CATDOLL : CATDOLL: Can crucian carp and grass carp be raised together?

1. Can crucian carp and grass carp be raised together?

Yes, grass carp eats grass.

Crucian carp eats grass carp feces.

This way you can know

There are more grass carp than crucian carp.

I think this is OK, 10 to 1

That should be it.

In fact, fish are not afraid of being crowded, but they are afraid of lack of oxygen.

You'd better put some oxygen in it, so you won't be afraid of too many fish.

2. What kind of grass does grass carp like to eat the most? Can grass carp be raised together with crucian carp?

Grass carp likes to eat grasses such as Vallisneria serrata, Vallisneria spinulosa, Vallisneria serrata, water sieve, black algae, Agave tongue, shrimp grass, water cabbage, etc. of the family of Hydrocharitaceae, Cyperus oleifera, Cyperus capitatus, Cyperus serratus, Eupatorium edulis, Cyperus heteromorphus, etc. of the family of Cyperus, Duckweed, Duckweed, Spirodendrum dahliae, Pinalgae, etc. of the family of Lemnae, and Setaria officinalis, Sudan grass, rye, reed, etc. of the family of Poaceae. When breeding grass carp, it can be mixed with crucian carp, which can not only give full play to the production capacity of the water body, but also does not affect the growth and development of the fish body.

1. What kind of grass does grass carp like to eat most?

Grass carp is a typical herbivorous fish, and the green grass feed it likes to eat is generally as follows:

1. Hydrocharitidae

Grass carp likes to eat plants of the Hydrocharitaceae family, such as Vallisneria paniculata, Vallisneria spinulosa, Vallisneria densely spiny, water sieve, black algae, Agave, Shrimp Grass, and Water Cabbage.

2. Cyperaceae

Cyperus plants are also the favorite forage of grass carp, such as oil sedge, capitate sedge, water sedge, water chestnut, cow-hair felt, water plantain, and sedge of different shapes.

3. Duckweed

Grass carp, especially small fish, particularly like to eat duckweed plants, such as duckweed, water melon, Spirulina, and Pinalpa.

4. Gramineae

Poaceae plants such as foxtail grass, Sudan grass, rye, reeds, corn, wheat, rice, sorghum, oats, etc. are also plants that grass carp likes to eat.

2. Can grass carp be raised together with crucian carp?

1. Grass carp can be mixed with crucian carp. Grass carp generally likes to live in the middle and lower layers of water and near the shore with a lot of aquatic plants, while crucian carp likes to move at the bottom of the water. Mixing them can not only give full play to the production capacity of the water body, but also does not affect the growth and development of the fish. The ratio of grass carp to crucian carp can be controlled between 1:1.2-1.5.

2. Avoid mixing grass carp with fry that have interspecific competition, otherwise it will affect the growth of grass carp. Grass carp mainly feeds on various aquatic plants, algae and plankton, while crucian carp is omnivorous, so when mixing them, it is better to strengthen the counterpart feed for grass carp.

3. How to raise crucian carp at home and what to feed it?

Just use unpolluted water for breeding. Now the water we use for breeding fish is mostly tap water, so the first step in breeding water is to remove the toxic substance in tap water - chlorine. The method of dechlorination is relatively simple. After the water is collected, let it stand for 2-3 days, or dry it in the sun for 1 day (if it is urgent, you can add 0.63 grams of baking soda, that is, sodium thiosulfate, per 100 kg of water and use it immediately).

You can feed him phytoplankton, moss, earthworms, shrimps, blood worms, rice grains, corn grains, wheat grains, bean flour, and corn flour.

1. Always pay attention to increasing the oxygen content in the water.

2. Do not keep it together with other carnivorous fish to prevent the crucian carp from becoming feed.

3. In most cases, crucian carp will not jump out of the water, which is completely different from carp.

4. Feed in moderation. Feeding too much will easily deteriorate the water quality. Feeding too little will make the fish smaller and smaller until they grow as thin as a dagger.

5. If you use tap water when changing the water, expose the water to the sun for three days.

6. Get adequate sun exposure.

7. The water temperature should be constant.

8. Every time you change the water, leave some old water and then add new water.

Particle size and feeding rate of crucian carp:

The selection standard of crucian carp feed particle size is "small rather than large". Generally, when the crucian carp size is less than 10 grams per tail, the feed particle size is 0.5mm; when it is 10-30 grams per tail, it is 1.5mm; when it is 75-100 grams per tail, it is 2.0mm; when it is 150-300 grams per tail, it is 2.4mm; when it is more than 300 grams per tail, it is 3.2mm.

