High temperature season has come, many farmers will choose to build shade net to spend the summer. During the day, the shading net can effectively block the light, prevent the sea cucumber pool from heating too fast, and play a role in cooling. In the same way, the shading network will also block the wind and affect the efficiency of natural wind oxygen, and at night, the shading network will also block the heat emission of the pool water, resulting in water stratification and the aggravation of oxygen deficiency at the pool bottom. We often ignore the fact that more than 80% of the oxygen in the water comes from the photosynthesis of algae and moss. When we visit our customers, we often hear that some bosses pull up the shade net, because of improper management, the sea cucumber has an accident before the high temperature. Therefore, the pond management after shading net is a new management mode.
When the shading net is installed in the sea cucumber pond, the light note of the sea cucumber pond will be affected, the photosynthesis of algae and moss will be weakened, and the oxygen production capacity will be reduced; the light will be weakened, and the flagellate algae that like weak light will be the main species in the water body, with strong oxygen production capacity in the daytime and large oxygen consumption in the evening; the organic matter such as dead algae and moss at the bottom of the pond will continue to be heated by anaerobic fermentation, which will increase the oxygen consumption at the bottom of the pond; the natural wind will change Small, the flow of water becomes poor, and the self purification capacity of water body becomes weak, so after installing the shading network, it is a new management method.
