Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? forage in an est. old lake- I would like opinions

Myself and 6 others have a 28 acre lake along with the farm for hunting. The lake is as old as I am, and thats 53. I have started taking out peanut bass less than 14". It use to be eat up with crappie, and about 15 years ago,, I got out about 500 of those, and that helped a bunch.
There is a decent bluegill population in the lake, but maybe more shellcracker. Now I have talked to Lusk and Grimes, and Lusk seemed to think as far as very limited money goes, the following is a good idea to get some forage in there and fatten up the bass. I got 120 dozen shiners 3-5" and turn them loose in the lake. Also, at the same time, I let 40 dozen small shiners loose for immediate forage. And it was that--an hour later, they were getting chummed up by bass and maybe a crappie or few. One week later, I got 120 9-11 inch gizzard shad and released them into the lake. I know the shad will spawn once for sure this year. Worse case, I may have to seine out some shad in 15 years if they reproduce too well.
The lake has a good bass population in it,, and I want to give them plenty to eat. Do you guys like this , or do you see fatal mistakes. Others want us to spend a lot of money and shock the lake and do an analysis...We do not have lots of $$$ to get technical, 1,000.00 to shock the lake. Thus far we have spent 625.00 One rainy day in early April this year, I threw a buzzbait and caught about 60 bass. Of those, 16 were peanuts, I took them out. Of the rest, they were an average of 3 lbs , and several 4-6 lbs. Three days before all this, I caught a 10.5 that had spawned. She was flat, and very long, I thought she may weigh 11. She had a big head, but a little poor. Most of the 3's, and 4's were healthy looking. I had prefer you private e-mail me to n4gnr@windstream.net
I thank you for your time and opinions. Dan...in n.e. Ga.

If both Lusk and Grimes say something, I tend to go along with them.