The feeding capacity of fish is directly affected by the size of the fish and the water temperature of the pond, so the feeding rate should be adjusted randomly according to the actual situation and should not remain unchanged.

Adult crucian carp mainly feed on plant-based food. Since plant-based feed is abundant in water bodies and has a wide variety of species, it is widely available for feeding. The stems, leaves, buds and fruits of vascular aquatic plants are crucian carp's favorite food. In waters with higher aquatic plants such as water chestnuts and lotus roots, crucian carp can obtain a variety of rich nutrients.

Diatoms and some algae are also food for crucian carp, as well as small shrimps, earthworms, young snails, insects, etc.

Seeing that you are talking about small crucian carp, we can rule out the possibility that they are temporarily raised for the purpose of preserving freshness.

Crucian carp is an omnivorous animal and is easy to raise. If you don't want to buy food outside, you can feed it with rice or steamed buns. In addition, water plants in the pond can also be fed.

When feeding, you should change the water frequently, usually every 3 to 5 days.

When changing water, please note: you can only change one-third to one-quarter of the water. Do not change a lot at once, as the fish will not be able to adapt. It is very important to keep the water in the aquarium clear.

Symptoms of Crucian Carp Red Gill Virus

The main symptoms of gill bleeding are: the body of the diseased fish turns red, especially below the side scales and on the chest, the gill cover is swollen, and blood will flow out of the gills when the gill cover opens and closes or the fish jumps. Because the gills of the diseased crucian carp are edematous and watermelon-colored, farmers call it big red gills. If not treated in time, it can cause gill bleeding in June and July.

Gill hemorrhage disease is fierce and there is no effective drug control so far. According to the experience in recent years, the best control measure is to adopt a stress control system to prevent and alleviate the disease. It is an organic combination of four major technologies: stress control technology, niche control technology, immune control technology and drug control technology. This control system must run through the entire breeding period.

Emergency Plan for Ponds with Severe Gill Bleeding Disease

The oxygenator must be turned on at midnight every day;

At the same time, add 5 kg/ton of antiviral Chinese medicine to the feed on the first day, and use it for three consecutive days. The medicine should be fed once a day, and no more than twice a day.

The next morning: strong oxygenation bottom modification, 1 kg/mu・m, can also be used on rainy days;

Morning of the fourth day: Sprinkle the whole pond with Sanbao Vitamin C, 100g/mu・m;

On the afternoon of the fourth day: Sanbao methionine iodine 50 ml/mu・m, stop feeding antiviral Chinese medicine in the feed, and add 5 kg/ton of astragalus complex polysaccharide to the feed instead. Use it for three consecutive days, one meal a day, no more than two meals a day, and a course of treatment is 7 days.

Emergency plan for ponds with mild cases of gill hemorrhagic disease

Oxygen should be turned on at midnight every day;

First day morning: Sprinkle the whole pond with Sanbao Vitamin C, 100g/mu・m;

On the first day, add 5 kg/ton of antiviral Chinese medicine and 5 kg/ton of astragalus polysaccharide to the feed, and use it for three consecutive days. The medicated bait should be used once a day, and no more than twice a day.

The next morning: strong oxygenation bottom modification, 1 kg/mu・m, can also be used on rainy days;

On the morning of the fourth day: spray the whole pond with Sanbao Vitamin C, 100 g/mu・m; in the afternoon: Sanbao Methionine Iodine 50 ml/mu・m, stop feeding antiviral Chinese medicine and Astragalus complex polysaccharide in the feed, and add 5 kg/ton of antibacterial peptides to the feed instead. Use it for three consecutive days, one meal a day, no more than two meals a day; 7 days is a course of treatment.

This solution is more suitable for ponds where big red gill and other bacterial diseases are more serious and gill hemorrhagic disease is relatively mild.

Note: In ponds with gill bleeding, it is strictly forbidden to use pesticides, disinfectants, change water, divide ponds or merge ponds, etc.

Hello, I caught 100 small crucian carps yesterday. Since I was fishing in a small water area and the water was used to irrigate wheat, the water was almost dry, so I finally put the crucian carps in the Yellow River. So the best way to raise the crucian carps is to release them into a larger water area to give the fish more freedom.

