I am desperately in need of help. It's a long sad story so please bear with me. I have a 30 yr old, 2 acre spring fed pond with mud bottom in Nebraska. Approximately 7 yrs ago we had low water, high heat and major fish kill. We couldn't catch a fish for two years and suddenly we started catching 6" bass. Lots of them. This went on for two summers with no growth and no bluegill to be found. The ponds depth was 8' max and by the end of May it would be covered with so much weed that it was unfishable. At the start of the third season, I stocked the pond with 100 6" bluegill and 20 12" grass carp. The pond cleared up and the bass then grew to around 8". I caught and removed around 60-70 of these small bass that year. The next spring I added 120 channel cat, another 100 bluegill and a fish feeder which fed twice a day. It seemed like a great idea but the only thing that seemed to grow were the catfish and boy did they grow! I was feeding Aquamax at that time.That same year I raised the overflow up a foot and dug some deep holes around the edge with an excavator. The grass carp seemed to be doing a great job. Probably too great of a job. No moss, no weeds, and the water is usually crystal clear. The springs have kept it full although most of the ponds around here have been dangerously low due to the drought. Last year I added two five gallon buckets full of fathead minnows hoping to help my bluegill along and also switched to Gamefish Chow hoping to once again help out the gills. The 10 lb cats that I have now don't seem to want to let anything else eat around the feeder. I cut down 5 good sized trees and put them into some of the holes I dug around the edge in the previous years. Now I have come to this year and am still pretty discouraged. In my last three outings I have probably caught a total of 20 bass each time with an average length of 11 inches. My plan for this year is to possibly add more fatheads and maybe try to remove 60 bass or so.I want to try to thin out the catfish a little so that the other fish can get to the dinner table too. I have even considered an aerator. My primary goal is to restore the pond back to what it was when I was a kid and be able to catch 4 and 5 lb largemouth and 3/4lb bluegill. (In my area, a 5 lb bass is a lunker)I would rather work hard to catch a four pounder than catch 11"ers on a bare hook all day. I seem to have a fairly decent population of 5"-6" bluegill. If I fish with worms I seem to catch two bluegill to one bass. I have a feeling that I may have made a few mistakes in my attempt to improve the bass. Too many grass carp? Too many catfish? Not enough bluegill? Not removing enough small bass? Am I on the right track or should I try a new approach? I have sought information from all types of sources including the Nebraska Game and Parks, local hatcheries and a local biologist and they all seem to have different theorys on what to do. Any help would be greatly appreciated because I am about to give up! Thanks in advance.
