Abstract

Milt and testes were obtained from European catfish (Silurus glanis) and refrigerated. Viability of stored spermatozoa was prolonged by keeping them in plastic bags, inflated with pure oxygen and moistened with water. Further prolongation of storage time was achieved in samples diluted with immobilizing solution. Most successful was preservation of testes under oxygene atmosphere: more than 80% of activated spermatozoa were motile after 29 days and 50% motility was observed on 37th day of storage.
