Cryopreservation and regeneration

We offer cryopreservation services, which comprises of sperm freezing and in vitro fertilisation.  This is done on site by experienced senior technicians, and the frozen sperm samples are held both on site and off site at the Royal Holloway Free UCL: Biobank. 

This service is offered to both UCL based and non-UCL based researchers who wish to archive any genetic strains for future use.  Any fish that are booked into the system must meet specific criteria:

• Males must be young (3-6 months recommended

• Males must be capable of breeding

• Number of fish provided must be between 1-6 individuals

Genetic information must also be provided, such as:

• Allele numbers

•  Proper nomenclature used for strain names
