How long does a Shortnose Sturgeon live?
The shortnose sturgeon (Acipenser brevirostrum) is known for its long life, where the males can survive for 30 years, while the females can live up to 67-70 years of age.
How do they reproduce?
The shortnose sturgeons have an interesting reproduction, and the water quality of a river matters to the fishes. The females spawn every three years, while the males spawn every year. After hatching, the early life stages are spent in freshwater, and the fry later moves on to more brackish environments. The females can lay about 40,000-200,000 eggs which made the fish a delicacy to many people. It takes 13 days for the eggs to hatch in the river, and as it is sticky, the eggs usually stick to other surfaces like rocks present in the river. It takes 9-12 more days for the fry to mature and swim towards deeper river channels.
