Tas fishing evidence · East Anglia
What fish are in the Tas?
Monitoring has recorded 25 species across 11 surveyed sites on this water, between 1987 and 2026. 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.
11 sites · 90 events
25 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
