When do goldfish lay eggs?

The specific time and water temperature are related to the spawning of goldfish. As long as they are properly raised and managed, the broodstock can spawn every spring, and some will also spawn in the autumn. The specific time varies slightly depending on the temperature in different places. Sometimes farmers use temperature, water quality, air pressure, light, dissolved oxygen and other conditions to control the spawning time of goldfish. Experiments have shown that when goldfish spawning activities are slow, using an oxygen pump to provide water flow and increase oxygen in the water, goldfish chasing each other to spawn will immediately become more frequent.

The spawning time of goldfish, during the breeding season, is usually from 4-5 o'clock to around 10 o'clock in the morning, which is the peak spawning time. Mature broodstock sometimes lay eggs after being replaced with new water at 5-6 o'clock in the afternoon, and a few fish also lay eggs at night.

The number of eggs that goldfish lay each time varies. A strong goldfish can lay thousands of eggs at one time. It can give birth 2 to 2 times in a season.

There are signs of goldfish spawning:

1 Seasonal temperature

Generally in spring every year, the temperature reaches above 16 degrees, but the temperature is around 20 degrees Egg laying as well. Eggs will also be laid in autumn when the temperature is similar.

2 Weather Time

It is easy to lay eggs in the morning after rainy or foggy days. The time generally starts from early morning to around 9 am.

3 Change the water

You have just changed the water, especially the friction of the water flow on the fish body during the water change, which can promote spawning.

4 Chasing behavior

1) During the breeding season, male goldfish will chase female fish. At first, they only chase occasionally, and then the chasing behavior will become more and more frequent. , this is the courtship behavior of male fish.

2) Mature female fish will release sexual information before ovulation, luring male fish to step up the chase. At this time, the male fish will chase the female fish, headbutt the female fish’s abdomen, and collide with the body. Female fish, this means that the male fish is ready to discharge semen at any time.

3) When the male fish always chases the female fish and sometimes even knocks the female over, it means that eggs will be laid soon.

If the broodstock does not spawn in the spring, the following measures should be taken:

1). Find out the reason why the goldfish does not spawn in the spring. If there is a fish disease, the appropriate treatment should be prescribed according to the fish disease. , treat it; if the genital pore is closed and cold, you can use your fingers to rub the genital pore gently, stimulate it or squeeze it down; if you are too fat and the fat layer is too thick, it is difficult for nutrients to enter the ovary, so you need to reduce investment. Feed live animal feed and increase fish stocking density appropriately.

2). In spring, add live food to the broodstock fish that have not yet spawned, replace them with 1/5-1/4 of the new water every day, and add an oxygen pump to the tank if conditions permit.

3). Increase the number of male goldfish, strengthen the pursuit of female goldfish and the temptation and stimulation of male hormone secretion.

4). Malnourished broodstock should be reared and fattened alone, and given enough live feed every day to keep the water green.

5). Water temperature and light not only promote the development and maturation of goldfish’s reproductive glands, but also improve the hormone secretion of goldfish’s pituitary gland and gonad function to some extent. Excited, if you want to breed broodstock again in autumn, you should try not to keep them in dark green water, appropriately increase the lighting time and raise the water temperature. Especially in the morning, if you see male and female goldfish following or chasing, you can use electricity to Warming up with a heating rod and oxygenating with an aeration pump will aid in successful fall breeding. To sum up, although there are many external factors that affect the time of goldfish spawning, the water temperature is one of the important conditions that directly affects goldfish spawning.
