The Japanese sturgeon or Amur sturgeon (Acipenser schrenckii) is a
critically endangered.[1]
Habitat and ecology
The Japanese sturgeon is
benthic. Their main food sources are aquatic insect larvae, bony fish and mollusks. One study suggests that the type of aquatic insect larvae eaten by juvenile Japanese sturgeon depends on the season, where mayfly nymphs are eaten more frequently in spring and fall, and midge larvae are eaten more frequently in summer.[7] The females mature at 9–10 years of age, and males at 7–8 years. They start to migrate in the autumn. They live for 65 years.[6]
