1. Moss generally grows under clean water, so it will not be polluted. It is a natural green and healthy food.
2. Moss is nutritious and helpful to human health.
Moss adheres to the surface of an object and spreads and grows, so it is also called moss coat. Moss is green and as thin as silk. It can be attached to rocks, pools, roofs, decaying walls, wetlands and other dark, damp and inaccessible places, just like hair. This is a very humble but very interesting plant.

Hazards of moss:
Moss competes with aquatic plants and other algae for nutrients, which consumes too much water nutrients, destroys the normal material metabolism of ponds and makes the aquaculture water thinner. Consequences of thin water quality: the growth of aquatic plants is inhibited; The periodic growth of plankton is destroyed, which leads to the imbalance of algae in the water ... These will affect the normal growth of crayfish, crabs and fish.
A large number of cultured water bodies with moss are clear and transparent. The direct sunlight in the pond increases the stress response of crayfish, crabs and fish. Long-term stress reaction can easily lead to the decline of immunity of cultured animals and lead to pathological changes.
Moss grows and breeds in large numbers, hanging in the water like a "tight encirclement", and it is easy to entangle crayfish, crabs and fish. The entangled crayfish, crabs and fish can hardly struggle out, and they can only starve to death or be exhausted.
Dead moss is blown to the corner of the pond with the wind or rotted at the bottom of the pond, which not only gives off stench, but also consumes dissolved oxygen in the water during decomposition, producing many toxic and harmful substances, which leads to the decrease of dissolved oxygen in the aquaculture water and the increase of harmful substances such as ammonia nitrogen, nitrite and hydrogen sulfide, which makes the water quality worse and leads to the death of crayfish, crabs and fish due to hypoxia poisoning, which is harmful to healthy aquaculture.
