World's Most-Prized Fish Sold for $3.1 Million at Tokyo Auction

World's Most-Prized Fish Sold for $3.1 Million at Tokyo Auction One of the world’s most expensive fish just got pricier. A 278-kilogram bluefin tuna sold for 333.6 million yen ($3.1 million) at a Tokyo fish market Saturday. The record price -- which equates to about $5,000 a pound -- is more than double the previous high set in 2013, according to Masayuki Fukuda, an official in charge of trading operations at the Tokyo market. The record-topping fish was caught off Oma in northern Japan.

Lake sturgeon , our elders by some 150 million years, have a bright future — if Americans ignore voices of the past . In “The Song of Hiawatha” As a nation we clearly are acquiring what Aldo Leopold called an “ ecological conscience.” All who feel a sense of hopelessness about humanity’s future and

Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. Their evolution dates back to the Triassic some 245 to 208 million years ago. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus.

For millennia, the Hudson River and its estuary teemed with Atlantic sturgeon, giant fish of an almost unfathomable evolutionary age. These anadromous fish — a term for fish that spend their adult lives in the ocean but swim into fresh water rivers to spawn — were once so plentiful in New York’s waters that well into the 19th century they were referred to as “Albany Beef,” the food of the workingman.

Sturgeon were just one component of an incredibly rich, productive and diverse marine environment that has provided food security, cultural identity, and the foundation of our economic wealth for every successive wave of settlement in New York since the Lenape Indians established their seasonal fishing villages along the shores of the islands that now make up our city.

Million dead fish cause environmental stink in Australia

Million dead fish cause environmental stink in Australia As many as a million fish are believed to have died along the banks of a major river system in drought-battered eastern Australia, and the authorities warned Monday of more deaths to come. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The banks of the Murray-Darling Rivers are thick with rotten fish, with officials putting the number of dead at hundreds of thousands and saying the toll is likely closer to one million.

The study found a 70-90 percent decrease in the age of plant waxes leaking out of soils over the past 3,500 years, a

For many of us , this fish ’s primordial appearance might be unsettling. A decade after a ban on sturgeon fishing all along the Atlantic coast, the fish population had failed to recover and in 2012, the Delaware River sturgeon were among several populations listed as endangered by NOAA Fisheries .

Sadly, the demand for sturgeon meat to feed the growing population of the New York area was surpassed only by the market for their eggs. Their caviar sparked a “black gold rush” in the 1800’s with a predictable result — the New York sturgeon fishery, which landed close to 7 million pounds of sturgeon at its peak in 1887, declined to a mere 20,000 pounds in 1905.

The addition this week of several Atlantic sturgeon to the New York Aquarium’s collection asks New Yorkers to consider this story of unsustainable consumption of natural resources. Multiple attacks at every point of the fish’s life cycle led in the last several decades to a population crash, culminating with the Atlantic sturgeon being listed under the Endangered Species Act in 2012.

Sturgeon - An Ancient Species. Sturgeon belong to one of the most primitive groups of bony fishes . Certain accounts state that sturgeon were so plentiful they actually clogged rivers during their spawning runs. Many species of fish look alike, making it difficult to tell them apart.

If we are to learn from that experience, the details are instructive. As the city grew, so did the threats and pressures we placed on our natural heritage in the form of dams, dredging, pollution, and ship strikes. None felt that impact more than these slow growing, late maturing, primitive fish that can reach lengths as long as 14 feet and live as long as 60 years.

But there’s another story in this city nearly as old as over-exploitation: the action of concerned citizens and organizations determined to save the wildlife of New York.

With the Atlantic sturgeon population vastly diminished by the late 1980s/early 1990s, state and local government agencies, academic researchers, and private conservation non-profits like the Hudson River Foundation and the Wildlife Conservation Society (WCS) worked to understand the sturgeon’s life cycle, habitat needs and complex migration patterns.

The lake sturgeon (Acipenser fulvescens), also known as the rock sturgeon , is a North American temperate freshwater fish , one of about 25 species of sturgeon .

Through the acoustic tagging work WCS and others began in 2006, we have learned valuable information about the journeys of adult sturgeon up and down the Atlantic Coast and into the tidal reaches of the Hudson, and this information has been used to better protect these ancient fish in the efforts to bring them back from the brink.

Thanks to an aquaculture study by the Maryland Department of Natural Resources that has now been discontinued, five of these famous fish—each five to six feet long and weighing over 120 pounds—have come to the New York Aquarium, where they join innumerable other local marine species, from tiger and sandbar sharks to loggerhead turtles.

The Atlantic sturgeon provides a cautionary tale of overfishing. But it also provides a fantastic reminder of the work of so many New Yorkers to protect our fantastically diverse coastal species, which in addition to those mentioned above include surprising numbers of whales, seals, and other marine mammals; shorebirds; and oysters that — in another tale of abundance and precipitous decline — once provided our best defense against the storm surges now gaining in strength in a changing climate.

With the introduction of sturgeon, aquarium visitors will have the rare opportunity to see these representatives of an ancient lineage, and learn of their special place in our state’s history. Perhaps even more importantly, they have an opportunity to expand their knowledge of our local seascape and what is required for its conservation — including their voices and advocacy.

Start your engine, U.S. justices tell hovercraft-riding moose hunter.
The U.S. Supreme Court on Tuesday ruled for the second time in three years in favor of an moose hunter over his challenge to a federal ban on hovercraft on National Park Service land in Alaska in a case involving federal control of public lands. The ruling is limited to a specific federal law that addresses lands in Alaska and does not apply to other states. Sturgeon's lawyer did not immediately respond to a request for comment. In March 2016, when the case first reached the Supreme Court, the justices ruled unanimously against the federal government and directed the San Francisco-based 9th U.S.
