The United Nations has lifted a ban on the sale of caviar, the treasured delicacy that is in serious decline.
Sturgeon stocks are still falling
An almost total ban was imposed a year ago because the fish from which caviar is taken, the sturgeon, is disappearing rapidly in the Caspian Sea.
Five countries bordering the Caspian will now be allowed to resume fishing.
The UN agency, Cites, published quotas for all types of caviar for 2007, but postponed a decision on beluga, the most expensive variety.
Virtually all trade in caviar was banned last year because the main producers - Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan - failed to meet Cites' requirements, like providing details of stock levels.
Although sturgeon stocks are still falling, the five countries will be allowed to sell 96 tons of caviar in 2007 - 15% below the level set in 2005.
"The decision taken by Cites last year not to publish caviar quotas has undoubtedly helped to spur improvements to the monitoring programmes and scientific assessments," Cites Secretary General Willem Wijnstekers said in a statement.
Some 90% of the world's caviar comes from the Caspian Sea.
But the illegal trade in caviar, which can sell for up to $9,500 (£4,800) per kg, is thought to be as big as the legitimate one.
It is estimated that caviar stocks fell by up to 90% in the early 1990s because of over-fishing, raising fears that sturgeon would be wiped out.
