Agree with opportunity. Neither predator nor prey have the ability to reason but are more reactive. ....
Yes! This makes a lot of sense to me. It seems intuitive to me that there is a minimum size BG must attain to be of interest to LMB and trigger an attack (reactive). For purpose of discussion, assume that is 3 inches for larger LMB. Arguably, there are significantly more 3 inch BG in a typical pond's population than each larger size class, which implies that there is an increased opportunity for LMB to feed on 3 inch BG than larger. I wonder if the stomach content of LMB in pond's where the BG are fed pellets, and BG grow more quickly, have a corresponding increase in size of stomach contents as the population density distribution of the size classes of BG is skewed toward larger sizes.
