Tung Choi Street or Goldfish Street, Hong Kong








Hi,

Photos of kois I saw in Hong Kong during end of October, 2009.

They were gorgeous and very cheap.

PS: See my related goldfish blog for more detailed description.

Best,

Bill

Boost your Koi growth rate from 18% to 50%!

Boost your Koi growth rate from 18% to 50%! through violin music

For those who want their kois to grow real quick!

Scientists have conducted an experiment where kois were subjected to violin music under controlled conditions. They found that those kois which listened to music grew as much as 18% to 50% more than kois under the same conditions without the music treatment.

In order for their test results to be more vigorous, they put the kois that were originally the placebo group (no music) in Experiment 1 to be the music recipient in Experiment 2 and to see if they grow quickly too after listening to music like the other group in the first instance.

In both cases, those kois in the experiments which listened to the violin music grew much more than those that did not, by as much as 18% to 50% more.

Fascinating!

Those who enjoy their music, may start thinking about sharing it with their kois and enhance their growth rate too!

Hmmm, in Alexander Rybak's song 'Fairytale', he was playing the violin!

Fairytale lyrics
Years ago, when I was younger,
I kinda liked a girl I knew.
She was mine and we were sweethearts;
That was then, but then it's true.

CHORUS :

I'm in love with a fairytale
Even though it hurts.
'Cause I don't care if I lose my mind
I'm already cursed.

Matt scaled Koi called Glass red common carp, also Purse red carp and Oujiang coloured carps

Matt scaled koi?

In goldfish, there are three scale types, investigated and detailed first by SC Chen scientifically (1928). They were:
1. Scaled
2. Mottled
3. Transparent

In the UK, the names which have been assigned to described the three goldfish scale groups instead were:
1. Metallic
2. Nacreous
3. Matt

The shubunkins are the mottled or nacreous type of goldfish referred to while 'pinkies' are the common name used for the transparent or matt varieties for their pink transparent bodies and round black iris (button) eyes.

I have for a long time wondered whether in European carps, including koi, ie, Cyprinus carpio, whether the same scale types would occur.

The problem is that coloured carps, especially kois are often patterned, ie, red or black or other patches of colour. They superficially resembles the shubunkins in colour mix, but does not mean these kois are actually nacreous scaled.

Furthermore, I have not read or seen any specimens of matt scaled European carp in the past, and wondered whether they may exist.

I finally just found that there is a matt cyprinus carpio in the world. It is called Glass red common carp. Four such matt specimens appeared in a farmer's pond in Wanan county, China in 1963, the breed has been perpetuated and 84% of the adults are red, the guts and gills can be seen through their transparent bodies in the juvenile stage, just like the orange matt goldfish.

Here's a link to a copy of the article containing an image of a mature matt glass red common carp with its red gills showing through its transparent gill-plates (opercula).

It will be real nice if yellow coloured matt carps (like the sunburst goldfish), the red, the blue coloured matt carps could also be produced in the future. Matt scaled carp specimens should enhance the blue in the shusui kois, in the absence of iridophores in the scales.

The article also described and showed images of a short-bodied form metallic scaled orange common carp called the Purse red common carp (cultivated for around 300 years) as well as the patterned Oujiang coloured common carp (cultivated for 1200 years, much longer than kois), and comparable to some patterned koi in colours.

It is fascinating to see this alternative forms. It will be really great if these matt Glass red common carp and Purse red common carp and Oujiang coloured carp can be integrated to the range of coloured kois we have today, so we can have matt and short-bodied specimens of kohaku, taisho sanke, ki utsuri etc. The short-bodied Purse red form is like the nymph single-tail goldfish, and its size may be suitable for smaller aquariums.

Hopefully these common carp variants:
1. matt scale (Glass red common carp),
2. body type (Purse red carp), and
3. colour (Oujiang coloured common carp)
will be available for creating new koi varieties in the future.
