How to feed the newly born small fry and how to feed the small fry

The feeding method for newborn small fry is:Newborn fry do not need to be fed on the first day, and it does not have a yolk sac to absorb.

Usually wait a day before feeding.

You can't choose fish food for feeding the fry, its mouth is too small, and you can't feed the fish food, it is best to feed plankton, you can find a little water, and if you don't have it, feed cooked egg yolk or soy milk.

It should be noted that the amount of cooked egg yolk must be controlled, and it can be wrapped in gauze and twisted a little each time.

When the fry can swim to the surface, start feeding the lice. Water lice are fish insects that are fished in.

Worms filtered out through gauze or plastic mesh. When it grows to a centimeter or two long, it can be fed to ordinary fish insects.

Frozen harvest shrimp.

After thawing, it is slightly crushed and fed.

Artificial dry bait is slightly ground and fed.

Dried bloodworms are ground and then fed.

First of all, a constant water temperature is the key to the healthy growth of small fish. Whether it is in the growth stage, the disease stage, or the new fish fry stage, the water temperature highlights its importance all the time. For fish fry, water temperature is a life-threatening matter.

For adult fish, the water temperature generally only needs to be controlled within a certain range, and the fish can grow healthily; For fry, even a difference of 1-2 can have a drastic effect.

According to the usual experience, it is generally most suitable for the growth of small fry by slowly increasing the temperature of the suitable water temperature for adults by 1 -2. Take our most common ** Dafan as an example: the suitable temperature for adults is 24 -25, and the suitable temperature for fry is 26 -27.

At this temperature, the mustache feels warm, the frequency of activity increases, the appetite becomes better, and the growth rate is accelerated. The change of water temperature is one of the important factors leading to the sudden death of small fry. Especially when changing the water in the aquarium, be sure to pay extra attention.

Small fry are weak, and as long as the water temperature is more than 2 different, they will get sick or die because they cannot adapt.

The second is water quality, and the requirements for water quality for fish fry are higher than those for adult fish. If the water quality is not good, it can lead to an increase in the growth rate of other microorganisms and the fry will be infestation by germs. Treating small fry is a very troublesome task, and if the dose is not properly grasped, it can be counterproductive.

Therefore, the most important thing is to start at the source and eliminate water quality problems that can lead to infection.

Then there is the bait, and in the first few hours of birth, the fry begin to show a craving for food, and even swim around in search of food. At this time, you can choose to feed the larvae of the shrimp larvae to the small fry in an appropriate amount. Shrimp larvae have high nutritional value and are healthy and hygienic, which can help small fry grow quickly.

If there are no abundant shrimp larvae for the time being, only adult fish feed, they must also be crushed into powder for feeding. The principle of feeding small fry is to feed small and frequent meals, and never feed too much at once. For small fry, egg yolk is a very nutritious food, but if you are a novice fish farmer, it is best not to use egg yolk, because fish fry are very sensitive to the consumption of egg yolk, and it is difficult for novices to control the amount of feeding, once fed too much, it is easy to pollute the water quality.

The yolk that is not filtered out will decompose and deteriorate in the fish tank, causing damage to the water quality and causing the fish to die.

Finally, it is put back into the large tank, and one month after the birth of the small fry, the fish should be released from the breeding box and put back into the fish tank, so as not to have too little space in the breeding box and the fish will fight and be injured. Of course, if there are conditions, it is better to open a separate tank and raise a nest of seedlings, or raise the seedlings within half a month, because the individual difference is too great, there will be a situation of grabbing food, and even big fish biting small fish.

Egg yolks. To cook, take a small piece and wrap it with fine gauze (a dense-eyed fishing net can also be used), wet it on the water surface, and then gently pinch it with your hand on the outside of the fishing net, and the egg yolk will break, and then gently shake the gauze on the water surface a few times, so that the broken egg yolk will scatter into the water, and the small fry will start to eat when they see it. Don't do too much at a time, the fry may not be eaten after sinking to the bottom, which will affect the water quality.

