Stripping Senegalese sole sperm for in vitro fertilization at Safiestela Ltd.
The project REARLING, funded by the Portugal 2020 program, Compete 2020, and the European Union through FEDER/ERDF, has established the sustainable aquaculture production of Senegalese sole through the implementation of biotechnologies that removed the bottleneck in the species reproductive control to close the biological cycle in captivity. The project brought together Safiestela Ltd., IRTA and RARA AVIS BIOTEC SL to finetune and adjust technologies for the control of sole reproduction.
Until recently, the production of Senegalese sole juveniles relied on the capture of wild broodstocks from unsustainable fisheries as large-scale egg production from hatchery-produced breeders had failed, either through attempts to obtain natural spontaneous spawning or through in vitro fertilization. The principal problem that is frustrating the implementation of in vitro fertilization is the low quantities of poor-quality sperm, which is usually collected from sole males.
