Major caviar producers have agreed to slash exports this year, a move almost certain to drive up prices of the luxury sturgeon roe delicacy.
Christmas shoppers will have to dig deeper into their pockets
Caspian Sea states Azerbaijan, Iran, Kazakhstan and Russia agreed to cut their combined exports to 113,554 kg (250,200 lb) from 146,210 kg.
Exports of beluga, the most expensive variety, will be halved to 4,425 kg.

The export cut was agreed at a meeting of producers in Bangkok on Friday.
