The River Ehen salmonid fishery - current status and a summary of fisheries work 1993-1996

This is the report on the River Ehen salmonid fishery - current status and a summary of fisheries work during the period 1993-1996, produced by the Environment Agency North West in 1997. This report draws together a number of investigations and surveys undertaken following the 1993 Strategic fisheries survey of the River Ehen. It specifically details the historic catch data available for this catchment for both salmon and sea trout and examines the current stock levels based on this data. Concerns over sea trout stock levels are raised and a detailed examination of the possible limiting factors involved is included. Information from surveys on the River Keekle is analysed with reference to its potential for sea trout production both currently and with the proposed clean up on Oatlands tip. Salmon production in the historically acidified River Liza sub catchment is examined along with ways of boosting production further following recent reductions in acidic episodes. Future and current issues and actions required in the catchment are listed along with the responsible party and estimated costs involved.
