The ones that survived were eyed. We cleaned them off and they survived. |
The trays that weren't eyed became oxygen-starved and died. The reason we couldn't work with them was that they had high cell-division at that stage. You create your own mortality if you handle them. |
They're still living on internal yolk when we release them. They have to learn to feed within one week once they hit the parent stream. They have to live and survive in the wild. |
