In my last several years after introducing Blue Tilapia as a very viable pond management tool, I have had exactly ONE complaint about their activities.
The customer's kids wanted his sand beach area to NOT stink of hydrogen sulfide (hydrogen sulfide gas from anoxic waters under the sand). His kids "complained" they had to rake the nests that male tilapia made in the sand. I asked if the Tilapia cleaned the sand and removed the odor. He said yes, and that his kids just didn't like the nests. Seems to me, he just has lazy kids, since his water quality was improved.
