1. What industry is suitable for starting a business now? What are the benefits of ryegrass fish farming?

Ryegrass is not an ideal forage variety for fish farming. Ryegrass is forage for winter, but fish will not eat grass in winter when the water temperature is low.

The current high-yield, perennial forage series used in fish farming include:

Moisturizing grass, sweet elephant grass, royal bamboo grass, etc.

2. What are the green fodders for fish farming?

Select green fodder plant varieties. Currently, the more common high-quality green fodder plants include ryegrass, Sudan grass, elephant grass, pine grass, duckweed, etc. Different green fodders have different nutritional values. Different high-quality green fodders should be selected at different growth and development stages of fish. In production, it can be selected according to the difficulty of the green fodder source and the needs of fish growth and development. Timely mowing of green fodder plants contains different nutrients at different growth stages. Green fodder plants that are not mowed in time often increase the degree of lignification, resulting in a significant decrease in the utilization rate of forage by fish. For example, general grasses should be mowed at heading, and leguminous grasses should be mowed at the beginning of flowering. The mowed green fodder plants should be fed in time. If they are left for too long, not only will the nutrients be easily lost, but the palatability will also deteriorate.

Processing and conditioning: The green fodder plants can be directly fed to the farmed fish after cutting. If used for seed cultivation, the green fodder should be chopped or pulped. Fermentation can also be used to improve the palatability and utilization rate of green fodder plants. For example, water peanuts have poor palatability and fish cannot digest and absorb them directly, but after fermentation, fish can eat them.

Strengthen the prevention and control of fish diseases. Green fodder plants are mainly used by herbivorous fish, which are prone to disease. Therefore, attention should be paid to the disinfection of water bodies and the use of medicated bait to prevent fish diseases, and the feeding amount, feeding time and frequency should be reasonably arranged.

Insist on combining green and concentrated feed. Although green feed is more comprehensive in nutrition, its nutrient concentration is low and it is difficult to meet the needs of rapid growth of fish. A more feasible way is to combine green and concentrated feed to supplement each other.

When arable land is insufficient, green fodder plants should be planted on the edge of the pond, the bank, the embankment, etc. For pond fish farming, green manure, ryegrass, etc. can be planted in the idle pond in winter to achieve the combination of planting and breeding, so as to achieve high yield, low consumption, high efficiency and low cost.

Hello, the common green fodders are ryegrass and Sudan grass.

In fish farming, giant fungus grass with high crude protein content, good palatability and high yield can be used as green feed.

Giant Juncao is a perennial, high-yield, high-quality forage grass with thick leaves, soft and juicy texture, rich and balanced nutrition, and easy digestion.

Giant fungus grass has a high crude protein content and is suitable for pigs, cattle, sheep, horses, rabbits, geese, ducks, chickens, deer, elephants, fish and other livestock and aquatic animals.

High quality green fodder.

Plants are mostly

Chinese Cabbage

3. What grass species to use for fish farming

Sudan grass, ryegrass, Mexican corn grass, pennisetum, syngonium, nephrolepis, chicory, etc.

The characteristic and core of Chinese pond fish farming technology is to raise fish of different species and ages or of the same species and ages but with different habitats and feeding habits in the same water body. The fishes to be mixed should have related habits and similar requirements for water quality and water temperature (during the growing season). The ideal fishes for mixed culture include silver carp, bighead carp (upper layer fish), grass carp, bream (middle layer fish), carp, crucian carp, dace, black carp (bottom layer fish), etc.

Mixing fish that live in different water layers can make full use of water space.

Compared with traditional farming, the density of stocked fish can be increased significantly. The feces of grass carp and black carp are not only fertilizers for cultivating plankton, but also provide a large amount of organic debris and breeding bacteria for silver carp and bighead carp to filter feed; carp, dace and crucian carp can remove residual bait and improve water quality. It can not only make full use of water and increase production, but also recycle bait and improve water quality.

Suitable forage grasses for fish feeding include Sudan grass, ryegrass, Mexican corn grass, Pennisetum, Syngonium, Solanum oleraceum, Chicory, etc. The growth period of Sudan grass is 100-140 days, with a fresh grass yield of 4,000-6,000 kg per mu, and a sowing rate of 2-2.5 kg per mu; Rye grass can be divided into perennial and annual ryegrass, with a fresh grass yield of 3,000-7,000 kg per mu, and the sowing rate depends on the soil fertility. The soil is divided into three grades: good, medium, and poor, with 0.6, 0.7, and 0.8 kg per 0.067 hectare; Mexican corn grass is an annual herb, with a stem and leaf yield of 10,000-30,000 kg per mu, and 750 grams of seeds per mu.

Water Peanut

1. Sudan grass: It is a plant suitable for growing in the southern region. It grows fast and has good regeneration ability. It can be used as fish feed and digested by them. And because of its good nutritional value, after being eaten by fish, it can grow a good body and the meat will be much more tender.

2. Eyebright: It is a biennial aquatic plant. It is used as forage grass for fish farming and can be directly cultivated in water. Its taste and nutrition are very suitable for fish consumption. In a good environment, it can grow very fast and has a high yield. It is a very high-quality forage grass.

3. Sweet elephant grass: Sweet elephant grass has a high protein content and a great taste. When feeding it to fish, its stems and leaves can be chopped short and finely chopped. It is easy to digest and can accelerate the growth of fish.
