Duckweed

I have a lot of duckweed forming in my pond (100'x50')again this year, just wondering if anyone knew a way to remove it without having to physically rake it out. I was reading about a chemical called diquat but not sure if it works or not. No chemical for algae seems to work, such as polypro.i tried getting grass carp but they can't sell them anymore, any suggestions?
Also the pond has aeration, and I was planning on putting trout in this yr

• On small ponds repeated raking or netting will keep the weed under control. Continuous removal is usually necessary
• On larger pools use a floating boom to sweep from end to end. Sweep at intervals from early in the season and continue until winter dormancy
• You can compost the removed weed
• Fit stop-boards at any upstream inlets to prevent duckweeds entering ponds or lakes
• Weed-eating water birds, such as domestic and ornamental ducks, moorhens and coots will provide some degree of control
• Grass carp will eat Lemna species
• Shading can reduce duckweed growth. This can be achieved by planting on the south side of the pond. Waterlilies and other plants with floating leaves can also substantially reduce the level of duckweed. The use of a fountain to disturb the surface may also help
