Jerbear,

Why do they have to check for internal hemmorhaging disease and how would it spread to all the offspring? My understanding is that standard practices include spawning each female into a separate bucket and incubating in individual or small lots, and then only after disinfection. Given those two safeguards, would you describe how all the eggs/offspring are at risk?

Also, I've found male steelhead to be very stingy with their sperm compared to salmon. Using 1 buck with 6 hens is a practice I thought was discontinued many years ago now. Maybe hatchery bucks are more generous and shot their entire wad at once, which would make fertilizing more females easier, but not wiser.

Sincerely,

Salmo g.
