Description:
An electrofishing survey was undertaken in the period April 24th - 28th as part of the detailed biological study of the Calder Catchment being carried out by this department in early 1978. The sites to be fished were selected to indicate broadly the fishing status of the major sections of the main river and its larger tributaries and by no meansintended to describe the fishing status of the whole catchment in detail. The results on the distributions of fish species are discussed, in general, in relationto the major polluting influences on the catchment. The results of the second survey are given and discussed separately in Appendix I.
