Culture techniques of black prawns

Black prawn generally refers to the black crystal shrimp, if the crystal shrimp is the aristocracy of the shrimp, then the black prawn is the aristocracy of the crystal shrimp. Let's take a look at how aristocrats are raised.

Culture techniques of black prawns

First, equipment: all the mute equipment used, of course, domestic products are not in the field of vision, the basic consideration is the Ehan and Japanese HIBLOW brands.

Second, dissolved oxygen equipment: water leprechaun + dissolved oxygen with a combination of water leprechaun and dissolved oxygen, as crystal shrimp has a great demand for oxygen, so I will consider more in this regard, and the configuration of the air pump will also be relatively powerful. The water demon is basically Japanese, such as the tooto brand, and dissolved oxygen also chooses tooto, this brand not only works well but also looks good. The basic configuration of the fish tank, of course, is crystal glass, but I recently found that ultra-white can still replace the so-called crystal glass on the market, and the price is much cheaper, friends might as well study it.

Third, filtration system: in addition to a group of external filter buckets for external use, the new cylinder currently opened by the bottom filter has not been considered, because several books have to reverse the cylinder in 6 months, so it has been abandoned. If you need not reverse the cylinder for a long time, you can still consider the combination of thickening the bottom mud and increasing the bottom filter. The effect is still good. The filter bucket is mainly economic (can't you see it in the cabinet) plus mute? So the domestic at-3338 entered my choice, and the performance-to-price ratio is good over the years.

IV. Bottom bed

The bottom bed is the best environment for the root development of aquatic plants, and there are many kinds of bottom bed, mainly with stones (silica sand) and soil (black soil) as the main medium. When the aquaculture tank is cultivated for a period of time, some fish and shrimp excreta or other microbial metabolites often accumulate in the bottom bed, and the black soil will disintegrate into debris or debris over a long time, which will often lead to the accumulation of impurities in the bottom bed and gradually harden into poor permeability of the bottom bed, which will affect the development of the roots of water plants.

Five. aquatic plants, sunken wood and other equipment

Mousse is the most commonly used species of aquatic plants in crystal shrimp tanks. The growth conditions are very low and do not need to be taken care of. Tie it to the sunken head and use it. It helps the shrimp to hide, especially when the shrimp is in the most vulnerable period after braising. And shrimps also like to gnaw on some algae that grow on sunken wood. Therefore, close planting of aquatic plants and putting in a large amount of sunken wood is the best way. If you want to put in some stone furnishings, as long as it will not affect the water quality.

VI. Feed for crystal shrimp

Feed is the substance that provides nutrition to shrimp, so no matter whether the shrimp food purchased is expensive or not, first of all, it depends on whether it is nutritious, nutrition is the key. Mulberry leaves choose pesticide-free ones. For ordinary players, I suggest that it is also possible to choose two kinds of shrimp food with their own spinach. The good thing about shrimp food is that shrimp food is thrown into the jar and shrimp will soon come to eat. This is good shrimp food. Nutritious shrimp food can provide nutritious substances to shrimp.

The source of black prawns

Black King Kong is a mutant obtained from the mating of ordinary black-and-white crystal shrimp with golden shrimp pedigree. This time, a case of black King Kong adult shrimp has been reported in southern Taiwan. This is great news for friends who continue to pay attention to the development of strange shrimp and like crystal shrimp. The destination of our trip is the Yicheng Shui breeding Farm in Daliao Township, Kaohsiung County. Mr. Wu Yulin, the owner of the fish farm, is the protagonist of creating stable Black King Kong individuals. Usually, he likes to study the mating and genetic changes of ornamental fish, and launch new species from time to time. At present, he runs the fish farm with his sister Mrs. Zhong, and the main breeding species include small Galaxin, South American sea bream, general fish and crystal shrimp.

Because the black gene has not yet been fully constructed, the number of individuals with all black body color, commonly known as black King Kong, is very rare. More than 90% of the offspring are still ordinary shrimp with black and white body color. Only a small number of individuals' white body color is slightly stained with a layer of blue and black, which is quite special.

The special price of black prawns

A pair of mutant "Black King Kong Crystal Shrimp" about two centimeters long costs NT $270000, but its general "siblings of the same clan" sell for only NT $50 to NT $100 in the aquarium. Taiwan's ornamental fish are worth about 100 million yuan a year, and internationally favored "aquarium stars" such as black diamond crystal shrimp have created another Taiwanese miracle.

Taiwan's first "Taiwan ornamental Fish Expo," which focuses entirely on ornamental fish, opened on Friday, displaying nearly 150 tanks and more than 200 species of ornamental fish, of which the most selling point is black diamond crystal shrimp. The world's largest "golden blood parrot", which is 30 centimeters long, and artificially bred clown fish and fluorescent fish are also the focus of magnesium lights.

Black King Kong Crystal Shrimp won the championship in the German International Shrimp Competition and the popularity Award for Public Voting this year. The "Taiwan ornamental Fish Expo" will be on display at the World Trade Center in Taipei from Friday to next Monday.

Sha Zhiyi, director of the Fisheries Department of the Taiwan Council of Agriculture, said that in the past four years, Taiwan has invested about 2.5 billion yuan in the development of the ornamental fish industry. due to suitable climatic and geographical conditions, as well as technological advantages, new species have emerged every year, not only the fish itself. the surrounding fish tanks, landscaping and other related industries have also benefited; the Council of Agriculture has included ornamental fish in the key industries of the "refined Agricultural Health Excellence Program."

Disease prevention and control techniques of black prawn

Molting is the most common disease of crystal shrimp. The symptoms are as follows:

A, not completely desquamate. After molting, the shell is still connected to the body, which is due to lack of calcium. Therefore, it is necessary to add various minerals regularly to maintain the stability of the total hardness in the water.

B, death occurs immediately after peeling, usually in the hot summer. Due to the addition of a large number of fungicides in tap water, the body surface of crystal shrimp does not have any protection after peeling, and its resistance to the outside world becomes weak. Therefore, when changing the water, it should be treated in advance to make the water quality as close as possible to the water quality in the aquarium.

Do you find it difficult to raise such expensive shrimp? as long as there is a good environment and good breeding, it is relatively easy to feed. Black prawn has a good physique, a large number of offspring and a high survival rate because of its stable genes.
