Abstract
Abstract
We developed an easy, efficient, and cheap protocol for zebrafish sperm cryopreservation carried out on dry ice (20 min) using simple composition solution (200 mM glucose, 40 mM KCl, 30 mM Tris, pH = 8.0). The average efficiency of the present cryopreserve method was between 10% and 20% (expressed as fertilization rate). The experiments were conducted and repeated at two different locations, in different countries, yielding very similar results, showing the reproducibility and applicability of the method.
