1899 Amer. Naturalist 33 339 This potamoplankton is characterized by Schröder as variable, being at a minimum during the winter when the streem is frozen, and in March when it is at flood and full of silt.
1902 Ann. Bot. 16 584 These backwaters thus form a kind of transition from the typical Potamoplankton of the flowing river to the Heleoplankton of the ponds of the Thames valley.

1991 R. S. K. Barnes & K. H. Mann Fund. Aquatic Ecol. (ed. 2) i. 24/1 Many diatoms grow attached to the hard bottom in the upland reaches... In lower reaches, a true ‘potamoplankton’ develops, with diatoms and rotifers being especially important.
