I'm now concerned enough to move egg strands from the big pond to the production pond whether they are fertilized or not. (Virtually no males or literally no males in the big pond). After all if I don't get fertilized egg strands in the production pond, I have to wait a whole year to do it again. Still only one egg strand retrieved from broodstock pond even though there are 20 gravid females and 200 males in that pond! Must have moved them too late and stressed them.
However I'm getting 3 to 5 new egg strands in the big pond every morning. What can I say? As soon as I think I've got things figured out the fish refuse to read the book.
