What are the factors that control and influence the body color of ornamental fish?

1. The body shape and color of ornamental fish are mainly determined by their own genetic factors, but their body color is also constantly changing at different stages of fish growth. The most notable is that there is a "color change period" when the body color of goldfish and koi changes significantly from juvenile to semi-adult stage. This period is a critical period for the formation of fish quality. If they are properly fed and managed, the body shape and color of the fish can be more perfect, and their ornamental value and commercial value can be improved to a higher level.

Second, environmental factors are an important factor affecting the body color of fish. Different water environments have different pH values, dissolved gases, organic compounds, and minerals. Even if it is the same species of fish, it will have very different body colors when grown in different relatively stable water environments. Some fish breeding experts can tell the approximate origin of a fish by looking at it. The main basis is the difference in body shape and color of fish in different places. A typical example is that goldfish from Fujian, Guangdong and other places are generally of better quality and more colorful than those raised in the north.

3. Artificial hybridization variants, such as the colorful red lid, blood parrot, and heart, which have been popular in recent years. This type of ornamental fish has been artificially controlled, with conscious hybridization of the same or different species and strengthening of certain mutant genes, so that its cute body shape and blood-red body color have gradually stabilized. The blood parrot is a hybrid of the red manta ray and the firemouth fish of the Cichlidae family. After a period of selection and optimization, it has become an independent ornamental fish variety.

4. The practice of adding color-enhancing ingredients to artificial compound feeds has been widely used and has certain effects. However, the color-enhancing ingredients added by different manufacturers are also different. There are both natural color-enhancing ingredients (such as corn protein powder, carotene, astaxanthin, etc.) and artificial synthetic substances (such as carotene, carmoisine, industrial synthetic pigments, etc.). According to the group comparison breeding experiment of ornamental fish (goldfish, koi, blood parrots, etc.) by the Feed Department of Wuhan Institute of Technology, corn protein and astaxanthin in natural color-enhancing ingredients have better effects, which are better than other additives such as carotene. The amount of artificial synthetic pigment added is small, and the effect is not obvious. When the amount of some synthetic pigments added exceeds one time, the fish body turns red quickly, and the body color becomes lighter after a few days of discontinuation, and the mortality rate increases. Experiments have shown that for young fish in the color change period, it is not necessary to deliberately add color-enhancing ingredients to the feed, but the crude fat and crude protein content should be high, the vitamin, calcium and iron content should be rich, and it should be easy to digest and absorb, so it is best to feed extruded feed. For fish in the non-color change period, if they are fed with nutritionally balanced feed with reasonable addition of natural color-enhancing ingredients, the fish will generally show obvious color enhancement and color change effects in about three weeks. If they are fed with feed with excessive addition of synthetic color enhancers, the color enhancement effect will be seen in about a week, but it will cause greater damage to the fish body.

Finally, some vendors in the market use a variety of fraudulent methods to make the fish's body color redder and more vivid, including laser coloring, surface dyeing with pigments, and injecting colorants into the fish's muscles. I have personally seen people dye kissing fish into glittering red, green, blue and other colors, which look very good, but these "artificially beautified" fish are often weak and generally difficult to survive after being bought back.
