     Target fish species are recorded to help properly manage, regulate, and protect migratory fisheries by accurately monitoring numbers, size, and species of fish at specific fish passages during migratory seasons. After capturing images of different fish species, the contour of each image is extracted to form a closed curve for shape analysis. A new shape analysis algorithm was developed for removing edge noise and redundant data points such as short straight lines. A curvature function analysis is used to locate critical landmark points. The fish contour segments of interest is then extracted based on these landmark points for species classification. By comparing individual contour segments to the curves in the database, patterns can be accurately matched to identify the fish species.
