I do think you have options. Monitoring pond populations as you noted ( catch, seine , elect , trap and observation are all good tools) is critical in all good ponds. It is the only way you can judge what is occurring. I do think you need more forage variety than just FH and TShad for a LMB pond. If you really want some big tilapia - what about getting about 25 adult male tilapia from Todd or someone who can 100% sex them and see how they do for a year. Add the small fish now including a few BG and RES in the mix. Then if you want next spring you can add some tilapia females after the other fish have spawned once. Then you would at least have a base established. Those BG, RES, and LMB could all help control the tilapia offspring. Monitor after that and adjust as needed to meet your goals.
