Consequently， copepod size and species composition can affect fish larval survival and therefore fisheries resources. However， the counting and sizing of formalin-preserved copepods by conventional microscopic methods is time consuming. To improve the speed and convenience of measung copepod abundance and biomass density， we assessed the utility of bench-top VPR (B VPR)for counting formalin-preserved zooplankton samples. Plankton imaging speed by B-VPR was more than 1500 individuals/min， and the total measurement time required was significantly shorter than with the conventional microscopic method. Because the accuracy of identification and classification of zooplankton images by using computer analysis systems has not yet been optimized， we hypothesized that a combination of both computer and manual classification with selection of regions of interest (ROIs) would enable efficient analysis. Copepod ROI image data obtained from B-VPR were compared with those taken by manual measurements under a microscope. B-VPR was capable of accurately estimating copepod abundance and biomass density using a conversion factor. We concluded that B-VPR enables zooplankton
