Mesotrophic
MAIN INDEX
Mesotrophic is an adjective used to describe the level of biological productivity of a
waterbody.
Many professionals classify levels of
biological productivity using four trophic state categories: oligotrophic, mesotrophic,
eutrophic, and hypereutrophic. Of the four trophic state categories, the
mesotrophic state is defined as having a moderate level of biological productivity. (The prefix
meso means "mid-range".)
A mesotrophic waterbody is capable of producing and supporting moderate populations of living
organisms (plants, fish, and wildlife).
Mesotrophic waterbodies generally have:
- Moderate nutrient concentrations
- Moderate growth of algae, aquatic macrophytes, or both
- Water clear enough (visibility of 8 to 13 feet) so that most swimmers are not repelled by its
appearance and can generally see potential underwater hazards.
