Anchovies are commonly known as "Zi'an" and their scientific name is "Phoenix". They are rare economic fish and a small migratory fish. But how to raise anchovies? The following This is what I organized for you, I hope it is useful to you.

Characteristics of anchovies

Small in size, long and flat on the sides, tapering backwards, rather like a knife. The snout is short and slightly rounded, the mouth is large, lower, the orifice is oblique, the back of the body is light green, the sides and abdomen are silvery white, the body is covered with large and thin round scales, there is no lateral line, and the 6 rays in front of the pectoral fin are extended and free It is filamentous, with a large anal fin and is connected to the tail fin.

Chongming anchovies have delicate meat and rich nutrition. Braised anchovies have an attractive color and tender meat, which doubles your appetite; fried anchovies are charred on the outside and soft on the inside, crispy and delicious, making them a delicious treat at banquets; canned anchovies are exported and are highly favored, with demand exceeding supply. String anchovies one by one and dry them in the sun to preserve them for a long time. Steamed dried anchovies are fragrant, delicious and can whet your appetite.

This fish has a slender body, flat back and sides, and a very beautiful tail. The size and color of the male and female fish are quite different. The male fish has a thin body, 4 to 5 cm in length. The dorsal fin is long and pointed, the caudal fin is wide and long, accounting for more than half of the total length, and the caudal fin is long and larger than the height of the caudal fin. According to the shape of its tail fin, it is divided into early tail, lower sword tail, double sword tail, fiddle tail, needle tail, round tail, flag tail, fan tail, triangle tail, scissor tail, pointed tail, large tail and other varieties. . The colors of its body, dorsal fin, and tail fin are colorful, mainly including red, blue, black, yellow, green, tiger skin color, and variegated colors. Some male fish have small blue-black spots on their tails, which look like peacock's tail feathers, hence the name. The body of the female fish is thicker: the body length can reach about 7 centimeters. The body color is dull, flesh-colored, and slightly transparent. The color of the dorsal fin and tail fin is much inferior to that of the male fish.

Guppies are the most common and most common tropical fish. The most popular fish that people keep. It is small and exquisite, lively and active. The male fish is about 4 to 5 cm long, and its caudal peduncle and caudal fin account for about 2/3 of the body length; the female fish can reach 6 cm in length, and its caudal peduncle and caudal fin account for 1/3 of the body length. /2 or more. The body color of male fish is colorful, including red, orange, green, green, blue, purple and other colors. The basic colors are light red, light green, light yellow, red, purple and peacock blue. There are blue-red round spots on the tail fin and body belly, and there are light rings around them, which resemble the color of peacock tail feathers, hence its name.

The body color of female fish is much inferior to that of male fish. Most of them are single silver-grey. Although there are some patterns on the tail fin, they are not as bright as the male fish. The fins of the female are shorter than those of the male, but the body length is about twice that of the male.

Anchovy feeding techniques

Appropriate water temperature is required

The acceptable water temperature for guppies is from 18℃ to 34℃. It is easier if it is lower than 18℃ Some conditions occur, such as loss of appetite, mental weakness, and easy infection by water mold and other diseases. Therefore, it depends on personal circumstances to decide whether to use a warmer.

Appropriate pH value in water

The most suitable pH value for guppies is between PH6.5 and PH7.5. The pH value of water has a great impact on guppies. , the pH value is in logarithmic form, so water with PH5 is ten times that of PH6 and a hundred times that of PH7. Therefore, for humans, the difference is only a small "1", but for guppies, it may be almost tortured. dead.

Another thing to note is that if the breeder changes the water less often, the water quality will have turned acidic due to various factors over time. If a large amount of water is suddenly changed at this time, it will inevitably cause a considerable impact on the guppy.

Appropriate hardness in water

Guppies like hard water, with a hardness of about 10 to 15 degrees. Even so, in the personal opinion of the moderator, the hardness of water is not good for guppies. It won't have much impact. Let's take two countries with a long history of raising peacocks: Germany and Japan as examples. The water in Germany is hard water, while the water quality in Japan is soft water. These two completely different conditions Peacocks can be raised well. It can be seen that peacocks are very adaptable and do not need owners to bother adjusting the hardness of water. This is one of the reasons why many people often say that guppies are easy to keep.

