Eric,
Thanks for the reply!
Am I to interpret from this info that as a pond ages the genetics of the fish population gets "stale" so to speak and thus the catchability of the fish population also reduces significantly.
The implied solution to reduced catchability overtime is to periodically introduce a different genetic population including northern strain LMB and maybe some F-1. Now, I may have over-simplified things- but am I on track?
How often would you introduce new NLMB or F-1 to retain good catch rates?
Thanks again,
Al
