What fish are in the Main Valency?

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.
4 sites · 28 events
7 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
