Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years. But a new study by University of Michigan researchers and their colleagues reveals that in at least one measure of evolutionary change–changes in body size over time–sturgeon have been one of the fastest-evolving fish on the planet. "Sturgeon...

Illegal Trade Of Caviar Curbed By International Regulation
2012-07-26 05:56:52

DNA testing of retail black caviar conducted by scientists from the Institute for Conservation Science at Stony Brook University and American Museum of Natural History indicates trade policy can help reduce the incidence of caviar mislabeling Research that used mitochondrial DNA-based testing to compare the extent of fraudulent labeling of black caviar purchased before and after international protection shows conservation benefits. A team of scientists from the Institute for Conservation...

A fisheries watchdog said on Monday that Russia has resumed sturgeon caviar exports to the European Union (EU) after a nine-year ban. Alexander Savelyev, a spokesman for the Federal Fisheries Agency, said that Russia has decided to allow exports to Europe of up to 330 pounds of black caviar from farmed fish as "a symbolic volume." "The goal is to break the ice which has formed over the past nine years when not a single permit was issued for exports of the black caviar from Russia," Savelyev...

Study of ocean migration indicates that local management of the population may be insufficient and supports recently proposed listing for Atlantic sturgeon under US Endangered Species Act A first-of-its-kind study that tracked the oceanic migrations of adult Atlantic sturgeon that were caught and tagged in the Hudson River discovered that these fish move vast distances in the Atlantic Ocean, traveling as far south as Georgia and as far north as Nova Scotia, Canada. The findings indicate that...

While trying to find a DNA-based test to determine the sex of lake sturgeon, Purdue University researchers found that the sturgeon genome contains trematode genes that didn't originally belong to it and may harbor a protozoan parasite that causes a sexually transmitted disease in humans. Genetics professor Andrew DeWoody and postdoctoral associate Matthew C. Hale found the parasite and pathogen genes while analyzing DNA from the gonads of lake sturgeon, a species that is on the decline...

The world's largest global environmental network announces that more sturgeon species are critically endangered than any other comprehensively assessed group of species The International Union for the Conservation of Nature (IUCN) today formally announced the reclassification of beluga sturgeon in the Caspian Sea as "critically endangered" on its Red List, providing strong evidence that fishing and international trade should be halted and a stock-rebuilding plan should be initiated...

Joint study by American and Kazakhstani scientists shows reducing adult mortality, rather than relying on hatchery supplementation, is key to recovery of beluga sturgeon A first-of-its-kind study of a Caspian Sea beluga sturgeon (Huso huso) fishery demonstrates current harvest rates are four to five times higher than those that would sustain population abundance. The study's results, which will be published in an upcoming issue of the journal Conservation Biology, suggest that conservation...

The U.S. Fish and Wildlife Service says the shovelnose sturgeon should receive protection as a threatened species in certain areas because of its appearance. The St. Louis Post-Dispatch said Monday shovelnose sturgeon are sometimes confused with young pallid sturgeon, which are an endangered species. Fish and Wildlife Service officials proposed last week that due to physical similarities between the two species the shovelnose should also be federally protected in areas where the species...

Canada's University of Manitoba is looking for a home for three endangered fish, seized from smugglers, that can grow to 13 feet and 100 pounds in a century. The fish are young Black Russian sturgeons seized two years ago by the Canadian Wildlife Services from smugglers trying to sell them as aquarium fish, biological sciences Professor Terry Dick told the Winnipeg Free Press. He said when his department got the sturgeon, they were about four inches long, but are now about three feet long and...

For the first time in more than a century, a sturgeon has turned up in a net in the Baltic Sea, caught by a Swedish fisherman. Ulf Akerlund told the news agency TT that he caught the unusual fish Thursday off Oland, an island on the southeast coast of Sweden. The fish was in the midst of a net full of cod, his usual catch. I had at first no idea what it was, he said. But we surfed around a bit on the Internet and researched in a couple of books and we found out that it was a sturgeon. The...

The Pallid sturgeon (Scaphirhynchus albus) is an endangered species of fish that exists in the waters of the Mississippi and Missouri River and numerous tributaries. In 1990, the U.S. Fish and Wildlife Service placed the species on the endangered species list, as very few young sturgeon had been found in recent years, and also due to the fact that all sightings of the fish had lessened in the preceding decade. The Pallid sturgeon is one of the largest fish found in the Mississippi...

The Atlantic sturgeon (Acipenser oxyrhynchus oxyrinchus) is a member of the Acipenseridae family and is among one of the oldest fish species in the world. Its range extends from New Brunswick, Canada to the eastern coast of Florida. It was in great abundance when the first settlers came to America, but has since declined due to over-fishing and water pollution. It is considered threatened, endangered and even extinct in much of its original habitats. The fish can reach sixty years of age,...

Sturgeon (Acipenser) is a genus of 20 different fishes, of which some twenty different species are known, from European, Asiatic and North American rivers. They pass a great part of the year in the sea, but periodically swim into large rivers, some in spring to deposit their spawn, others later in the season for some purpose unknown; only a few of the species are exclusively confined to fresh water. None occur in the tropics or in the southern hemisphere. In Russia the fisheries are of...
