What Are Bloodworms Used For?

A detailed look at bloodworms; what they are used for, what they look like and how to breed them.

What Are Bloodworms Used For?

You might have heard of bloodworms before, especially if you keep your own fish in a home aquarium. This might also be the case if you are an avid fisherman. There is no doubt about the fact that these little worms do not look nice.


They actually look rather repulsive to say the very least. However, this does not mean that they cannot be useful in certain ways. Let’s take a closer look at the bloodworm, what it is, what it is used for, and how you can breed and raise them at home.

What Are Bloodworms?

Bloodworms are actually the larval stage of another insect, the chironomid midge. This is a type of fly, one that usually does not bite humans or other animals. Interestingly enough, bloodworms, the larval stage of this fly, are actually carnivorous.

These ugly little worms have a large proboscis with 4 hollow jaws. These jaws contain venom glands which they use to incapacitate and kill their prey, making quick snacks of them. They only eat other small insects and the larvae of insects. However, their bit is actually painful to humans. They have been known to cause severe allergic reactions, but no worries because their bite will not kill you.

What Do Bloodworms Look Like?

These things look slimy, they are red, partially transparent, and they can grow to 14 inches or 35 centimeters in length if they are healthy and left to grow. They are usually always found underwater, living in sandy, muddy, and silt covered bottom layers of intertidal or sub-tidal regions. Although they can handle a bit of salt in the water, too much of it will kill them.

Bloodworm Uses

When it comes to the uses of bloodworms, there are not really too many. To be honest, most people do not want to look at these nasty little things, let alone touch or breed them. However, there are people who do not mind them, in which case they do have a few good uses.

Fishing

Their main use is most often for fishing, especially for things like bass and trout. Their meaty texture is something that fish love, especially big predatory fish. This is why the main market for bloodworms is the fisherman market. Fisherman often use these slimy little bloodworms for baiting their hooks.

Aquarium Fish Food

However, many people who own aquariums also use bloodworms to feed their fish. These things are rich in protein and minerals, making for healthy snacks for fish that need lots of protein in their diets. Of course, these worms are aggressive and carnivorous, so you do not want to let them grow to their full 14 inches in length before feeding them to your fish, especially if the fish are small.

These worms could potentially do some serious damage to smaller fish when they are fully grown. Yet, this is why people do not feed fully grown bloodworms to their fish, due to the dangers they can pose.

With that being said, young bloodworms make for the perfect meaty treat and an awesome break from fish pellets and fish flakes. Needless to say, you will probably want to wear a thick pair of gloves when handling these things.

How Long Do Bloodworms Live?

Bloodworms are pretty interesting creatures, and this question is actually a little difficult to answer. The thing is that first, the eggs of the midge are laid. After a few days, these eggs hatch into the larvae, which are the bloodworms.

These bloodworms will then eat as much food and organic matter as they can for up to 7 weeks. After 7 weeks of being a bloodworm, it will enter its pupal stage, in which it will stay for about 3 days, after which the fully developed chironomid midge will emerge.

Therefore, if you are looking to breed and raise bloodworms in order to feed your aquarium fish, they should be fed to your fish in the first 4 weeks of being bloodworms, if not much sooner, as if you leave them for too long, they may grow too large for smaller fish to consume.

In other words, these things do not have a long shelf life, and thus, breeding needs to happen constantly if you want a steady supply of usable bloodworms to feed your fish.

How To Breed Bloodworms

Breeding bloodworms is honestly quite difficult. No, raising them is not hard. In fact, these things are very low maintenance, and unless you burn them alive, there is pretty much no way you can mess up raising a bunch of bloodworms.

However, with that being said, breeding them is a bit of a different story. At any rate, let’s go through a quick step by step process on how you can breed and raise bloodworms without too much trouble.

  1. The first thing that you need to do is to get all of the proper equipment. All you need are some plastic or glass containers, large ones, like old aquariums. The more of these worms you want to breed or raise, the larger the space needs to be. You will also need soil, manure, and water.

  2. Add a bunch of soil to the tanks and add a good amount of manure too. Farm animal manure is fine, but do not use waste from home pets like cats or dogs.

  3. Spray water onto the soil and manure, enough to get it really wet and muddy. Mix it around so it all forms a homogenous mixture. The manure is what the bloodworms will eat. Yes, they are nasty little creatures indeed.

  4. Now, the problem is that you cannot really go out and buy bloodworm eggs. That is not a thing, as most places do not want to sell them or do not bother with them. You will have to learn how to identify bloodworms eggs by yourself, go out, catch them, and then put them in the tank. They kind of look like miniature versions of frogspawn or tadpoles.

  5. Now, all you have to do is let them mature. Of course, if you want to breed them, you cannot feed all of them to your fish, and on a side note, if you are breeding them, you will need a heck of a lot of space. For efficient breeding, a large cluster of bloodworms is required, but when they are together, they will mate by themselves.

  6. Make sure to rinse the bloodworms in dechlorinated water before adding them to the housing or breeding tank in order to avoid potential dangers and complications. Now, simply keep letting them produce more bloodworm eggs, keep raising and feeding them, and take out enough to feed your fish, but not so many as to endanger the bloodworm population.

Conclusion

At the end of the day, while bloodworms may look super unattractive, they are pretty useful for feeding fish and they are not hard to raise either. Finding enough eggs to create and sustain a constant population is however not very easy.
