Floating Rope/Net for pond


Staff member
I have a 1-1.5 acre pond that is stocked with bream, bass, and sterile carp. The carp are there to keep the duck weed controlled, but they couldn't keep up with it by the end of the summer. I'm going to have to poison it next year.

In the meantime, I would like to build some sort of floating barrier that keeps the duckweed away from the area where the fish feeder is. It doesn't have to be a huge area. I'm thinking about driving some pvc pipes into the ground in front of the feeder, then wrapping some sort of floating rope/netting from the shore, around the pvc, then back to shore. Any ideas on what kind of material to use?

This is the feeder from behind. I need to keep the immediate area clear of weeds so the fish can eat.

I've seen PVC pipe itself connected to make a square that floated. Guess the air trapped inside the pipe was enough to make it float.
We use the 1 1/2 inch plastic duct with a compression coupling to make a floating circle to keep fish food in one area.The asian carp usually have to be replaced as once they get bigger they don't eat as much so you will have to add small ones every few years.There are some treatments that won't harm the fish
I had a duckweed problem this year too. I attributed it to extra nutrients from a fish kill the prior winter but that might be a stretch.

Anyway, on a different lake, we use pool noodles threaded on a rope. Look for the hollow ones. We cut them up as we're just marking a swim area. Marine rope should also be buoyant.
I wonder if it's getting by the rope where there aren't any noodles.You can get 1 1/2 or 2 inch rool pipe or duct and fasten together with a compression coupling.Then take 2 sticks of PVC fasten straight out from dock and tie to circle of pipe to keep in place
I've had luck just seining it out of the pond onto the shore then spraying all of it with 2-4-D. That needs to be done in the spring or early summer for best results. It starts at the shoreline so thats where you concentrate your treatments. Or you can just seine it and add more 10-12" carp. That noodle rope might work good to trap it in an area that has fewer trees or other plants that might get damaged by the 2-4-D when you pull it ashore.
Alligare Fluridone will kill it dead in its tracks and not harm a fish. My pond was covered and I treated it twice this summer and it stayed clear. You really want to treat the pond before the onset though so that it never happens in the first place. The chemical I mentioned is designed to slowly starve it to death so that all of the oxygen in the pond is not consumed by decomposition. It would still be wise to treat it before it comes on in the spring though just in case it turns out to be a really hot summer and the oxygen levels are down already. The chemical I listed is a generic for sonar. I search around on ebay and can usually treat my pond for $160 a year. Wind is your friend with duckweed, it thrives in calm waters surrounded by trees. I like my trees so I will keep treating my pond.;)
