Breeding pair selected

MelanicPosted by Mikael Norberg Tue, August 04, 2009 21:57:25

Three days ago my black moors bred. I discovered a few eggs at the bottom and tried some handspawning, without getting any eggs. But now I’m pretty sure my normal eyed moor is a male. I also think I’ve got two females among the others. I selected the best one and put her with the male in their own aquarium. Lots of earthworms and clean water now…

Calico cross

CalicoPosted by Mikael Norberg Thu, July 30, 2009 23:24:27

When I drawed up the plans for breeding as many colours of wakins as possible, calicos where one of the first to go for. I had an old very blue female shubunkin and bought some calico ryukin males. They spawned and produced about 5000 fry. When culled down to about 40 I’m still not satisfied with the amount of blue colour. Next generation will be culled harder for blue (black) pigment in an early stage.

As expected all fry is single tailed but I did cull two twintails at an early stage. Some twintails should appear in the next generation.

Here are some of my Sunspot youngsters. Note the black pigment that might be unstable and the yellow-orange colour.

Golden nuggets

Copper h-scalePosted by Mikael Norberg Thu, July 30, 2009 22:20:49

Earlier this year I found two yellow hammerscaled goldfishes at a local fish store. At the time I did not really knew what to do with them since my plan was to work with goldfish colours only. After some thinking I decided to cross them with a chocolate oranda to make chocolate hammerscales. I later began to use the term copper since hammered copper sounded more plausible.

The bunch of young h-scale x chocolates are my most vital spawn this year. I have only culled a handful of odd ones. I did a cull for size some month ago and now the remaining youngsters are about tree centimetres. There are about 35 of them left and I ruthlessly cull the ones that start turning colour.

Chocolate picture to be added

As expected no one turned out hammerscaled or chocolate since the genes are recessive and four times recessive. All of them are instead wildcoloured and with normal scales. The culled ones that turns colour looks pale yellow-orange.

The oranges with black spots belongs to the Sunspot line.

In the next generation I expect very, very few of the fry to show some kind of chocolate colour. ¼ of them could also be hammerscaled and then I’ve got hammered coppers and perhaps some golden nuggets (clean yellow colour instead of red under the thin gray layer).

Feeding time!

At the picture: red/white wakins, pinky matts, calicos, culled sunspots, yellow hammerscales and chocolate x yellow hammerscale.

Inspired by the Sunburst goldfish at The Goldfish Shop I started a new line of breeding this spring. Since I at the time did not have any yellow mock metallics I decided to try with two female calicos ryukins and my yellow common goldfish male, who by the way showed a good Fukurin area at the back. When I stumble across this fish at Youtube I knew exactly what to breed for. The Sunspot line was started.

After some months of trying to get the chosen trio to spawn they finely bred. I’ve got about 200 fries only, but the quality turn out to be very good. I culled all metallics at an early point ended up with about 100 nacreuos showing various degrees of yellow. Later I culled the ones showing no or little yellow-orange colour leaving me with about 50. Finely I selected 20 of them showing good black (and blue) pigmentation at two centimetres.

I expect the black pigment to fade away due to demelanizing genes from the yellow father. I will not cull the ones who demelanizes first because the yellow colour is not really satisfying being a bit orange. Some culling towards yellow will be done. I think the yellow colour will be better and the black colouration will be more stable in the future generations.

I’m very pleased with this cross and really looking forward to see how it develops. When I got it somewhat stable I plan to add albino to this line. Problem seams to be no one knew where to find albino goldfish.

The goldfish blog

UncategorizedPosted by Mikael Norberg Mon, July 27, 2009 21:49:30

I started this blog to share information about breading and developing goldfish. I’m mainly interested in the goldfish colours and scale types. I try to keep my fishes twin tailed like wakins to differ them from koi. Since Sweden is not a big goldfish country I guess English is the best language to use and also good practise for me.

This is my goldfish house. The picture is taken in the winter/spring of -09.

Experimental breeding

UncategorizedPosted by Mikael Norberg Sat, July 25, 2009 23:31:02

I have found some yellow bluebelly goldfishes among normal scaled yellows at different pet shops in the Stockholm area. Some of them were also hammerscaled and not so pretty, one were very metallic like a gin rin koi and only two were bluebellied, not hammerscaled and very matt. I bought the two last ones and right now I plan to breed them to several other types and colours of goldfish.
