Shouldn't I be trying to get bigger bass than 10-13 inches? That way they can eat 3 and 4 inch crappie and BG ? Or is a smaller bass size better right now ?
I don't think 10" to 13" are too large but you can add more of the smaller ones and have more predator encounters. You have cleared 225 lbs of space in your pond. Two things will happen, the fish still in the pond will grow ... and ... the BG will reproduce. Consequently, in order for the fish still in the pond to grow at their maximum rates, most of their offspring must be cropped by LMB when they are a smaller size. (ideally when less than 2").
To be reliable predators of 3" to 4" BG the LMB need to be 20" long. If the LMB biomass is concentrated in fish of 20", they will not keep up with BG YOY and BG (and BCP) growth will be slow. By concentrating the LMB in smaller fish you can have many more of them that must focus on the YOY. For example, for every 20" LMB you can have 8 10" LMB --- they weigh roughly the same in aggregate. So what you are trying to do by have many 10" LMB is to
prevent having so many 3"-4" BCP and BG.
