The Fishing Cadaster is a database which is kept by the Institute as a public register. The database contains the records of all of the freshwater fisheries.

The Fishing Cadaster was established in the Freshwater Fishing Act of 1976. Its upkeep was taken over by the then Fisheries Research Institute of Ljubljana. At the beginning this was a record of all of the fishing regions that the collected the data on individual fishing regions and fishing families. These fishing regions have been entrusted with the implementation of fisheries management, fish species, fishing management system, fish stocking, angling, and other data important for fishing management.

Fishing Cadaster includes:

Records and information on fishing areas, regions, districts, and exempted waters and the implementation of fisheries management in them;
Records and data on the state of fish populations and
Other relevant data that are the bases for fisheries planning, preparation of various expert research, opinions, measures, and regulations in the field of freshwater fisheries. The goal is to guarantee conservation and the sustainable use of fishery resources.

Fishery logs contain the prescribed information, data processing, and reports. Fishery logs are managed in the Fisheries Cadaster.

The Institute manages, in the Fisheries Cadaster records of: :

  • Fishing areas, regions, and districts;
  • Waters of special significance;
  • Providers of fisheries management;

  • Sampling of fish on the basis of licenses;
  • Fish kills; and
  • Conducted exams for professionals working in fisheries.

In order to ensure optimal implementation of fisheries management, the Institute prepares and conducts varied expert research in the context of its public tasks.

Expert research in the fisheries:

  • Set boundaries for fishing areas and fishing regions;
  • Establish the boundaries for the waters of special significance;
  • Provide the bases for the long-term program for freshwater fisheries;
  • Prepare expert research for the granting of concessions and
  • Focus on other expert bases, relevant to freshwater fisheries.

An integral part of the Fishing Cadaster is also a Geographic Information System (GIS), which enables the analysis and preparation of different expert research based on geo-positioning data.

As attachments to the executive acts, the following digital layers have been prepared:

  • fisheries areas;
  • fisheries regions;
  • fisheries districts and the method of implementation of fishery management in them, and
  • waters of special significance.

The following digital layers are also in preparation:

  • fish farms
  • Commercial ponds and
  • spawning grounds for individual species

For the preparation of detailed plans, planning documents at the national and local levels have been prepared under different sectoral digital layers.

Fishing Cadaster online

Since the beginning of 2010 the Fishing Cadaster has worked via the internet. The web application "Ribkat” enables different users to access and use the data of the Fishing Cadaster via the Internet. Angling clubs can now access the data prescribed for the annual program and annual report on the implementation of fisheries management, directly from the web application. The application also allows them to view data, prepare various analyses, and export data to MS Excel.
