In vitro Zebrafish Fertilization using Cryopreserved Sperm

E-mail Print

We find that this works best with two people. One person squeezes eggs from

females while the other person thaws the sperm.

1. Set a water bath to 33ÂșC.

2. Remove cryovial from liquid nitrogen freezer and transfer to liquid

nitrogen-containing dewar flask until ready to thaw.

3. Squeeze eggs from females into 35mm plastic petri dish. If possible, try to

obtain 3 clutches of eggs and combine into one dish. If you can not get

three good clutches within 1 min of your first clutch, then proceed to step 4

(one good clutch is sufficient). Definition of good clutch: >150 uniformly

nice looking eggs (i.e. yellowish, with no white debris indicative of

degradation). Keep dish covered while sperm is thawed.
