Hi Neha, Donax are great :) In my personal experience with bivalves, is that it is better to scan. In any case, scan or camera, the machine should be calibrated to check on distortions. I find that the scanners are cheaper and have less distorsion, no issue with scale, etc. thus I prefer it for marine invertebrates. With fish, however it is more complicated with a scanner, thus we use a camera.
I hope this helps, Cheers, M. 2018-03-16 9:51 GMT+01:00 Neha Sharma <n.sharma.4...@gmail.com>: > Dear All, > Greetings!
