Information and analytical management system for fish protection structures of water intakes: architecture and technological implementation

The presence of information gaps in the hierarchy of interaction between the Federal Agency for Fisheries (Rosrybolovstvo), territorial authorities and owners or organizations operating water intakes is one of the problems of managing fish protection structures (FPS). The purpose of the work is to develop the concept of an information and analytical system (IAS) for managing fish protection structures of water intakes, including the architecture of the system, a hierarchical management scheme, a description of software and technological components, and, in particular, the use of neural network models for processing unstructured data. The architecture of the system is proposed, based on a three-level structure (data layer, analytical core, interaction interfaces), providing end-to-end monitoring of the functioning of fish protection facilities without additional equipment. As an innovative component, the integration of the large Gemma 3 language model (27 billion parameters) has been implemented for automated recognition of «raw» documents and unified data entry of operating organizations into a single database. The development methodology includes integration with existing information sources (hydrological posts, ichthyological stations, IoT sensors). The system is adapted to the operating conditions of water bodies: it supports heterogeneous input data formats, operates in a hybrid mode (automatic recommendations with the possibility of manual redefinition) and does not require replacement of the existing infrastructure. The introduction of IAS reduces the reaction time to changes in hydrological conditions from several days to several hours, minimizes operational risks caused by manual input of information, and optimizes maintenance costs for fish protection facilities.
