Question 1: How do lion-head goldfish reproduce? Generally speaking, the belly of female fish during spawning period is larger, while the belly of male fish has no changes. However, upon closer inspection, it is not difficult to find that there are several small white dots on the front bony spines of the left and right front fins of the male fish, especially during the spawning period, but there are absolutely none in the female fish. In addition, during the spawning period, the male fish always chases and bites the tail of the female fish. At this time, the eggs are about to be laid. The pair of fish should be placed in a separate fish tank with a little more aquatic plants in the tank to facilitate the laying of fish eggs. It can adhere to aquatic plants, otherwise the eggs will sink to the bottom of the water and be eaten by fish. After spawning, the female fish should not be mixed with any male fish for the time being, and let it fully rest and recuperate to protect the female fish. Place the aquatic plants with fish eggs attached to them in a fish tank with fish water (preferably a tile tank), and place them where the sun can shine. The breeding season of goldfish is at the turn of spring and summer every year. In the south of my country, eggs are laid 1-2 months earlier than in the north. In the south, eggs are laid between March and April, and in the north, eggs are laid from the end of April to the end of June. Goldfish usually mature and lay eggs in one year, which means they can reproduce one generation every year. If the temperature is raised in winter and feeding and management are strengthened, goldfish can lay eggs in advance in the severe cold winter when they are 7-8 months old. They do not have to be one year old (12 months old) before they can lay eggs and reproduce. Goldfish can lay eggs multiple times during the breeding season. They give birth about once every one or two weeks and can give birth 2-3 times. Wherever it is irradiated, small fish will hatch in about a week. The gender of goldfish can change. For example, two all-female fish or two all-male fish are kept together. After a period of time, they will become one female and one male.

Artificial insemination of goldfish

Under normal circumstances, goldfish broodstock with well-developed gonads can mate naturally and lay healthy fertilized eggs. But when people want to cross-breed new species, or when there are many female fish of a certain species but only one or two male fish, we can use artificial insemination to breed goldfish. Artificial insemination can make up for the shortcomings of natural fertilization, greatly improve the utilization rate of sperm and eggs, and can consciously cultivate new varieties of high quality according to production needs. There are two methods for artificial insemination of goldfish, which can be carried out with water or dehydrated. ① Water insemination: Use a large-mouth, shallow-bottomed white basin, fill it with 1/2 of the clean, dried tap water, and put an appropriate amount of hornwort or foxtail algae bundles to make them float in the water. Then, each of the left and right hands lifts the determined standard broodstock in the water, so that their cloaca openings face each other, and gently squeezes the abdomen of the male broodstock with the thumb to squeeze out the milky white sperm. At the same time, the thumb of the other hand also squeezes gently. Press the abdomen of the female parent fish to squeeze out the mature eggs. *** Completes the fertilization process with the eggs in the water, and the fertilized eggs will immediately adhere to the aquatic plants. In order to ensure that the fertilized eggs hatch normally, the aquatic plants with fish eggs attached to them should be immediately moved to another water body with better conditions to hatch the seedlings. ② Out-of-water insemination method: Take out a pair of male and female broodstock that have been determined to standard, dry the fish body with soft gauze, gently press the abdomen of the male fish with your thumb, squeeze out the sperm, put it in a dry glass container, and then Quickly squeeze the female fish's abdomen with your thumb to squeeze the mature eggs into a glass container containing sperm. At the same time, take a dry feather and stir the sperm and eggs together. Then pour the fertilized eggs onto the fish nest. When the fertilized eggs encounter water, they will become sticky and will immediately adhere to the aquatic plants and then be sent to hatch. With out-of-water insemination, the sperm of one male fish can fertilize the eggs of multiple female fish, which can fully save the amount of male fish.

Question 2: Lionhead Goldfish Reproduction Although 1-year-old goldfish can mature and lay eggs, they can be used as scientific research materials. However, due to the small number of eggs it carries, production units generally do not choose it as broodstock. Fish over 5 years old are generally not suitable for breeding because their reproductive potential has passed and gradually declined, resulting in an increased rate of deformity in their offspring. The fertilization rate and hatching rate are higher among 2 to 4-year-old fish.

Question 3: How old can lion head goldfish be to breed? Although 1-year-old goldfish can mature and lay eggs, it can be used as scientific research material. However, due to the small number of eggs it carries, production units generally do not choose it as broodstock.

Fish over 5 years old are generally not suitable for breeding because their reproductive potential has passed and gradually declined, resulting in an increased rate of deformity in their offspring. The fertilization rate and hatching rate are higher among 2 to 4-year-old fish.

Question 4: When do lion-headed goldfish reproduce? Generally, 2-year-old goldfish will rear their tails and produce seeds to reproduce in the spring and autumn. Lionhead goldfish are also goldfish. This phenomenon will occur as long as male and female goldfish 2 years old and above are together.

