Is it impossible for goldfish to reproduce if it is not cold?

Regarding the problem of most cold-water ornamental fish in the winter high temperature or low temperature feeding, we have to look at it in two, this problem also has a certain relationship with our usual breeding environment and personal conditions, but in the cold winter, for many ornamental fish lovers, it is still inclined to warm these cold-water fish to raise and raise. The old way of fish farming has long said, the name of cold-water fish is conventional, many aquarists have been accustomed to goldfish, koi, grass goldfish called cold-water fish, we should not have any objections to these names, there is no need at all.

In the case of the water temperature close to around zero, these cold-water fish can also spend the winter outdoors, this problem fish farming old Tao has also said, either we raise them the water level is deeper, preferably in a fish pond above one meter, especially for larger koi fish, although the water surface is frozen, but below the ice on the water surface, it will probably still be in the range of zero degrees, unless our local temperature is too low, then it depends on the depth of the pool. In addition, the goldfish raised by the old fish farmers in the past are buried in the ground with half of the water tank, and then they can be covered with plastic sheeting, leaving a certain gap, because in the winter here, we can see the temperature of minus seven or eight degrees, that is, the longest time for a week, and then the temperature will rise slowly, and then you can also use furnace ash to keep the bottom of the tank above the ground warm. All in all, as long as the fish tank or fish pond is not completely frozen by ice, and there is living water suitable for fish swimming under the water surface, these ornamental fish will not be frozen to death, of course, if they can be properly allowed to accept some warm winter sun, or we regularly do itCleanupThe water surface is too thickIce, all of them are okay.

If it is a cold-water fish that has been living outdoors, the water temperature drops gradually, the fish have no diseases, and the physique is strong, so we save itA lot of troubles to manage in winterWhen the water temperature is below 10 degrees, you basically don't need to feed it, and wait until next spring. If the temperature is too low, you can also take appropriate measures to keep warm, such as the above-mentioned furnace ash, plastic sheeting, straw curtain, plastic greenhouse, etc. If we want to enjoy aquarium fish, it's best not to leave them outdoors anymoreIt's better to move indoorsBy the same token, as long as the indoor freeze does not freeze, the fish will not freeze to death, but the main problem remainsThe water temperature drops graduallyAnd the fluctuations up and down are not big, we can't say that there is no one at home during the day, the water temperature is two or three degrees, and after going home, there is a heating equipment, and the water temperature is above 25 degrees, so no matter what kind of ornamental fish it will get sick.

Yes, the general breeding season for goldfish is at the turn of spring and summer every year. The south of our country is 1-2 months earlier than the north, spawning between March and April in the south and the end of April to the end of June in the north. Goldfish usually mature and spawn in 1 year.

Goldfish are still relatively harsh on temperature conditions, so it is difficult to reproduce without low temperatures, and various problems will occur.

Goldfish is an oviparous fish, dioecious, belongs to in vitro fertilization of ornamental fish, the general goldfish in the water temperature reaches about 20 degrees, the age of the fish can be reproduced for more than a year, the age of the fish is not smaller, but the spawning rate is different, even if the domestic goldfish can breed a hundred and eighty we are also very happy.

Goldfish will be kept at a constant temperature will be good. A true constant temperature of 24 degrees can raise fish, such a temperature is most suitable for raising koi and goldfish, the temperature of the water has always maintained a certain temperature, such water quality is quite good.

Koi fish and goldfish have a high survival rate in such water, and the fish will not get sick, which is very rare, and it is very good for goldfish to always maintain such a water temperature.

Morphological characteristics

Goldfish is a variant of crucian carp. After artificial breeding, the body size varies greatly. The body length is generally 6 to 10 cm.

The head and abdomen are large, and the tail is divided into single tail and double tail. The head changes greatly, there are many kinds of flat heads, lion heads, goose heads and pompoms, and there are strawberry-like tumors in addition to flat heads. The eyes are bulging, the eyeballs are enlarged, and their shapes include longan, uplifting, blister eyes, etc.

The gills have normal gills and antigills.

In addition to normal scales, the scales also have transparent scales and pearl scales, and lateral line scales 22 to 28. The fins are large, the dorsal fin is present or absent, the anal fin has single and double fins, and the caudal fin is mostly divided into 3 or 4 lobes and scattered. The color of the body varies greatly, including gray, black, white, purple, blue, orange-red, bronze, miscellaneous spots, and five flowers.

Goldfish can reproduce naturally in a fish tank, but of course certain conditions are also required.

1.First of all, it is necessary to ensure that the goldfish in the tank are both female and male;

2.The feed for goldfish is nutritious, and the amount of food for females in the breeding season is very large, and the nutrition cannot keep up;

3.Excellent water quality and high dissolved oxygen;

4.The end of April to the beginning of May every year is the breeding season, once the male fish is found chasing the female, it will soon produce fish roe, at this time should be placed in the tank snapdragon (can also be bionic grass), pay close attention to the changes in the tank, once the fish is found to produce fish roe, you should take out the grass attached to the fish roe as soon as possible, put it in a small container to hatch;

5.As long as the feeding is good, generally in April and May every year, the gonads of female and male goldfish in the aquarium, porcelain tank, and fish basin can also develop and mature, and the phenomenon of chasing occurs. For example, different species are mixed in containers such as aquariums, and they should be temporarily separated according to the species.

If the aquarium is not enough, you can use a white enamel basin as an spawning pool or egging pool, but the water should not be too full, and cover the basin with a net to prevent the broodstock from chasing fiercely or jumping out of the basin during spawning and causing injury and death. In addition, the aquatic plants should also be prepared in time, and the fish nest should be made into bundles for standby, and the particularly favorable conditions are that when the family breeding goldfish reproduces, the temperature can be controlled with an electric heating rod in the aquarium or tank and basin, and the water is kept at a constant temperature of 18 degrees to achieve the best reproductive effect. The small fish do not need to be fed for the first three days after hatching, and they are fed with gray water on the fourth day, and egg yolk water can also be fed when there are no conditions.

Hello dear, goldfish can breed small fish, but goldfish will only mature and begin to reproduce after a year of growth. Goldfish do not reproduce like mammalian hailstones that are viviparous, but oviparous, so they cannot directly give birth to small fish. Specifically, at the time of reproduction, the female will ovulate first, and then the male will sperm to fertilize the eggs, making them fertilized eggs.

Under the conditions of suitable water temperature, after 3-7 days, the fertilized eggs will hatch into small goldfish. Hope it helps you <>

Do you have any other questions that I need to answer for you? <>

The ideal temperature for goldfish breeding is 22 to 24 degrees Celsius.

The water temperature below 10 degrees Celsius will slow down the heartbeat, breathing, and greatly reduce food, stop growing and enter hibernation; Above 30 degrees Celsius, the food intake decreases, and the growth is slow. When replacing the temperature difference of the water body, the big fish should not exceed 4 degrees Celsius, and the small fish should not exceed 2 degrees Celsius to adapt to the situation.

Summary. As long as more than 1 year of goldfish can reproduce, generally called 1-year-old fish, goldfish breeding period, generally in April to June every year, start breeding, the general breeding period can lay 5-7 eggs. It can lay eggs ranging from hundreds to thousands at a time, and generally only if you find that one fish has been chasing another fish, this is called tailing, which is a sign that the goldfish is about to spawn, and you can fish out the pair separately and let it reproduce.
