CATDOLL : CATDOLL: Fish that lay floating eggs? How many eggs does a fish lay at a time?

1. Fish that lay floating eggs?

Silver carp and bighead carp also known as bighead carp lay floating eggs.

Additional information:

Bighead carp lays drifting eggs. Sexual maturity occurs at 4-5 years old, with males at the youngest at 3 years old. The breeding season is from April to July. Spawning grounds are mostly in places with uneven riverbeds and complex flow patterns. When it rains in the basin, the water level rises suddenly and the flow speed increases, breeding activities take place. The longest age is 20 years.

In the mainstream of the Yangtze River in China, they generally mature at the age of 5. In the reproductive population, the age sequence is the shortest, with individuals aged 5 to 7 accounting for more than 90% of the total, with a body length of 950 to 1050 mm and a weight of 15 to 19 kg. The smallest mature male is 6 years old, 890 mm long, and weighs 11.4 kg. The female is 5 years old, 800 mm long, and weighs 8.5 kg.

2. How many eggs does a fish lay at a time?

Different fish produce different numbers of eggs during their life cycles and breeding seasons. Generally speaking, small fish produce fewer eggs, with the number of eggs laid each time being only a few dozen to a few hundred, while larger fish may lay tens of thousands of eggs at a time. For example, salmon can lay thousands of eggs at a time, while shellfish such as clams and oysters may produce tens of thousands of eggs a year. In addition, fish reproduction is also affected by a variety of factors such as the environment and climate. The number of eggs produced is not the only influencing factor, and stages including mating, fertilization and hatching may also be affected by environmental factors, affecting the survival rate and survival rate of fish reproduction.

3. What are the aggressive fish?

Piranhas, sharks, crocodiles, and bighead carps are very aggressive.

4. How many eggs does a raw fish lay at one time?

How many eggs does a fish lay at a time? About 100,000 eggs, but the survival rate is very low.

5. How many eggs does an angelfish lay at a time?

Ranges from 400 to 1000.

The number of eggs laid depends on the size of the adult fish and generally ranges from 400 to 1000.

Angelfish reproduction goes through a process of egg care: Angelfish larvae begin to hatch, but still cannot swim. They cling to this place, spend a long 4-5 days by absorbing their own vitellogenin, and begin to release their spawning grounds, feeding on tiny water fleas. Female and male fish still take care of the young angelfish in every possible way.

6. What fish lays its eggs on wood?

There is a fish that can climb trees in the Binglang River, called "Stone Flathead" or "Stone Sticker". Because of its large head, it is also called "Big Head Fish". The most popular name is "Tree Climbing Fish". This is because they can attach their bodies to stones or trees and move left and right, up and down.

Every year when the rainy season comes, the trees in the river are submerged in water. This fish takes this opportunity to swim to the surface of the water, cling to the tree trunks to avoid the muddy water, and prepare to lay eggs on the trees. As the flood gradually subsides, the fish lying on the tree trunks also emerge from the water and lay their eggs on the trees. This fish is very rare and can only be found here. It is a giant panda in the water.

7. How many eggs does bighead carp lay at one time?

About 1 million pills

The Chinese catfish is a fish that lays drifting eggs. Its breeding habits and artificial breeding techniques are basically the same as those of the four major carps. Moreover, Chinese catfish generally reach sexual maturity at the age of 4, with a body length of more than 1 meter. Female fish can carry about 1 million eggs, and a single spawning can provide a huge number of seedlings. Finding ways to improve the spawning rate of parent fish, the fertilization rate and hatching rate of eggs, and the survival rate of newly hatched fry has become the key to seedling technology.

Therefore, there is not much pressure on the supply of seedlings, but the difficulty in breeding bighead carp lies in the domestication of its feeding habits: like mandarin fish, bighead carp only eats biological bait and does not eat artificial compound feed. Therefore, if you want to breed bighead carp, you must prepare sufficient bait fish from the seedling stage.

8. How often does the croaker lay eggs?

Fish lay eggs about three times a year. Fish, like other animals, reach sexual maturity at a certain age, and the time varies greatly from species to species. For fish like guppies, sexual maturity takes three to six months, while larger fish, such as dragon fish, take four to eight years. Moreover, the time of sexual maturity can also be different for the same fish, whether it is male or female.

9. How many eggs does yellow bone fish lay at a time?

The absolute egg-carrying capacity of yellow croaker (the total number of eggs carried by a female fish) is 2,500-16,500, with an average of about 4,000 eggs.

The relative egg-bearing capacity of yellow croaker (the number of eggs per unit body weight) is 58.33-77.77 eggs/g, with an average of 65.71 eggs/g.

Each mature yellow bone fish can generally lay eggs 2 to 3 times, and up to 4 to 6 times. Under normal circumstances, the interval between each spawning is about 10 days.

10. How often does a zebrafish lay eggs?

In about 7 to 10 days, it can reproduce 6-7 times a year.

Secondly, whether zebrafish lay eggs or not depends on how well you feed them. Some well-fed ones can lay eggs once in less than a week. In addition, if the breeding environment is poor, they will not reproduce continuously.

Zebrafish lay eggs once a week. They can reproduce when they are about 3 months old. However, it is best to choose zebrafish over 6 months old for breeding. They have a very strong reproductive ability and can continue to reproduce after resting for about a week after laying eggs. However, it is not recommended to let the same fish mate and reproduce frequently during breeding, otherwise it may cause genetic deterioration.
