Use of AquaBoost™ Extender seems to have a positive effect on short-term storage of Ballan wrasse (Labrus bergylta) milt. Milt diluted with extender in the FHF-project, “Production of ballan wrasse” showed an average fertilization rate of 89.9% after 5 days of storage.
As a part of the project funded by FHF (Norwegian Seafood Research Fund), Cryogenetics has contributed with our products and knowledge for treatment of milt to get a best possible fertilization result. Milt from Ballan wrasse was diluted with two different extenders supplied by Cryogenetics. Part of the diluted milt was used for fertilization immediately after stripping and dilution, and part was stored for 5 days and then used for fertilization. Due to lack of females releasing eggs, there are no results for milt stored for longer than 5 days. The fertilization trials were performed with the participation of Dr. Ingrid Lein and Nofima at Sunndalsøra.
