Biotechnology: surrogate broodstock produces salmonids.
A worldwide decline in the number of wild salmonids calls for strategies to restore endangered populations. Here we show that germ cells can be transplanted between two different salmonid species, with the subsequent production of xenogenic, donor-derived offspring. This pioneering xenotransplantation technology may eventually find applications in facilitating the production of commercially valuable fish, as well as in species conservation.
