Limnology is a discipline that concerns the study of in-land waters (both saline and fresh), specifically lakes, ponds and rivers (both natural and manmade), including their biological, physical, chemical, and hydrological aspects.
François-Alphonse Forel (1841-1912) established the field with his studies of Lake Geneva. Limnology traditionally is closely related to hydrobiology, which is concerned with the application of the principles and methods of physics, chemistry, geology, and geography to ecological problems.

"Duckweed refers to species of free-floating, stemless aquatic
plants touted for their uses in waste treatment, animal feed and
pharmaceuticals. Known by botanists under the family of Lemnaceae,
duckweed is believed to be both the world's smallest-flowering and
fastest-growing plant. It grows 20 times faster than corn, doubling in
size within a few days through a natural cloning method. It can tangle
the lines of recreational fishermen casting near duckweed along still,
freshwater areas where the plants thrive. Duckweed can be used to
cleanse wastewater, reducing nitrogen and phosphorous in human waste.
Duckweed produces more protein on average than soybeans. It can also be
used to feed exotic fish being raised for aquaculture."
