Application of Video- and Photomethods in Hydrobiological Research

Application of Video- and Photomethods in Hydrobiological Research The application of nondestructive methods such as video-transects and photo-quadrates to epifaunal communities of hard bottoms of Peter the Great Bay is analyzed in the present work. It was shown that video-transects gave more representative material than photo-quadrates for a greater area of scope. Two ways of transect shooting were considered, and a modified technique of counting the projective cover of the substrate by invertebrates with application of color segmentation and “AutoCAD®” software is suggested. The advantages and drawbacks of video- and photo-methods of epibenthos counting are considered. Russian Journal of Marine Biology Springer Journals
