I have not harvested any bass out of my 5 acre pond for about 8 years. I have harvested bluegill and crappie. The crappie are huge most of them over 10 inches and the biggest part of them are 12-15 inches. I have an opportunity for a guy to come in and shock my pond to take out some bass. Most of the bass are healthy but are around 12-15 inches. Any suggestions on how to do this and what not to do since this is my first experience with shocking a pond and have just watched it on the internet. How many bass should I remove? The pond is 20 foot deep in many areas. Thanks.
