Sera

Sera

The birth of sera took place in 1970. Josef Ravnak, who already had gained excellent reputation with the sales live food, founds his first enterprise and revolutionized the branch by using the freeze drying procedure, which was new at the time. This allowed conserving food organisms such as bloodworms, Tubifex, Artemia shrimps and Daphnia while optimally preserving the nutrients and vitamins.
