I am examining potential differences in functional responses between two fish species and want to supplement this with a basic comparison of their activity level. I do not need to examine specific behaviours (e.g. chases, approaches) so I wondered if I could visually divide the experimental tank into a grid and measure the number of line crosses per unit time as a proxy for activity level?
Any other basic approaches would be greatly appreciated!
This is a simple fairly standard method - useful to make a video and then take time to study line crosses at your leisure rather than sit and record manually
Malcolm's idea of making a video is quite good enough.I would like to add one point.Activity of a fish as observed is through movement by fins & its eyes. So number of times a particular fin makes a movement as well as eye ball movement can be measured from both the sides.
