Todd :
I assume the 3in LMB in the tilapia ponds were eating the new tilapia offspring not the brood fish. Any evidence of the LMB when small 3-4in getting beat up by the parent tilapia? Did most of the LMB survive to 1lb? Was that 1 lb. up to the point of the cold induced tilapia die off or past that time? Do you think the #s in the production pond made a big difference ?
I realize the answers may not be known. I am thinking as I go about of the possibility of a FH replacement or augmentation method by stocking adult tilapia with the FH , later in larger sizes BG/RES then LMB.