This method is suitable for feeding ovoviviparous fish such as guppies, red arrows, pandas, Marys, etc.

Feeding. Turbulent water is actually water rich in paramecium or rotifers, and such water needs to be cultivated by ourselves, so I won't talk about it here. This method is suitable for feeding small oviparous fish, such as angelfish, lantern fish.

Harvest shrimp. Harvest shrimp can buy harvest shrimp eggs to hatch by themselves, or they can be directly fed to the shelled harvest shrimp eggs (the particle size is very small, and many fry can be eaten directly, which is convenient and clean). After hatching, the shrimp can be fed immediately, and over time, they will grow into large individual shrimp, and they can be fed with slightly larger fry.

This method is suitable for feeding a variety of fish, with high nutritional value, convenience, cleanliness and is not affected by the season.

The larvae of the daphnia.

That is, buy small fish and insects (cladopods, scratch feet) from the market, and put them in water basins, small jars, pet boxes, and wide-mouth containers are the best, because Daphnia will swim to a place with high oxygen content near the water surface to breathe, and if the mouth is small, it may cause suffocation and death. This allows us to harvest new white larvae from the surface overnight and feed them directly to the fry. If you want to keep it for a long time, you can add a small amount of nutrient solution (yeast powder) to the container, put it in a bright place, and change some water appropriately, so that you can provide food for small fry for a long time.

This method is suitable for feeding ovoviviparous fish such as guppies, red arrows, Marys, etc.

Rolling feed. The small pellets (small and nutritious are selected), crushed into foam with a hard card, and then sprinkled directly on the water surface to feed the small fry. This method is suitable for feeding fry over 1 cm.

If the small fry are fed, they only need to be fed well, and then the fry are fed, and the fish are fed and added to the water. Domestic.

The answer is mainly to feed pellet feed, the protein content of the feed is 28 32%, supplemented by green feed. Feed feeding follows the principle of "coarse before fine" and "four fixed and four looks", generally fed twice a day, to eat within 2 hours, grass carp 8 into full is appropriate. After continuous feeding of pellet feed for a period of time, the pellet feed should be stopped for 1 week, and the raw grain feed should be fed during the interval period.

Usually pay attention to adding vitamins and other drugs to the feed to avoid grass carp suffering from hepatobiliary syndrome and other diseases and causing a large number of deaths.

If you are a good friend how to feed the small fry, you must first have a good environment, so that it will grow better and faster.

Small fry, how to feed? Small fry should not be fed with adult fish. It is best to keep it alone.

The mortality rate of wild small fry is extremely high, but if it is a pet fry artificially raised in a fish tank, as long as the environment and food are controlled, the probability of death can be greatly reduced, and the small fry can grow faster and better. As for what to feed the small fry, it is best to feed them special fry feed, so that the nutrition is more comprehensive and can also make the fry grow faster.

1. Fish fry feed

Now the development of fishery and aquaculture industry is relatively good, the family pet fish are also very much, the newborn small fry are naturally not afraid of no special supporting food supply, you can go to a special store and ** to buy fry feed, feeding is convenient and worry-free, generally small fry will eat.

2. Boil the egg yolk

If there is no feed prepared for the fry at home, you can cook the eggs in white water, then take out the yolk to cool, then crush it and wrap it in gauze, and then put the gauze wrapped with the egg yolk into the fish tank and swing it gently, so that the egg yolk fragments seep out, and you can also give it to small fry to eat, but you can't put too much egg yolk at a time to avoid polluting the water quality, enough for small fry to eat, you can eat a small amount of many times.

3. Harvest shrimp

If you want small fry to grow faster, you can also feed them harvest shrimp, but even harvest shrimp will be more expensive, and it is a little troublesome to feed. And the fry that are too small can't eat the shrimp, so you need to wait for the fry to grow up a little more, so that the fry can grow more rapidly.

4. Nematodes

If the fry are too small to eat, you can chop the nematodes and then feed, you can feed them about three times a day, and the small fry can't eat too much at one time, so feed less each time, so as not to sink the food to the bottom of the tank and pollute the water quality.

