I am off on a short break to Torquay at the start of April and I was wondering if anyone can recommend a fishery nearby?

Try here: Newhouse Trout Fishery, Morleigh, Totnes, Devon TQ9 7JS

A nice fishery in a lovely setting in a valley on a tributary of the River Dart, It can get weedy in high summer but the deep water at the dam end is usually clear.

Or Kennick if you fancy something a bit larger:
