Looks like this year will be a botch. Night time temperature now dropping too low taking water temperature into low 70's. That coupled with shorter photoperiod is dropping the need to breed.
The fish will be transferred to tank indoors where spawn should be realized quickly with elevated temperature and longer daylight. The resulting brood will be reared indoors.
Vacated stock tank will be stocked with about 50 larvae from brood currently being reared by Coppernose BG above. I have already started pushing for a stronger plankton bloom by adding some alfalfa.
It is very likely what is produced in the coming weeks will be large enough to spawn late next spring when conditions are more realistic.
