What fish are in the By Brook main river?

River evidence passport
Four signals, kept deliberately separate.
The passport shows identity, survey breadth, evidence freshness and trip constraints without turning unlike facts into an opaque “best river” score.
9 sites · 18 events
17 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
