No bummer, thanks for the heads up! I will be in contact with the extension agent ... I needed something to do anyway!!!
Good for you.

I don't have a pond. I wish I had a pond. I have researched everything I need for a pond for about 30 years! I have everything I need except the $$ to dig the hole!

I grew up on a small lake. As a Boy Scout I did a stint with the DNR killing all the fish in the lake in the spring and then restocking it in the fall. I did a study in it before, during and after. Around here they almost always stock lakes with bass and bluegill in proportional numbers. The theory being the bass keep the bluegill in check. They also stock channel cats in lakes with established logs, stumps and structure where the cats can hide the babies. Otherwise, they are just stocking the cats for catch and release they will rarely reproduce.
Unfortunately, around here at least, there is a phenomina where they stock bass, bluegill and channel cats... three months later you will catch perch, pike and crappie... due to people wanting those fish instead of bluegills. They throw them in. Perch and Crappie rarely do well in small lakes. One perch can lay 60,000 eggs. Both eat minnows. No minnows and they turn to eating each other and bluegills. Then about a year or two after the restocking they start seeing huge schools of shad!

Turns out it is bass fishermen that are the culprits for the shad. They think they know how to make the bass bigger... by releasing shad into the lake. What happens is the shad reproduce faster than the bass can eat them. Once a shad gets over 8-10" the bass don't touch them. Then all those shad eat the food that the bluegills would normally eat and the bass eat the shad instead of the bluegill. The bluegill are small, the shad are everywhere and the bass never get to large sizes because there are too many fish eating the forage.
Any given body of water can support X pounds of fish life depending on the nutrients suplied to the water. So, for example, let's say your pond can support 1000# of fish. That can be 10,000 on tenth pound fish, or 1000 one pound fish or 100 ten pound fish or any combination of the above to get your 1000# of fish. Its kind of neat to study. I wish I had my own pond to experiment with.
