Yamatonishiki Harvest

We had a couple of friends join us for selection one of whom was Herbie although I didn’t get any pics of Herbie in action unfortunately.

The regulars to Koi Quest will have seen pictures like this in years gone by but I thought I’d do some new ones for the benefit of those that haven’t seen it all before.

We dragged the net through at about 8.30 am (this is actually the second time we have pulled the net through this pond). We use a net which stretches from one side of the pond to the other and carefully drag it from one end of the pond to the other.

Still netting!

Once it is at one end the net is gathered in until all the young Koi are caught up.

Sometimes we get some great diving beetle larvae in a pond and they are not good as they eat fish! Harvesting doesn’t just get the fish out though, it also gets the beetles out.

The fry are then caught up in a pan net, transferred to a bucket and then placed in a waiting transport tank that has oxygen bubbling into it.

Once all the fry are in the transport tank it is driven round to the selecting tanks and the fry are transferred, using the pan net again, into a holding net suspended in a large tank with lots of air bubbling into it.


After that we get selecting! We didn’t count all of these fry but it took until mid Friday morning to finish selecting the ones we wanted to grow on. We usually aim to put about 3,000 back and that’s almost exactly what we did, which is great. 3,000 is a good number for the size of mud pond that we have and that usually works out at 10% or less going back into the mud pond for a further month before second selection at 2-3 inches. I didn’t get any pictures of the keepers this time round either as we were in a bit of a hurry to harvest and select through some Shusui on Friday. Myles joined us for that one and as always was a big help – thanks Myles.

I’m really looking forward to doing second selection on these Yamatonishiki. For those of you who aren’t familiar with Yamatonishiki, they are basically a metallic Sanke and those that we bred are also Doitsu rather than fully scaled. They are very popular and produce several different varieties in one spawning. By breeding Doitsu Yamonishiki you get Doitsu Platinum Ogon, Yamabuki Ogon, Gin Bekko, Kin Bekko (Tora Ogon), Kikusui, Hariwake and Yamatonishiki. We have to produce several different varieties here and don’t have the luxury of specialising in just one so Yamatonishiki fit very well into our selection.

Two ponds of Sanke to select through next week and two lots of Showa fry to go out from the spawnings that we did earlier this week.

Lots to do!
