Title: River Leach fisheries survey 1993
Author: R. Preston
Document Type: Monograph
Abstract:
This survey of the River Leach follows on from the survey carried out in 1987 and is part of the five year rolling programme of surveys undertaken by Thames Region NRA. Six sites on the River Leach were surveyed by electric fishing between 08-06-93 and 22-07-93. Of the six sites surveyed two are designated salmonid fisheries under EC fisheries directive 78/659/EEC, and both exceeded their biomass targets of 15g/m2. Lack of suitable spawning sites appears to be largely responsible for the poor natural recruitment of the brown trout population. The drought period from 1989 to 1992 caused much of the "ephemeral" Leach above Eastleach Martin to be dry for longer periods than normal, and this may have had some effect upon recruitment.
