Very nice cyclic layout you got there as a renewable design. I'm totally jealous. Just make sure the damage caused by the turtle doesn't create an introduced consumption product for the creatures. We may not know it, but the food chain consuming the materials do.
If you have a large amount of fresh corn and soy bean, yes, try to alternate the dietary supplement. Rather than integrating dried and refined products, if the bluegills care to consume the fresh veggies, encourage them. But never exceed more than 50% of the total volume of their dietary consumption. There will be. A demishing return of growth and vitality.
