Like polar bears, the beluga depends on sea ice for … Pallid sturgeon are one of the largest freshwater fish in North America, characterized by their bony plates and pale appearance. Like most other major Sturgeon species, the population of Beluga has declined by over 90% within the last few decades. The Altamaha River supports one of the most robust Atlantic sturgeon populations in the Southeast, The number of juvenile sturgeon produced by these spawning runs ranges from 1,000 to 2,000 individuals occupying the river each year, 87 percent of which are 1 to 2 years of age. For generations, the pallid sturgeon swam freely in rivers from Montana to New Orleans. The beluga sturgeon, or great sturgeon, is the largest freshwater fish in Europe, capable of reaching lengths of 6 meters and weighing over 2000 kg (Exhibit 2, CITES, 2000; In 1994, lake sturgeon were designated as a threatened species in Michigan, marking the beginning of recovery programs to attempt to revive the population. They are an ancient 'dinosaur fish' whose ancestors date back 78 million years. Sturgeon depopulation is occurring in the Caspian Sea - a natural and primary source of the world’s caviar. Population viability analysis (PVA) can be used to partition influences on population recovery, and to distinguish those under the control of the military. Pallid sturgeon are one of the largest freshwater fish in North America, characterized by their bony plates and pale appearance. We used PVA to evaluate threats to recovery of shortnose sturgeon (Acipenser brevirostrum) in a river adjacent to Fort Stewart, Georgia, USA. The Beluga Sturgeon is the largest freshwater fish in the world. They are an ancient 'dinosaur fish' whose ancestors date back 78 million years. Sturgeon depopulation is occurring in the Caspian Sea - a natural and primary source of the world’s caviar. The population in the Caspian Sea is almost depleted. The Beluga Sturgeon (Huso huso) is the biggest freshwater fish in the world.The largest Beluga ever caught weighed 1,571 kg and was 7.2 m long. The population appears to be stable or possibly increasing. Lake sturgeon were once abundant throughout the Great Lakes system until overfishing in the 1800s and early 1900s decimated their populations. It is extirpated from the upper parts of almost all the European spawning rivers (e.g. Raspopov (1993) estimated that beluga sturgeon in the Caspian become sexually active every 4-8 years for females, and every 4-7 years for males.
Beluga sturgeon are some of the oldest fish in existence, thought to be over 250 million years old.

The population appears to be stable or possibly increasing. The eggs of a female Beluga Sturgeon (also known as roe or caviar) sells for an average of $7,000 per kilogram Beluga whales are also culturally important to indigenous communities in the Arctic. Whales, like the beluga, are at the top of the food chain and have an important role in the overall health of the marine environment. But these days, the Beluga species are critically endangered. Most notably, Black Sea sturgeon (beluga) are already on the verge of extinction because of beluga sturgeon caviar being of such high-quality.

The Altamaha River supports one of the most robust Atlantic sturgeon populations in the Southeast, The number of juvenile sturgeon produced by these spawning runs ranges from 1,000 to 2,000 individuals occupying the river each year, 87 percent of which are 1 to 2 years of age. Researchers are especially concerned about beluga sturgeon as the worldwide population has declined by more than 90 percent over the last 20 years.
