This is the Restormel Fish Counter, Annual Report 2003 produced by the Environment Agency South West Region on March 2004. The report presents the daily upstream counts of migratory salmonids recorded on the River Fowey at Restormel weir fish counting station (SX 107 613) in 2003. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Bylaws. The run pattern observed for salmon and sea trout in 2003 was generally consistent with that of previous years. The upstream salmon / large sea trout count for 2003 was 1777, 2% lower than that recorded in 2002. The overall increase in the salmon and sea trout counts, together with the consistency of the numbers over recent years suggests that measures designed to protect salmonid stocks were working.

This is the Restormel Fish Counter, Annual Report 2006 produced by the Environment Agency South West Region on March 2007. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel weir fish counting station (SX 107 613) over the period March 2006 to February 2007 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (2 March- 15 June inclusive). The minimum upstream salmon estimate for 2005 (1046), over the period July 2005 to February 2006, was 20% lower than that recorded over the same period in 2004 (1301). However, this is the second highest count recorded over the past 11 years. The total sea trout count (10448) was 8% higher than 2004 (9608). The number of salmon and large sea trout was lower than average in 2005. However, the overall numbers of adult salmon and sea trout returning have been increasing year on year since 1997. This overall increase in the salmon and sea trout counts, together with the consistency of the numbers of fish returning over recent years suggests that measures designed to protect salmonid stocks in the River Fowey are working.

This is the Salmonid & Freshwater Fisheries Statistics for England & Wales 1996 produced by the Environment Agency in 1997. The principal aim of the Environment Agency in respect of fisheries is to maintain improve and develop fish stocks, the basic fisheries resource, in order to optimise the social and economic benefits from their sustainable exploitation. This report is the second collation of salmon and migratory trout catch statistics for England and Wales produced by the Environment Agency. For the years 1989-94, these statistics were published by the National Rivers Authority (NRA) and the years 1983-88 by the Ministry of Agriculture, Fisheries and Food, Directorate of Fisheries Research in its Data Report series. The 1996 data, have been presented in a broadly similar format to those of 1995. This report makes a general review of different catches: Northumbria, Yorkshire, Anglian, Thames, Southern, Wessex, South West, Severn-Trent, Welsh and North West.

This is the report on the Effect of Abstraction on Fish and Fisheries presented at the 24th IFM Annual Study Course, The Changing Face of Fisheries September 1993 at Cardiff. Water is abstracted from rivers for a wide variety of uses and causing potential for conflicts between abstracters, fisheries and conservation interests, especially during natural low flows. It looks at the potential effects that flow reduction has over various stages of salmonids at various stages of their life history. The flow at the time of smolt migration has been found to be positively correlated with the number of returning adults, and flow is considered to be one of the most important environmental factors inducing salmonids to enter fresh water and ascend rivers. The importance of time series data on fish stocks and angling success together with models which ultimately relate discharge to standing stock are discussed in relation to the setting up of Minimum Acceptable Flows.

This is the River Fowey Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Fowey 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 Fowey salmon stock. 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 Fowey SAP therefore, is to maintain, improve and develop the Fowey salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. Although the Fowey is passing its conservation limit, the consultees felt very strongly that there were two major factors limiting the salmon stock of the River Fowey- the overgrazing of Bodmin Moor and the use of the catchment for water supply by South West Water.

This is the Rivers Avon & Erme Salmon Action Plan Consultation document produced by the Environment Agency in 2003. 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 rivers Avon and Erme - including the use of Conservation Limits as part of this process, (ii) to identify factors which may limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The report pays attention on the external consultation of the Rivers Avon & Erme Salmon Action Plan (SAP). While the stocks of both rivers have exceeded their respective conservation limits occasionally in individual years, only the Erme has achieved a period of statistical compliance since 1993. It is possible that this situation is largely normal, due to the steep nature of the rivers, obstructions to migration and dependence on suitable flow conditions occurring at the right time of year. The decline of the spring-running component of the stocks has left the populations dependent on autumn flows for the success of the late running component. Actions required to improve compliance with Conservation Limits are proposed and prioritised. The urgent actions relate to the need to improve the consistency with which adequate numbers of salmon reach and utilise fully all the accessible areas of the river systems. This document is intended to be dynamic, with opportunities for review occurring at regular intervals. For example, as the science of fisheries management improves, particularly in the setting of Conservation Limits, so the targets may be altered to reflect any improved methodology.

This is the Rivers Avon & Erme Salmon Action Plan Final document produced by the Environment Agency in 2004. The Rivers Avon and Erme 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 stocks and fisheries of both rivers. 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 the numbers of salmon returning to spawn in both the Avon and the Erme. Actions to improve the accessibility of spawning areas and to maximise the productivity of spawning and nursery habitats are seen as priorities, which should help to offset the low marine survival. The quality of the information available to assess salmon stocks is recognised as a limiting factor in the management of salmon fisheries. The SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the salmon stocks and fisheries of the Avon and the Erme.

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 Exe Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Exe catchment has been produced after consideration of feedback from external consultation. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. 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.

This is the River Taw Salmon Action Plan Consultation document produced by the Environment Agency in 2000. The report pays attention on the external consultation of the River Taw Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Taw Salmon Action Plan (SAP) includes a description of the current status of the rod and net fisheries and historical trends. The Taw salmon stock has declined since the 1960s and is currently failing to meet the spawning target. The decline in the spring fish component has accounted largely for the overall decrease in stocks. The reasons for the decline are unclear, but the spring fish problem is recognised as a national issue. The rate of survival over the marine phase has reduced in recent years for both the grilse and MSW components. This is undoubtedly a contributory factor, which may now constrain stocks to lower levels than have existed historically.

This is the River Teign Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Teign Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Teign Salmon Action Plan follows the format of those completed for the Rivers Torridge, Taw and Dart. It is the fourth of eight action plans that will be produced for salmon rivers within the Devon Area Fisheries, Recreation and Biodiversity Team. The River Teign SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Teign salmon stock is currently failing to meet its conservation limit. This failure is largely attributed to the reduction in the survival rate during the marine phase of the salmon life cycle. This is likely to constrain stocks to lower levels than have existed historically. Still further catch controls may contribute to a reduction in exploitation rates and allow stocks to recover to meet their conservation limit. Other important actions include the continuation of habitat improvement works which aim to maximise spawning habitat utilisation, spawning success, and juvenile survival and production.
