Title: Great Brook fisheries survey
Author: E. Hopkins
Document Type: Monograph
During the period 26.6.92 to the 16.7.92 a total of four sites were surveyed by electric fishing. The Great Brook is designated under E.C. fisheries directive 78/659/EEC as a cyprinid fishery. Two of the sites failed to achieve their biomass targets of 20g/m2. The two remaining sites easily exceeded this target. The Great Brook is a man made channel, extensively modified in the past for flood defence purposes, with a detrimental effect on habitat especially along the lower reaches. The water quality on the Great Brook showed a compliance with River Quality Objectives (RQO) in all cases, with biological monitoring results supporting these findings.
