METHOD OF DETERMINING VERTICAL DISTRIBUTION AND DIMENSIONAL STRUCTURE OF ZOOPLANKTON IN WATER RESERVOIR

摘要

FIELD: agriculture.;SUBSTANCE: underwater video filming is carried out with a narrow frontal laser illumination of the organisms. The organisms observed in the frame are counted using a computer analysis of images in the video file or visually. At that all the organisms in the scanned water column are continuously recorded, and the individual depth of location and size of each organism, as well as the vertical distribution of the organisms of each size group are determined.;EFFECT: improvement of accuracy determining the vertical distribution of planktonic organisms and their dimensional structure.;2 dwg
