Abstract: Productive oyster reefs in Mississippi Sound are subject to seasonal floodwaters. In 1945, lowered salinity caused mass mortality on the reefs. The mortality at that time was attributed to fresh water discharged from the Bonnet Carre spillway on the Mississippi River. This report discusses the biological and hydrographic data collected during the flood period in 1950. Comparison of 1950 with previous years indicates that salinity levels in Mississippi Sound result from a combination of factors, no one of which can reasonably be cited as the cause of the oyster mortalities. |
