  ImageJ is also available as FIJI, which may be easier to download and update (also free). There is a separate listserv devoted to ImageJ / FIJI questions outside ResearchGate that can be very helpful. It is considered best to have studied some tutorials before posting a question there, and also to attach the image in question. There are many plugins for segmentation; you might look first at k-means, color thresholding, and SIOX.

  These two citations are the closest I know to your topic. Chang, S-K., Lin, T-T., Lin, G-H., Chang, H-Y., and Hsieh, C-L. 2009. How to collect verifiable length data on tuna from photographs: an approach for sample vessels. – ICES Journal of Marine Science, 66: 907–915. D.J. White, C. Svellingen, N.J.C. Strachan. Fisheries Research 80 (2006) 203–210. Automated measurement of species and length of fish by computer vision. If you have a good program that can measure length well available in ImageJ, FIJI, or some other open source, that could be a great help to many of us. I am using other programs to identify individual fish from their spot patterns (like fingerprints), but measuring length when the camera location moves is giving me trouble. charles dot anderson at state dot mn dot us.
