Some snake found its way into my pond. I heard that local snakes will eat the fish. The pond is 1/2 underground and 1/2 above ground with a 2 ft high brick wall all the way around. Is there some strategy I can use to keep snakes out?
The snakes stop eating fish when there are no more fish. You can try killing the snakes, but they are fast. I did kill one by putting a fish trap under the water; the snake went in, could not find the opening and drowned. If the snake is slow and mostly black, it is probably a cottonmouth, which does not eat many fish, but you shouldn't mess with it.
