| Outline of Final Research Achievements |
This study established a methodology for cryopreservation of whole testes collected from tiger puffer in order to utilize genetic resources of captive wild fish into seed production for stock enhancement. By transplanting cryopreserved testicular cells contained spermatogonial stem cells (SSCs) of tiger puffer, the transplanted SSCs resumed spermatogenesis in grass puffer as surrogate recipient, and ultimately differentiated into functional sperm within the recipient gonads.
