The largest sturgeon on record was a beluga female captured in the Volga Delta in 1827, measuring 7.2 m (23 ft 7 in) long and weighing 1,571 kg (3,463 lb). Most sturgeons are anadromous bottom-feeders , migrating upstream to spawn but spending most of their lives feeding in river deltas and estuaries .
The lake sturgeon uses its elongated, spade-like snout to stir up the substrate and sediments on the beds of rivers and lakes to feed. Four sensory organs hang near its mouth to help the sturgeon locate bottom-dwelling prey. Lake sturgeons can grow to a large size for freshwater fish, topping 7.25 ft (2.2 m) long and 240 lb (108 kg). [8]
Siberian sturgeon usually weigh about 65 kg, with considerable variability between and within river basins. The maximum recorded weight was 210 kg. As with all other acipenserids, the Siberian sturgeon are long-lived (up to 60 years), and late to reach sexual maturity (males at 11–24 years, females at 20–28 years).

Atlantic sturgeon under six years of age stay in the brackish water where they were born before moving into the ocean. They may be 3–5 ft (0.91–1.52 m) long at this stage. In areas where shortnose sturgeon are also present, the adults of that species can be, and historically were for centuries, confused with immature Atlantic sturgeon. When ...
A season was set, and harvest limits: Anglers could take home two sturgeon a year, and the fish needed to be between 38 and 63 inches long. People loved it. Anglers flocked to the lake, catching ...
Pallid sturgeon have a long lifespan, living in excess of 50 and perhaps as long as 100 years. [19] [20] [21] They lack bones and scales, which makes it more difficult to establish their age and determine exactly how long they live. [22] As is true for many long-lived species, pallid sturgeon reach reproductive maturity relatively late. [23]