Question 5: These two lion head goldfish cost 50. Is it worth it? About 17 cm long, 2 year old fish. How to tell the difference between male and female? How to reproduce? The bifurcation of the tail fin cannot be seen clearly, but the bulge on the head and the color are fine. Male and female can only be distinguished by certain experience. You can hold the goldfish flat with one hand, and separate the cloaca from front to back with the thumb and index finger of the other hand. Compare The round ones are female, and the pointed ones are male

Question 6: How to distinguish male and female goldfish with lion heads. Please provide a diagram to distinguish male and female goldfish with lion heads as follows: (1) Differences in external appearance: (1 ) Differences in body shape: Male goldfish are generally slightly longer, while female goldfish are shorter and rounder. During the pregnancy period, the abdomen of female fish is enlarged compared to that of male fish. (2) Differences in caudal peduncle: Male fish are slightly thicker than female fish. (3) Differences in pectoral fins: Careful observation shows that the male fish is slightly pointed and longer, and the first spine of the pectoral fin is thicker and harder; the female fish is short and round, and the first spine of the pectoral fin is not too hard. (4) Differences in cloaca: Looking up from the belly, the male fish’s cloaca is small, narrow, and concave; the female’s cloaca is large, slightly round, and convex outward. (2) Differences in color: Male and female goldfish have slight differences in body color. Male fish are generally brightly colored, while female fish are slightly lighter. During the reproductive and development period, male fish are more brightly colored. (3) Feel and movement: Gently hold the fish's abdomen with your hand, and feel an obvious hard line on the abdomen of the male fish with your middle finger and ring finger, while the abdomen of the female fish is softer. When walking by the fish pond, I stamped my feet and observed. The male fish swims fast and agile, while the female fish moves slower. (4) Star chasing: As the temperature rises, goldfish will have a second characteristic during the spawning period - star chasing. This is the easiest and most accurate time to identify the gender of goldfish, and it is also the easiest method to master. The star chasers of male fish appear on the first spine of the pectoral fin and the edge of the gill cover. Often there are star chasers on each ray of the entire pectoral fin. The ones at the front end are obvious, and the ones at the back can only be observed carefully. This kind of rough little thing is star chasing. Using the above identification methods, you must also rely on many years of breeding experience and daily careful observation to accurately identify the male and female goldfish.

Question 7: How to grow the head of a lion-headed goldfish? Feed live bait, fish, insects, water and earthworms. Pay attention to disinfection and sterilization.

Question 8: How to distinguish the tips of the reproductive pores of male and female lion-headed goldfish. Thin and thin (left) The genital pore of the female fish is large and round (right)

Male and female goldfish are mainly distinguished from the following aspects:

(1) Differences in external appearance:

(1) Differences in body shape: Male goldfish are generally slightly longer, while female goldfish are shorter and rounder. During the egg-pregnancy period, the abdomen of female fish is larger than that of male fish.

(2) Differences in caudal peduncle: male fish are slightly thicker than female fish.

(3) Differences in pectoral fins: Careful observation can reveal that the male fish is slightly pointed and longer, and the first spine of the pectoral fin is thicker and stiffer; the female fish is short and round, and the first spine of the pectoral fin is not very strong. hard.

(4) Differences in genitals: Looking up from the belly, the male fish’s genitals are small, narrow, and concave; the female fish’s genitals are large, slightly round, and convex outward.

(2) Differences in color: Male and female goldfish have slight differences in body color. Male fish are generally brightly colored, while female fish are slightly lighter. During the reproductive and development period, male fish have darker body colors. To be bright.

(3) Feel and movement: Gently hold the fish’s abdomen with your hand, and feel an obvious hard line on the abdomen of the male fish with your middle finger and ring finger, while the abdomen of the female fish is softer. When walking by the fish pond, I stamped my feet and observed. The male fish swims fast and agile, while the female fish moves slower.

(4) Star chasing: As the temperature rises, goldfish will have a second characteristic during the spawning period - star chasing. This is the easiest and most accurate time to identify the gender of goldfish, and it is also the easiest to master. a method of identification. The star chasers of male fish appear on the first spine of the pectoral fin and the edge of the gill cover. Often there are star chasers on each ray of the entire pectoral fin. The ones at the front end are obvious, and the ones at the back can only be observed carefully. This kind of rough white dot is star chasing.

Using the above identification methods, you must also rely on many years of breeding experience and careful observation to accurately identify the male and female goldfish.

Question 9: Can black dragon eye goldfish mate with lion head goldfish? As long as they are fish, they can mate... It’s just a question of what kind of seedlings will come out... If they don’t look like 4, there’s no need!
