1, provide food.

The fresh aquatic plants are rich in nutrients, convenient in intake, good in palatability, and free of pollution. They are natural foods such as river crabs, green prawns and herbivorous fishes, such as Hydrilla verticillata, Vallisneria, Hydratogenesis. The stems, leaves and roots of aquatic plants contain nutrients such as protein, fat, and vitamins, as well as calcium, phosphorus, crude fiber and various trace elements, and a large amount of active substances. The water grass provides an excellent place for the reproduction and growth of zooplankton, benthic and aquatic insects in the water. Its biomass is 1.5-2 times that of the grassless area, and these are the animals that are preferred by fish, crabs and crabs. The bait and aquatic grass also play an indirect role in producing natural food.

2. Provide sheltered habitats.

This is more pronounced in shrimp and crab farming. The shrimps and crabs have weak swimming ability and can only swim for a short time. They generally prefer to stay on the bottom of the pool or on the wall of the pool and other climbing objects to crawl and crawl, fundamentally limiting their own distribution area. The aquatic plants can separate the water bodies of the ponds. Innumerable small spaces not only provide a good habitat and playful environment for shrimps and crabs, which facilitates their better growth, but also greatly expands the breeding space, thereby increasing the stocking volume of seedlings per unit area of ​​the pond and overcoming the original due to its own There are few distribution areas and the problem of limiting production. More importantly, aquatic plants can be used as a place of attachment and concealment. The growth mode of shrimps and crabs is the growth of the moltings. The cultivation of the shrimps should undergo repeated molting. During the molting period, it is easy to encounter the invasion of enemy organisms. The aquatic plants can help the soft shell crabs and crabs to escape the enemy and can greatly increase the survival rate. To achieve the effect of increasing production.

3. Absorb and decompose organic substances.

Fish, shrimp and crabs all like to live in fresh water and oxygen-rich waters. The residual artificial bait and metabolites of water-producing animals are decomposed into nitrates through reactions such as ammoniation and nitrification. If oxygen is lacking, the reaction is incomplete, and harmful substances such as hydrogen sulfide, ammonia, and nitrite are also produced in the water. The existence of these substances has great harm to the survival and growth of fish, shrimp, crabs, and is more likely to cause diseases, leading to production failures and causing economic losses to farmers. The growth of aquatic weeds can absorb large amounts of harmful ammonia nitrogen, carbon dioxide, inorganic salts, and remaining feedstuff dissolved materials and some organic decomposition products that are continuously generated in water, effectively preventing eutrophication of water bodies, purifying water quality, and improving bottom quality. The water body is fresh, the PH value is stabilized, and the transparency of the water body plays an important role.

4, prevention and treatment.

Waterweed itself contains many medicinal ingredients, such as a large number of alkaloids, organic acids, aminopurines, pyrimidines and other organic substances, all have the functions of sterilization, anti-inflammatory, detoxification, swelling, hemostasis, and strong, and are natural Chinese herbal medicines in healthy breeding. Has a non-negligible pharmacological effect. It is understood that the incidence of shrimps and crabs in ponds rich in aquatic plants is about 40% lower than that of ponds without aquatic plants.

In summary, aquatic weeds play an active role in the healthy culture of fish, shrimp and crabs, but it does not mean that the more weeds, the better. If there are too many emergent plants in the pond, the coverage area is too large, which will affect the movement of farm animals through the water, relatively reducing the living space and affecting normal growth, which is not conducive to the survival and growth of fish, shrimp and crabs. Experiments have shown that when the fast-growing aquatic plants reach a certain limit, self-screening effects are easily shielded on the water surface, and the environment is constricted. At this time, the growth of water grass and the ability of water purification are stagnated and slowed down. In addition, excessive decomposition of aquatic plants and dead leaves in the water to produce carbon dioxide and organic acids will affect water quality, making the water's PH value low, which is not conducive to fish, shrimp and crabs.
