Ecological parameter: salinity preference I

Parameter group: habitat related parameters

Explanation:
The parameter indicates the salinity preference of a species, i.e. the proportion of dissolved salts in the water. Basically, there are three categories. Species with no specific classification belong to the category "fresh water".

Classification system: single category assignment system
