Were the fishing studies re-checked? Yes, one by one
Done: 79 pages are verified and released; 7 studies are now inconclusive.
Research data integrity review: record
From 2026-09-22, we found that some historical catch environment values may not have been aligned with the actual capture time. A value may happen to be correct, but it is not treated as verified without source, time and water-body evidence, so every catch-derived study was withheld.
Each study was then recalculated on a single read-only point-in-time snapshot and checked line by line by an independent program before it returned, with the verification date and scope stated on the page. 79 pages have been verified and released one by one.
Where the data cannot support a conclusion, the earlier conclusion is withdrawn and marked inconclusive, and the page states what was measured and what is missing; 7 of the hypothesis-testing studies are in this group. See Research Methodology: How the Angling-App Catch Studies Work, Their Data Boundaries and Where They Stand Now for the approach and where each study stands.
The data methodology page and the verified-catch cleaning report still show the 2026-09-04 version and stay out of search until they are refreshed.
