River Dart Scale Reading Investigation Report on the 1963 Season
This is the second River Dart Scale Reading Investigation Report on the 1963 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 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 alo included plotting weight distributions for each age classes and frequency distributions. The report also remarks the similarity of the results with those for 1962.
