Celiotomy to collect spermatogonial stem cells in Brycon orbignyanus for species preservation [PDF]
Animal ReproductionAbstract Surgical techniques in aquatic species are underdeveloped, despite these species comprising a significant superclass among vertebrates. In the context of species preservation, studies involving the use of reproductive tissues typically involve the euthanasia of donors.

Ultrastructural features and differentiation of the spermatids in Brycon orbignyanus during the spermiogenesis [PDF]
, 2000 Spermiogenesis in Brycon orbignyanus may be divided in four stages, which consist mainly in reduction of cytoplasmic, nuclear and cellular volumes and compactation of the nuclear chromatin, whose stages of the process occur simultaneously. At the end of the spermiogenesis, when the spermatids reach high levels of differentiation, the nuclei become more
