River Lemon (Teign catchment) fisheries survey

This is the River Lemon (Teign catchment) fisheries survey report produced by South West Water Authority in 1979. This report aims to determine the penetration of Salmon into the River Lemon System and to a lesser degree estimate the population of resident salmonids. Five sections were surveyed being easily accessible and fishable by electro fishing methods.

River Avon (including Glazebrook) fisheries survey 1978

This is the River Avon (including Glazebrook) fisheries survey 1978 report produced by South West Water Authority in 1978. This report aims to determine the penetration of Salmon into the River Avon system and to a lesser degree estimate the population of resident salmonids and other indigenous species. Six sections were electro fished at accessible points as detailed below. All fish were identified and measured. Each section was fished through three times to take the majority of the resident species. Small specimens of salmonid fry, eels and lamprey were common in almost all River Avon sections with the exception of Shipley bridge and Avon Dam but due to the mesh size of the standard dip nets used, many slipped through making accurate number estimation impossible.

Fisheries survey of the River Taw 1977

This is the Fisheries survey of the River Taw 1977 report produced by South West Water Authority in 1978. The upper reaches of the River Taw were severely polluted in October 1975 and there was widespread fish mortality. A survey was carried out to assess the recovery of salmonid stocks in the affected areas. Salmon showed a rapid recovery and trout have also recovered well. Both species have been assisted by widespread stocking. Several other species were present. Salmonid and total fish biomass was high. Further stocking of salmon is not recommended and it is also suggested that stocking with trout should be discontinued.
