Hello, I have seen your question and am sorting out the answer, please wait a while Hello It mainly depends on what kind of fry you raise.

Grass carp, carp, silver carp and silver carp are raised together.

How to do fish farming in new ponds.

Okay, so do you keep it in a fish tank or a pond?

Okay, wait a minute, I'll look up the relevant cases.

What is the best feed for the co-cultivation of three types of fishmeal.

About pond fish farming, because of the problem of fish fry, so the feed can be fed relatively small food is better, such as aquatic insects, plankton, earthworms, small duckweed and mashed young grass can be fed In fact, fish fry are relatively easy to raise, general fish feed is OK, there is no kind of feed is particularly good, which feed is particularly bad, so to say.

What can be used to fertilize the water.

The reasons why the water in the fish pond is not fertilized are as follows: low water temperature, rainy days, insufficient nutrients in the water body, weak light, and turbid water, so you can start from the above reasons.

If the fish pond is relatively small, you can improve the problem by building a plastic shed, and you can also buy something to strengthen the water fertilizer of the fish pond for water nutrient supplementation.

There are three types of feed that can be fed to fish farming, which are animal feed, plant feed and synthetic feed. Among them, animal feed includes water, rotifers, daphnia, earthworms, maggots, etc., and plant feed in addition to aquatic weeds and algae, you can also choose some vegetables, but you can only feed them after scalding and cutting them into cubes. Synthetic feeds are flakes and pellets, the former for upper and middle pelagic fish, and the latter for demersal fish.

Animal feed is preferred for fish farming. This feed has a high protein content, which not only the fish love to eat, but also helps to grow. The usual animal feeds include water flow, rotifers, daphnia, water earthworms, fly maggots, harvest shrimp, silkworm pupae and so on.

Some of these foods do not need to be processed and can be fed directly, while others should be broken and fed, and the amount should not be too large, otherwise it is easy to spoil the water.

Plant-based feeds are more suitable for some herbivorous fish, and for omnivorous fish, it is also an optional food. In addition to aquatic plants and algae, common plant-based feeds also include vegetables, but they cannot be fed directly to the fish, so they need to be processed and diced after they are blanched, and the size should be controlled to ensure that the fish can swallow. It should be noted that this kind of feed cannot be fed alone, and it is best to use it with some animal feed.

Synthetic feed is a variety of fish food that can be bought on the market, and generally has a detailed ingredient list, which is very helpful for the development of fish, and some can also promote their color. It should be noted that synthetic feed is divided into flakes and pellets, the former will float on the surface of the water and is very suitable for some upper and middle pelagic fish, and the latter will sink and be suitable for some fish that live on the bottom.

Breeding forage fish requires frequent water changes to create feeding places with large water bodies. Maintain the temperature of the conservation environment, which can lead to health risks to forage fish.

Second, the key points for novice fish farming

1. If you decide to raise fish, don't rush to buy fish tanks and equipment, but first go to various aquarium forums to dive and make up for the basic knowledge of fish farming.

2. With a preliminary understanding of fish farming, you can open a tank to raise water. You can follow the steps in the forum to open the cylinder, burst oxygen, open filtration 24 hours a day, add trillions of nitrification and fine sensitive bacteria (not necessary), etc., and the time to raise water depends on how little patience you have.

3. The daily maintenance is mainly feeding and changing the water, it is said that the fish are raised first, and the hard problem of filtration is put aside, and the main reason for the deterioration of water quality is in the method of changing water and feeding.

1. Polyculture fish feed formula: generally can be used 40% rice bran, 38% bran, 10% bean round pants cake, 10% fish meal, 2% yeast powder, feed coefficient is, at the same time can also add some green feed, feed coefficient is appropriate, can be reasonably prepared according to the actual breeding situation, such as the size of the breeding scale and the different varieties of breeding to decide, generally this formula is suitable for most polyculture fish.

2. Daily feeding amount: 80% of the average daily feeding in the first half of each month from March to August, the average daily feeding in the middle of the month, 120% of the average daily feeding in the second half of the month, starting from September, 120 of the average daily feeding in the first half of the month, the average daily average in the middle of the month, and 80% of the average daily fibrillation in the second half of the month.

What fish is best to keep is suitable for polyculture

1. Cavity prudence is based on the same water quality requirements for polyculture

The water quality requirements of different fish species need to be considered when polyculture fish, and it is recommended to select fish with similar water quality requirements for polyculture. For example, freshwater fish and marine fish should not be polycultured, while goldfish, koi, etc. are freshwater fish and can be raised together. In addition, fish with large body shapes also need to be careful, for example, fish that eat a large number of small fish and small fish should not be polycultured to avoid predation.

It is recommended to polyculture fish with similar water quality, such as the white series: Baiyun Mountain, White King Kong. Red series: different species of red fish such as tall legs pearls, purple crucian carp, red navel carp, red fireballs, etc.

2. Consider the aggression and character of the fish

When choosing polyculture fish, it is important to pay attention to whether the aggression and personality of the fish affect each other. Some of the more ferocious or aggressive fish, such as large carnivorous fish, are not suitable for polyculture with other fish. Some relatively mild fish, such as Nile tilapia and African cichlid, can be polycultured with other fish.

Depending on the different characteristics of aggression and personality, suitable fish can be selected for polyculture, such as carp, koi, grass carp, etc.

3. Polyculture of herbivorous fish and carnivorous fish

Polyculture of herbivorous and carnivorous fish is also common, as it can maintain proper water quality and avoid predation and accumulation of similar species. When choosing herbivorous fish and carnivorous fish, it is also necessary to pay attention to the fact that fish with large body size differences are not suitable for polyculture.

When polyculture of herbivorous fish and carnivorous fish, you can choose some herbivorous fish such as koi, carp, etc., and then choose some carnivorous fish such as Napoleon wrasse, red arowana, etc.

4. Polyculture of small fish and large fish

Small and large fish can also be polycultured, but they should be selected according to the size of the fish, and there should not be too much difference between the front and back. Due to their small size and small range of activity, small fish are suitable for polyculture with fish of the same size. Larger fish require more space and suitable load water quality, so polyculture with larger fish is recommended.

Small and large fish can choose from Sakura Arowana, Angel Fish, Betta Fish, Wu Sui, etc.

To sum up, polyculture fish must pay attention to the water quality requirements, aggression and personality, feeding habits and other aspects of different fish, and choose the right fish for polyculture, so as to effectively avoid predation and killing events and maintain the stability of the ecological environment in the aquarium.
