How Fresh Caviar Works

You cast the line and just as the lure slaps the water’s surface, something snaps at the bait. Soon you’ve landed a female fish, ripe with eggs. Voila! Break out the toast triangles: You’ve got caviar, the A-list appetizer.

Not so fast. Yes, the unfertilized eggs of nearly any female fish can be separated from their egg sacs, washed, salted and eaten. But true caviar fresh, according to the U.S. Food and Drug Administration rulings, comes from sturgeon only. And, as connoisseurs the world over will attest, the delicacy is a sought-after, often expensive and frequently controversial commodity seasoned with mystique — making sturgeon eggs more than the mere sum of their parts

Given that caviar is, at its most basic, simply the eggs of a fish, it’s somewhat surprising this roe has risen to royalty status. In some parts of the world, caviar is currency. In others, it is a status symbol revered for its texture and taste. Globally, the legal caviar trade prompts an estimated $100 million to change hands annually; illegal trade increases that number tenfold [source: CITES]. Today, the United States consumes the lion’s share — about 60 percent — of beluga caviar, the priciest variety produced by a prehistoric-looking fish headed for extinction [source: Pew Trusts]

However beloved by gourmands, the subtle variances of caviar are often misunderstood. The size and flavor of caviar is as distinct as the fish from which it is harvested, and as diverse as the methods used to preserve and store the fragile orbs. Saying “I like caviar” is like saying “I like every flavor of jelly beans.”

What Kinds of Fish Make Caviar?

The sturgeon is a lumbering, toothless fish with a decidedly prehistoric appearance whose eggs are harvested for caviar

The sturgeon is sometimes called a “living fossil” because of its few adaptations through the millennia. The Acipenser family tree includes 27 sturgeon, although genetic markers have scientists disputing the exact number of distinct species. Some sturgeon, like the beluga, live a century or more and continue to grow — in fact, one beluga reached a record 4,500 pounds and 28 feet long, which is about the size of a motorhome

The eggs of each species of sturgeon, except the largely poisonous green sturgeon, can be used for caviar. However, only three sturgeon species — the beluga, osetra and sevruga — supply most of the world’s caviar. These species live in the Caspian Sea, which is bordered by five nations including Iran, Kazakhstan and Russia. Other bodies of water producing significant amounts of caviar include the Black Sea and Sea of Azov

Sturgeon are anadromous, which means they can live in both salt and freshwater. They prefer, however, to keep one fin in both worlds. Most live in tidal estuaries where salt and fresh waters collide, then swim in rivers to spawn. Sturgeon annually return to the same place to lay their eggs, and their predictable swim makes them easy targets. When caught, most sturgeon won’t fight; they’re simply resigned to their fate

Caviar’s premium price, coupled with demand, makes the sturgeon attractive to legal fisheries and poachers alike. Decades of overfishing mean fewer mature fish and scant opportunities to reproduce. This cycle is evident in the Caspian Sea’s dwindling beluga population, which has dropped more than 90 percent [source: Science Daily]

Within the last 10 years, a number of efforts have attempted to assuage the sturgeon’s collapse. Imported beluga caviar was banned in the United States, the beluga sturgeon was placed on the nation’s endangered species list, and international coalitions pushed for stringently reduced fishing quotas. Few measures, however, held up to the continued demand for caviar
