What do small grass carp eat and how do they die in the spring?

As one of the four major fish, grass carp is very popular with the majority of Chinese, its eating habit is herbivorous, in order to let everyone further understand the eating habits of grass carp, in order for everyone to better breed, today I will introduce to you, what grass carp like to eat.

Method steps.

Grass carp is a typical herbivorous fish, and juveniles feed on rich animals in nature.

Juvenile fish like to eat turnip, duckweed, purple-backed duckweed, black algae, etc.

As for the adult fish, it likes to eat bitter grass, eye cabbage, etc., and under the conditions of artificial breeding, they like to eat terrestrial plants such as grasses and legumes in addition to aquatic plants.

At the same time, they also like to eat artificial bait, such as bread, bran, bran, etc.

It is worth noting that in case of hunger, grass carp will also eat some small fish.

At the same time, grass carp can also feed on putrefaction, and can be well utilized, this characteristic determines that grass carp is a very good breeding fish, but also greatly improves the status of grass carp in polyculture conditions.

1. Grasses. Generally, grass carp like to eat duckweed, aquatic weeds, and also like to eat a lot of early grasses, you can choose Mexican corn, tall single grass, Sudan grass, wolf's tail grass, alfalfa grass, rye grass, giant Juncao, these can be planted in the open field, and then used to feed. Sudan grass can also be planted at the edge of the pond, but growing pasture grass is the best way.

Do not feed grass with reticulated veins. The aquatic plants that grass carp like to eat are sedge, duckweed, etc.

2. How much grass you eat grows a pound.

Grass carp feed forage, about how much forage need to be fed, and finally grass carp will grow a pound of weight, aquatic experts believe that grass carp eat terrestrial grass 15 kg can grow a catty, grass carp eat aquatic grass to about 70 catties to grow a pound of meat, so in fact, when there is no water grass or little aquatic grass can be fed terrestrial planting grass.

3. Feed the forage.

Mainly feed young grass, or grass with less fiber, easy to digest and absorb, feed fresh grass, do not leave it for too long after cutting. It is best to feed terrestrial wild grasses, but if they are not available, they can be planted and fed. Feed the grass Don't feed the reticulated clumpy grass, feed the parallel vein grass, which is easier to digest, and don't feed the grass that the grass carp doesn't like.

Feeding forage must be cleaned before feeding.

4. Feeding method.

The mouth of the small fish is relatively small, to cut the fine grass to feed, do not feed the large, hard grass, you can fish the duckweed in the rice field and feed the grass carp, and when the fish grows up, you can gradually feed the larger aquatic plants, do not chop too much, you can also simply cut it, or feed it directly. Feed must be cleaned before feeding, do not feed grass that has been piled up, or has rotten grass. The specific feeding amount can be determined according to the weather, water quality, and other factors.

Clean water quality: If the water quality is too dirty, it is easy to cause small grass carp fry to die, so it is necessary to ensure the water quality by changing the water. Generally, it can be replaced once a week or so, and about one-third of each time is replaced.

The water temperature is suitable: it is best to keep it at about 20 degrees, and the minimum should not be lower than 10 degrees. Proper oxygenation:

Too little oxygen can cause grass carp fry to die, and some oxygen can be artificially replenished if necessary. Disease prevention: Regular disinfection should be carried out to prevent small grass carp fry from getting sick.

1. Clean water quality: small grass carp fry are also sensitive to the surrounding water quality due to their relatively young age. If the water is dirty, it will cause bacterial infection of the small grass carp fry, which may cause them to die.

Therefore, in order for them not to die, the water quality needs to be guaranteed. Depending on the situation, change the water every time you change it every time you do it a week or so, and don't let the water quality change too much, you can change about one-third.

2. Suitable water temperature: too low water temperature is also an important reason for the death of small grass carp fry, and they all like to live in warm water. Therefore, if possible, it can be kept at about 20 degrees, and no matter how low it is, it cannot be lower than 10 degrees.

3. Proper oxygenation: too low oxygen content in the water may also lead to the death of small grass carp fry. Therefore, when breeding small grass carp fry, if the air pressure is relatively low and the oxygen in the water is too little, a part of the oxygen can be appropriately supplemented.

4. Disease prevention: small grass carp fry are easy to get sick because their resistance is not particularly good, and they are easy to die at this time. Therefore, it is important to prevent diseases through measures such as disinfection, so that they are not easy to die.

1. Sufficient food: If you want small grass carp fry to grow quickly, you must provide sufficient and nutritious food. At this time, you can feed egg yolks and fish worms, which contain more protein.

2. Sufficient space: providing sufficient space for small grass carp fry is also an important aspect to promote their rapid growth. Although the size of the small grass carp fry is not particularly large, the number of stocking should not be too large, and it should not be too dense.

3. Suitable water environment: Maintaining a suitable water environment can promote the rapid growth of small fry. For example, the water temperature can be around 20 degrees; For another example, in order to ensure that the oxygen content in the water is sufficient, it can be appropriately oxygenated.

In summer, the water temperature is high and the breeding environment deteriorates. The one-year-old grass carp breeding period is in the middle of summer, the water temperature is generally above 30, at this time the water body is not only high in fertility, "over-fertilizer water" dissolved oxygen is low, and the feeding feed is very easy to deteriorate, so that the breeding environment deteriorates, resulting in fish disease breeding.

Care must be taken to ensure that the water quality is fresh. First, flush at the right time, 5 10 cm each time, especially in the high temperature season 1 2 days to flush once; The second is to fish out the dead fish and uneaten residual grass and sundries in time.

Summary. Dear, this season is the easiest to catch small grass carp.

Dear, this season is the easiest to catch small grass carp.

The grass carp is one of the most common species of jujube carp, and it is relatively easy to raise, especially between May and August, when it grows the fastest, and its body shape will change significantly.

The most suitable water temperature for grass carp is 27-30, when the amount of food eaten is the maximum, and too high or too low water temperature will reduce the amount of food it eats, and in severe cases, it will cause death. Grass carp usually refuse to feed on aquatic plants and other plant-based bait.
