Contemporary genetic structure of Atlantic salmon ( Salmo salar L.) in the River Moy in Ireland is shown here to be strongly related to landscape features and population demographics, with populations being defined largely by their degree of physical isolation and their size. Samples of juvenile salmon were collected from the 17 major spawning areas on the river Moy and from one spawning area in each of five smaller nearby riv...
Spatial and temporal patterns in microsatellite DNA variation of wild Atlantic salmon, Salmo salar , in Irish riversNARA Subscribed
Two sequential year classes of Atlantic salmon parr, Salmo salar L., from 13 rivers throughout Ireland, genotyped at four widely used microsatellite loci, displayed comparable levels of intra‐sample genetic variability to elsewhere in the species range. Temporal allele frequency differences were observed in only one riverine sample, whereas significant spatial differences were evident in all cases, with an overall F ST value o...
Temporal and environmental influences on the variation in Atlantic salmon smolt migration in the Burrishoole system 1970–2000NARA Subscribed
The relationships between a number of environmental variables and the number of Atlantic salmon Salmo salar smolts migrating in the Burrishoole system, western Ireland, were examined over a 30 year period from 1970 to 2000. The number of Atlantic salmon smolts recorded migrating downstream decreased significantly from an annual mean of 11 579 in the 1970s to a mean of 6272 in the 1990s. The primary factor in the decline in Atl...
The Irish sea trout enhancement programme: a review of the broodstock and ova production programmesNARA Subscribed
The Irish sea trout, Salmo trutta L., broodstock programme was instigated in response to the collapse of sea trout stocks in the west coast of Ireland in 1989 and 1990. Wild sea trout kelts and post‐smolts were successfully reconditioned and used as broodstock to produce eyed ova for distribution to affected fisheries. From 1991 to 1999, a total of 8.2 million green ova from four separate stocks were produced. The number of fe...
The Irish sea trout enhancement programme: an assessment of the parr stocking programme into the Burrishoole catchmentNARA Subscribed
The success of the sea trout, Salmo trutta L., enhancement programme carried out in the Burrishoole catchment in the west of Ireland from 1993 until 1998 is reviewed in terms of the number of fish stocked, the number of fish which migrated to sea and the number which returned from sea during this period. The success of the programme is also evaluated in terms of the cost of producing parr for stocking and the subsequent value...
