Fish I am looking at directly are LMB's. Today we will see a similar pairing of spotted bass as well as more LMB's. Thus far with the LMB's all have access to forage and feed in a given pond. Some appear to specialize on pellets while other on forage. The second pond we saw much less size disparity between the two groups but color holds. Difference in color I think owing to micronutrient level (forms of vitamin A in this case). Other differences also noteworthy, but not being looked at directly at this time. Innards and jaws appear different. I can tell if a fish is on pellets or fish my feel alone, even when size not an issue. These differences might have implications on long-term survival.
