To “save” endangered salmon, scientists use 20-year-old frozen sperm

Another half baked idea to try to improve the quality and genetic diversity of hatchery salmon.

In an effort to get a wide range of genetic diversity, the Spruce City Wildlife Association hatchery is using a mix of the decades-old sperm, also called milt, and combining it with more recently collected milt, in hopes of bolstering the number of chinook in the Endako River.

“I think that this is pretty groundbreaking stuff,” said Dustin Synder, vice-president of the association.
