awesome idea... might be highly dependent on light conditions, but I'd be keen to learn more about your work.

You asked same question in different places and got similar answers. Value time other people spend on you and at mark some answers as accepted. People do not get even points from you otherwise. Same applies to other questions you asked in this site.

To detect eye (of fish or human or anything else), I think the best approach (with OpenCV, at that time) is to train a Cascade classifier. You need samples, both positive and negative to train your classifier. You could use the Haars features or the LBP with the C++ interface (which you should used!). Almost everything is code for you, you just have to provide data as input, with the label. For the detection, see this page. Enjoy, and let us know if it's working for fish quality!

If it's working, you definitively should make an Android apps, it would be perfect for fish market... ;-)
