Relationship between freshwater angling catch of Atlantic salmon and stock size in the River Bush, Northern Ireland
Autor: G. J. A. Kennedy, W. W. Crozier
Publikováno v: Journal of Fish Biology. 58:240-247
Over 25 years rod catches of Atlantic salmon Salmo salar increased proportionately as stock size increased (r 2 =0.581, P 0.5). On a 15 year sub-set of these data annual effort (P=0.804) and flow (P=0.339) had little significance relative to stock si

Relationships between marine growth and marine survival of one sea winter Atlantic salmon, Salmo salar L., from the River Bush, Northern Ireland
Autor: G. J. A. Kennedy, W. W. Crozier
Publikováno v: Fisheries Management and Ecology. 6:89-96
An examination of marine growth/marine survival relationships in Atlantic salmon, Salmo salar L., was carried out, based on scale growth measurements in relation to two indices of marine survival in wild fish from the River Bush, Northern Ireland. Th

Application of a fry (0+;) abundance index, based on semi-quantitative electrofishing, to predict Atlantic salmon smolt runs in the River Bush, Northern Ireland
Autor: G. J. A. Kennedy, W. W. Crozier
Publikováno v: Journal of Fish Biology. 47:107-114
An abundance index for 0+ Atlantic salmon was based on semi-quantitative electrofishing estimates at 137 sites in typical juvenile habitat throughout the River Bush (N. Ireland). 0 + abundance was linearly related to total smolt numbers migrating thr

Application of semi-quantitative electrofishing to juvenile salmonid stock surveys
Autor: G. J. A. Kennedy, W. W. Crozier
Publikováno v: Journal of Fish Biology. 45:159-164
A semi-quantitative electrofishing technique is described, which has applications for assessing distribution and densities of 0+ salmonids in streams. Linear regressions of logarithmically-transformed data satisfactorily described the relationship be

Evaluation of Carlin tagging as a mark-recapture technique for estimating total river runs of salmon smolts, Salmo salar L
Autor: C. D. Strange, P. M. Johnston, G. J. A. Kennedy
Publikováno v: Aquaculture Research. 22:363-368
Mark-recapture experiments using Carlin tags on migrating wild smolts in the River Bush indicated that 16·4% were not recovered under total trapping conditions. The experimental procedure was also found to delay the migration of the smolts by varyin

The fish of Lough Neagh
Autor: G. J. A. Kennedy, K. U. Vickers
Publikováno v: Monographiae Biologicae ISBN: 9789048142361
The fisheries of the Lough Neagh catchment have been the subject of a number of historical reviews (Donnelly, 1986; Mitchel, 1965; Thompson, 1856, see also Chapter 6) and recent species lists have been compiled by Kennedy (1978) and Wilson (1979). Mu

Impacts of agriculture on aquatic systems: lessons learnt and new unknowns in Northern Ireland
Autor: W. C. K. O' Connor, S. I. Heaney, G. J. A. Kennedy, W. W. Crozier, R. H. Foy
Publikováno v: Marine and Freshwater Research. 52:151
Agriculture in Northern Ireland depends on grass-based production, but since 1980, expansion of output has been effectively constrained by production limits set by the European Union agricultural policy. Despite this, long-term monitoring over severa
