Abstract:

Four similar one-quarter acre ponds were stocked with 1500 bluegill fingerlings and 100 bass fingerlings per acre in the spring of 1950. Two of the above ponds were enclosed with board fences and stocked with slider turtles, Pseudemys scripta scripta (Schoepee), at the rate of 100 per acre. The four experimental ponds were fertilized and managed identically. The ponds were drained in the fall of 1950, and the average yield of fish in the ponds containing turtles compared to that in the control ponds. It was found that the average yield of fish in the ponds containing slider turtles was 257 pounds per acre while in the control ponds it was 263 pounds per acre. Various types of traps were tested to determine which was the most effective in catching turtles. Wire baskets, which were similar to fish baskets but modified so as to permit the entrance of large turtles, were the most effective traps. Slider turtles were collected from various ponds in Central Alabama. The contents of 58 stomachs were analysed and it was found that the food consisted of approximately 80 per cent vegetable matter and 20 per cent animal matter. Filamentous algae made up approximately 45 per cent of the total diet while fish constituted less than 3 per cent.