5. Fish insects

After the small fry grow for a period of time, they can swim to the surface of the water, at this time they can feed the fish insects, the fish insects are also called water lice, the newborn fish fry can not eat, but also need to grow a little bigger and then feed, some fish and insects are relatively large, you need to use a filter to screen it, so as not to eat the fish fry.

6. Drainage

If you are patient, you can make a water feed for the fry, which can make the fry grow faster. The water is rich in paramecium's white turbid water, you can fish some in the pond in the spring, or you can do it yourself, cut the straw and boil it in water for ten minutes, add a little water to the sun for a week after cooling, and then you can fish out half of it and feed the fry, and the remaining half will continue to cultivate.

When feeding the fry, we must pay attention to the balance of nutrition, pay attention to the ratio of various nutrients, and the fry can grow well and fast after eating. Change the water regularly, clean the tank, maintain a good ecological environment, and avoid the death of fish fry.

At the beginning, it is best to raise large fish in separate tanks, because some big fish may eat small fish, generally wait until the small fry grow up, and the big fish can not eat and then mix the small fish and the big fish together.

The method of raising small fry is as follows:

Juveniles are easy to raise, as long as the temperature, water quality, feed well, and keep the tank clean.

1. Temperature requirements:

Juvenile fish should not change their temperature by more than 1, so the tank where juvenile fish are kept should be placed in a place with a high and stable temperature.

2. Water quality requirements:

Juvenile fish are also sensitive to water quality, and when the quality of the water they put in is very different from the quality of the raw water, it is likely that the small fish will die. Don't change the water too often for juveniles.

3. Feeding requirements:

Juvenile fish can eat paramecium, shrimp, earthworms, crushed cooked egg yolks, solid pellet feed, etc. If you are feeding egg yolks, you can crush them and wrap them in gauze, and shake them in the fish tank when feeding. You can also use a small portion to put it in the water.

When feeding solid feed, you can grind it and put it in water, and the feed will be soaked softly, and the small fish can eat it.

4. Keep the cylinder clean

The leftover residues should be cleaned up in time to avoid water deterioration due to high temperatures in summer.

It is also called "fish flower". Newly hatched juveniles, generally 6 9 mm long. There are artificially bred fry and natural fry from rivers.

In order to ensure the survival rate of the fry, it is often necessary to provide palatable, rich and nutritious open bait in the early stage of culture. Several kinds of open baits are commonly used in the process of seed cultivation and are egg yolk, soybean milk, rotifers, algae and aquatic microecological preparations.

You can wrap the hard-boiled egg yolk in fine gauze, twist it lightly with your hands in water and shake it slightly, so that the egg yolk slowly oozes out for the fry to eat. Pay attention to twice a day, and the amount should be small so as not to pollute the water quality and cause the death of small fry. Of course, there are other ways to feed small fish, starting to feed small fish insects (water lice) when the fry can swim to the surface.

Small fish worms are small worms that are filtered out of fish insects that are fished out with gauze or plastic mesh sieves. When it grows to a centimeter or two long, it can be fed to ordinary fish insects. It can also be frozen, slightly ground after thawing, and then fed. In addition, you can also feed artificial dry bait or dried bloodworms after a little grinding.

Eat plankton or powdered fish food. But the first concern is not what it eats, but to separate it from the broodstock as soon as possible, because a considerable part of the ornamental fish will eat the juveniles for various reasons. Newly hatched harvest shrimp Daphnia If you don't have it, it's egg yolk water, but not too much bad water, isolating small fish is necessary, and you need to use the original tank water, and the temperature fluctuation can not be large.

Don't copy the net, speak with experience·· It's best to get the Harvest Shrimp · Basically, in addition to the juvenile fish of the climbing family (betta fish, manlong, etc.), other newly born small fish can be opened with harvest shrimp... Juveniles of the family Climbing are generally opened by microworms· If you don't have to make it so troublesome or if the cost is too high, you can use egg yolk instead... However, the bad thing about egg yolk is that it is easy to get dirty water
