Information
Ecological parameter: rheophily (habitat)
Parameter group: habitat related parameters
Explanation:
The parameter describes the affinity of species regarding the flow conditions. Three classes are defined.
Type of assignment: single category assignment system ()
A description of the coding system can be found here Abbreviations/Coding Systems
Abbreviations:
| Category name: | Abbreviations: | Explanation: |
|---|---|---|
| rheophilic | rheo | fish prefer to live in a habitat with high flow conditions and clear water |
| rheophilic A | rheo A | fish prefer to live in a habitat with very high flow conditions and clear water |
| rheophilic B | rheo B | fish prefer to live in a habitat with moderate flow conditions and clear water (close to eurytopic) |
| limnophilic | limno | fish prefer to live in a habitat with slow flowing to stagnant conditions |
| eurytopic | eury | fish that exhibit a wide tolerance of flow conditions, although generally not considered to be rheophilic |
