Abstract:
The NRA presented Swansea City Council (SCC) with study proposals for assessing the impact of the Tawe barrage on the migration of salmon and sea trout in the estuary, based on the use of fish telemetry. These were rejected by SCC largely on the basis of cost and reservations as to the practicability of the studies. The NRA therefore commenced water quality and fisheries studies, whilst these negotiations were in progress. Fisheries studies in 1990 and 1991 have been reported. These demonstrated that firstly sufficient numbers of salmon and sea trout suitable for tagging could be caught using a bag net in Swansea bay and by relocation from Panteg fish trap, secondly tagged fish could be tracked through the Tawe estuary and past the barrage site, using existing telemetry technology. An agreement has been reached between the NRA and SCC to jointly fund a scaled down telemetry study, considered by the NRA to be the absolute minimum level of investigation commensurate with the objectives of the study. Welsh Office (WO) have given their assurance that they will accept this study together with trap data as means of evaluating performance with respect to formal fish pass approval. The study was carried out over 2 years, the extension of the study into a second year was dependent on the results of year one. The study started in 1993 as the first complete year following impoundment.
