What grass is best to plant for raising grass carp? Recommendations for high-quality forage grass suitable for grass carp

SummaryFor raising grass carp, planting ryegrass and Sudan grass is best. Ryegrass has strong adaptability to various soils, is easy to grow, and can promptly provide the amount of feed needed by grass carp. Sudan grass has strong drought resistance and can grow vigorously even in hot summers and arid regions. This is also the main forage that provides feed for grass carp.

Grass carp mainly eat duckweed, aquatic plants, and early grass, etc. For every 0.5 kg of growth, a grass carp needs to eat 90 jin of aquatic plants or 40 jin of early grass. Grass carp have a certain selectivity for early grass; generally, they prefer grasses with net-like veins over those with parallel veins. However, whether aquatic plants or early grass, tender and fresh ones should be the main choice. Tender grass has more protein and less cellulose, making it easier for the fish to digest after eating.

The following points should be noted when feeding grass carp with grass

1. Feed more fresh and tender forage, because it is rich in nutrients and low in cellulose, making it easier for the fish to digest after eating, and it can also make the fish grow quickly and suffer fewer diseases. However, fresh and tender forage is limited while the fish have a large food intake, so it is best to feed artificially planted ryegrass, Sudan grass, and wild long-leaf tender grass. Round-leaf forage with net-like veins is not suitable for feeding. The feeding situation of grass carp should be observed promptly; feeding more of the forage they like plays an important role in the growth and development of grass carp.

2. If a grass carp eats 30 jin of aquatic plants grown on land, it can gain 2 jin of meat. If it eats aquatic plants grown in water, it needs to eat more than 100 jin of forage to gain 2 jin of meat. Therefore, the feeding of aquatic water plants should be reduced.

3. During the juvenile stage, grass carp have small mouths, so coarse and hard forage should not be fed. Small duckweed should be the main food, or fresh tender grass can be chopped up and fed. As the fish grow larger, their mouths also increase in size. At this time, conventional forage can be fed to ensure the feed intake of grass carp.

4. The feeding method for grass carp should be appropriate: feed regularly, in sufficient amount, and evenly every day. The forage should be spread evenly so the fish can eat their fill and eat well, thereby improving the breeding effect. According to the weather, water quality, and fish activity, the feeding amount needs to be adjusted in a timely manner. Stale or moldy forage must not be fed, so as to avoid the fish becoming infected with disease and dying.
