Document Type



Investigations were made in Mississippi Sound and adjacent waters from March 1968 through March 197 1 to record the occurrence and seasonality of planktonic cnidarians. About 700 plankton samples were taken from estuarine and oceanic areas. From these samples, 26 species of hydromedusae were identified, 12 of which were collected from Mississippi Sound. In addition, 25 species of siphonophorae were identified from Mississippi waters, although only 6 species were collected in Mississippi Sound. From an examination of about 500 trawl samples taken during this period, 10 species of Scyphozoa were found in Mississippi waters, 6 of which occurred in Mississippi Sound.
