1. What do silver carp eat and how to breed them

Silver carp is a filter-feeding freshwater fish that mainly feeds on zooplankton. From the fry to the adult stage, it mainly feeds on zooplankton (rotifers, cladocerans, copepods, etc.). When it is more than 1.5 cm long, it also feeds on phytoplankton, which is a typical plankton-feeding fish. When cultivated artificially, silver carp also eats artificial feeds such as bean cakes, bran, rice bran, distiller's grains, and poultry and livestock feces (chicken manure, cow manure, etc.). Artificial micro-granular compound feed can also meet the silver carp's food needs.

1. What do silver carp eat?

1. Silver carp mainly feeds on zooplankton. From the fry to the adult stage, it mainly feeds on zooplankton (rotifers, cladocerans, copepods, etc.). When it is more than 1.5 cm long, it also feeds on phytoplankton. It is a typical fish that feeds on plankton. When it is artificially cultivated, silver carp also eats artificial feeds such as bean cakes, bran, rice bran, distiller's grains, as well as poultry and livestock feces (chicken manure, cow manure, etc.), and prefers to eat artificial micro-granular compound feeds.

2. Silver carp is a mild filter-feeding fish. It does not compete for food or snatch food. When other fish are competing for food, it usually just waits and watches from the outside and does not enter the feeding table to grab food. Therefore, it can only be raised alone when fed with feed, and cannot be mixed with other feeding fish. Feeding should adhere to the "four fixed" principles of fixed quality, fixed time, fixed location, and fixed quantity. Feed according to the feeding rhythm of the fish species, and the feed cannot be too simple. Its feeding intensity varies with the season, and is generally higher from April to October each year.

2. How to breed silver carp

1. Build a fish pond

If you want to breed silver carp in large quantities, you must first build a suitable fish pond. The fish pond should be a certain distance away from the city, and the size can be determined according to the scale of breeding. The larger the fish pond, the better, preferably between 4-8 mu, with a water depth of more than 2 meters, and organic fertilizer should be applied for cultivation before stocking the fry, so as to provide nutrients for the silver carp and ensure its normal growth. Organic fertilizer can be selected from decomposed animal manure or cake fertilizer, but the fertilizer should be appropriate and the concentration should not be too high.

2. Stocking fish fry

To breed silver carp, the fry must be released. There are two types of release: single culture and mixed culture. Mixed culture means breeding silver carp with other fish. This can maintain the environmental balance in the fish pond, so that all types of fish can grow normally and create higher economic benefits. Silver carp is most suitable for mixed culture with carp, bighead carp and other fish.

3. Daily management

Silver carp has the habit of preying on plankton, so during the breeding period, the pond water must be kept fertile and the number of plankton must be high, so as to provide sufficient food for silver carp. At the same time, the pond water must be changed frequently to ensure the cleanliness of the water. In addition, during the breeding period of silver carp, when artificial feed is added, it must be fed regularly and the feed cannot be too single, only in this way can the utilization rate of feed be improved.

4. Winter management

The temperature drops significantly in late autumn and early winter. If you want silver carp to spend the winter safely, silver carp will hardly eat when the temperature drops below 10 degrees. At this time, you must gather all the silver carp in the pond and stock them in a deeper pond so that the temperature will not be so cold. If you don't have the conditions, you need to clear out all the silver carp and sell them, and then start raising them from fry next year.

2. Can grass carp, silver carp and bighead carp eat feed and freshwater crayfish?

Freshwater crayfish can be mixed with silver carp and bighead carp, because the pond for raising freshwater crayfish needs to be planted with aquatic plants. The area of ​​aquatic plants such as Hydrilla verticillata, Potamogeton oleraceus, and Elodea nutans should account for 2/3 of the shrimp pond area. At the same time, set up nets, bamboo tubes, plastic tubes, etc. to provide a habitat, molting, and hiding place for crayfish. Grass carp will eat these aquatic plants. So it cannot be mixed with grass carp. Silver carp and bighead carp can eat granular feed.

You can refer to the following information:

It is possible to eat summer slices and spring flowers of grass carp.

Grass carp is a herbivorous fish and does not eat other organisms. Silver carp and bighead carp are both surface pelagic fish, mainly feeding on plankton, and have even less impact on crayfish.

Grass carp can be fed with special grass carp feed, while silver carp and bighead carp are mainly fed by increasing the nitrogen content of the water to cultivate plankton.

Additional answer: Sure.

3. How much food do 5,000 silver carp eat?

6 jin.

Assuming that 10 silver carp consume 0.012 catties of feed, 5,000 silver carp will eat 6 catties of feed.

Bighead carp, a carp of the family Cyprinidae in the order Cypriniformes, is also known as silver carp, fathead fish, Baotou fish, bighead fish, black carp, bighead carp, and male fish.

4. What kind of feed do bighead carp and grass carp eat?

Grass carp is a typical herbivorous fish. It starts to eat grass when the young fish is 5cm long. For grass carp weighing more than 250g, each fish can eat 125-180g of grass per day. If it is cultivated, it can be fed with grass and special grass carp complete feed. For bighead carp, the feeding method is to use natural bait as the main feed and compound feed as the auxiliary feed. Organic fertilizer or inorganic fertilizer can be applied to cultivate plankton for bighead carp to eat. On this basis, compound feed is used as a beneficial supplement for fish seed cultivation. In high-yield fish ponds, the cultivation method of compound feed as the main feed and natural bait as the auxiliary feed can also be adopted. According to the nutritional needs of bighead carp, feed complete feed, and apply appropriate fertilizer to cultivate natural bait. The cultivation of complete feed has a good effect. Powdered or crushed feed can be used. According to the nutritional needs of bighead carp, it is also effective to mix a variety of feeds according to the formula and feed the fish. The feed should be kept fresh, and moldy feed should not be used.

There are special compound feeds for grass carp, which are available in feed factories.

Bighead fish generally do not need to be fed, just fertilize the water to let them eat zooplankton. If you must feed them intensively, you can feed them powder, generally yellow powder, second powder, bran powder, etc.

The feed is good!

However, it is too expensive to raise slow-growing fish such as bighead carp and grass carp. In Guangdong, ryegrass is usually grown near fish ponds and is suitable for planting in cold regions. The most important thing is that it is low-cost and does not require much care!

Hope you make a lot of money!

There are many feeds specially made for grass carp on the market.

I suggest you consult your agent.

Here is a suggestion for you. Some manufacturers can provide a payment-after-use method, which means they give you the materials first, and then pay you when your fish grow big enough to sell!

I used to be the sales manager of Xingye Doctor. Our company’s feed is very good, with a high feed-to-meat ratio. I hope you have a chance to try it!
