We stocked what I guess you would call a full load about 10 years ago in my 20 ac. pond. Lusk said at the time it was about 4 to 5M and they were 1.5 to 3" I would say roughly. It is the best thing we ever did and helped all species tremendously. Have never had a "die off" that I am aware of. The only real problem I have now is the water turkeys, cleaning me out. Thank goodness the shad are prolific and reproduce multiple times per year. I would strongly recommend stocking tfin and feel sure you will be happy with the results......
