When did the pallid sturgeon become an endangered species?
Pallid sturgeon
Though never believed to be common, pallid sturgeon populations rapidly declined during the late 20th century and the species was listed as endangered on September 6, 1990. The U.S. government and most of the states with pallid sturgeon populations have commenced restoration efforts to save the species from extinction. Wild reproduction of pallid sturgeon is rare to nonexistent in most areas; therefore, human intervention is needed to ensure the survival of the species. Pallid sturgeon were previously considered a prized trophy game fish species, until their numbers declined and they were placed on the endangered species list. All captured pallid sturgeon must now be released back to the wild. The species was known for being very palatable and the roe from females was used as caviar.
Mary River turtle
This species is currently listed as endangered under Queensland's Nature Conservation Act 1992, and under the federal Environment Protection and Biodiversity Conservation Act 1999. The international conservation body IUCN lists it as endangered on the IUCN Red List. It is also listed on the Zoological Society of London's Evolutionarily Distinct and Globally Endangered list, part of the EDGE of Existence programme. It is Australia's second-most endangered freshwater turtle species, after the western swamp turtle ("Pseudemydura umbrina") of Western Australia. Mary River turtles were listed amongst the world's top 25 most endangered turtle species by the Turtle Conservation Fund in 2003.
