Dataset description

The fish regions are a longitudinal division of rivers based on the sequence of typical cönoses (living communities). The fish habitat is divided into the following biocenotic regions: Epirhithral (upper trout region), metarhithral (lower trout region), hyporhithral (ash region), epipotamal (barb region) and metapotamal (breathing region). In the national assessment scheme currently applied, the waters of the hyporhithral (ash region) and the epipotamal (barb region) were broken down into two and three regions according to the flow and width of the water. The fish regions and the fish guides assigned to them in combination with the river bioregion provide the water-type reference status for fish fauna. The state of data shall be in line with the 2015 National Water Management Plan (NMP) and shall be updated as appropriate after the publication of the NGP 2021.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
