1. What does silver carp eat?

Silver carp is the common name for freshwater fish of the genus Bighead carp in the family Cyprinidae. Its scientific name is bighead carp, also known as black carp, bighead carp, and bighead carp. It is widely distributed throughout the country, especially in the water systems south of the Yellow River. Common individuals weigh 5 to 10 kilograms, and the largest individuals can reach 40 to 50 kilograms. Let’s take a look at what foods silver carp likes to eat the most!

1. Discussion on fish species

Silver carp is the common name for freshwater fish of the genus Bighead carp in the family Cyprinidae. Its scientific name is bighead carp, also known as black carp, fathead carp, bighead carp, and bighead carp. It plays an important role in my country's freshwater aquaculture. Together with grass carp, black carp and bighead carp, it is known as the "four major carps". Together with silver carp, it is collectively called "silver carp and bighead carp". Common individuals are generally 5 to 10 kilograms, and the largest individuals can reach 40 to 50 kilograms.

2. Habitat

Silver carp is a pelagic fish, which usually moves in the upper and middle layers of water bodies. In winter, it swims to deep water areas to hibernate. Juveniles and immature individuals are often fattened in lakes along rivers and affiliated water bodies. The optimal survival temperature is 25-30℃, and the critical feeding temperature is 13-38℃. As long as the water temperature is higher than 13℃ and lower than 38℃, it can maintain a certain feeding enthusiasm.

3. Food habits

Silver carp is a typical filter-feeding fish. It relies on the special structure of its gills to filter out zooplankton such as rotifers, cladocerans, and copepods. It also eats some phytoplankton such as diatoms and cyanobacteria. Summer is the peak feeding season for silver carp, and it is most interested in smelly and sour foods. When artificially bred, it is often fed with bean dregs powder, bran, rice bran, soybean meal, and compound micro-granular feed.

4. Commonly used baits

1. Natural bait: Natural bait can be used to fish for bighead carp. Although bighead carp is a typical filter-feeding fish, it is very interested in smelly food and has a good appetite for sour food, such as distiller's grains, fermented rice, and sour and smelly food.

2. Commercial baits: Commercial baits can be used to catch bighead carp, such as the Crazy Killing Silver Carp and Bighead Carp under the Fishing King, the Golden Edition Floating Fishing Silver Carp and Bighead Carp under the Wuhan Tianyuan, the Unified Exploding Silver Carp and Bighead Carp under the Dragon King Hate, the One-Touch Silver Carp and Bighead Carp under the Hua Shi, and the Fighting Silver Carp under the North and South.

3. Homemade bait: You can use homemade bait to fish bighead carp. In fact, corn flour, flour, soybean flour, wheat bran, rice bran, etc. can be used to make bighead carp bait. In order to enhance the effect of attracting fish, you should also add some koji wine, yogurt, etc. and ferment it to produce a sour smell.

It eats phytoplankton, soy milk, bean dregs powder, bran and rice bran, etc. It prefers artificial micro-particle compound feed and is suitable for breeding in fertile water.

2. What does silver carp eat and how to breed it

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. 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.

3. What do silver carp like to eat? What are the best fish to catch?

First, confirm the activity area, water temperature, and feeding habits of silver carp and how to match bait for fishing. (i) Silver carp is a fish in the upper waters. It likes to swim in groups and seems to be indifferent to external sounds, parabolas, and humans. It is also relatively careless in alertness. For example, if you fish in the nest, the silver carp will return to the nest after a few minutes, unlike carp, which will not come back after a long time. Therefore, silver carp is easy to catch. (ii) The water temperature is not very demanding for silver carp. The temperature difference does not seem to matter. However, high water temperature, low air pressure, hot and humid weather, and no wind are all good times to fish silver carp. As long as you grasp the weather changes and do not fish for carp or crucian carp instead of silver carp or bighead carp, there are opportunities to fish every day. (iii) Silver carp is not very picky about feeding habits. It can be fragrant, sour, smelly, awake, or light. Many anglers do not like it to enter the nest. When you make a nest, silver carp will come soon. A group of silver carp of different sizes will frequently enter the nest, making the bait turbid. In addition, silver carp is a filter-feeding fish, so it won't take long for the bait in the nest to be swept away. So the more we understand it, the better we will be able to deal with it. I suggest that if you want to catch silver carp well, the weather is very important. You should choose; "In the morning, the water surface is foggy, the weather is hot and humid, there is no wind, the water temperature is high, about 26 degrees, the water is fat or thin, and the fishing position is selected; find the confluence, outlet, and bend in the river. Choose a wide water area and water inlet in the fish pond. Sea rod matching group; sea rods above 3.6 meters are suitable for hand-cranked reels of 5000-6000, which should be hard and not easy to have more than 2-3. Line group configuration: 4-5 main lines should be softer, lead weights of 70 grams, running lead fishing method, large floats, large baits, baits to make flying hooks, 8 are better, and the bait ball is 30 cm away from the water surface. The bait is required to disperse quickly, atomize well, and have a strong, sour, and smelly taste. Here are my recipes for silver carp (I) and silver carp (II). For everyone to try. Raw materials: cornmeal, bran, glutinous rice, fermented glutinous rice wine. Requirements: 8 jin of cornmeal + 1.5 jin of bran + 0.05 jin of glutinous rice + 3 jin of fermented glutinous rice wine. Utensils: a sealed pickle jar (clean and disinfect with wine instead). Production method: First, mix 8 jin of cornmeal + 1.5 jin of bran with cold water, squeeze it into steamed buns and steam it in a pot (after boiling) for 20 minutes, then take it out to cool, break it into pieces and put it in the jar, then use glutinous rice to make porridge with a suitable viscosity and pour it into the jar, and finally pour the fermented glutinous rice wine into the jar. Put it in a pot, stir it evenly and seal it. Ferment it in a cool place for 20 days. This is the old soup for bait. Then prepare the same 7 pounds of cornmeal, 3 pounds of bran, 1 pound of soaked granules, and 2 pounds of white flour. Pour out 1/3 of the old soup bait and put it in a plastic bag for use by the waterside. Go to the waterside and use the old soup bait with 7 pounds of cornmeal, 3 pounds of bran, and 1 pound of soaked granules. It is better to dry it. Use white flour to adjust the state of the bait. The taste should be slightly sour and fragrant. Install the fly hook and cast it. After the fish sucks it, the float moves and sinks, and the rod is lifted to catch the fish.

