Colored fish refers to the combination of a certain kind of fish and another kind of fish through artificial genetic modification technology, so that the body of the fish changes color and shape, so as to achieve the appreciation value. To determine what is genetically modified fish and dyed fish, in fact, very good to determine, there are mainly these two ways.

I. Dyeing fish determination method

Colorful fish generally exist in certain places such as vegetable markets or parks, life is basically everywhere. But in the face of huge benefits, some fishmongers, will use dyed fish as rare color fish to sell, so as to deceive consumers. If you buy food in the market, very worried about whether the colorful fish in front of you is dyed fish, you can determine this way. first dyed colored fish in the fishmonger side, usually put a special dye bags or barrels, and the other side of the place, is already coated with dye fish. This dye, which is easily diluted off with water, is commonly dyed with potassium permanganate and carmine red. If you find a fishmonger with such tools or fish around you, don't ask for more, but turn around and walk away to avoid unnecessary trouble. The second way to determine is through the color, dyed fish, the fins will be yellowish especially obvious, and very unnatural, colored fish and normal fins at the same. In addition, dyed fish, fish eyes will become yellow, while no color fish, eyes are black and white that kind of clear. These are two ways to determine whether a colored fish is a dyed fish.

Second, genetically modified fish determination method

In fact, there is no large-scale genetically modified fish for sale on the market. Because of the genetically modified fish, the survival rate is very low, it is not like ordinary fish, you can do to survive for one or two years or even longer. We can hear the word genetically modified, usually only in food, such as soybeans and corn. According to my information, colorful genetically modified fish in China, basically very difficult to see, the so-called genetically modified fish on the market, most of the so-called genetically modified fish, most of the artificial cultivation of cross-breeding and breeding, such as the red carp in the park, the golden grass carp, the silver trout, and so on, are all artificial cultivation of cross-breeding and coming. Because the reproduction ability of fish is originally very strong, people if the fish genetic intervention, then it will cause the fish extinction and so on, so the market color fish, not necessarily all are genetically modified fish. In life, we do not have to worry about whether there are colorful genetically modified fish, more to learn to identify dyed fish, because dyed fish on the human body is the greatest danger, so we must learn to identify.

three, color fish have which fish

Color fish, we live in a very common, when you walk into some large parks or aquariums, as long as the discovery of colorful fish inside, these are basically a variety of color fish. More well-known colorful fish are colorful fish, parrot fish , peacock fish, kissing fish and parrot fish and so on. They are named, for the most part, after the shape of the fish. Colorful fish like parrot fish are usually more common in the aquarium at home, it is reddish all over and its mouth looks like a parrot, it is very popular among people. Personally, I also like the parrot fish this whole body with colorful fish, buy one at home to keep, is also a beautiful scenery. If you also like colorful fish, then you may want to prepare a water tank, raise their own to enjoy watching it.

The above is about the colorful fish is genetically modified or dyed fish determination method, I hope to help you.
