Restoration of fish migration paths on the Manych River is the first stage of a major program to create a “Natural Park“ Donskoy Sturgeon Park ”in the Rostov Region. The main objective of the first stage is to develop systems for collecting and processing information and install them on the input and output channels of fish migration.
The problem or task
Main functions performed by developing a set:
- Autonomous power supply of the complexes at the point of 3.1 and 3.2 and ensuring their functioning in all weather conditions typical of this region.
- Ensuring the uninterrupted operation of the equipment and software of the 1 and 4 complexes in all weather conditions, providing the systems of the complexes with protective boxes and / or heat-resistant, waterproof boxes.
- Ensuring security alarm systems and video surveillance for continuous protection against the possibility of theft and vandalism.
- Counting the number of fish leaving the river. Manych and entering the channel and vice versa. Classification (that is, the ratio of the size of the fish to its quantity) by weight and size parameters, followed by classification by type of fish and weight and size parameters.
- Continuous monitoring of water quality and composition, temperature, water flow rate and temperature at points 1 and 4. Monitoring is carried out at several points in the water column (different depths), including the bottom and the water surface.
- Continuous collection of information from power supply complexes, object protection systems, fish monitoring and water monitoring, transfer of the received information to a centralized server via wired / wireless secure communication channels. The server must be able to access the accumulated information via the global Internet to view and analyze reports required by users with different levels of access. Including public access.
- The system should be able to easily expand the number of monitoring points to increase the coverage of the Donskoy sturgeon network.
The area of work performed for the first phase of the project is the territory shown in Figure 2. The first section on which the installation and field testing of the system is planned is the section between the points 3.1 and 3.2 (Figure 1). In general, as mentioned above, the system consists of 4-x main nodes:
- Node autonomous or mixed energy.
- Guard node.
- Site monitoring of water and atmosphere.
- The node monitoring and analysis of fish migration.
- collection unit, analyzing and reporting information obtained complexes 1-4.
Each point of the system consists of typical nodes. The principal difference of the points is the width of the water channel (under the channel here is meant any kind of water body). The cost of the registration system and the complexity of the installation of the recording sensors essentially depend on the width of the channel. Also, the accuracy of biomass registration and its classification depend on the cost of the initial recording modules. In this project, the system starts to register an object from 5 cm in length or more and classifies by size and belonging to a particular kind. The accuracy of registration is very high and is + 1%. It is possible to install systems with reduced accuracy (not lower than + 10%) and lack of classification by type.
Further, the composition of each node is described in more detail and its preliminary estimate of the project cost for two points with a channel width of no more than 10 meters and a depth of no more than 2,5 meters is presented.
