How to raise anchovies
1, should have the appropriate water temperature.
The acceptable water temperature of anchovies ranges from 18℃ to 34℃. If it is lower than 18℃, some conditions are likely to occur, such as loss of appetite, mental paralysis, and water mold infection, so it is necessary to decide whether to use the heater according to personal conditions.
2. Appropriate PH value in water
The most suitable PH value for anchovies is between PH6.5 and PH7.5. The pH value in water has a great influence on guppies. The pH value is logarithmic, so the water with PH5 is ten times as high as pH 6 and one hundred times as high as pH 7. Therefore, it is only a small gap of 1 for humans, and I am afraid that anchovies have been tortured to death.
In addition, it should be noted that if the breeder changes the water less frequently, the water quality has already turned acidic due to various factors over time. At this time, if the water is changed suddenly in large quantities, it will inevitably cause considerable impact on anchovies.
3. Proper hardness in water
Anchovies like hard water, and the hardness is about10 ~15 degrees. However, the hardness of water will not have much influence on guppies. Take Germany and Japan, two countries with a long history of raising anchovies, for example. The water in Germany is hard, while the water quality in Japan is soft, and these two completely different conditions can make anchovies. This is one of the reasons why many people often say that anchovies are easy to raise.
4. Appropriate concentration of nitrite in water
The concentration of nitrous acid also has a considerable impact on the survival of anchovies. Although anchovies are far more adaptable to the concentration of nitrous acid than other fish species, once the concentration of nitrous acid is too high, it is also a kind of harm to anchovies, especially the aquarium is a completely closed water body, and we usually raise fish at too high a density, so once we are careless, anchovies may die suddenly in a short time. We can't ignore the importance of this problem. There are many reagents for testing the concentration of nitrite on the market, which can easily measure the approximate value.
To solve the problem of high nitrite concentration, the quickest way is to immediately replace it with fresh water with chlorine removed. However, if the nitrite concentration is too high for a long time, it is necessary to consider whether the filter effect is too poor or the fish feeding density is too high.
5. Use of anchovy feed
Artificial feed:
At present, there are quite a few kinds of artificial feed sold in the market, which can be roughly divided into three types: first, flake feed; Second, pellet feed; Third, frozen feed. These feeds are the easiest to obtain and feed. In addition, there are feeds specially developed for anchovies, which should also be the choice of most anchovies owners as staple foods, and the nutritional components are quite complete.
Live bait:
The use of live bait has always been mixed, because the nutritional value of live bait is far better than that of artificially treated feed, but it is accompanied by safety problems. We must not be careless, otherwise the sequelae will make you feel that it is better to feed only!
At present, the safest live bait should be shrimp (nauplii). It doesn't take too long to prepare, and it doesn't need too many procedures. However, after hatching, it should be fed as soon as possible, because the most nutritious thing for nauplii is that when they just hatch with yolk sac, if the time is too long, the yolk has been absorbed by nauplii, so the nutritional value will be slightly discounted. If you have the habit of hatching prawns to feed anchovies, you can freeze them if you have more hatched prawns, and you can use them when you feed them next time as long as they are thawed. You can also feed live bait such as earthworm and Daphnia.
Matters needing attention in anchovy culture
1, anchovies are easy to die in spring and autumn, because the temperature changes greatly in spring and autumn, and fish are relatively easy to get sick, especially common diseases such as white spot disease and water mold. So in these two seasons, we should pay more attention to anchovies.
2. The longest live bait used in some aquariums is the silk earthworm, which has a very high nutritional value. If you put some in a fish tank, it can survive for a long time, so that your anchovies can keep eating, so the anchovies will grow quite rapidly, and it can also be used as a drug bait. The drug is first fed to the silk earthworm to become a drug guide, and then fed to the anchovies, and the effect is quite good. In this way, the earthworm should be the most perfect feed, but because the source of the earthworm is collected from the wild, although some aquariums will sterilize it first, no one can guarantee that the earthworm will not carry parasitic eggs in its body, so users have to pay attention.
3, Daphnia, can be propagated with green water, it should be noted that Daphnia just collected from the wild is best not to feed the fish directly, because Daphnia is the intermediate host of camel nematodes, once it is parasitic by camel nematodes, it can not be easily solved! Moreover, Daphnia collected in the wild may have a high bacterial content in the wild water, and if it rashly enters the fish tank, it may infect the anchovies in the greenhouse. Also, pay attention to what kind of Daphnia you get. If it belongs to cyclops, it is not suitable because of its hard shell.
4. Anchovy is a kind of tropical fish that is relatively easy to raise. It has low requirements on water quality and temperature, and is very adaptable. When the water temperature is above 18 degrees, it can survive completely. It doesn't need to be heated all winter, but it just doesn't like swimming. However, when changing water, it is necessary to keep the temperature of new water and old water consistent. This fish is small in size and gentle in temperament, so it is best not to mix with other kinds of fish.
