I have often seen recommended a new mop head--the ones that are a group of fibers or strings, not the sponge kind. You can tie a cord to it and drop it in the pond, then use the rope to pull it out. Good luck with your eggs!

The mop thing never worked for me . The fish wouldnt go near it and if they did , you cant see whit eggs on a white mop. With the black netting you can easily see all the eggs on it . Every day Im getting 100's of them. I even watched some of the eggs hatch today . It takes 2 days for them to hatch. I think I'm going to need a BIGGER pond . Rick

I have a green mophead that I've never put in the pond because I've wondered if it was treated with something that would hurt the fish. Also, I saw a recent post on this forum suggesting that WOOL yarn be used for the same purpose because wool yarn does not disintegrate like the mop heads. The person posted that they tie the yarn tightly in the middle then cut the loop ends to make a "mop head" out of it. I was planning on trying the wool yarn but haven't been able to find any --- all the yarn I've seen is acrylic. (Guess I have to go to a sewing/craft store?)

Ronnie, twas me who posted about making spawing mops out of hanks of wool.Acrylic wool is okay to use. I does tend to float on the surface for a day or so until it becomes water logged, then it sinks.
Attach it to a rock or whatever, to keep it just at surface level.
If you do not want to raise young fry or you don't want your pond to be overstocked, remove the spawning mop out from the pond daily when the fish are flashing.
Dip it completely into really hot water, which will sterilize the roe.
Then the mop place it back into the pond, were the adult fish will eat the roe.
They eat it anyway but some of the roe always makes it into fry, the sterilizing does a better job and keeps the pond population down more effectively.
