| Abstract |
We assessed the effect of short-term (4.7-75.3h) storage at low temperature (approximately 1°C) on the viability of sea lamprey (Petromyzon marinus L.) gametes. Hatching success decreased with storage time, but more than 20% eggs hatched even after 75.3 h of preservation. However, storage time drastically reduced the survival rate to the burrowing stage (i.e. the last prelarval stage), which decreased from 76% when the gametes were stored for 4.7 h to 0% after 75.3 h of storage. |
