The Bulgarian fish research institute in Bolyartsi, Plovdiv region, has a sturgeon-breeding facility that plants young sturgeon in the Danube river. Bulgaria’s Agriculture Ministry has proposed a new rule for financing the planting operations, under which the fishermen, who have received a licence for catching and exporting sturgeon and sturgeon caviar, will pay a fee for the fish planting, reported the Bulgarian News Digest.
The technique is currently practiced with other fish breeds, such as trout, but not yet with sturgeon, from which caviar is made.
The Bolyartsi institute also experiments in breeding sturgeon in fisheries for industrial use.
