Aquaculture in China covers an area of 8465 thousand hectares, of which 27.38% is marine aquaculture and 72.62% is freshwater aquaculture. There are 32,000 aquaculture farms in China with an area of 10 million hectares, and the aquaculture industry provides a huge market demand for water quality monitoring, such as temperature, salinity, PH value, dissolved oxygen, and aquatic observation, such as the observation of the growth state of fish, shellfish, sea cucumbers, etc.
In 2020, The POET used PX-260AUV with side-scan sonar to investigate artificial reefs offshore.
In 2020, a PX-100ROV was used to observe an artificial reef.
During cage culture, the mesh is often attached and bred by marine phytoplankton.Microscopic attachments not only affect the exchange of water inside and outside the net tank ,but also increase the pressure of the external water flow on the net tank, which leads to the damage of the net tank structure, more seriously, if the oysters and other hard-shelled shellfish are attached, it will lead to a sharp increase in the weight of the net coat, which fundamentally destroys the net tank mesh and may produce a major incident of fish escape. Therefore, the focus of netting culture is to ensure the cleanliness of the netting in order to ensure the natural flow of seawater between the aquaculture area and the external seawater, so that the fish in the aquaculture area are in the best living environment. The netting cleaning robot is the most effective cleaning tool .
