Irish Kelt Tagging Experiments
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
The Zoogeography of Some Fishes in Irish Waters
Some thirty years ago the then Fisheries Branch of the Department of Agriculture decided to give rewards for specimens of rare or interesting species of fish sent for examination. This, coupled with the enlightened attitude of Irish fishermen to their catches in recent years, has provided valuable information about the rarer species of fishes found in Irish waters. Even so information is still lacking on many species because normal fishing methods are not really geared to their capture. This is so with many of the smaller members of the fish fauna, and, particularly, those which live in rocky areas where normal fishing is not practised. The advent of skin-diving, however, is likely to improve knowledge of many such species, so that in the near future it may be necessary to revise drastically current views as to the abundance and distribution of many such species of fishes known to frequent Irish waters
"Specimen" Brown Trout and Sea Trout From Irish Waters
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
Review of the Irish Salmon Industry
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.

The Distribution of Irish Char (Salvelinus Alpinus)
Char* (Salvelinus alpinus) are rare in most places in Ireland to-day but they were formerly more widespread
and abundant. About twenty-five years ago the Fisheries Division of the Department of Agriculture and
Fisheries started to offer rewards for char submitted for examination and this has had the result of providing
specimens which would otherwise have been lost. Many of these specimens wcre taken on rod and line but in
recent years considerable numbers have been obtained in connection with either the improvement schemes of the
Inland Fisheries Trust, Inc. or investigations concerned with the effects of drainage operations on Lough Conn

Mariculture in Ireland. Policies and Problems.
Mariculture in Ireland up to 1974 was restricted to the flat oyster (Ostrea edulis) and mussel (Mytilus edulis) but since that year rearing of the Atlantic salmon (Salmo salar) in the sea and of some other species has been undertaken on an experimental basis. Because the fisheries in tidal waters and in the sea are, with some exceptions, vested in the public, legal difficulties can arise in many areas. Some of these legal difficulties in the case of the flat oyster, mussel, cockle (Cardium edule) and periwinkle (Littorina littorea) can be resolved by actions under the Irish Fisheries Acts but with other species new legislation is required for certain forms of activity.
Problems can also arise in connection with the supply of stock for rearing purposes. Stringent regulations are in force regarding the importation of aquatic animals generally with a view to barring those animals which may have an adverse effect on existing stocks of fish or may lead to the introduction of diseases and parasites not already in the country
Sea trout of the River Argideen
A small collection of material consisting of scales and relevant information collected in 1964/5 from sea trout of the Argideen Rive in County Cork was examined and the results compared with those obtained in the years 1954/5
Fluctuations in the Characteristics in Irish Salmon
Fluctuations in the catches and stocks of fish are exceedingly important and have interested scientific workers for years. As far as the salmon is concerned it is known that great fluctuations occur not only in the number of fish entering the rivers from year to year but also in their character. This paper is an attempt to put on record certain changes, some of which have already been recorded in papers on Irish salmon published in a very wide range of journals
