I have found these links for the plant you will have to click on the state in which you live for information about the plant. DUCKS like eating the fruits

Grass carp are illegal in many states.
Some western states do not allow grass carp to be planted in their waterbodies, other states allow some limited stocking with permits. Check with your state and local jurisdictions to determine if stocking grass carp is legal for your state.

Answer 2

If you have anyone in your area that sells fish for stocking ponds, ask them if grass carp will eat it and clean it for you. I have used then before with good results.

Answer 3

Do you have another name for this weed? I do not find "calatrice" listed. If so, please do an Edit and give us the other name.

Thank you.

You could take a sample to a nursery and see what they recommend.

Answer 4

Answer 5
