SHOCK IN THE LABORATORY They opened 40-year-old cans and found an AMAZING THING instead of spoiled fish
Ordinary, forgotten, canned salmon from warehouses, over 40 years old, turned out to be a real scientific treasure, Newsweek reports.
TL;DR
- Over 40-year-old canned salmon from warehouses revealed scientific value.
- Researchers from the University of Washington analyzed salmon canned between 1979 and 2021.
- The presence of parasitic nematodes in the salmon, though considered harmless after canning, indicated a robust marine ecosystem.
- The lifecycle of these nematodes requires multiple hosts, and their abundance suggests these hosts were successfully found and reproduced.
- This suggests a stable or recovering ecosystem, with sufficient appropriate hosts available.
- The presence of these parasites can be linked to the availability of small marine invertebrates, smaller fish, and marine mammals.
- Old canned fish can act as a 'time machine' to study changes in the ocean.
- Increased ocean temperatures or positive effects of clean water acts could explain observed changes.
