Why Is The Salinity of Mono Lake Too High for Most Fish?
The salinity of Mono Lake is too high for most fish due to its extremely elevated salt concentrations. This unique lake has a salinity level significantly higher than that of ocean water, which inhibits the survival and reproduction of most fish species.
According to the United States Geological Survey (USGS), salinity is defined as the concentration of dissolved salts in water, typically measured in grams per liter (g/L). Water with a salinity above 35 g/L is considered saline, while Mono Lake exceeds this, reaching around 70 g/L at times.
Several underlying causes contribute to the high salinity of Mono Lake. First, the lake is a closed basin, meaning it has no outlet. Water only leaves the lake through evaporation. Second, freshwater flows into the lake from surrounding rivers, bringing with it various minerals and salts. Over time, as water evaporates, these salts accumulate, increasing the lake’s salinity.
High salinity levels can be harmful to fish due to osmotic stress. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to one of higher concentration. Fish are adapted to balance their internal salt levels with their surroundings. In hypersaline environments, they struggle to expel excess salt, leading to dehydration and ultimately death.
Specific conditions that contribute to Mono Lake’s high salinity include limited rainfall, high evaporation rates due to its dry climate, and water diversion for agricultural use. For example, in the early 20th century, water was diverted from the rivers feeding Mono Lake for irrigation, thus reducing the inflow of fresh water and exacerbating the lake’s salinity levels. As a result, only a few salt-tolerant species, like brine flies and certain algae, thrive in Mono Lake, while most fish cannot survive in such extreme conditions.
