Air spawning trial in Tolmin

Ákos has participated in a trial of air spawning of marble trout (Salmo marmoratus) at the fish farm of the Angling Club of Tolmin conducted by Dr. Radosław Kowalski and his team – Beata Cejko, Sylwia Judycka and Michał Blitek – from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn, Poland on January 15-18th, 2017. Dr. Kowalski has applied and perfected this technology in many salmonid species previously and it worked fine on the marble trout, as well (see the video below). Air spawning is claimed to be less stressful for the fish than manual stripping, results in higher egg quality and more complete removal of eggs from the body cavity.
In addition to the air spawning trial, experiments were conducted on the cryopreservation of marble trout sperm. Information was exchanged by the Slovenian and Polish partners on the production of fish products such as trout caviar and trout pâté. Finally, we enjoyed the company of our Polish partners at our department in Gödöllő, too. We conducted experiments on the cryopreservation of common carp sperm which was also a good test of our carp broodstock for sexual maturity.
We would like to thank our partners in Slovenia and Poland for this truly international cooperation. We very much hope to continue this work in the future.
