In brackish waters of a creek of Guanabara Bay, the author points by the first time the presence of Chlamydomonas reinhardi, Eutreptia lanowi, Oscillatoria putrida, O. limosa, O. chlorina that were unknown in our waters; such biologic indicators proved themselves pollutional conditions, so bad a stark-mesosaprobic regime. Other news are plankton analysis by the Standar methods, of two most expressive samples of water masses;also the mobility of the plankters are measured in micra by second.
