Kaluga
Huso dauricus-Critically Endangered
About the Kaluga
The Kaluga can grow up to 2,200 pounds and up to 18.5 feet. The Kaluga was discovered in the 1800's and lives in the entire Amur River basin from the estuary to the river’s upper reaches. They eat pike, carp, herring, chum salmon, and other fish or shellfish that can fit into their mouth. They migrate upriver in spring to spawn.
Population Trends
- 595 tons in 1881
- 61 tons in 1948
- 89 tons in 1996
Ecological Effects
River pollution, destruction of natural habitats, destruction of natural watercourses, and change in spawning routes are all examples of ecological effects of the extinction. One way we can fix this is if we regulate the rules better, and to keep a couple in a controlled environment.
