Perhaps wild carp can teach us something about Nishikigoi

Carp - Cyprinus carpio

Q/ Why is it easier to catch carp at night than during the day?
Carp are easily scared away by any kind of movement or disturbance on the bankside. At night , when things have quitened down, there's less chance of them being spooked.
Q/ Why are carp found mostly in shallow waters?
This is mainly because water temperature has a marked effect on their breeding rate. Carp do not breed in the deepest, coldest lake and gravel pits, but in shallow waters such as farm pond which warm up quickly.



General info
The wild carp is among the most majestic and beautiful of our freshwater fish, and the most difficult to catch. To Izaak Walton it was 'the queen of rivers'. With an ample supply of food it can grow to a large size to become an extremely strong and tenacious fighter.
Unfortunately, the wild carp is slowly becoming less widespread, not only in Britain but throughout the world. One reason suggested for this is that the introduction of the 'King' carp strain into many habitats has caused interbreeding, thus losing forever the purity of the wild carp stock. However, there is evidence to suggest that with adequate spawning facilities, the true wild carp and the selectively bred 'King' carp will not spawn together.
Probably, the most significant reasons for the drop in numbers have been, with the enormous increase in popularity of carp fishing since the 1950s, the detrimental changes which have taken place in their particular habitats.
IdentificationThe wild carp has a much more slender body, similar in some respects to that of the chub, than the cultivated species, which is often humpbacked and much deeper. In Britain the wild carp seldom exceeds 10 lb. in weight, although a few over 15 1b have been captured, and the maximum, under favourable conditions, is probably about 251b.
Coloration is variable, depending mainly on the environment. Usually, the top of the head and body are dark brownish-blue, the sides bright golden, and the underside off-white near the head, changing to a yellowish near the tail. The dorsal fin has the same colour as the top of the body, as does the upper portion of the tail, while the lower part of the tail often has a reddish-orange tinge. The pectoral, ventral and anal fins vary between slate grey and pale reddish-orange. Variations in colour in individual fish can take place throughout the year, and are especially noticeable during spawning.
Maturity is usually reached between 2-4 years, with the male often maturing earlier than the female. The time taken appears to depend to a large extent upon temperature, for under artificially controlled conditions carp have reached maturity after only 4-8 months.
The wild carp is an adaptable fish, which is capable of living in a wide variety of habitats in Britain. Generally, however, it favours shallow lakes and ponds, rich in aquatic vegetation, and still, sluggish, or slow-moving rivers and canals. Since Britain is at the northernmost limit of the area in which carp reproduce, it follows that, in general, the distribution and occurrence of the species are greater in the south of these islands than in the north. The most northerly wild carp fisheries in the British Isles are Brayton Pond, near Aspatria in Cumbria, and Danskine Loch, in Scotland.
Adult wild carp typically inhabit warmer environments, such as shallow areas of ponds and lakes, or slack eddies in rivers, usually where there is aquatic vegetation

(Cyprinus carpio)




Leather Carp - 31.5 LB

The mirror carp is slightly different in shape to the common carp. As a rule, mirror carp have a fuller, more rounded shape. A huge swollen belly is not uncommon in some larger specimens, although some can be quite slender if food is not plentiful. Its golden brown skin is covered with varying amounts of different sized scales, these fall into six different scale pattern groups:
  1. The fully scaled mirror :Fully covered in different sized scales.
  2. The Leather carp :Completely scaleless, occasionally has a line of small scales on its sides.
  3. The Plated mirror : Has a one or a group of huge scales on each side.
  4. The Scatter scale : Normally has a line of scales running both sides, flanking the dorsal fin and odd scales dotted at random.
  5. The Linear mirror :Long line of scales along lateral line, small groups of scales at tail and dorsals.
  6. The Star burst mirror :Basically a scatter scale with the addition of small scales in a star-burst pattern on the lower half of the body.

I have learned that that is one ugly carp.

It has no confirmation, no color and no pattern.

Russ,
Just be thankful the Japanese didn't take a liking to the grass carp.

I found it surprising how many colors occur in the wild carp. I find it interesting they can reach maturity in 4 months under artifically controlled conditions. Also that color can change during spawning.

I agree with you Mitch, I did not think there would be any variations at all, in color or otherwise. If you think about it though, that is how it all started with the Japanese. They took those variations and developed them.

Here's the in between.

Not hard to see where Chagoi comes from.
