Fisheries Survey River Avon, 1962

This is the Fisheries Survey River Avon, 1962 by the Devon River Board. The object of the survey is to investigate the present distribution and relative abundance of salmonid fish in the river. It describes the methods of the investigation, the sampling and identification. It goes through the salmon, sea-trout and brown trout parrs, adult and coarse fish frequencies and distributions, all summarized in individual tables for each fish class. It also includes a variety of comments about the obtained results.

River Teign Fisheries Survey 1963

This is the River Teign Fisheries Survey from 1963 by the Devon River Authority. The principal object of the survey is to examine the distribution and relative abundance of salmonid fish in the river system in order to assess the possibility of increasing the salmon population by artificial propagation. A secondary object is to examine the condition of the river downstream of the Rookery Brook confluence, which was affected by the pollution and fish mortality in 1962 to assess the advisability of restocking the length with brown trout. The report contains a brief introduction of the general aspects of the catchment, chemistry, pollution, biology and fisheries in the river, methodology that looks at the selected transects and techniques for sampling and results. In the appendix, it is explained why the Board have decided to proceed with the artificial propagation and the required procedure. Maps with survey sections and fish indices along with tables with size distributions and totals of salmonids found are attached.

River Teign Fisheries Survey 1979

This is the River Teign Fisheries Survey from August 1979 by the South West Water Authority. The River Teign was sampled by electrofishing at fifteen sites and population estimates, average lengths, weights and biomass were calculated for each species present, and where possible for individual age classes of those species. Results indicated that a stable community structure existed, and little had changed from 1963. Salmonids accounted for the majority of the biomass, and within this group trout were the most abundant in the headwater, and salmon in the lower reaches. All tributaries sampled had higher densities and biomass than the main river. The results were compared with other data collected from similar surveys of other rivers in Devon by the South West Water Authority. Both the average length of each age class, and the biomass in the main River Teign appeared to be lower than in most other rivers, although in the Rivers Wray and Lemon these values were particularly high.

River Exe Fisheries Survey 1966-1967

This is the River Exe Fisheries Survey 1966-1967 by the Devon River Authority. This is the fifth Fisheries Survey to be carried out in the initial series, other surveys having been carried out on the Rivers Teign, Torridge, Dart and Erme. The object of the survey was to examine the distribution and relative abundance of salmonid fish in the river system, in order to assess the possibility, or desirability, of increasing salmon smolt production of the river by artificial propagation or other means. The survey was carried out from middle May to end of July in 1966 when further survey work was prevented by high water levels, and from the end of June to the end of September in 1967. It contains a brief introduction of general aspects of the catchment, chemistry, pollution, biology and fisheries in the river, methodology that looks at the selected transects and techniques for sampling, results and recommendations. The results goes through totals of all salmonid fish caught, adults, parrs and estimations of parr population individually for salmo salar and salmo trutta. Maps with survey sections and fish indices along with tables with size distributions and totals of salmonids found are attached.

Salmon Scale Reading Investigation 1972

This is the Salmon Scale Reading Investigation from 1972 by Cornwall River Authority. The object of this investigation is to examine, by means of scale reading, the biology of age classes of the salmon populations of the River Tamar, River Tavy, River Lynher, River Fowey, River Camel and River Plym. It contains for each river the numbers of caught salmon, number of scales received and which were unreadable and percentages in each age group separately for net and rod caught. Length and weight frequency distribution histograms have been plotted to show the size distribution of the various sea age group.

Effects of water quality in Bassenthwaite Lake on anglers' catches of salmon and sea-trout in the River Derwent

This is the report on the Effects of Water Quality in the Bassenthwaite Lake on Anglers Catches of Salmon and Sea-trout in the River Derwent April 1993 by the Institute of Freshwater Ecology. An analysis of the catch statistics for salmon and sea-trout in the Rivers Derwent and Cocker was undertaken in relation to available information on the algal water quality in Bassenthwaite Lake to test the hypothesis that poor catch returns were associated with a deterioration of water quality within the lake. Analysis of the catch statistics failed to reveal any correlation between water quality and catch returns for either species of fish and it is concluded that any water deterioration in Bassenthwaite Lake has not caused any major damage to the salmon and sea trout fisheries of the Derwent/Cocker system. This conclusion is supported by the analysis of the Windermere/Leven and Crake system, where no correlation could be found between lake water quality and downstream catches of migratory salmonid fish. However, the possibility still exists and such an effect might be detected by further field work on the macroinvertebrates and on the composition of potential salmonid spawning in the area.

The fisheries Aspects of North West Water AuthoritySchemes to Increase Water Abstraction in West Cumbria

This is the report on the Fisheries Aspects of North West Water Authority Schemes to Increase Water Abstraction in West Cumbria by the Egremont and District Anglers’ Association. Existing river pollution and water abstraction in the Ennerdale Lake-River Ehen system is shown to have caused a major deterioration in the conditions in the Ehen fishery. This is reflected by the fact that catches of salmon, sea trout and smelts on the Ehen have all fallen to roughly 6% of the 1965 level; wich is far worse than the deterioration shown in salmon catches for S. W. Cumberland as a whole. Recommendations are made, in the light of proposals by North West Water Authority to increase water abstraction in West Cumbria, to prevent further deterioration in the Ehen fishery in the short term and to improve the situation in the longer term. It contains sections on pollution, water abstraction and fisheries background, flow statistics for and discussion of high water-droughts on the River Ehen, effects of droughts on Tidal Water and a discussion of N.W.W.A. Paper entitled `Water Resources in West Cumbria’ in the light of conditions on the River Ehen.
