Separate-signal passport

What this record proves — and what it does not.

No blended quality score. Identity, monitoring, freshness, access and rules stay as separate signals so one strong fact cannot hide a missing one.

Latest survey about 1 year ago

Coverage runs from 23 Sept 1993 to 19 Jul 2025. This is historic monitoring, never a live presence or catch forecast.

04 · Trip constraints

Access remains unresolved

The survey carries no fishing-rights boundary, permission, opening status or safety notice. Check the owner, rod licence, current byelaws and conditions separately.

Location protection: AnglerRadar does not print the survey coordinate on this page, and nearby API results use coarsened survey areas rather than exact species-linked points.