Appropriate nitrite concentration in water

The level of nitrite concentration also has a considerable impact on the survival of guppies, although peacocks are far more adaptable to nitrite concentrations than other fish species ***According to data, the nitrite concentration that guppies can tolerate is about 100 times that of the colorful fairy*** But once the nitrite concentration is too high, it is always a harm to the peacock, especially if the aquarium is a completely closed one Water bodies, and we usually raise fish at too high a density, so if we are negligent, the guppies may die collectively in a short period of time. As fish owners, aquarists cannot ignore the importance of this issue. The market There are many reagents for testing nitrite concentration sold online, and the approximate value can be easily measured.

To solve the problem of excessive nitrite concentration, the fastest way is to immediately replace it with fresh water without chlorine. However, if the nitrite concentration is too high for a long time, you must consider whether the filter is too effective. Poor or the fish stocking density is too high.

Use of feed

Artificial feed:

There are many types of artificial feed currently on the market, which can be roughly divided into three types: 1. Flake feed; 2. Pellets feed; 3. Frozen feed. These feeds are among the easiest to obtain and feed. In addition, there are feeds specially developed for guppies, which should be the staple food of most guppy owners. The nutritional content is also quite complete.

Live bait:

The use of live bait has always had mixed reputations, because the nutritional value of live bait is of course far better than artificially processed feed, but it comes with It is a matter of safety. As owners, we must not be careful, otherwise the sequelae will make you feel that it is better to just feed feed!

The safest live bait at present is brine shrimp. ***Nauseum larvae***! The preparation time does not need to be too long, and it does not require too many procedures. However, after hatching, you should feed it as soon as possible, because the most nutritious thing about the nauplius larvae is that they are still with you just after they hatch. During the yolk sac growth process, if the time is delayed for too long, the yolk will have been absorbed by the nauplii larvae, so the nutritional value will be slightly compromised. If netizens have the habit of hatching brine shrimp to feed peacocks, and if there are more than one hatched brine shrimp, they can be frozen. When feeding next time, they can be used as long as they are thawed. Live bait such as silk earthworms and water fleas can also be fed.

Notes

Guppies are easy to die in spring and autumn. This is because the temperature changes greatly in spring and autumn, and fish are relatively easy to get diseases, especially common diseases such as white spot disease and saprolegnia.< /p>

Some of the most commonly used live baits in aquariums are silk earthworms. The nutritional value of silk earthworms is very high. If you put some in the fish tank, they can survive for a long time and keep your peacocks eating. Therefore, guppies It will grow very quickly and can be used as a medicinal bait. Feed the medicine to the silk earthworms first to turn it into a medicine bait, and then feed it to the guppies. The effect is quite good. From this point of view, silk earthworms should be the most perfect feed. However, since silk earthworms are collected from the wild, although some aquariums will sterilize them first, there is no way to guarantee that silk earthworms will not contain bacteria in their bodies. There are parasite eggs, so users have to be careful.

Water fleas can be reproduced in green water. It should be noted that water fleas that have just been collected from the wild are best not to be fed directly to fish, because water fleas are the intermediate hosts of camel-shaped nematodes. Being parasitized by camel nematodes cannot be solved with just a few words! Moreover, the water fleas collected in the wild may have a high bacterial load in the water in the wild. If they enter the fish tank rashly, they may infect the little treasure in the greenhouse - the peacock. fish. Also, pay attention to which type of water flea you get. If it is a water flea, it is not suitable because of its hard shell.

Anchovies are a type of tropical fish that is relatively easy to raise. They do not have high requirements for water quality and temperature, and their adaptability is very strong. They can survive when the water temperature is above 18 degrees, and they do not need to be heated throughout the winter. , just don’t like to swim very much, but when changing the water, you should pay attention to the temperature of the new water and the old water to be consistent. This kind of fish is small in size and has a gentle temperament. It is best not to mix it with other species of fish.

The value of anchovies

Modern scientific research shows that anchovies contain protein, fat, carbohydrates, calcium, phosphorus, iron and trace elements zinc, selenium, etc. Trace elements such as zinc and selenium are beneficial to children’s intellectual development.

It has also been found to promote the increase of infection-fighting lymphocytes in human blood. It has also been clinically proven that anchovies are beneficial in improving the body's tolerance to chemotherapy. The tail fish is delicious and can be eaten fresh, dried, fried or canned. Canned food made from anchovies has always been one of the important export products of the food industry and sells well both at home and abroad. Canned anchovies must be made with eggs

Female fish *** commonly known as "grilled fish" by Shanghainese ***. The processing and production procedures require very fine details. Clean the fish first, then proceed with frying, seasoning, dipping and other processes. After the anchovies are made, they have a bright yellow color, a crispy outer layer, tender meat, few tender bones, a slightly salty and slightly sweet taste, and a delicious taste. ?
