Tattoo Machine is a hand-held device generally used to create a tattoo, a permanent marking of the skin
with indelible ink. Modern tattoo machines use electromagnetic coils to move an armature bar up and down,
Connected to said armature bar is a barred needle grouping that pushes ink into the skin. Tattoo artists generally
use the term "machine", or even "iron", to refer to their equipment. The word "gun" is often used but many
tattoo professionals dislike it. Then there are the Tattoo machines which are available at the numerous Tattoo
Supplies stores. These are also known as Tattoo Guns. There is a vast selection of stylish tattoo guns which are
made out of Iron, Copper steel and Top carbon steel and they are designed for lines and shading of the intricate
design on the Tattoo. Then you get the Tattoo Needles of different sizes and shapes enclosed in individual
envelopes.They carry nearly everything a tattoo operation demands or even needs as well at truly competitive prices
for quality items.

1. Check the clear pond effect. Fish seedlings should be used to pull empty ponds for several days in the day before - 2 days before the lower pond, mainly checking whether there are predator creatures in the pond. If wild fish, frog eggs, cockroaches, aquatic insects, and other predators are found, clear the pond. At the same time, the net can also be used to fully dissolve the remaining clear pond drugs accumulated in the bottom of the pool to prevent damage to the fry.
2. Remove residual drugs. If the toxicity of the drug has not completely disappeared, it may lead to poisoning and death of fish in the pond. The inspection method is: 1 Take half a barrel of bottom water, test the fish in the bottom water, or place the fry in a small cage in the pond and observe for 8 hours to 12 hours to determine whether the fry can enter the pool. 2 The pH of the pool water that can be measured by the quick lime pond, such as pH value below 8.5, indicates that the toxicity has disappeared and the fry can be released. 3 Observe the pool water. If there is leeches, it means that the toxicity has disappeared.
3. Pool water test. It is mainly judged by the color, transparency, and food abundance. When the fry were in ponds, the pool water was grayish-white, yellow-green or yellowish, with a transparency of 30 cm--35 cm, with about 10,000 rotifers per litre of water, and a biomass of 20 mg/l - 30 mg/l. If the pool water is not fat enough, the fish will grow poorly due to lack of feed. So the compost should be composted or poured into the pool corner of Xiangyang to fertilize the water immediately. When it is found that the water quality is too fat, it should be diluted with water and then put the fish. For example, if the pond basal fertilizer is too early and the peak of rotifers has passed, excessive zooplankton such as blisters will be generated in the pool water, which will inhibit the reproduction of small zooplankton of the fry, and interfere with the activity and feeding of fry. 0.3ppm--0.5ppm crystal can be used. Trichlorfon is splashed and killed, and fry can be released after 1 day - 2 days, or 300 species of squid with more than 13 centimeters per acre are stocked - 400 large zooplankton are eaten. At the same time, it is also possible to judge whether the pond water is suitable for the fatness of the carp before dawn. However, the carp should be completely caught before the fish is released.
4. Timely pond. Fry hatched for 4 days - 5 days, visible two eye spots, a waist point, in normal swimming in the water, should be promptly over the pond. When entering the pool too early, the fry is too tender and it can easily sink into the sediment and cause death. If it is too late, it will affect the growth of the fry and the survival rate is low.
5. Stocking specifications. The fry stocked in the same pond should be of the same variety and the same specifications, and should be enough to prevent the big fish from suppressing or eating small fishes and the appearance of irregularities.
6. Adjust the water temperature. When fish fry ponds, the temperature difference between the pool water and the fry container must not exceed 3°C. If the temperature difference is too large, it should be gradually adjusted until the fish is adapted to the pond. For fish fry transported in plastic bag, the plastic bag should be opened first and slowly placed into a cage pre-placed in the fish pond. When the water temperature in the pool is the same as the water temperature in the bag, the pool water is gradually mixed with the water in the bag. After 20 minutes, the fry and water are slowly poured into cages to adjust the temperature difference so that the fry can adapt to the air pressure inside the bag. If the fry is directly poured into the pool from the bag, the mortality of the fry is very high.
7. Fry to eat. The fry can be fed with egg yolks before the lower pond and one hen per 100,000 fry. The method is to fully cook the eggs or duck eggs, remove the egg yolk, use double gauze wrapped in the water, knead the egg yolk and splash it on the fry, and feed the yeast or rotifer. Insist on fry feeding satiety pond, its survival rate has increased significantly.
8. Master time, place and method of stocking. Fry stocking should try to choose sunny noon or afternoon, when the water temperature is high, dissolved oxygen is sufficient, is conducive to quickly return to normal activities after the fish pond, should avoid windy windy weather or night into the pool. In the windy days, fry should be put on the top of the deep water, so as not to cause a large number of deaths when the downturned fry is blown to the pool by the storm or to the bottom of the pool. When putting the fry, the container of the fry should be slanted slowly in the water, so that the fry slowly swims out of the water or the seedling container slowly pulls back. Do not pour the fry into the pool. In addition, do not leave the fish fry immediately after entering the pool, and wait until the fry spread into the pool and then leave. If the fish seedlings are found to be densely integrated, they should be splashed with water droplets to spread them into the pool.
9. Pool water depth. Requires pool water to 40 cm - 50 cm depth is good, so easy to increase the temperature of the sun through the sun, adequate light, water quality easy fertilization, fast food biological reproduction, is conducive to rapid growth of fry.
10. The density is suitable. The fry are bred into Wuchi sub-pools, which are generally set acre for 200,000 - 250,000 tails or grass carp, herring, carp seedlings 150,000 - 200,000 tails per mu; if fry bred into summer sub-pools, then each acre鲢 鳙 鳙 鳙 10 -15 -15 -15 -15 -15 -15 -15 -15 -15 。 。 。 。 。 。 。 。 。 。 。 。 。

Fish fry pond management technology
Fish seedlings are one of the key technical aspects to improve the survival rate of fry cultivation. Because of the delicate body, the fry has strict requirements on weather, water temperature, water quality, cleanup of predators, and operations at the time of stocking. The fish farmers will be slightly neglected, and the fry will cause varying degrees of death of the fry, and the entire breeding process will fail. The author summarizes the following points in the management techniques of fish fry ponds for your reference.