If you keep a fish in a fish tank, it will die sooner or later. Instead of watching your beloved fish wither day by day, it is better to choose to release it directly into nature. There is a kind of love called letting go. If you catch it, it means you have a connection with it. Since you have a connection with it, be a kind person and release the fish back to nature.

I was young and ignorant before, and I didn’t have the understanding I have now. I also loved fish, and every time I caught a fish, I would always think about raising it. I fed it steamed buns every day, but because the steamed buns were atomized in the water and the water quality deteriorated, the more I fed it, the more it died. I really loved it in the wrong way.

When you catch a lot of crucian carp in the wild, but don't want to give them away, you want to keep them for a while and then store and retrieve them freely. This is of course possible, provided that you have some equipment, a larger pool or water tank, a natural water source, and matching water pipes and oxygen pumps.

During each wild fishing, pay attention to protecting the fish body after catching it to avoid hurting the fish. This means that you should not play the fish for too long, do not take the fish by hand, and use a needle guard. Use barbless hooks as much as possible. Use a large fish guard and do not use a black pit guard to prevent hurting the fish. When transporting home, put it in a fishing box, add water, increase oxygen, and keep the speed steady.

When selecting and raising fish, you should pay attention to selecting individuals with good fur and strong activity and put them into a large container in time, turn on the aerator, and change the water every two or three days according to the temperature, each time for one-third of the total capacity. When feeding bait, you can use commercial bait, rice, corn flour, etc., or insect bait, red worms, earthworms, thread, or green leaves and moss. Be careful not to put too much in to avoid extremes. Pay attention to the oxygen content of the water and the water temperature control to avoid fish death due to too high or too low temperature. Of course, after a long time, you will also find out some breeding experience, which is great, isn't it?

Crucian carp will bite water plants because that is one of its staple foods. There is no problem raising it with goldfish because goldfish are improved crucian carp and the two are of the same genus.

(Carp [the larger one on the left] and goldfish are kept together)

Adult crucian carp mainly feed on plant-based food. Since plant-based feed is abundant in water bodies and there are many varieties, there is a wide range of food for it. The stems, leaves, buds and fruits of water plants are the favorite food of crucian carp. In waters with higher aquatic plants such as water chestnuts and lotus roots, crucian carp can obtain a variety of rich nutrients. Diatoms and some algae are also food for crucian carp, as well as shrimps, earthworms, young snails, insects, etc.

Wild crucian carps like to travel in groups, sometimes with the current, sometimes against the current, to shallows with lush aquatic plants, river bends, ditches and reeds to look for food and lay eggs; they will temporarily rest when they encounter places with slow or still water and abundant bait.

Additional information:

Goldfish and crucian carp belong to the same taxonomic species (Carassius auratus).

Goldfish originated in China, also known as "golden crucian carp". It is similar to carp (Cyprinus carpio) but has no whiskers. It is an ornamental fish evolved from crucian carp. There are many varieties of goldfish, with colors such as red, orange, purple, blue, black, silver, and five-colored. They are divided into four major strains: Wen, Cao, Long, and Dan. Genetic research on the domestication of goldfish began in the 12th century. Now, goldfish in various countries around the world are directly or indirectly introduced from China.

In the history of human civilization, Chinese goldfish has been with human beings for more than a dozen centuries and is the earliest species in the history of ornamental fish in the world. Goldfish is easy to raise, with strange shapes, bright colors, generally golden yellow, and beautiful shapes. Goldfish can beautify the environment and are very popular among people. It is an ornamental fish with Chinese characteristics. China's goldfish is mainly developed from crucian carp.

There are two different purposes for keeping crucian carp at home. The feeding situation will also be different:

1. Temporary storage for the purpose of preservation.

Live fish are fresher. The best way to preserve live fish that are not eaten immediately is to keep them. If you keep crucian carp at home for the purpose of keeping them fresh, it is best not to feed them. Not feeding them will not produce excess feces and leftover bait, which is conducive to maintaining water quality. Moreover, not feeding them for a few days will not consume a lot of crucian carp's nutrition. The way to keep them is also relatively simple. Find a container as large as possible to hold tap water, add baking soda in proportion, and add an air pump if conditions permit.

2. Long-term breeding for viewing purposes.

This breeding is much more complicated, and requires the purchase of a large number of fish farming equipment, from water quality maintenance to environmental layout, and a series of measures. You can refer to some books and websites on goldfish (carp variants) breeding. In addition, it is recommended to use artificial feed, which is more nutritious and less likely to pollute the water quality.
