KOI WATER BARN - Winter Opening

Tuesday to Sunday 10am to 4pm

Sekiguchi Competition Report


Saturday 11th October saw the proud owners of the Sekiguchi Koi purchased earlier this year return them for judging.

When selected the koi ranged from 18cm to 24cm, so the growth rate that had been achieved was impressive with the returned koi ranging from 32cm to over 45cm. Judging was hard, but 4 koi made the final round and then it was down to just two.

The two koi being owned by Jim Litchifeild, and Mike Keyte. After much deliberation and discussion it was decided that for many reasons that a joint prize would be fairer than having to pick one koi, so both of the owners of the koi in question were consulted, and they both agreed that the prize of a Single Sekiguchi Nisai although a dream prize, could be replaced with a selected Sekiguchi Nisai or lower priced Nisai, with each getting there own koi.

So with this decided the prize for the 2014 Julian read Show and Grow was awarded jointly to Jim Litchfield, and Mike Keyte. A full report on the day will be added soon.
