Most fish keepers are always anxious to see the new life that will be born in their aquariums or ponds. But things can be difficult if a spawning season is proving to be difficult because you have been trying hard to get your fishes to spawn, but they just weren’t cooperating.
You must have tried all kinds of tricks, but nothing seemed to work. Some fish keepers even go as far as buying a special heater that was supposed to help stimulate spawning, but it didn’t make a difference. The fishes just wouldn’t do it.
You don’t have to feel discouraged because it’s totally understandable that you have been working so hard to get things to work and it just wasn’t going well. But the question is have you tried simulating your fish’s natural habitat? Have you tried to re-adapt their surrounding to look like their natural habitat in the wild does when it’s time for spawning?
Well, that could be the solution you are looking for and spawning mops could help you do the trick and encourage your fish to start spawning.
What is a Spawning Mop?
A Spawning Mop also known as Breeding Mop is basically a bundle of green yarn, wool, or string that has been tied together to form a big mop head like strings or yarn to help encourage fish spawning so female fish can lay their eggs. It can be made from different materials like nylon, acrylic, cotton, and even wool. A spawning mop can be easily created at home, and can also be bought from most pet stores.
What Does A Spawning Mop Look Like (Spawning Rope)?
The picture below is an example of what a Spawning Mop also known as a Spawning Rope looks like. It’s basically just a big green mop head with a lot of stringy material hanging down from it.
As you can see, Spawning Mops are very easy to make and can be made from different materials. You can even buy them from most pet stores.
How Does a Spawning Mop Work?
When female fish are ready to lay their eggs, they will often look for places where there are lot of vegetation and plants to help them hide their eggs. The female fish will lay her eggs in amongst the plants and then the male fish will come along and fertilize them. The fry will then hatch and have plenty of places to hide in the plant vegetation from predators as they grow big enough to fend for themselves.
The problem is that most aquariums or ponds don’t have the right kind of plants that are required for spawning. This is where a Spawning Mop comes in to help encourage fish spawning.
Spawning Mops works by simulating the look and feel of plants that are found in a fish’s natural habitat. But instead of using plants, they use materials like yarn, wool, and cotton cord which is usually green to stimulate a plant environment lookalike.
The spawning mop is then left in the aquarium or pond so that the material of the mop will catch the eggs as they are released, and it will also help to keep them safe until they hatch.
Eventually, the material of the mop will start to disintegrate and fall apart which is totally fine because as it does, it will release bits of material into the water which will help to encourage your fish to start spawning because it simulates their natural spawning environment.
It’s recommended to leave the spawning mop there in the pond or aquarium until the spawn has been completed. After the spawn is complete, the mop can then be removed and the fry can be left to fend for themselves.
What You Need To Make A Spawning Mop For Koi Fish:
Below are the 5 items you need to make a koi spawning mop also known as a breeding mop:
- Green yarn, thick green wool, or green cotton cord.
- Cork (perfect for floating mop). Alternatives are Polystyrene (perfect for floating mop), Rock (perfect for sinking mop), or Suction cup (perfect for a mop that attaches to the wall).
- A Scissors or sharp knife to cut the yarn
- A Journal or cardboard in size of the journal.
- A clean, dry container to soak your mop in hot water
DIY: How To Make Spawning Mops (Breeding Mops)
Follow the instructions below to make the perfect DIY spawning mop (koi spawning rope):
Total Time: 5 minutes
1. Position and Place The Yarn
Position and place a strand of yarn across the top edge of your journal. If you are using a cotton cord, you will need to singe the ends with a lighter to prevent fraying.
2. Wrap and Wind The Yarn
Wrap and wind the yarn across the journal several times for about 60 -100 times or more, depending on how bulky you want the mop to be.
3. Create A Loop
Cut the leading strand of yarn, leaving a 6-inch (15 cm) tail. Then use it to tie a loop in one end of the mop bundle to create a hanging loop and secure it in place.
4. Remove from Journal
Now remove the yarn from the journal and cut the wrapped yarn into two. Check for any imbalances and trim the mop to an even length if needed.
5. Add Cork or Polystyrene For Buoyancy
Cut a piece of cork, Polystyrene, or rock, and use strands of yarn from the mop to tie it at the center of your mop. This will help the mop float or sink as desired.
6. Soak in Boiling water
Now soak your yarn in boiling water for about 10-15mins to kill any existing bacteria, get rid of the dye that might bleed from the yarn into the aquarium, and also get air out of it so it can sink properly.
7. Put in your Aquarium or Tank
Your aquarium or tank is ready for your new spawning or koi breeding mop. You can place the DIY koi spawning rope anywhere in the tank.
8. Remove and Store
When you are done using the mop for the spawning season, do remove it from the tank, dry it, and store it in a clean container until you are ready to use it again.
Koi spawning mops are an easy and convenient way to breed koi fish. With a little bit of yarn and some polystyrene, you can create a floating or sinking mop that will provide a safe place for your koi to lay their eggs. By following the instructions above, you can create a spawning mop that will last for many spawning seasons to come.

When is the Best Time to Use a Spawning Mop?
The best time to use a spawning mop is typically when the water temperature starts to rise in springtime. This is because most fish will start to spawn when the water temperatures increase and using a spawning mop can help to encourage them to start spawning if they haven’t already started.
How To Use A Spawning Mop for Breeding Fish?
Spawning mops are an easy and effective way to collect fish eggs and breed them. The mop acts as a substrate for the eggs to attach to, and then can be easily removed and placed in the aquarium.
To use a spawning mop:
- Simply make your mop using the steps above
- Tie the mop to polystyrene, a rock, or other objects in the aquarium.
- The fish will then lay their eggs in it and the eggs will attach to the mop for the male to fertilize
- The eggs will hatch within a few days.
- Once the fry are free-swimming, they can be removed from the breeding mop and placed in a separate aquarium or rearing tank.
Spawning mops are an easy way to collect fish eggs and can be reused multiple times. They are a great option for those who want to breed fish but don’t have the time or space for a dedicated breeding setup.
