An interesting point on the length vs weight dynamics of LMB.


A number of years ago fisheries scientists studying trophy LMB and attempting to find a formula to accurately determine (estimate) weight based on length and girth made an interesting finding. There were after looking at thousands of trophy fish from diverse areas 2 distinct types of LMB (not talking about genetics here). The formulas devised used one calculation for short fish and another for long fish. All were very healthy and both formulas gave accurate weight results. Keep in mind that RW are just one measure and are based on a universal (set in time) average. I did not pursue this further at the time and never saw the specifics beyond the formulas.

As Jim noted LMB and other fish can adapt (plasticity) as that is in their genetics and that includes both feeding and nutrition. Some don't make it and others adapt and do. That is how a populations change over time.
