What fish are in the Menalhyl?
Monitoring has recorded 9 species across 12 surveyed sites on this water, between 1986 and 2018. These are survey records with dates. They do not establish what is present today, that the water is fishable, or that you have permission to fish it.
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.
12 sites · 22 events
9 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
