Western Atlantic: Hamilton River, Labrador, Newfoundland, Canada to northeastern Florida, USA. Occurs occasionally in Bermuda and French Guiana (Ref. 7251). Northern Gulf of Mexico (Ref. 26938). In Europe: Baltic Sea. Landlocked populations in Lakes Ladoga and Onega (Russia), both now extirpated. Occasionally recorded from Great Britain and North Sea in Elbe drainage (Ref. 59043). Recent research revealed that this species existed in the Baltic Sea, but is now extirpated (Ref. 83384, 83385). Near threatened globally, but extirpated in Europe (Ref. 59043).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Anadromous species. Occurs solitarily or in small groups; inhabits shallow waters of continental shelves. At the sea, it occurs in coastal and estuarine areas on soft bottom (Ref. 59043) down to a depth of 50 m (Ref. 89115). Adults are highly migratory while at sea (Ref. 57533) and make long migrations along the coast (Ref. 59043). Feeds on benthhic invertebrates such as mollusks, crustaceans and aquitic insects from the sediments (Ref. 93252). They forage mainly in brackish waters (Ref. 59043). Ascend large rivers to spawn (Ref. 59043). Juveniles may remain in fresh or brackish water until 2-5 years of age or 76-91.5 cm long (Ref. 4639, 59043). Today most individuals do not exceed 250 cm length. Tagging studies have shown that this species may move distances up to 1,450 km (Ref. 89119). Used smoked and fresh (Ref. 37032). Near threatened globally, but extirpated in Europe due to massive overfishing, damming, river regulation and pollution (Ref. 59043).

Matures at increasing ages with increasing latitude (Ref. 88171). Both sexes do not spawn yearly and spawning intervals may vary according to area. In the St. Lawrence River, males spawn every 1-5 years, females every 3-5 years (Ref. 89103). Adults from the sea begin to ascend the lower reaches of large rivers in spring with the majority ascending immediately prior to spawning. Spawning occurs between March and August (Ref. 59043), when water temperature is 13.3-17.8 °C (Ref. 89118). Spawning occurs over bedrock, boulders or gravel bottoms, in depths exceeding 10 m at current velocities of 0.5-0.8 m/s (Ref. 59043, 89103). Exact time of spawning depends on temperature (Ref. 26938). Per female 0.4-8 million eggs may be spawned (Ref. 45706, 84845, 89137). Eggs demersal, sticking to stones, measuring 2.55 mm in diameter and hatching in 1 week at 17.8 °C (Ref. 4639, 9980). Adults return to the sea after spawning (Ref. 59043). Sturgeons in general have a high capacity for hybridization and most species are able to cross-breed (Ref. 89103, 89117).
