This is the River Plym Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Plym Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Plym SAP follows the format of those completed for the rivers Tamar, Lynher, Tavy, Camel and Fowey. It is the sixth of seven action plans that will be produced for salmon rivers managed by Cornwall Area. The River Plym SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably, there are historic workings for china clay and a significant potable water supply at Burrator Reservoir. The main River Plym has been designated as River Ecosystem class 1 for its water quality objectives. This is the highest water quality target set for rivers. This standard has been met in all reaches of the main River Plym and River Meavy.

This is the River Plym Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Plym catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. These issues and actions follow on from the detailed analysis of the catchment, which is presented in the River Plym SAP Consultation document.The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the River Plym SAP therefore, is to maintain, improve and develop the River Plym salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. The River Plym has failed to pass its conservation limit since 1996, and the consultees felt very strongly that there were three major factors limiting the salmon stock of the River Plym.

This is the River Axe Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Axe Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. This document is part of a national initiative to produce action plans for the management of all the main salmon rivers of England and Wales by 2003. The aim of this plan is (i) to assess the status of the salmon stocks and fisheries of the River Axe - including the use of Conservation Limits as part of this process, (ii) to identify factors which may be limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The salmon stock of the River Axe was apparently in a healthy state in the 1950s, supporting net and rod fisheries with average annual catches of around 100 and 50 fish respectively. Catches declined through the 1970s and 1980s to the extent where no salmon were recorded in the late 1980s and early 1990s. This decline was probably due largely to the effects of agricultural pollution, which virtually extinguished the salmon stock of the River Axe. Water quality has subsequently improved, but has deteriorated again in recent years.

This is the River Axe Salmon Action Plan Final document produced by the Environment Agency in 2004. The River Axe Salmon Action Plan (SAP) has been produced after consideration of feedback from public consultation. The final plan provides a list of the agreed issues and actions for the next five years to maintain and improve the salmon stock of the River Axe. Efforts have been made to identify possible sources of funding, partners and timescales. It indicates how the plan will be managed, including the process for reviewing stock status, issues, actions and progress. Low marine survival is currently a major factor limiting salmon stocks throughout the United Kingdom. However, on the River Axe the freshwater environment is still the main factor limiting the recovery of the salmon stock. Most of the adults returning to the Axe at present are probably derived from hatchery reared smolts, although there has been some natural reproduction in recent years. Juvenile populations in the Yarty indicate that this is a tributary where salmon have started to re-establish a self-sustaining population. Actions to improve the quality of the freshwater environment, both in terms of water quality and sedimentation, are seen as the top priorities, and are required to allow the Axe to support a self-sustaining salmon population.

This is the River Dart Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Dart Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The north of the River Dart catchment is included in the Dartmoor candidate Special Area of Conservation (cSAC), designated under the Council EC Directive 92/43/EEC, the “Habitats Directive”. One of the conservation objectives for the cSAC is to maintain the habitat for Atlantic Salmon, Salmo Salar in favourable condition. The River Dart is an important salmon, sea trout and brown trout fishery with no significant coarse fishery. However, eels are ubiquitous throughout the catchment and are lightly exploited. The River Dart SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery.

This is the River Dart Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Dart catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Dart salmon stock. The low marine survival (likely to be below 10%) is possibly to be the main cause for the River Dart salmon stock non-compliance with its conservation limit. Actions protecting smolts and maximising spawning activity of returning adults are seen as priorities to contribute to mitigate the low marine survival. Also the lack of information on salmon stock and its habitat is recognised as one main factor limiting the better management of salmon fisheries. Efforts will be focused on gaining more knowledge and improving modelling techniques. The actions presented in this document are perceived as those required to address the important issues and factors limiting the salmon stock. This SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the River Dart salmon stock and fisheries.

This is the River Exe Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Exe Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Exe SAP follows the format of those completed for the Rivers Teign, Torridge, Taw and Dart. It is the fifth of eight action plans that will be produced for salmon rivers within Devon Area. The River Exe SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Exe salmon stock is judged to be meeting its Conservation Limit. However, this assessment is uncertain as it is based on an estimate of rod exploitation rate, which in itself is also uncertain. At present there is no means of accurately assessing the River Exe salmon run. In common with many other rivers, estimation of stock using catch statistics and rod exploitation rate is the model used, when direct assessment is not possible. The installation of a fish counter on the lower river, or the use of other direct counting methods, would help to provide a direct assessment of the annual run of salmon into the river. This would improve our ability to estimate the spawning escapement and hence assess compliance with the Conservation Limit.

This SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the River Exe salmon stock and fisheries. The River Exe salmon population is currently judged to be passing its Conservation Limit. However, its apparent declining trend in egg deposition in the recent years and the high uncertainty in its stock assessment suggest the following actions as priorities: actions promoting good land management, maximising salmon natural spawning activity and protecting smolts throughout the Exe catchment. Also, the lack of information on salmon stocks and its habitat quality and availability is recognised as the main factor limiting the better management of salmon fisheries. The actions presented in this document are perceived as those required to address the important issues and factors limiting the salmon stock.
