Restormel Fish Counter Annual Report 2006

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.

Restormel Fish Counter Annual Report 2007

This is the Restormel Fish Counter, Annual Report 2007 produced by the Environment Agency South West Region on March 2008. 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 2007 to February 2008 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). The minimum upstream salmon estimate for 2007, over the period July 2007 to February 2008, was 796, which is the fifth highest recorded count over the past 13 years. The number of returning salmon in 2007 suggests a downward trend in numbers since 2004. The 2007 large sea trout count is similar to 2006. Overall, the number of fish returning is still low in comparison with the 10-year average. There was a noticeable decrease in the number of small sea trout returning compared to 2006 and the 10-year average. The Fish counter at Restormel suffered several faults.

The minimum upstream salmon estimate for 2008, over the period July 2008 to February 2009, was 938 and is the third highest recorded count over the past 14 years. The 2008 large sea trout count (482) shows a marked improvement in the number of returning fish when compared to 2007 (241). There was a significant decrease in the number of small sea trout returning in 2008 when compared to 2007 and the 10-year average.

Restormel Fish Counter Annual Report 2010

This is the Restormel Fish Counter, Annual Report 2010 produced by the Environment Agency South West Region on June 2011. 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 2010 to February 2011 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws. The minimum upstream salmon estimate for 2010, over the period July 2010 to February 2010, was 1220. The fish counter at Restormel suffered from only one major period of unscheduled downtime during 2010/2011. This was due to a counter fault over the period 21 to 30 August 2010 and equated to 10 days of downtime.

Restormel Fish Counter Annual Report 2011

This is the Restormel Fish Counter, Annual Report 2011 produced by the Environment Agency, Environmental Monitoring Team on May 2012. 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 2011 to February 2012 inclusive. The minimum upstream salmon estimate for 2011, over the period July 2011 to February 2012, was 675. The minimum upstream sea trout estimate for 2011 was 10,022, which is the fifth highest count recorded in the last 17 years. The fish counter at Restormel had six periods of downtime due to counter faults which equated to 19 days of downtime overall. Fish counts were estimated for downtime caused by counter faults but not for weir cleaning due to the small numbers of fish involved.

The effect of water quality on coarse fish productivity and movement in the Lower River Irwell and Upper Manchester Ship Canal a watercourse recovering from historical pollution

This is the Effect of water quality on coarse fish productivity and movement in the Lower River Irwell and Upper Manchester Ship Canal: a watercourse recovering from historical pollution report produced by the Environment Agency in 2003. The aim of this study was to investigate the impact of water quality upon coarse fish population dynamics in a lowland, urban watercourse. All of the research carried was undertaken in the lower River Irwell and upper Manchester Ship Canal, between February 1998 and December 2001. Of particular interest was the natural sustainability of the urban fishery given recent concern raised in the angling community over an apparent decline in coarse fish populations in lowland rivers. The research described in this report has concentrated upon the role of water quality in determining coarse fish population dynamics, and in particular: The impact of water quality upon fish growth and productivity; The impact of poor water quality and low dissolved oxygen concentrations upon fish distribution and movement; The impact of water quality upon the sexual development of fish.

Episodic variations in stream water chemistry associated with acid rainfall and run-off and the effect on aquatic ecosystem, with particular reference to fish populations in N.W. England

This is the episodic variations in stream water chemistry associated with acid rainfall and run-off and the effect on aquatic ecosystems, with particular reference to fish populations in North West England produced by the North West Water Authority in 1985. This report looks at the biological, physical and chemical information collected over a five year period from over 100 sites on upland streams in the North West Region of which drained rocks of low buffering capacity. In both Lake District and South Pennine sites striking differences were found between the composition of invertebrate communities inhabiting acid-stressed and less acid-stressed streams. Electric fishing surveys showed that acidic streams (geometric mean pH <5.5) generally had abnormally low densities of salmonids ( < 0 .2m2) and that 0+ fish were very few or absent. The latter indicates recruitment failure. Salmon were more sensitive than trout to low pH.

A comparative survey of the fish populations of 10 West-Midlands meres of SSSI status

This is a comparative survey of the Fish Populations of 10 West-Midlands Mere of Site of Special Scientific Interest Status. The meres of the Shropshire-Cheshire plain (West Midlands) comprise over 60 water bodies. Water quality in the meres ranges from naturally eutrophic to nutrient limited and some of them have received Site of Special Scientific Interest status (SSSIs). This survey was commissioned in order to obtain quantitative information on the fish fauna of selected SSSIs and evaluate the likely impact of fish on other species within the community. The current survey was concerned with 10 of the West Midlands’ meres, a cross section of sites was selected. Sites were widely distributed from Marton Pool in the south-western part of Shropshire to Tabley moat in Chesire. Meres varied in size, depth and nutrient status. All were to be sampled using the methods outlined. The report is divided into different sections for clarity and ease of reference. The materials and methods section provides an outline of the location and status of each mere and information on known fish species present. The results were considered individually and comparatively, relative abundance of fish, species present, their diet, sex, age, parasite burdens and growth. Inter-site comparisons were made using information derived from echo-soundings, growth rate, diet, and species abundance for each site. The final section will be in the form of a general discussion, comparative information from longer term studies, conclusions and recommendations.
