    Description: This is the fourth River Dart Scale Reading Investigation Report on the 1965 season by the Devon River Board. The object of this investigation is to examine, by means of scale-reading, the general biology of the salmon population of the River Dart. It reviews the methods used for the collection of scales and examination of the materials. It shows the results of the survey and the number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All it summarized in tables, and figures are included plotting weight distributions for each age classes and frequency distributions.

    Description: This is the third River Dart Scale Reading Investigation Report on the 1964 season by the Devon River Board. The object of this investigation is to examine, by means of scale-reading, the general biology of the salmon population of the River Dart. It reviews the methods used for the collection of scales and examination of the materials. It shows the results of the survey and the number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All are summarized in tables, and figures are also included plotting weight distributions for each age classes and frequency distributions. After three years of the investigation a pattern is emerging which shows that the Dart salmon population is mainly composed of four year old fish, which have spent two years in the river and then two year or little longer at sea.

    Description: This is the first River Dart Fisheries Survey produced by the Devon River Authority; which was carried out from May to October 1965. The objective was to examine the distribution and relative abundance of salmonid fish in the River Dart, in order to assess the possibility or desirability, of increasing salmon smolt production of the river by artificial propagation or other means.Description, chemical, pollution and biological conditions of the River Dart along with fisheries catches, water extraction and spawning are briefly cited. The method includes the choice of sections and sampling techniques. The results go through the number/type/class of fishes counted while the survey took place, distribution patterns within the different transects/brooks, competition between salmon parr and trout and estimations of population. The section on the discussion and recommendations is introduced by a brief explanation of the bases for the Artificial Propagation Programme and the River Dart specific case-study. The annexes contains River Dart and tributaries maps, fish size distribution tables and figures, tables with totals of salmonid fish found and population density tables.

    Description: This is the second River Dart Fisheries Survey produced by the Devon River Authority; which was carried out from April to July, 1969. The objective was to examine the distribution and relative abundance of salmonid fish in the River Dart, in order to assess the possibility or desirability, of increasing salmon smolt production of the river by artificial propagation or other means.In addition to the tributaries examined in the 1965 survey, further sections were studied on the River Hems and Holy Brook and reference should be made to the River Survey Report, 1965 for introductory information. The method includes the choice of sections and sampling techniques. The results go through the number/type/class of fishes counted while the survey took place and distribution patterns within the different transects/brooks. The discussion tries to remark the importance of understanding the differences between 1965 and 1969 surveys. The Appendix contains tables with totals of salmonid fish found and distribution sizes for each section, population density tables and a map with new surveyed sections.

    Description: This is the River Dart Fisheries Survey 1974 report produced by the South West Water Authority. The survey was carried out between July and October 1974 to assess the extent of the 0+ and 1+ Salmo salar L. population in the Dart catchment and thereby assess directly the success of the 1973/74 and 1972/73 spawning season. The survey showed that there were large numbers of salmon parr distributed throughout the upper reaches of the Dart, reflecting the successful spawning of the 1973/74 and 1972/73 season. It contains tables with survey sections locations, presence/absence for each section and location maps with spawning grounds and sampling stations.

    Description: 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.
