Fry update

We are half way through the season and have worryingly few fry at 1 inch to show for it.

Both ponds outside are in use - but numbers of hatchlings seem too low. The one that have made it this far are large enough to gorge themselves on the clouds of daphnia but I fear too many didn't make it this far.

We have a test batch of around 100 of the hatchlings from sharkey's spawning coming along nicely in a tub in the Polytunnel - and whilst it's great to see them growing so well, even at this early stage I am very worried about the quality . I can tell by the variation in colouring that we are probably low in the percentage that will end up with a pattern.  We will wait until they are at first selection size to confirm the finding.

So, as things stand:

- we have a few thousand (at most) 1 inchers from the May spawning of our trusty parent set. 



These fish have been reared indoors using techniques we've tried for the first time this year.  They are finally at 1 inch and first selection size .  We've taken it slow and steady with them - feeding regularly but also mindful of staying within the limits of the filter.

We've moved them into the grow on system, into the green vortex tank . In a normal year - they should be 2 to 3 inches by now !  I'm not too worried by that because we have plenty of time to grow them into good sized Tosai. I just hope we have one or two in there that make it worthwhile. 

- on the fry ponds outside ; first, the bottom pond. We filled this pond wth hatchlings from the Sharkey spawning about a week and a half ago.  We can see fish in there but not that many :-(

- the top fry pond outside ; again, filled with hatchlings from Sharkey spawning.  Numbers in this pond are even lower than the other pond . With the concern I have over the pattern ratio from this parent set, and with so few hatchlings in this pond - I am considering emptying the pond and giving it another go. It's a risk because there may not be time to cycle the pond in time - but it may be worth the risk because there is not much to lose.

So, I will probably make my first attempt to spawn my new takigawa 3 step this weekend. And at the latest, the following weekend .
