Fauna and Flora
The warm waters of the Sea of Galilee support various flora and fauna, which have supported a significant commercial fishery for more than two millennia. Local flora include various reeds along most of the shoreline as well as phytoplankton. Fauna include zooplankton, benthos and a number of fish species such as Acanthobrama terraesanctae. Fish caught commercially include Tristramella simonis and notably Tilapia, locally called "St. Peter’s Fish". In 2005, 300 short tons (270 t) of tilapia were caught by local fishermen. This dropped to 8 short tons (7.3 t) in 2009 due to overfishing.
However, low water levels in drought years have stressed the lake's ecology. This may have been aggravated by over-abstraction of water for either the National Water Carrier to supply other parts of Israel or, since 1994, for the supply of water to Jordan (see "Water use" section above). Droughts of the early and mid-1990s dried out the marshy northern margin of the lake. A fish species that is unique to the lake, Tristramella sacra, used to spawn in the marsh and has not been seen since the 1990s droughts. Conservationists fear this species may have become extinct.

Famous quotes containing the words fauna and/or flora:
“The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.”
—Louis Aragon (1897–1982)
“A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”
—Henry David Thoreau (1817–1862)
