Salinities less than 5ppt in the lower 40 miles of the Potomac River killed 50% of the marketable oysters after Agnes, and blocked reproduction that year. Because saltier water is heavier, the oysters near the surface suffered low-salinity water for a longer period of time.alinities less than 5ppt in the lower 40 miles of the Potomac River killed 50% of the marketable oysters after Agnes, and blocked reproduction that year.

When fresh water is added for example by rivers, or precipitation, the salinity of the ocean will decrease. That explains why some oceans are less salty than others Factors like the melting of ice, the inflow of river water, rain, snowfall, evaporation, wind, wave motion and currents affect the salinity. cubic foot of seawater contains about 2.2 pounds of salt, but 1 cubic foot of fresh water from Lake Superior contains 0.01 pound of salt, or about one sixth of an ounce. That means sea water is about 220 times saltier than a fresh water lake.
