Can baby goldfish be artificially egged in winter?

First of all, you see if he ovulates or not, like a male chasing a female.

It can usually be isolated into a separate pot to lay eggs naturally.

Newcomers are generally not recommended to squeeze eggs by hand, which is easy to hurt the fish.

Goldfish will be rear-ended when mating, 1. Store a sufficient amount of water in case of water change.

2. Prepare two other containers, one for mating and spawning, and the other for hatching.

3. Make a fish nest for spawning, or spread a layer of brown flakes on the bottom of the mating spawning container (be sure to boil thoroughly, disinfect and wash).

4. After changing into the new water, seeing that the goldfish are not stopping, the goldfish that are chasing each other can be fished into the mating spawning container, and the water in the container must be stored or sun-dried for three days and isothermal with the old water.

5. After spawning, gently take out the fish nest or brown flakes full of fish roe and put them into the incubation container for incubation, and the goldfish will be fished out and still put back in the old fish tank for feeding. (The water in the spawning tank is very spoiled, and the goldfish and fish roe are fished out, and the water is not needed.) ）

6. Do not move the hatching container often, so as not to affect the hatching rate and produce deformed small fish.

Normally, goldfish only spawn once a year, and after they spawn, it takes a year for them to start spawning a second time. There are also some goldfish, which can spawn 1-3 times a year, but this is less common, early and the time between them is not fixed. In addition, some goldfish may not be able to spawn in one day, so they will continue to produce the next day.

Most goldfish start spawning in the early hours of the morning, while some spawn at night.

Goldfish spawn for the first time and then lay again every few days, how to deal with it after spawning.

1. Goldfish spawn for the first time and then give birth every few days.

Goldfish spawn infrequently, they can only spawn once a year, so the second spawning takes a year apart. Of course, this is only the majority of goldfish, but there are also a small number of goldfish that can spawn 1-3 times a year. However, this is not very common, and the intervals of the year are not fixed.

There are also some goldfish that cannot spawn in one day, so they will spawn for 2 days in a row, and some will produce intermittently. Goldfish production is mostly from 4 a.m. to 10 a.m., but some start in the evening.

2. How to deal with goldfish after spawning.

1. Fish eggs: If the eggs produced by goldfish have been fertilized, the keeper needs to transfer the eggs to a separate container for incubation. When incubating, the water temperature should be kept at about 25, so that they will hatch faster, and they can hatch successfully in about 2-3 days.

If the goldfish spawns without the male fertilization, then the eggs cannot become fertilized eggs, let alone hatch small fish. Keepers can directly fish out the eggs and throw them away, or they can let the broodstock eat the eggs directly.

2. Broodstock: Goldfish need to be isolated immediately after giving birth to prevent them from eating the fertilized eggs as food. In addition, the keeper should also feed them more high-nutrient food, which will help them recover quickly.

After a few days of recovery, they can be put back in the tank.

Answer: When you dress up as a male fish, you will be fertilized. There is an aura to the spawning of goldfish:

A seasonal temperature is generally in the spring of each year, when the temperature reaches more than 16 degrees, but it is better to lay eggs around 20 degrees. In autumn, when the temperature is scarce, it will also lay eggs. 2. Weather Time Mornings after rainy or foggy days tend to give birth to wide eggs.

The time generally starts early in the morning and lasts until around 9 a.m.

Under normal circumstances, goldfish spawn in March to July, and generally 1-3 times a year.

Under normal circumstances, goldfish spawn between March and July, and usually spawn 1-3 times a year.

1. Generally, 3-7 days after spawning, fish larvae appear; It takes about 7 days for goldfish to appear after spawning.

2. When the average water temperature is 15-20, the number of days of incubation is 5-7 days; When the average water temperature is 20, small fish can hatch in 4-5 days.

3. When the average water temperature is 20-25, it only takes 2-3 days. In general, the lower the water temperature, the longer the incubation time.

4. If the fish in the fish tank is sure to have spawned, it has been a week, and no small fish have appeared. In general, there are the following situations.

1) If the water temperature is too low, the incubation time will be extended.

2) The eggs have not deteriorated and whitened, and the whitish eggs indicate that they have died.

3) If there is no male fish but only the larvae under the female, there will be no hatchling.

After the goldfish hatches the eggs, the temperature of the water should be kept at 18 22 degrees, and it doesn't hurt to be slightly higher.

DAO can distinguish that the translucent fish eggs are the response eggs, which can hatch the baby, while the other white or even hairy ones have no life factors, and the living part can hatch the baby fry after 3 or 4 days. After a long time, there are still no small fish, and it is indeed because the eggs are not fertilized.

When the juvenile reaches 1 cm in length, it is already very clever and not easy to be swallowed, so it can be put together at this time.

How to raise fry.

Step Method.

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.

Hatching methods for harvest shrimp and harvest shrimp.

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.

Just wait until the goldfish grows to one-quarter of the size of a large goldfish.
