I'm against non-native fish in the U.S.

I too have seen lakes overtaken with elodea. But they were very small, 10 acres or less. I think a 52 acre lake would be able to cope with the plant.

Now I can't be sure that it was elodea, but I was scuba diving in Dale Hollow Lake in Tennessee, and it was supporting a tremendous amount of fish. I saw largemouth bass, bluegill, crappie, and other smaller fish just hovering above the plant in about 20 feet of water.

Can anyone give me any recommendations on how to improve bass, crappie,baitfish (fathead minnow and golden shiner) and catfish spawning habitats?
