June 16 spawning - first selection
We've completed first selection on the June 16 kohaku spawning fry that we harvested recently.
The fish were larger than we typically first selection at and that helped a great deal during selections - simply because it was easier to see the detail on the fry.
My overall impression is that the quality was lower than with our trusty okawa female - the one that's produced 2 baby champions for us. But, when I look at the stats at the end of selection - I've kept around 1000 out of 5000 harvested. so, much higher keep rate than normal, and that is in part because I allowed far more tolerance than normal over selection traits to give me a chance to review a wider range of the fry from 1st to 2nd selection as I learn more about the new brood set. it's also in part because there were enough fry with a pattern... so, if I took an optimistic perspective... it bodes well I was able to find that proportion that were worth a go.

Once complete.. I had to change the bottom drain covers on two tanks so that the fry wouldn't go down the drains... We covered the covers with a netting - which we'll remove in a few weeks when the fry have grown a few cms.

Next up, I need to select through this lot.... the fry from our May 16 spawning. these are from the same brood set as our july 14, and may 15 spawnings.

| These fry are from the May 16 spawning - the one where the spawning went incredibly well, but the ponds became toxic and we turned to contingency plans in an attempt to salvage a harvest. this is a picture of what we've achieved through contingency plans... and I'm interested on the count up when we select to see how we did. |
