A grass carp will likely eat fewer animal products when weeds are gone than tilapia. IMO the tilapia will not eat enough PK shrimp to be noticeable in the overall production of new shrimp. If you are not growing PK shrimp with tilapia in the pond your habitat is lacking. Loss of weed habitat = loss of PK shrimp.
