Several species of sturgeon are harvested for their roe which is processed into caviarâa luxury food and the reason why caviar producing sturgeons are among the most valuable of all wildlife resources. They are particularly vulnerable to overexploitation and other threats, including pollution and habitat fragmentation. Most species of sturgeon are considered to be at risk of extinction, making them more critically endangered than any other group of species.
A combination of factors can be blamed for declines in shortnose sturgeon populations. During the 1800s and early 1900s, large tidal rivers, such as the Hudson, served as dumping grounds for pollutants that lead to major oxygen depletions and resulting high fish losses.nlike most fish species, spawning is not a yearly event for most shortnose sturgeon. Males spawn every other year and females every third year. Females lay between 40,000-200,000 eggs which hatch in approximately 13 days.
