My pond is being overwhelmed by "blanket weed" - thin hair like algae that clumps around the plants and eventually turns the pond into a swamp. The most common treatments involve the use of chemicals or barley straw, but there is one other method that I discovered after lots of googling.
I have bought 2 Grass Carps, which are a species of vegetarian fish. They can consume up to 3 times their own weight of vegetation in a single day, and can grow up to 45 lbs if given enough space and food. They have already made a start on my blanket weed, and when they have gobbled it all up, I'm going to catch them with a net and cook them up with some fresh herbs and few new potatoes. Maybe.
