Title:Plankton Studies. 1. Methods and Apparatus in use in plankton investigations at the Biological Experiment Station of the University of Illinois.
Author(s):Kofoid, C.A.
Subject(s):biological science

Abstract:Less than ten years ago a new field of biological science was opened by the German investigator Hensen, namely, the quantitative examination of the " Plankton." This term was applied to all plants and animals floating free in the water and incapable by their own efforts of materially changing their position. Thus adult fish which ])rave the waves and stem the current would not be included in the plankton, while the passive eggs or the helpless fry would fall within the limits of the definition. Practically, the content of the term plankton as applied to fresh water is the sum total of its minute life, both plant and animal.
