I have a 1/2 acre pond that I would like to turn into a kid catching lake.

Current conditions

Alkalinity 9.
Small bream and bass stocked now ( never seen more than a 8 inch bass)

Plan

Lime to get alk up.
Put a feeder on the lake
Stock 50 catfish as large as I can get.
Stock 50 smaller cats
Transplant some 1lb bream from an existing 100 acre lake.

Questions

Is it ok to lime in the winter.
When should I stock catfish? Would like to do so ASAP
What are the other holes in my plan?
