Requirements and matters needing attention of compound feed for silver carp

Silver carp is a kind of fish, it is different from crucian carp and carp, the head of silver carp is larger, so its nutritional value is mostly on its head, and we all know that the nutritional value of fish is very rich, and eating fish contributes to the development of the brain, so it is best for children to eat fish once a week.

What is silver carp?

Silver carp (scientific name: Aristichthys nobilis) is also called silver carp, fat head fish, Baotou fish, big head fish, black silver carp, hemp silver carp, also called male fish. It's a kind of freshwater fish. It has the elegant name of "scavenger in the water", and it is one of the four big fish in China. It looks like silver carp and is flattened on the side. The head is large and wide, and the mouth is wide and slightly warped. The eye position is low. Silver carp grows in freshwater lakes, rivers, reservoirs and ponds. Mostly distributed in the middle and upper layers of the water. It is a fish endemic to China. It is widely distributed in China. It is one of the main objects of pond culture and reservoir fishery, and its economic value is high. Edible, can improve the IQ of the human body, enhance memory, supplement nutrition, delay aging.

Requirements of compound feed for silver carp

After domestication, silver carp (silver carp) can eat formula feed. After 0.5 hours of feeding, some researchers dissected the intestines of silver carp and found that the intestinal filling degree was mostly between 4 and 5, and most of them were artificial compound feed, and only a few of them were large zooplankton. When raising silver carp alone or mainly, it is generally necessary to feed compound feed in order to improve the growth rate and yield of silver carp. The main culture of silver carp is generally not suitable with carp, grass carp and other fish with strong predation ability, but with silver carp and crucian carp is relatively better. When silver carp and silver carp are bred together in various ponds, because the feed powder fed to other fish is a good source of food, it is generally no longer fed separately.

After domestication, silver carp is mainly fed on the surface of the water body, the head is above the water surface, swims slowly around the food farm and actively ingest compound feed, which requires that the feed should have better floatability in the water. In general, the particle size of pellet feed is suitable between 0.3~0.8mm. At present, the commodities on the market are usually powder. The utilization rate of feed with strong floatability can reach 90%.

Matters needing attention in feeding

Special attention should be paid to avoiding waste. When throwing hands, feed a small number of times, each time the speed of feeding slows down. In cage culture, feed is generally packed in cloth bags to train fish to touch cloth bags so as to obtain sufficient food according to the needs of fish bodies. The best feeding point in the reservoir area is in the upwind, quiet, and the water is not too deep. Make a basket with bamboo and sprinkle the powder in the center of the basket. If necessary, you can also sprinkle the powder after adding water, but pay attention to mixing water evenly.

The value of silver carp

1. Edible value of silver carp

The brain of bighead carp contains a kind of fish oil needed by the human body, and the fish oil is rich in polyunsaturated fatty acids, which is an essential nutrient for the human body, which can maintain, improve and improve brain function. The meat under the fish gills is transparent and gelatinous, with plenty of water and rich in collagen, which can resist aging and repair the body's cells and tissues.

II. Nutritional value of silver carp

Bighead carp is a kind of fish with high protein, low fat and low cholesterol. Every 100 grams of bighead carp contains 15.3 grams of protein and 0.9 grams of fat. In addition, bighead carp also contain vitamin B2, vitamin C, calcium, phosphorus, iron and other nutrients. Bighead carp has a protective effect on cardiovascular system. Pituitrin, which is rich in phospholipids and improves memory, especially the brain pulp is very high. It can warm the stomach, dispel vertigo, benefit IQ, help memory, delay aging and moisturize the skin.

In order to obtain high quality and yield of silver carp in the process of culture, feed is essential, but there are still many points that need to be paid attention to in the process of feed feeding. therefore, mastering some feed feeding methods and techniques is also very helpful to improve the yield of fish.
