Kanas Lake giant fish
In 1985 Xinjiang University biologist Yuan Guoying and his students reported more than fifty enormous fish, estimated at 10–15 m, in Kanas (Hanas) Lake.

The account
Tuvan and Kazakh locals had told of lake beasts for centuries; tourist videos since the 2000s keep the 'Kanas monster' alive.
The sceptical view
Chinese scholars on CCTV suggested giant taimen (Hucho taimen); the size estimates are almost certainly exaggerated.
The researched reading
A biologist saw large fish from a distance and overestimated them. Big taimen explain the sighting; 10–15 m fish are biologically implausible in this lake.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 50% | Kanas Lake holds taimen (Hucho taimen), the largest salmonid, which can exceed 2 m. Viewed from a mountain at distance, a group of large fish near the surface, with their wakes, is easily overestimated many times over. |
| A cultural story | 14% | Tuvan and Kazakh legends of lake beasts, and later tourism promotion of the "Kanas monster", keep the story alive. |
| Undetermined | 12% | The share a generic explanation had beyond what has been shown for this case: it fits many cases like this one, but has not been demonstrated for this one. |
| Perception, memory or mind | 9% | Size judgement over water without reference points is notoriously poor. |
| A hoax or fabrication | 8% | Later tourist videos include unreliable material, but the 1985 report was sincere. |
| An unknown or out-of-place animal | 6% | Fish of 10–15 m would need a food web the cold, low-productivity lake cannot supply; a record-sized taimen is far more likely. |
| Genuinely anomalous | 1% | Nothing requires more than large fish. |
Official position: No official finding; Chinese scientists suggested giant taimen.
