I was able to get Tilapia that were in the 8" range. My thinking is that with a pond that is larger like ours fewer big ones are better than lots of smaller ones. Survival rates will be higher and spawn sooner than the smaller ones that will become snacks. It might take a little longer to get the full benefit but saves a lot of money on the front end. When I add gizzards I will use the same process.

ML will surely have more info that may be of help to you since he is located closer to you.