Silver carp feed on plankton throughout their lives. They mainly eat zooplankton in the fry stage, and gradually switch to eating phytoplankton when they are more than 1.5 cm long. They also like to eat grass carp feces and chicken and cow dung. They also eat soy milk, bean dregs powder, bran and rice bran, and they like to eat artificial micro-granular compound feed. They are very interested in sour food and have a good appetite. Silver carp's food has obvious seasonality.

In spring and autumn, in addition to plankton, they also eat a lot of detritus; the lower the water level in summer, the more they eat; in winter, they eat less and move less. It is suitable to be raised in fertile water. The length of the intestine is about 6-10 times the body length. In the process of silver carp breeding, the main silver carp must rely on feed input to achieve high yields. About 50-70% of the output of high-yield ponds is obtained by feeding.

Feed formula: Silver carp feed is best to use full-price compound feed, and formula feed can also be used. Here is a general feed formula for reference. Silver carp feed formula (%): fish meal: 4, soybean meal: 28, rapeseed meal: 10, cottonseed meal: 6, brewer's grains: 5, bran: 6, second flour: 25, rice bran: 12, soybean lecithin: 1, rapeseed oil: 1, calcium dihydrogen phosphate: 1.2, calcium powder: 0.9, mineral additives: 0.5, choline chloride: 0.2, multivitamin additives: 0.2. The nutritional indicators achieved by this formula (%): crude protein 28.5, crude fat 6, crude fiber 7, ash 8, calcium 1, phosphorus 1, lysine 1.5, sulfur-containing amino acids 0.85.

Mix the "sour soup noodles" (70%) that people in rural Northeast China often eat in summer and freshly steamed cornmeal steamed bread (30%) together, dip it in white flour and knead it into a dough of appropriate softness and hardness for hooking.

Bait 2:

The bait left over from fishing that does not contain fish meal or shrimp meal, add some snack residue or sesame paste residue, put it in a plastic bag, seal it, and place it in the sun for more than two weeks. Add some cornmeal steamed bread or white flour when attaching the hook. The longer this bait lasts, the better, and the effect will be better the next year. The author often uses this bait, which does not need to be made specially and saves food.

Bait three:

The ingredients are cornmeal (40%), white flour (10%), glutinous rice flour (5%), cooked bean cake or bean flour (10%), and appropriate amount of brown sugar or white sugar. Mix cornmeal, white flour, glutinous rice flour, and bean cake powder together, scald with boiling water until about 70% cooked, and steam them into steamed bread after cooling; stir-fry wheat bran with slow fire until fragrant; add sesame paste residue when it is fresh, and add it after the dry pieces are softened; crush the snack residue and add it. After mixing the above baits, put them in a plastic bag and put them in the sun. Ferment for two weeks before use. Make more of this bait at one time.

Silver carp and bighead carp bait configuration is divided into main ingredients and auxiliary ingredients. The main ingredients are made by yourself, and the auxiliary ingredients are commercial baits, such as fermented silver carp, crazy bighead carp, etc. Although the main ingredients are hard to make, they can be used for several years after being made once, and a lot of bait money will be saved. I share my recipe with fishing friends. Add 30% corn flour to water and stir, form a ball with your hand, and gently grind it into noodles and steam it for 25 minutes. 30% potatoes are peeled and steamed for 25 minutes. 20% wheat bran is added to water and steamed. 10% leeks are chopped and set aside. 3% Set aside brown sugar5% peel and mash garlic2% sweet wineAdd appropriate amount when you have bean dregsWhen the three main ingredients are steamed, take them out and cool them to 60 degrees, then mix the leek, brown sugar, garlic and sweet wine evenly. After completion, seal each 2 kg package and place it in the sun for three to five days to allow it to ferment naturally. The dried bait can be stored for one year. This is the best main ingredient. Add appropriate amount of commercial bait auxiliary materials when fishing. If you encounter giant silver carp and bighead carp, please add some Wangzhihe stinky tofu for better results.
