What fish are in the Stort Navigation (Hertfordshire and North London)?

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.
6 sites · 6 events
12 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
