lake levels were high or rising. Gill-net catches reached a peak during periods of spawning. Weather conditions in February and March were much milder in 1966 than in 1965, and spawning began about a month earlier than in 1965. The eggs of Irish pike are 2.7 to 3.0 cm in diameter. They are golden to honey coloured, with a great many minute oil-globules distributed through the yolk in numerous tiny clusters. The incubation period in the field is probably 8-14 days, and the newly hatched larva is 8.0-9.0 mm long. For the first 10 days or so, the larvae hang vertically from the vegetation by means of adhesive glands on the head. They then become free-swimming, and soon afterwards begin to feed. At this stage they measure 13.0-13.5 mm. Their first food consists of small cladocera and copepods. Later, they feed on larger cladocera, amphipods, isopods, young stages of aquatic insects, and fish fry.
    • Irish Kelt Tagging Experiments

      Went, A. E. J. (Department of Agriculture and Fisheries [Fisheries Division], 1969)
      Since the beginning of the century large numbers of salmon kelts have been tagged in Irish waters and the results have been given in a series of papers...a considerable number of kelts have been tagged since 1962 at a number of stations in Ireland and they form the basis of this paper.
    • Pelagic Eggs and Young Stages of Fishes Taken on the South Coast of Ireland in 1967

      Kennedy, M; Fitzmaurice, P (Department of Agriculture and Fisheries (Fisheries Division), 1969)
      Emes W. L. Halt was one of the pioneers of research on the spawning and early development of marine fishes, and collections of pelagic eggs and young stages of fishes made by him on the west coast of Ireland were the basis of some major contributions to the then young science of fisheries biology (HoIt 1891, 1893, 1899). Much more recently Fives (1967a) has worked on pelagic young stages of fishes taken in the plankton on the coasts of Galway and Clare. Collections of eggs and young stages of clupeoids have been made on, the south coast of Ireland in winter during the years 1960-1962 (Bud and Bracken, 1965; Bracken and Kennedy, 1967). Hitherto, however, no collections of eggs or young stages of other fishes appear to have been made on the south coast. As part of a programme of research by the Inland Fisheries Trust into the biology of the bass, Dicerntrarchus labrax (L.) in Irish waters, tow-netting for bass eggs was carried out at four centres on the southeast and south coasts of Ireland during the period April to June 1967. Pelagic eggs of a variety of species of fish, including bass, were obtained, as well as larvae, post-larvae and fry. The tow-netting was done close to shore and in estuaries-areas not as a rule sampled as extensively as the offshore waters where the major commercial fishes The results of the tow-nettings help, therefore, to fill in some of the gaps in existing data on the reproduction of fishes on the Irish coast.
