Maybe if a German scientist's practices to be effective and all-consuming, the fate of this ancient fish extinction during which he obtained of caviar in the world, a lot of fans.
Angela cooler to NPR national radio network the United States has said that during nine years of research has designed a new system for the production of caviar goes hope demand for black market caviar.
New way of being in a fish-breeding Center in the town of لوکستت in Germany runs include reviews of ultrasound with fish eggs. If the egg is reached, a particular protein to several times a day to the body of the fish eggs and then injected it to extract.
According to Mrs cooler this protein causes the delivery mode and the release of seeds from a bag in the belly of the fish. At this point the eggs, caviar with rubbing the belly slowly, outside.
