At present, the existing underwater biological shooting method in China mostly uses a camera to continuously shoot, and no biological image occupies a large data storage space. Meanwhile, due to the fact that continuous shooting is large in power consumption, the shooting device is often fixed in a sustainable power supply area. However, most of the field areas are not provided with power facilities, so that the working time of the shooting system or the working area is limited, and the requirement of carrying out long-term in-situ monitoring on aquatic organisms in the field cannot be met.

Most underwater equipment such as unmanned ships need personnel on duty, are difficult to realize long-time underwater monitoring, and the underwater equipment who adopts simultaneously is easily disturbing fish in the removal in-process.
CN 110873555A discloses a system and method for observing underwater living things, which collects image information of fish through a light curtain scanning array. When the device is used, the fish image information can be obtained only when the fish passes through a specific channel, so that the moving range of the fish is limited, and the normal living behavior of the fish is difficult to shoot.
