Abstract/Summary

Following previous projects which had established that the status of the rare schelly (Coregonus lavaretus) in Haweswater of the English Lake District in north-west England was poor, the present project was commissioned to monitor the status of this population from April 2006 to March 2007 by examining entrapment records and specimens and by hydroacoustics, to undertake a series of cormorant (Phalacrocorax carbo) observations and roost counts over the same period, and to assess cormorant management undertaken at the lake in 2006. During the project, a secondary objective was added to assess the consequences of reducing future such hydroacoustics monitoring to a single annual visit and to make recommendations for its seasonal timing. A further initial objective to develop modelling of schelly population dynamics was not addressed because resources were fully used by the above higher priority objectives.
