title: Deep - freezing of rainbow trout Salmo gairdneri sperm at varying intervals after collection.
abstract: Rainbow trout semen cryopreserved 0.33, 5, 60 and 360 min after collection gave postthaw fertilization rates of 71.9, 68.4, 65.5 and 49.1% of eyed eggs, respectively. The corresponding result obtained with chilled semen stored for 2 wk under oxygen was 96.9%. This suggests that the freezing of rainbow trout semen should be done immediately after collection.
