Offshore and near-shore energy projects pose potential risks due to electromagnetic fields, habitat competition from both native and non-native species is a high risk, and poor water quality and potential disease transmission from native and non-native species pose a significant future threat.
Sturgeon are an anadromous species that live solitarily or in small groups. They migrate upriver in the spring to spawn. Sturgeons tend to inhabit the shallow waters of coastal shelves, coastal and estuarine areas on soft bottom in the sea, and can live down to a depth of 160 ft (49 m).
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.
