CATDOLL : CATDOLL: In which month does herring lay eggs?

1. In which month does herring lay eggs?

I think black carp should lay eggs in June. In June and July in early summer, black carp lays a lot of eggs and the fish grow very fast.

Are you asking in which month herring lays eggs?

Herring does not lay eggs.

The breeding season of black carp is from May to July every year. The temperature suitable for the breeding and survival of black carp is 22-28 degrees. It will lay river-drifting eggs in rivers during the breeding season. Black carp can mature in 4-5 years.

2. Is herring a marine fish or a freshwater fish? Can it be farmed?

Black carp is a freshwater fish, not a marine fish. In my country, black carp lives in various freshwater basins and is widely distributed. They are widely distributed in the Yangtze River Basin and some freshwater basins to the south, but cannot adapt to life in seawater. Black carp generally lives at the bottom of the water and is a bottom fish. It can often be seen in waters rich in animals. In addition, there are also many artificially farmed black carps in my country, which generally live in breeding ponds or fish ponds.

1. Is herring a marine fish or a freshwater fish? Herring is one of the many fish species in my country. It is very common in daily life and is also an edible fish. Marine fish and freshwater fish are the classifications of all fish species. The difference between the two is relatively large. The most obvious difference is that the two can adapt to different living environments. Herring belongs to the latter and is a freshwater fish, not a marine fish. They cannot adapt to life in seawater and have always lived in freshwater.

Specifically, black carp lives in many different types of freshwater. There are more black carp in rivers, lakes and other freshwater basins. Especially in the Yangtze River Basin and some provinces in the south, there are more black carp. Black carp generally lives at the bottom of the water and is a bottom fish. It can often be seen in waters rich in animals. In addition, there are also many black carps living in artificial breeding conditions, which also adopt freshwater breeding methods. They generally live in breeding ponds.

2. Can black carp be farmed? As mentioned above, black carp can be farmed. In my country, there are not only a large number of wild black carp, but also a relatively large number of farmed black carp. Farming black carp is very common because black carp is a common economic fish that can be eaten and used as medicine, and its value in all aspects is relatively high. Since black carp itself is a freshwater fish, freshwater is also used for artificial breeding, and they can adapt well to the environment. In addition, during the breeding process, many factors in the freshwater environment need to be paid attention to, such as water temperature, water quality, and oxygen content.

3. In what season do fish begin to spawn?

Different groups of fish have different breeding habits and their gonadal development has different seasonal rhythms. Fish that spawn in spring and those that spawn in autumn have different seasonal rhythms. Generally speaking, ordinary fish can ovulate in the spring when the water temperature reaches above 20 degrees, which is after April. Artificial breeding of fish takes place during this period.

1. Crucian carp

March to July is the breeding season for crucian carp, with April being the peak breeding season. In the southern region, crucian carp generally begin to spawn after mid-March when the water temperature rises to around 17°C, and the breeding activity is at its peak when the water temperature rises to 20-24°C. Rainfall, micro-flowing water and sultry weather can induce spawning in the breeding season.

2. Carp

The spawning season varies with region. Spawning can occur from March to August, with the peak period being from April to June.

3. Grass carp

The reproductive season is from early May to early June, with the peak period being mid-to-late May.

4. Silver Carp

The breeding season is from mid-April to July, with a peak in May and June.

Additional information

What should you pay attention to during the spawning period of fish when raising fish:

1. Isolate male fish

Isolate the male fish to another tank and let the female fish give birth. It is not because you are afraid that the male fish will eat the small fish, this is just one of the reasons. The main reason is that you don’t want the male fish to chase the female fish. The female fish will be unhappy and run away, which will also cause tension.

2. Use drip water for water change

Even if you don't usually use drip water, please be gentle with the mother. It is best to use drip water or add water slowly when changing water. Normally, guppies don't pay much attention to water flow, but if a female peacock is about to give birth and is hit by a sudden water flow or a change in water temperature, it is very likely to cause premature birth.

This shocking premature birth is very harmful to the fish body, and it is possible that all unfertilized and immature eggs will be expelled. Of course, it will cause great harm to the mother fish, and the mortality rate of premature fish is also very high. Therefore, as mentioned in the previous article, it is necessary to prepare a breeding tank to avoid hastily changing the tank and isolating the mother fish when she is about to give birth, which is very likely to cause harm to the mother fish and premature birth.

3. Add obstacles: obstacles include water plants, stones, man-made objects, etc.

If it is water plants and stones, you can put them in the fish tank normally, that is, let the mother fish give birth in a completely natural situation. This method is best for the mother fish, but the survival rate of the small fish is the lowest, which usually depends on the mother fish's skill in eating the small fish.

When the mother fish is about to give birth, you can put a lot of water plants in the fish tank, about half of the tank, but you need to leave space for the mother fish to move around, so that she won't be squeezed and jump out of the tank. Recommended water plants include snapdragon, water hyacinth, moss, water hibiscus, etc. The best effect is to use water hibiscus and snapdragon together. At the same time, water hibiscus is a floating water plant, which can calm the mood of the mother fish.

Breeding season for freshwater fish:

1. Crucian carp

March to July is the breeding season for crucian carp, with April being the peak breeding season. In the southern region, crucian carp generally begin to spawn after mid-March when the water temperature rises to around 17°C, and the breeding activity is at its peak when the water temperature rises to 20-24°C. Rainfall, micro-flowing water and sultry weather can induce spawning in the breeding season.

2. Carp

The spawning season varies with region. Spawning can occur from March to August, with the peak period being from April to June.

3. Grass carp

The reproductive season is from early May to early June, with the peak period being mid-to-late May.

4. Silver Carp

The breeding season is from mid-April to July, with a peak in May and June.

5. Black carp

The spawning period in the Yangtze River, Pearl River and Xijiang River is from March to June.

6. Whitefish (white silk, white fish)

Spawning in June and July.

Different groups of fish have different reproductive habits and different seasonal rhythms of gonadal development. Fish that spawn in spring and those that spawn in autumn have different seasonal rhythms. Generally speaking, common fish can ovulate in spring when the water temperature reaches above 20 degrees, which is after April. Artificial breeding of fish is carried out during this period.

You can't fish in summer when fish are spawning. The ancients said.
