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 20 years ago
Coverage runs from 7 Jul 1988 to 12 Oct 2006. This is historic monitoring, never a live presence or catch forecast.
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.
