Dear colleagues, I am currently thinking of using a morphometric analysis in order to evaluate ontogenic growth patterns in a large sized fish species.
Most of the papers I have read on large fish morphometry rely on box-truss distances and use calliper measurements, or use digital images and geometric morphometrics methods, considering mostly a 2D view. However, I am experiencing some difficulties in establishing a methodology that can be correctly applied to juvenile (e.g. 200 mm) and adult (over 90 cm) forms, where the 3D component may play a significant role and unbent 2D images are difficult to acquire. Can this be made by considering some kind of 3D truss in calliper measurements? is there a specific procedure for capturing useful digital images of fish within such large size range? Can anyone give me an advice on this issue?
