Summary

Milt of brown, rainbow and brook trout was cryopreserved. Activity of aspartate aminotransferase and acid phosphatase was assayed both in supernatants and in spermatozoa obtained from thawed sperm samples; additionally, post-thaw motility was evaluated. Enzyme activities differed according to fish species and were strongly affected by the type of cryoprotectant used. The motily of thawed sperm, determined microscopically, provided some information on the cryopreservation efficiency of trout milt.
